+			Description: `Generate a password reset link for the given user and print it to stdout.
+
+The user completes the reset by opening the link in a browser and choosing a new password;
+the admin never learns or chooses the new password. The link is single-use and expires after
+one hour. This is an admin override of the self-service reset flow -- unlike self-service, it
+does not require the user to have a verified primary email (the token is bound to the user).
+
+With --send-email, the link is additionally emailed to the user's primary email address (this
+requires SMTP to be configured and the user to have a verified primary email).
+
+Example:
+  ntfy user reset-pass phil               # Print a reset link for user phil
+  ntfy user reset-pass --send-email phil  # Print and email the reset link

+### Install as a service
+If you want to install ntfy server permanently as a service, and your OS/distribution of choice doesn't offer a package,
+there are a few more steps to follow.
+
+Create the ntfy user and group:
+```bash
+useradd --system --home-dir /var/lib/ntfy --shell /bin/false --comment "User for the simple HTTP-based pub-sub notification service" ntfy
+```
+
+Depending on your init system, the following steps will diverge.
+
+#### On systemd systems
+Install the ntfy server unit file (which contains parameters to start the service at boot time):
+
+=== "x86_64/amd64"
+    ```bash
+    sudo mv ntfy_2.27.0_linux_amd64/server/ntfy.service /etc/systemd/system/
+    sudo chmod 644 /etc/systemd/system/ntfy.service
+    ```
+
+=== "armv6"
+    ```bash
+    sudo mv ntfy_2.27.0_linux_armv6/server/ntfy.service /etc/systemd/system/
+    sudo chmod 644 /etc/systemd/system/ntfy.service
+    ```
+
+=== "armv7/armhf"
+    ```bash
+    sudo mv ntfy_2.27.0_linux_armv7/server/ntfy.service /etc/systemd/system/
+    sudo chmod 644 /etc/systemd/system/ntfy.service
+    ```
+
+=== "arm64"
+    ```bash
+    sudo mv ntfy_2.27.0_linux_arm64/server/ntfy.service /etc/systemd/system/
+    sudo chmod 644 /etc/systemd/system/ntfy.service
+    ```
+
+Then notify systemd we have added a new service and start the service:
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl start ntfy
+```
+
+#### On OpenRC systems
+Install the ntfy server service script:
+
+=== "x86_64/amd64"
+    ```bash
+    sudo mv ntfy_2.27.0_linux_amd64/server/ntfy.openrc /etc/init.d/ntfy
+    sudo chmod 755 /etc/init.d/ntfy
+    ```
+
+=== "armv6"
+    ```bash
+    sudo mv ntfy_2.27.0_linux_armv6/server/ntfy.openrc /etc/init.d/ntfy
+    sudo chmod 755 /etc/init.d/ntfy
+    ```
+
+=== "armv7/armhf"
+    ```bash
+    sudo mv ntfy_2.27.0_linux_armv7/server/ntfy.openrc /etc/init.d/ntfy
+    sudo chmod 755 /etc/init.d/ntfy
+    ```
+
+=== "arm64"
+    ```bash
+    sudo mv ntfy_2.27.0_linux_arm64/server/ntfy.openrc /etc/init.d/ntfy
+    sudo chmod 755 /etc/init.d/ntfy
+    ```
+
+Start the ntfy server service:
+
+```bash
+sudo rc-service ntfy start
+```
+
+Add the ntfy server service to the default runlevel (so that it starts at boot time):
+
+```bash
+sudo rc-update add ntfy default
+```

+This chart is **not** maintained by the ntfy developers.
+
+!!! warning
+    The HelmForge project is young and maintained by a small community. Review the chart before deploying it,
+    and use it at your own risk.
+
+```bash
+helm repo add helmforge https://repo.helmforge.dev
+helm repo update
+helm install ntfy helmforge/ntfy
+```
+
+Alternatively, install it directly from the OCI registry:
+
+```bash
+helm install ntfy oci://ghcr.io/helmforgedev/helm/ntfy
+```
+
+Because ntfy's default SQLite storage is single-writer, run the chart as a single instance rather than
+treating it as a horizontally scalable deployment. See the [chart documentation](https://helmforge.dev/docs/charts/ntfy)
+for the full list of configurable values.

 # Privacy policy
 
-I love free software, and I'm doing this because it's fun. I have no bad intentions, and **I will
-never monetize or sell your information, and this service and software will always stay free and open.**
+**Last updated:** June 15, 2026
 
-Neither the server nor the app record any personal information, or share any of the messages and topics with
-any outside service. All data is exclusively used to make the service function properly. The only external service
-I use is Firebase Cloud Messaging (FCM) service, which is required to provide instant Android notifications (see
-[FAQ](faq.md) for details). To avoid FCM altogether, download the F-Droid version.
+This privacy policy describes how ntfy ("we", "us", or "our") collects, uses, and handles your information
+when you use the ntfy.sh service, web app, and mobile applications (Android and iOS).
 
-For debugging purposes, the ntfy server may temporarily log request paths, remote IP addresses or even topics 
-or messages, though typically this is turned off.
+## Our commitment to privacy
+
+We love free software, and we're doing this because it's fun. We have no bad intentions, and **we will
+never monetize or sell your information**. The ntfy service and software will always stay free and open source.
+If you don't trust us or your messages are sensitive, you can [self-host your own ntfy server](install.md).
+
+## Information we collect
+
+### Account information (optional)
+
+If you create an account on ntfy.sh, we collect:
+
+- **Username** - A unique identifier you choose
+- **Password** - Stored as a secure bcrypt hash (we never store your plaintext password)
+- **Email address** - If you add an email address to your account for account recovery and password resets, for use
+  with the email notification feature, or if you subscribe to a paid plan (for billing purposes via Stripe). Email
+  addresses you add to your account are verified by sending a confirmation link.
+- **Phone number** - Only if you enable the phone call notification feature (verified via SMS/call)
+
+You can use ntfy without creating an account. Anonymous usage is fully supported.
+
+### Messages and notifications
+
+- **Message content** - Messages you publish are temporarily cached on our servers (default: 12 hours) to support 
+  message polling and to overcome client network disruptions. Messages are deleted after the cache duration expires.
+- **Attachments** - File attachments are temporarily stored (default: 3 hours) and then automatically deleted.
+- **Topic names** - The topic names you publish to or subscribe to are processed by our servers.
+
+### Technical information
+
+- **IP addresses** - Used for rate limiting to prevent abuse. May be temporarily logged for debugging purposes,
+  though this is typically turned off.
+- **Access tokens** - If you create access tokens, we store the token value, an optional label, last access time, 
+  and the IP address of the last access.
+- **Web push subscriptions** - If you enable browser notifications, we store your browser's push subscription 
+  endpoint to deliver notifications.
+
+### Billing information (paid plans only)
+
+If you subscribe to a paid plan, payment processing is handled by Stripe. We store:
+
+- Stripe customer ID
+- Subscription status and billing period
+
+We do not store your credit card numbers or payment details directly. These are handled entirely by Stripe.
+
+## Third-party services
+
+To provide the ntfy.sh service, we use the following third-party services:
+
+### Firebase Cloud Messaging (FCM)
+
+We use Google's Firebase Cloud Messaging to deliver push notifications to Android and iOS devices. When you 
+receive a notification through the mobile apps (Google Play or App Store versions):
+
+- Message metadata and content may be transmitted through Google's FCM infrastructure
+- Google's [privacy policy](https://policies.google.com/privacy) applies to their handling of this data
+
+**To avoid FCM entirely:** Download the [F-Droid version](https://f-droid.org/en/packages/io.heckel.ntfy/) of 
+the Android app and use a self-hosted server, or use the instant delivery feature with your own server.
+
+### Twilio (phone calls)
+
+If you use the phone call notification feature (`X-Call` header), we use Twilio to:
+
+- Make voice calls to your verified phone number
+- Send SMS or voice calls for phone number verification
+
+Your phone number is shared with Twilio to deliver these services. Twilio's 
+[privacy policy](https://www.twilio.com/legal/privacy) applies.
+
+### Amazon SES (email delivery)
+
+If you use the email notification feature (`X-Email` header), or when ntfy sends account-related emails (email 
+address verification and password reset links), we use Amazon Simple Email Service (SES) to deliver emails. The 
+recipient email address and message content are transmitted through Amazon's infrastructure. Amazon's 
+[privacy policy](https://aws.amazon.com/privacy/) applies.
+
+### Stripe (payments)
+
+If you subscribe to a paid plan, payments are processed by Stripe. Your payment information is handled directly 
+by Stripe and is subject to Stripe's [privacy policy](https://stripe.com/privacy).
+
+Note: We have explicitly disabled Stripe's telemetry features in our integration.
+
+### Web push providers
+
+If you enable browser notifications in the ntfy web app, push messages are delivered through your browser 
+vendor's push service:
+
+- Google (Chrome)
+- Mozilla (Firefox)
+- Apple (Safari)
+- Microsoft (Edge)
+
+Your browser's push subscription endpoint is shared with these providers to deliver notifications.
+
+## Mobile applications
+
+### Android app
+
+The Android app is available from two sources:
+
+- **Google Play Store** - Uses Firebase Cloud Messaging for push notifications. Firebase Analytics is 
+  **explicitly disabled** in our app.
+- **F-Droid** - Does not include any Google services or Firebase. Uses a foreground service to maintain 
+  a direct connection to the server.
+
+The Android app stores the following data locally on your device:
+
+- Subscribed topics and their settings
+- Cached notifications
+- User credentials (if you add a server with authentication)
+- Application logs (for debugging, stored locally only)
+
+### iOS app
+
+The iOS app uses Firebase Cloud Messaging (via Apple Push Notification service) to deliver notifications. 
+The app stores the following data locally on your device:
+
+- Subscribed topics
+- Cached notifications
+- User credentials (if configured)
+
+## Web application
+
+The ntfy web app is a static website that stores all data locally in your browser:
+
+- **IndexedDB** - Stores your subscriptions and cached notifications
+- **Local Storage** - Stores your preferences and session information
+
+No cookies are used for tracking. The web app does not have a backend beyond the ntfy API.
+
+## Data retention
+
+| Data type              | Retention period                                  |
+|------------------------|---------------------------------------------------|
+| Messages               | 12 hours (configurable by server operators)       |
+| Attachments            | 3 hours (configurable by server operators)        |
+| User accounts          | Until you delete your account                     |
+| Access tokens          | Until you revoke them or delete your account      |
+| Email addresses        | Until you remove them or delete your account      |
+| Phone numbers          | Until you remove them or delete your account      |
+| Web push subscriptions | 60 days of inactivity, then automatically removed |
+| Server logs            | Varies; debugging logs are typically temporary    |
+
+## Self-hosting
+
+If you prefer complete control over your data, you can [self-host your own ntfy server](install.md). 
+When self-hosting:
+
+- You control all data storage and retention
+- You can choose whether to use Firebase, Twilio, email delivery, or any other integrations
+- No data is shared with ntfy.sh or any third party (unless you configure those integrations)
+
+The server and all apps are fully open source:
+
+- Server: [github.com/binwiederhier/ntfy](https://github.com/binwiederhier/ntfy)
+- Android app: [github.com/binwiederhier/ntfy-android](https://github.com/binwiederhier/ntfy-android)
+- iOS app: [github.com/binwiederhier/ntfy-ios](https://github.com/binwiederhier/ntfy-ios)
+
+## Data security
+
+- All connections to ntfy.sh are encrypted using TLS/HTTPS
+- Passwords are hashed using bcrypt before storage
+- Access tokens are generated using cryptographically secure random values
+- The server does not log message content by default
+
+## Your rights
+
+You have the right to:
+
+- **Access** - View your account information and data
+- **Delete** - Delete your account and associated data via the web app
+- **Export** - Your messages are available via the API while cached
+
+To delete your account, use the account settings in the web app or contact us.

-### ntfy server v2.14.0
+## Current stable releases
+
+| Component        | Version | Release date  |
+|------------------|---------|---------------|
+| ntfy server      | v2.27.0 | Aug 4, 2026   |
+| ntfy Android app | v1.25.2 | July 23, 2026 |
+| ntfy iOS app     | v1.7.0  | May 30, 2026  |
+
+Please check out the release notes for [upcoming releases](#not-released-yet) below.
+
+### ntfy server v2.27.0
+Released August 4, 2026
+
+This release lets you sign in with your verified email address instead of your username, which should help if you ever
+signed up with an email and then forgot which username you picked. It also hardens the message templating engine against
+a few ways a small template could eat a lot of memory, and it drops the "experimental" label from
+[PostgreSQL support](config.md#postgresql), which has been running ntfy.sh for a while now.
+
+I also did a bunch of refactoring in, mostly in preparation for being able to cluster ntfy nodes and scale the service
+horizontally. It'll be a while until then, ... baby steps.
+
+**Security:**
+
+* Limit message templates (`Template: yes`) to 32 KB, limit `printf` widths and precisions to below 1000, and limit `indent`/`nindent` to 100 spaces, preventing excessive memory use from a single small template
+* Exclude secrets from the config hash served to the web app, preventing a rather theoretical information leak
+
+**Features:**
+
+* Allow logging in with your verified primary email address (in addition to your username), so a password reset no longer leaves you unable to sign in when you only remember the email you signed up with
+
+**Bug fixes + maintenance:**
+
+* Fix Twilio phone calls and phone number verifications failing silently when Twilio rejected the request, and move the Twilio integration into its own `twilio` package
+* Move the Prometheus metrics into a dedicated `metrics` package
+* Message cache databases from ntfy older than v1.10.0 (November 2021) can no longer be migrated; upgrade via an older ntfy version first, or delete the cache database
+* Fix `user_phone` table in the SQLite user database referencing a dropped table after the v2.14 schema migration; repaired automatically by a new migration
+
+## ntfy Android v1.25.2
+Released July 23, 2026
+
+This release makes the "connection lost" alert configurable and turns it off by default. Folks did not like it and many reached out
+or even gave ntfy bad reviews. I heard you! You can re-enable the alert in the advanced settings.
+
+The release also tries to be smarter about not retrying the connection at all if the app is in flight mode, or has no network. If there
+is no network, ntfy now keeps the foreground service alive and shows a "Waiting for network" notification, then resumes automatically
+once connectivity returns.
+
+Another change related to the networking is that we now force-reconnect when the connection is changed, e.g. during transitions
+from Wi-Fi to cellular network, or vice versa. That should allow for faster transitions during hand-overs.
+
+We also increase the client-side WebSocket ping interval from 1 minute to 3 minutes, which should slightly improve battery life,
+especially when paired with increaseing the server-side `keepalive-interval` in your self-hosted server.
+
+**Features:**
+
+* Add configurable "Alert when connection is lost" setting, turned off by default ([#1665](https://github.com/binwiederhier/ntfy/issues/1665), [#1662](https://github.com/binwiederhier/ntfy/issues/1662), [#1652](https://github.com/binwiederhier/ntfy/issues/1652), [#1655](https://github.com/binwiederhier/ntfy/issues/1655), thanks to [@tintamarre](https://github.com/tintamarre), [@sjozs](https://github.com/sjozs), [@TheRealOne78](https://github.com/TheRealOne78), and [@DAE51D](https://github.com/DAE51D) for reporting)
+* Handle "no network" gracefully: when the device is offline or in airplane mode, ntfy now stops retrying, suppresses the connection-lost alert, and keeps the foreground service alive with a "Waiting for network" notification, resuming instant delivery automatically when connectivity returns ([ntfy-android#165](https://github.com/binwiederhier/ntfy-android/pull/165), thanks to [@tintamarre](https://github.com/tintamarre) for the contribution, and [#1709](https://github.com/binwiederhier/ntfy/issues/1709), thanks to [@isaitgirl](https://github.com/isaitgirl) for reporting)
+* Improve battery life by increasing WebSocket client ping interval from 1 min to 3 min, and reconnect instantly on Wi-Fi/cellular/VPN transitions ([ntfy-android#113](https://github.com/binwiederhier/ntfy-android/pull/113), thanks to [@ftilde](https://github.com/ftilde) for the investigation)
+* Disable UnifiedPush components when UnifiedPush is disabled in settings ([ntfy-android#168](https://github.com/binwiederhier/ntfy-android/pull/168), thanks to [@p1gp1g](https://github.com/p1gp1g) for the contribution)
+
+**Bug fixes + maintenance:**
+
+* Fix the "connection lost" alert briefly disappearing and re-firing when roaming between networks (e.g. Wi-Fi to cellular), by no longer cancelling it during the transient no-network gap of a handover
+* Fix the "connection lost" alert repeatedly waking the screen while a server stayed unreachable, by no longer re-posting the alert once it is already showing
+* Fix the "connection lost" alert firing late, erratically, or not at all when a connection kept dropping (e.g. a flaky server) rather than being refused outright, by tracking how long the connection has been down independently of whether the drop warrants a UI error
+* Undo automatic phone number linking for numbers in message body ([ntfy-android#170](https://github.com/binwiederhier/ntfy-android/pull/170), thanks to [@acortelyou](https://github.com/acortelyou) for the contribution)
+* Fix subscription icons disappearing after a few days due to Android clearing cache ([#1322](https://github.com/binwiederhier/ntfy/issues/1322), thanks to [@mcanning](https://github.com/mcanning) for reporting)
+* Fix UnifiedPush `failed_reason` being sent as an enum instead of a string, which caused an exception in receiving apps that read it as a string extra ([ntfy-android#182](https://github.com/binwiederhier/ntfy-android/pull/182), thanks to [@p1gp1g](https://github.com/p1gp1g) for the contribution)
+
+### ntfy server v2.26.3
+Released July 20, 2026
+
+This is a hotfix release, useful pretty much only for ntfy.sh. It was adds the ability to track abusive IPs more
+efficiently, reducing the load on the IP banning services and preventing them from falling behind and leaving abusers
+unbanned for too long. It works by tracking HTTP errors, and writing out a ban file that fail2ban can read and ban
+offenders instantly. See [ban-feed](config.md#ban-feed) for details.
+
+**Features:**
+
+* Add an abuse ban-feed: when enabled via `ban-file`, ntfy tracks a weighted strike budget per visitor and appends abusive IPs to a file that fail2ban can tail and ban on sight (`ban-file`, `ban-window`, `ban-threshold`, `ban-weights`; see [ban-feed docs](config.md#ban-feed))
+
+### ntfy server v2.26.0
+Released July 9, 2026
+
+This release hardens **message templates**, which are now executed with a hard-capped execution timeout. This closes
+a denial-of-service hole.
+
+On the web app side, it adds configurable **date and time formats**, a smoother loading and page-transition experience,
+and a fix that strips unsafe URL protocols from rendered Markdown.
+
+**Security:**
+
+* Prevent a CPU denial of service via message templates (`Template: yes`) ([#1826](https://github.com/binwiederhier/ntfy/pull/1826), thanks to [@alanturing881](https://github.com/alanturing881), [@5ud0er](https://github.com/5ud0er) and [@jvoisin](https://github.com/jvoisin) for reporting)
+
+**Features:**
+
+* Web app: Add "Date format" and "Time format" settings (Settings -> Appearance), with ISO 8601, day/month/year (slash or dot) and month/day/year date options and a 12-/24-hour clock option, and base the default format on your browser/system locale rather than the selected display language. When logged in, both settings sync across devices via your account ([#1647](https://github.com/binwiederhier/ntfy/issues/1647), thanks to [@wsw70](https://github.com/wsw70) for reporting)
+
+**Bug fixes + maintenance:**
+
+* Web app: Smooth transitions and loading animation, remove flickering
+* Web app: `GET /account` now reads from the primary database instead of a read replica, so the account view no longer shows stale data right after a change when replicas lag behind
+* Docs: Document the third-party HelmForge Helm chart as a Kubernetes installation option ([#1727](https://github.com/binwiederhier/ntfy/issues/1727), thanks to [@mberlofa](https://github.com/mberlofa))
+* Web app: Strip unsafe URL protocols (`javascript:`, `data:`, ...) from links and images in Markdown-rendered messages, so they no longer trigger an uncaught "React has blocked a javascript: URL" error (thanks to [@jvoisin](https://github.com/jvoisin) for reporting)
+
+## ntfy server v2.25.0
+Released June 24, 2026
+
+This release adds **password reset** via email, and reworks email verification to use durable,
+link-based magic links (replacing the old in-memory 6-digit codes). Email stays optional at
+signup; a user can reset their password only once they have a verified "primary" (recovery)
+email.
+
+All of this work is probably not useful for self-hosters, but it hopefully will be useful for me,
+since I do have to reset accounts on a regular basis.
+
+**Security issues:**
+
+* Generate access tokens, IDs, and magic-link tokens with a cryptographically secure RNG (`crypto/rand`) instead of a clock-seeded PRNG
+
+**Features:**
+
+* Add password reset via emailed magic link, with a "Forgot password" link on the login page and a `ntfy user reset-pass` CLI command for admins
+* Rework email verification to use durable, single-use, expiring magic links instead of in-memory 6-digit codes, and add a "primary" email (used for account recovery and as the `X-Email: yes` target) with verified/unverified state in the account UI
+* You can now clear/read messages and delete messages with a GET request ([#1771](https://github.com/binwiederhier/ntfy/issues/1771), thanks to [@lemmi](https://github.com/lemmi) for reporting and to [@wunter8](https://github.com/wunter8) for implementing)
+* Add a reload button to the web app's action bar when running as an installed PWA, which clears the service worker caches and hard-refreshes the app ([#1281](https://github.com/binwiederhier/ntfy/issues/1281), thanks to [@leanza](https://github.com/leanza) for reporting)
+* Add a "Back to app" link to the web app's login, signup, and password-reset pages (alongside the existing links), which previously had no way back to the app
+
+**Bug fixes + maintenance:**
+
+* `X-Email: yes` (also `true`/`1`) now sends to your primary verified email regardless of the `smtp-sender-verify` setting (previously it was rejected unless verification was enabled); it requires being logged in with a verified address
+* Grant users full access to their own sync topic (`st_...`) so cross-device subscription sync works under `auth-default-access: deny-all` ([#733](https://github.com/binwiederhier/ntfy/issues/733), [#1795](https://github.com/binwiederhier/ntfy/pull/1795), thanks to [@lmorchard](https://github.com/lmorchard) for the contribution)
+* Support HTTP (non-TLS) S3-compatible endpoints by preserving the endpoint scheme, e.g. for a local MinIO instance ([#1794](https://github.com/binwiederhier/ntfy/pull/1794), [#1734](https://github.com/binwiederhier/ntfy/issues/1734), thanks to [@sskender](https://github.com/sskender) for the contribution, and [@Kernald](https://github.com/Kernald) for reporting)
+* Stop silently stripping spaces from passwords while typing in the web app's login, signup, and password-reset forms ([#1246](https://github.com/binwiederhier/ntfy/issues/1246), thanks to [@aldem](https://github.com/aldem) for reporting)
+* Update web app dependencies, including major-version upgrades to Vite (6 -> 8, now Rolldown-based), Material UI (5 -> 9), and Dexie (3 -> 4) ([#1800](https://github.com/binwiederhier/ntfy/pull/1800), [#1764](https://github.com/binwiederhier/ntfy/pull/1764), [#1767](https://github.com/binwiederhier/ntfy/pull/1767), [#1762](https://github.com/binwiederhier/ntfy/pull/1762), [#1766](https://github.com/binwiederhier/ntfy/pull/1766), [#1765](https://github.com/binwiederhier/ntfy/pull/1765), thanks Dependabot)
+* Play notification sounds in the web app even when the Notification API is unavailable, e.g. over plain HTTP or in browsers without notification support ([#1772](https://github.com/binwiederhier/ntfy/pull/1772), thanks to [@mitya12342](https://github.com/mitya12342) for the contribution)
+* Stop escaping `<`, `>`, and `&` as `\u003c`/`\u003e`/`\u0026` in JSON responses ([#1511](https://github.com/binwiederhier/ntfy/issues/1511), [#1512](https://github.com/binwiederhier/ntfy/pull/1512), thanks to [@wunter8](https://github.com/wunter8) for the contribution)
+* Fix the web app navbar not reflecting a topic reservation (lock icon, and "Reserve topic" -> "Change reservation"/"Remove reservation" menu) until a page reload, by persisting reservation and display-name changes onto already-subscribed topics during account sync
+* Reduce the web app's initial bundle size by ~300 KB (~50 KB gzipped) by lazy-loading the emoji picker dataset and the Markdown renderer, and by importing Material UI icons individually
+
+## ntfy server v2.24.0
+Released June 4, 2026
+
+The main feature for this release is an in-memory ACL cache (`auth-access-cache`) that can help bring down the read load
+on the production database. The topic authorization queries are consistently the highest ranking queries on the database,
+so this will help quite a bit. The current database load is quite low, but I'm expecting it to increase as more users join
+and use ntfy.
+
+**Security issues:**
+
+* Fix case-insensitive ACL topic matching on SQLite: an access control rule for `secret` no longer also matches a request for `SECRET`. SQLite's `LIKE` is case-insensitive for ASCII by default. PostgreSQL was unaffected. It's honestly incredible that this issue remained undetected for so long, especially while ntfy.sh was running on SQLite (it now runs on PostgreSQL).
+
+**Features:**
+
+* Add opt-in in-memory ACL cache (`auth-access-cache`) that serves topic authorization without a database round-trip; off by default, intended for high-volume servers
+* Add `ntfy --version` flag to the CLI ([#1722](https://github.com/binwiederhier/ntfy/issues/1722), [#1748](https://github.com/binwiederhier/ntfy/pull/1748), thanks to [@sskender](https://github.com/sskender) for the contribution, and [@Saucy9607](https://github.com/Saucy9607) for reporting)

+## ntfy iOS app v1.7.0
+Released May 30, 2026
+
+This release brings **image and attachment support** to the iOS app, finally closing one of the longest-standing iOS
+feature gaps. Images sent via the `Attach` header (or as a PUT body) are now previewed inline in the notification banner
+and inside the app, and other attachments can be downloaded, previewed via Quick Look, and shared from the notification
+row. There's also a new "Download attachments" setting to control auto-download by size.
+
+**Features:**
+
+* Show image previews in notifications and inline in the notification list, with tap-to-zoom Quick Look preview and share sheet ([ntfy-ios#40](https://github.com/binwiederhier/ntfy-ios/pull/40), [#276](https://github.com/binwiederhier/ntfy/issues/276), [#1226](https://github.com/binwiederhier/ntfy/issues/1226), thanks to [@am7590](https://github.com/am7590) for the contribution)
+* Download non-image attachments on demand with progress indication, persist them locally, and reuse files already fetched by the notification service extension ([ntfy-ios#40](https://github.com/binwiederhier/ntfy-ios/pull/40), thanks to [@am7590](https://github.com/am7590) for the contribution)

+
+**Bug fixes + maintenance:**
+
+* Improve background download reliability so attachments continue downloading when the app is suspended ([ntfy-ios#40](https://github.com/binwiederhier/ntfy-ios/pull/40), thanks to [@am7590](https://github.com/am7590) for the contribution)
+* Reorganize notification and subscription views into their own folders and split out `NotificationRowView` for readability ([ntfy-ios#40](https://github.com/binwiederhier/ntfy-ios/pull/40), thanks to [@am7590](https://github.com/am7590) for the contribution)
+
+## ntfy server v2.23.0
+Released May 17, 2026
+
+**Features:**
+
+* Add per-visitor rate limit on new topic creations (`visitor-topic-creation-limit-burst` / `visitor-topic-creation-limit-replenish`, defaults 100 burst / 1m replenish) to mitigate topic-enumeration / squatting attacks that inflate the in-memory topic map
+
+**Bug fixes + maintenance:**
+
+* Remove `stacktrace-js`, `stacktrace-gps`, `humanize-duration`, and `js-base64` from the web app to reduce dependency and security footprint
+* Restrict the publish dialog's local file preview to safe image types (png/jpg/gif/webp) to prevent same-origin script execution from blob URLs when previewing a crafted SVG ([GHSA-j8hr-p342-xrmh](https://github.com/binwiederhier/ntfy/security/advisories/GHSA-j8hr-p342-xrmh), thanks to [@Venukamatchi](https://github.com/Venukamatchi) for reporting)

+
+## ntfy iOS app v1.5.1

+
+## ntfy iOS app v1.4.1
+Released April 14, 2026
+
+This is the first iOS release in 3 years, focusing on stability fixes as per the [iOS improvement plan](https://github.com/binwiederhier/ntfy/issues/1680).
+
+**Bug fixes + maintenance:**
+
+* Fix crash when deleting notifications ([ntfy-ios#33](https://github.com/binwiederhier/ntfy-ios/pull/33), [#1642](https://github.com/binwiederhier/ntfy/issues/1642), [#377](https://github.com/binwiederhier/ntfy/issues/377), thanks to [@am7590](https://github.com/am7590) for the contribution)

+
+## ntfy server v2.21.0
+Released March 30, 2026
+
+This release adds the ability to verify email addresses using the `smtp-sender-verify` flag. This is a change that is
+required because ntfy.sh was used to send unsolicited emails and the AWS SES account was suspended. Going forward,
+ntfy.sh won't be able to send emails unless the email address was verified ahead of time.
+
+**Features:**
+
+* Add verified email recipients feature with `smtp-sender-verify` config flag, allowing server admins to require email
+  address verification before sending email notifications ([#1681](https://github.com/binwiederhier/ntfy/pull/1681))
+
+## ntfy server v2.20.1
+Released March 27, 2026
+
+This is a small bugfix release that only affects high volume S3 backends that struggle with HTTP/2.
+
+**Bug fixes + maintenance:**
+
+* [Attachments](config.md#attachments): Add `disable_http2=true` S3 URL option to work around HTTP/2 stream errors with DigitalOcean Spaces and other S3-compatible providers ([#1678](https://github.com/binwiederhier/ntfy/issues/1678)/[#1679](https://github.com/binwiederhier/ntfy/pull/1679))
+
+## ntfy server v2.20.0
+Released March 26, 2026
+
+This release is another step towards making it possible to help scale ntfy up and out 🔥! With this release, you can store
+attachments in an S3-compatible object store as an alterative to the directory. See [attachment store](config.md#attachments)
+for details.
+
+!!! warning
+    With this release, ntfy will take full control over the attachment directory or S3 bucket. Files/objects in the configured `attachment-cache-dir`
+    that match the message ID format (12 chars, matching `^[A-Za-z0-9]{12}$`), and have no entries in the message database will be deleted.
+    **Do not use a directory or S3 bucket as `attachment-cache-dir` that is also used for something else.**
+
+    This is a small behavioral change that was necessary because the old logic often left attachments behind and would not clean them
+    up. Unless you have re-used the attachment directory for anything else (which is hopefully never done), this should not affect
+    you at all.
+
+**Features:**
+
+* Add S3-compatible object storage as an alternative [attachment store](config.md#attachments) via `attachment-cache-dir` config option ([#1656](https://github.com/binwiederhier/ntfy/pull/1656)/[#1672](https://github.com/binwiederhier/ntfy/pull/1672))
+
+**Bug fixes + maintenance:**
+
+* Reject invalid e-mail addresses (e.g. multiple comma-separated recipients) with HTTP 400
+* Add OpenRC init service file ([#1650](https://github.com/binwiederhier/ntfy/pull/1650), thanks to [@ageru](https://github.com/ageru) for the contribution)
+
+## ntfy server v2.19.2
+Released March 16, 2026
+
+This is another small bugfix release for PostgreSQL, avoiding races between primary and read replica, as well as to
+further reduce primary load.
+
+**Bug fixes + maintenance:**
+
+* Fix race condition in web push subscription causing FK constraint violation when concurrent requests hit the same endpoint
+* Route authorization query to read-only database replica to reduce primary database load
+
+## ntfy server v2.19.1
+Released March 15, 2026
+
+This is a bugfix release to avoid PostgreSQL insert failures due to invalid UTF-8 messages. It also fixes `database-url`
+validation incorrectly rejecting `postgresql://` connection strings.
+
+**Bug fixes + maintenance:**
+
+* Fix invalid UTF-8 in HTTP headers (e.g. Latin-1 encoded text) causing PostgreSQL insert failures and dropping entire message batches
+* Fix `database-url` validation rejecting `postgresql://` connection strings ([#1657](https://github.com/binwiederhier/ntfy/issues/1657)/[#1658](https://github.com/binwiederhier/ntfy/pull/1658))
+
+## ntfy server v2.19.0
+Released March 15, 2026
+
+This is a fast-follow release that enables Postgres read replica support.
+
+To offload read-heavy queries from the primary database, you can optionally configure one or more read replicas
+using the `database-replica-urls` option. When configured, non-critical read-only queries (e.g. fetching messages, 
+checking access permissions, etc) are distributed across the replicas using round-robin, while all writes and
+correctness-critical reads continue to go to the primary. If a replica becomes unhealthy, ntfy automatically falls back
+to the primary until the replica recovers.
+
+**Features:**
+
+* Support [PostgreSQL read replicas](config.md#postgresql) for offloading non-critical read queries via `database-replica-urls` config option ([#1648](https://github.com/binwiederhier/ntfy/pull/1648))
+* Add interactive [config generator](config.md#config-generator) to the documentation to help create server configuration files ([#1654](https://github.com/binwiederhier/ntfy/pull/1654))
+
+**Bug fixes + maintenance:**
+
+* Web: Throttle notification sound in web app to play at most once every 2 seconds (similar to [#1550](https://github.com/binwiederhier/ntfy/issues/1550), thanks to [@jlaffaye](https://github.com/jlaffaye) for reporting)
+* Web: Add hover tooltips to icon buttons in web app account and preferences pages ([#1565](https://github.com/binwiederhier/ntfy/issues/1565), thanks to [@jermanuts](https://github.com/jermanuts) for reporting)
+
+## ntfy server v2.18.0
+Released March 7, 2026
+
+This is the biggest release I've ever done on the server. It's 14,997 added lines of code, and 10,202 lines removed, all from
+one [pull request](https://github.com/binwiederhier/ntfy/pull/1619) that adds [PostgreSQL support](config.md#postgresql).
+
+The code was written by Cursor and Claude, but reviewed and heavily tested over 2-3 weeks by me. I created comparison documents,
+went through all queries multiple times and reviewed the logic over and over again. I also did load tests and manual regression tests,
+which took lots of evenings.
+
+I'll not instantly switch ntfy.sh over. Instead, I'm kindly asking the community to test the Postgres support and report back to me
+if things are working (or not working). There is a [one-off migration tool](https://github.com/binwiederhier/ntfy/tree/main/tools/pgimport) (entirely written by AI) that you can use to migrate.
+
+**Features:**
+
+* Add experimental [PostgreSQL support](config.md#postgresql) as an alternative database backend (message cache, user manager, web push subscriptions) via `database-url` config option ([#1114](https://github.com/binwiederhier/ntfy/issues/1114)/[#1619](https://github.com/binwiederhier/ntfy/pull/1619), thanks to [@brettinternet](https://github.com/brettinternet) for reporting)
+
+**Bug fixes + maintenance:**
+
+* Preserve `<br>` line breaks in HTML-only emails received via SMTP ([#690](https://github.com/binwiederhier/ntfy/issues/690), [#1620](https://github.com/binwiederhier/ntfy/pull/1620), thanks to [@uzkikh](https://github.com/uzkikh) for the fix and to [@teastrainer](https://github.com/teastrainer) for reporting)
+
+## ntfy Android v1.24.0
+Released March 5, 2026
+
+This is a tiny release that will revert the "reconnecting ..." behavior of the foreground notification. Lots of people
+have complained about it, so I'm replacing it with a notification that shows up when the server connection has failed
+for >15 minutes, hoping that people will be less annoyed by that.
+
+**Features:**
+
+* Show notification when connection to server has been lost for 15+ minutes, with dismiss, snooze and never-show-again actions
+
+**Bug fixes + maintenance:**
+
+* Fix crash in settings when fragment is detached during backup/restore or log operations

+## ntfy Android app v1.20.0
+Released December 28, 2025
+
+This is the last pure maintenance release for now. It'll bring all dependencies and library version to the latest version,
+and fixes some crashes. I had to drop support for about 4,000 devices (only ~200 installations), because the libraries

+SDK version is 26 (Android 8, 2017).
+
+**Bug fixes + maintenance:**

+## Publishing messages
+_Supported on:_ :material-android:
+
+The Android app allows you to **publish messages directly from the app**, without needing to use curl or any other 
+tool. When enabled in the settings (Settings → General → Show message bar), a **message bar** appears at the bottom 
+of the topic view (it's enabled by default). You can type a message and tap the send button to publish it instantly.
+If the message bar is disabled, you can tap the floating action button (FAB) at the bottom right instead.
+
+For more options, tap the expand button next to the send button to open the full **publish dialog**. The dialog lets 
+you compose a full notification with all available options, including title, tags, priority, click URL, email 
+forwarding, delayed delivery, attachments, Markdown formatting, and phone calls.

+## Advanced settings
+
+### Custom headers
+_Supported on:_ :material-android:
+
+If your ntfy server is behind an **authenticated proxy or tunnel** (e.g., Cloudflare Access, Tailscale Funnel, or 
+a reverse proxy with basic auth), you can configure custom HTTP headers that will be sent with every request to 
+that server. You could set headers such as `Authorization`, `CF-Access-Client-Id`, or any other headers required by
+your setup. To add custom headers, go to **Settings → Advanced → Custom headers**.
+
+<div id="custom-headers-screenshots" class="screenshots">

+</div>
+
+!!! warning
+    If you have a user configured for a server, you cannot add an `Authorization` header for that server, as ntfy
+    sets this header automatically. Similarly, if you have a custom `Authorization` header, you cannot add a user
+    for that server.
+
+### Manage certificates
+_Supported on:_ :material-android:
+
+If you're running a self-hosted ntfy server with a **self-signed certificate** or need to use **mutual TLS (mTLS)** 
+for client authentication, you can manage certificates in the app settings.
+
+Go to **Settings → Advanced → Manage certificates** to:
+
+- **Add trusted certificates**: Import a server certificate (PEM format) to trust when connecting to your ntfy server.
+  This is useful for self-signed certificates that are not trusted by the Android system.
+- **Add client certificates**: Import a client certificate (PKCS#12 format) for mutual TLS authentication. This 
+  certificate will be presented to the server when connecting.
+
+When you subscribe to a topic on a server with an untrusted certificate, the app will show a security warning and 
+allow you to review and trust the certificate.

+| Error | Description |
+|-------|-------------|
+| Connection refused | The server may be down or the address may be incorrect |
+| WebSocket not supported | The server may not support WebSocket connections, or a proxy is blocking them |
+| Not authorized (401/403) | Username/password may be incorrect, or access credentials have expired |
+| Certificate not trusted | The server is using a self-signed certificate (see [Manage certificates](#manage-certificates)) |

+Your access to and use of the Service is conditioned on your acceptance of and compliance with these Terms. These 
+Terms apply to all visitors, users, and others who access or use the Service.
+
+**By accessing or using the Service, you agree to be bound by these Terms. If you disagree with any part of the 
+Terms, you may not access the Service.**
+
+## Service description
+
+ntfy (pronounced "notify") is a simple HTTP-based pub-sub notification service. It allows you to send push 
+notifications to your phone or desktop via scripts from any computer, using a REST API. The Service includes:
+
+- The ntfy.sh hosted server
+- The ntfy web application
+- The ntfy mobile applications (Android and iOS)
+- The ntfy command-line interface (CLI)
+
+The server software and mobile applications are open source and can be [self-hosted](install.md). These Terms 
+apply specifically to the ntfy.sh hosted service.
+
+## Subscriptions and billing
+
+### Free tier
+
+You may use the Service without creating an account or subscribing to a paid plan. Free usage is subject to 
+rate limits and other restrictions as described in our documentation.
+
+### Paid plans
+
+Some features of the Service are available only through paid subscription plans ("Subscriptions"). You will 
+be billed in advance on a recurring basis ("Billing Cycle"). Billing cycles are available on a monthly or 
+annual basis.
+
+At the end of each Billing Cycle, your Subscription will automatically renew under the same conditions unless 
+you cancel it or we cancel it. You may cancel your Subscription renewal through your account settings in the 
+web application.
+
+A valid payment method is required to process payment for your Subscription. You shall provide us with accurate 
+and complete billing information. By submitting such payment information, you authorize us to charge all 
+Subscription fees incurred through your account to your payment method.
+
+Payment processing is handled by Stripe. Your payment information is subject to Stripe's 
+[privacy policy](https://stripe.com/privacy) and [terms of service](https://stripe.com/legal).
+
+Should automatic billing fail to occur for any reason, we will retry the payment according to Stripe's retry 
+schedule. If payment continues to fail after multiple attempts, your Subscription will be canceled and your 
+account will revert to the free tier.
+
+### Fee changes
+
+We may, in our sole discretion and at any time, modify the Subscription fees for paid plans. Any fee change 
+will become effective at the end of the then-current Billing Cycle.
+
+We will provide you with reasonable prior notice of any change in Subscription fees to give you an opportunity 
+to cancel your Subscription before such change becomes effective.
+
+Your continued use of the Service after a fee change comes into effect constitutes your agreement to pay the 
+modified Subscription fee.
+
+## Refunds
+
+Refund requests for Subscriptions may be considered on a case-by-case basis and granted at the sole discretion 
+of ntfy LLC. To request a refund, please contact us at [billing@mail.ntfy.sh](mailto:billing@mail.ntfy.sh).
+
+## User accounts
+
+When you create an account with us, you must provide information that is accurate, complete, and current at 
+all times. Failure to do so constitutes a breach of the Terms, which may result in immediate termination of 
+your account.
+
+You are responsible for:
+
+- Safeguarding the password that you use to access the Service
+- Any activities or actions under your account, whether your password is with our Service or a third-party service
+- Keeping your account credentials confidential
+
+You agree not to disclose your password to any third party. You must notify us immediately upon becoming aware 
+of any breach of security or unauthorized use of your account.
+
+You represent that you are at least 18 years old, or that you are at least the minimum age required to form
+a binding contract in your jurisdiction, and have the legal authority to enter into these Terms.
+
+## Acceptable use
+
+You agree not to use the Service to:
+
+- Send spam, unsolicited messages, or messages to recipients who have not consented to receive them
+- Distribute malware, viruses, or any other malicious software
+- Transmit illegal content or content that violates the rights of others
+- Harass, abuse, or harm another person or group
+- Impersonate any person or entity, or falsely state or misrepresent your affiliation with a person or entity
+- Interfere with or disrupt the Service or servers or networks connected to the Service
+- Attempt to gain unauthorized access to the Service, other accounts, or computer systems
+- Use the Service for any illegal purpose or in violation of any applicable laws or regulations
+- Circumvent rate limits or other technical restrictions
+- Use the Service in a manner that could reasonably be expected to impose an unreasonable or disproportionately
+  large load on our infrastructure
+
+We reserve the right to investigate and take appropriate action against anyone who, in our sole discretion, 
+violates this provision, including removing content, terminating accounts, and reporting to law enforcement.
+
+### Topic names
+
+Topic names on ntfy.sh are public. If you use the Service without access controls, your topic name functions 
+as a password. You are responsible for choosing topic names that cannot be easily guessed. We are not responsible 
+for any unauthorized access to messages published to easily guessable topic names.
+
+For reserved topics and access control features, consider subscribing to a paid plan.
+
+## Intellectual property

+
+## Service availability
+
+The Service is provided on a "best effort" basis. We do not guarantee any specific uptime or availability.
+
+We strive to maintain high availability, but the Service may be interrupted for maintenance, updates, or 
+due to circumstances beyond our control. We will make reasonable efforts to notify users of planned 
+maintenance when possible.
+
+For applications requiring guaranteed uptime or specific service level agreements, we recommend 
+[self-hosting your own ntfy server](install.md).
+
+A [status page](https://ntfy.statuspage.io/) is available to check the current operational status of the Service.
+
+## Third-party services

+- **Stripe** - For payment processing
+
+Your use of these features is subject to the respective third-party terms and privacy policies. For more 
+details, see our [privacy policy](privacy.md).
+
+## Links to other websites
+
+Our Service may contain links to third-party websites or services that are not owned or controlled by us.
+
+We have no control over, and assume no responsibility for, the content, privacy policies, or practices of 
+any third-party websites or services. You acknowledge and agree that we shall not be responsible or liable, 
+directly or indirectly, for any damage or loss caused by or in connection with the use of any such content, 
+goods, or services available through any such websites or services.
+
+## Termination
+
+We may terminate or suspend your account immediately, without prior notice or liability, for any reason 
+whatsoever, including without limitation if you breach these Terms.
+
+Upon termination, your right to use the Service will immediately cease. If you wish to terminate your account, 
+you may do so through your account settings or by simply discontinuing use of the Service.
+
+Termination of your account will result in the deletion of your account data in accordance with our 
+[privacy policy](privacy.md).
+
+We may retain certain data as required to comply with legal obligations, resolve disputes, and enforce our
+agreements, as described in our privacy policy.
+
+## Limitation of liability
+
+In no event shall ntfy LLC, nor its owner, employees, partners, agents, suppliers, or affiliates, be liable 
+for any indirect, incidental, special, consequential, or punitive damages, including without limitation:
+
+- Loss of profits, data, use, goodwill, or other intangible losses
+- Damages resulting from your access to, use of, or inability to access or use the Service
+- Damages resulting from any conduct or content of any third party on the Service
+- Damages resulting from any content obtained from the Service
+- Damages resulting from unauthorized access, use, or alteration of your transmissions or content
+
+This limitation applies whether based on warranty, contract, tort (including negligence), or any other legal 
+theory, whether or not we have been informed of the possibility of such damage, and even if a remedy set 
+forth herein is found to have failed of its essential purpose.
+
+## Indemnification
+
+You agree to defend, indemnify, and hold harmless ntfy LLC and its owner, employees, partners, agents, suppliers,
+and affiliates from and against any claims, damages, obligations, losses, liabilities, costs, or debt, and
+expenses (including but not limited to attorney's fees) arising from:
+
+- Your use of and access to the Service
+- Your violation of any term of these Terms
+- Your violation of any applicable law or regulation
+- Your content, including any claim that your content infringes or misappropriates the rights of any third party
+
+## Disclaimer
+
+Your use of the Service is at your sole risk. The Service is provided on an "AS IS" and "AS AVAILABLE" basis, 
+without warranties of any kind, whether express or implied, including but not limited to implied warranties of 
+merchantability, fitness for a particular purpose, non-infringement, or course of performance.
+
+ntfy LLC does not warrant that:
+
+- The Service will function uninterrupted, secure, or available at any particular time or location
+- Any errors or defects will be corrected
+- The Service is free of viruses or other harmful components
+- The results of using the Service will meet your requirements
+- Messages will be delivered successfully or in a timely manner
+
+If your use case requires guaranteed message delivery, high availability, or handling of sensitive data, we 
+strongly recommend [self-hosting your own ntfy server](install.md) where you have full control over the 
+infrastructure and data.
+
+## Governing law
+
+These Terms shall be governed and construed in accordance with the laws of the State of Connecticut, United States,
+without regard to its conflict of law provisions.
+
+Any legal action or proceeding arising under these Terms shall be brought exclusively in the federal or state
+courts located in Connecticut, and the parties hereby consent to personal jurisdiction and venue therein.
+
+Our failure to enforce any right or provision of these Terms will not be considered a waiver of those rights. 
+If any provision of these Terms is held to be invalid or unenforceable by a court, the remaining provisions 
+of these Terms will remain in effect.
+
+These Terms constitute the entire agreement between us regarding our Service and supersede any prior agreements 
+we might have had regarding the Service.
+
+## Changes to these Terms
+
+We reserve the right, at our sole discretion, to modify or replace these Terms at any time. If a revision is 
+material, we will try to provide at least 30 days' notice prior to any new terms taking effect.
+
+What constitutes a material change will be determined at our sole discretion. Changes will be posted on this 
+page with an updated "Last updated" date. You may also review all changes in the 
+[Git history](https://github.com/binwiederhier/ntfy/commits/main/docs/terms.md).
+
+By continuing to access or use our Service after those revisions become effective, you agree to be bound by 
+the revised Terms. If you do not agree to the new Terms, please stop using the Service.

+
+If all of your topics are showing as "Reconnecting" and notifications are taking a long time (30+ minutes) to come in, or if you're only getting new pushes with a manual refresh, double-check your configuration:
+
+* If ntfy is behind a reverse proxy (such as Nginx):
+    * Make sure `behind-proxy` is enabled in ntfy's config.
+    * Make sure WebSockets are enabled in the reverse proxy config.
+* Make sure you have granted permission to access all of your topics, either to a logged-in user account or to `everyone`. All subscribed topics are joined into a single WebSocket/JSON request, so a single topic that receives `403 Forbidden` will prevent the entire request from going through.
+    * In particular, double-check that `everyone` has permission to write to `up*` and your user has permission to read `up*` if you are using UnifiedPush.
