+## Database options
+ntfy uses a database for storing messages ([message cache](#message-cache)), users and [access control](#access-control), and [web push](#web-push) subscriptions.
+You can choose between **SQLite** and **PostgreSQL** as the database backend.
+
+### SQLite
+By default, ntfy uses SQLite with separate database files for each store. This is the simplest setup and requires
+no external dependencies:
+
+* `cache-file`: Database file for the [message cache](#message-cache).
+* `auth-file`: Database file for authentication and [access control](#access-control). If set, enables auth.
+* `web-push-file`: Database file for [web push](#web-push) subscriptions.
+
+### PostgreSQL (EXPERIMENTAL)
+As an alternative, you can configure ntfy to use PostgreSQL for **all** database-backed stores by setting the
+`database-url` option to a PostgreSQL connection string:
+
+```yaml
+database-url: "postgres://user:pass@host:5432/ntfy"
+```
+
+When `database-url` is set, ntfy will use PostgreSQL for the [message cache](#message-cache),
+[access control](#access-control), and [web push](#web-push) subscriptions instead of SQLite. The `cache-file`,
+`auth-file`, and `web-push-file` options **must not** be set in this case.
+
+Note that setting `database-url` implicitly enables authentication and access control (equivalent to setting
+`auth-file` with SQLite). The default access is `read-write`, so anonymous users can still read and write to all
+topics. To restrict access, set `auth-default-access` to `deny-all` (see [access control](#access-control)).
+
+You can also set this via the environment variable `NTFY_DATABASE_URL` or the command line flag `--database-url`.
+
+The database URL supports the standard [PostgreSQL connection parameters](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS)
+as query parameters, such as `sslmode`, `connect_timeout`, `sslcert`, `sslkey`, `sslrootcert`, and `application_name`.
+See the [pgx driver documentation](https://pkg.go.dev/github.com/jackc/pgx/v5) for the full list of supported parameters.
+
+In addition, ntfy supports the following custom query parameters to tune the connection pool:
+
+| Parameter                 | Default | Description                                                                      |
+|---------------------------|---------|----------------------------------------------------------------------------------|

+| `pool_max_idle_conns`     | -       | Maximum number of idle connections in the pool                                   |
+| `pool_conn_max_lifetime`  | -       | Maximum amount of time a connection may be reused (Go duration, e.g. `5m`, `1h`) |
+| `pool_conn_max_idle_time` | -       | Maximum amount of time a connection may be idle (Go duration, e.g. `30s`, `5m`)  |
+
+Example:
+
+```yaml
+database-url: "postgres://user:pass@host:5432/ntfy?sslmode=require&pool_max_conns=50&pool_conn_max_idle_time=5m"
+```
+
 ## Message cache
 If desired, ntfy can temporarily keep notifications in an in-memory or an on-disk cache. Caching messages for a short period
 of time is important to allow [phones](subscribe/phone.md) and other devices with brittle Internet connections to be able to retrieve
 notifications that they may have missed. 
 
 By default, ntfy keeps messages **in-memory for 12 hours**, which means that **cached messages do not survive an application
-restart**. You can override this behavior using the following config settings:

 By default, the ntfy server is open for everyone, meaning **everyone can read and write to any topic** (this is how

+## 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.

+_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**.

+
+### 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.

+  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.

+# Terms of Service
+
+**Last updated:** January 26, 2026
+
+Please read these Terms of Service ("Terms") carefully before using the ntfy.sh website and service (the "Service") 
+operated by ntfy LLC ("us", "we", or "our").
+
+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

+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

+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.
+

+- 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.

+agreements, as described in our privacy policy.
+

+# pgimport
+
+Migrates ntfy data from SQLite to PostgreSQL.
+
+## Build
+
+```bash
+go build -o pgimport ./tools/pgimport/
+```
+
+## Usage
+
+```bash
+# Using CLI flags
+pgimport \
+  --database-url "postgres://user:pass@host:5432/ntfy?sslmode=require" \
+  --cache-file /var/cache/ntfy/cache.db \
+  --auth-file /var/lib/ntfy/user.db \
+  --web-push-file /var/lib/ntfy/webpush.db
+
+# Using server.yml (flags override config values)
+pgimport --config /etc/ntfy/server.yml
+```
+
+## Prerequisites
+
+- PostgreSQL schema must already be set up (run ntfy with `database-url` once)
+- ntfy must not be running during the import
+- All three SQLite files are optional; only the ones specified will be imported
+
+## Notes
+
+- The tool is idempotent and safe to re-run
+- After importing, row counts and content are verified against the SQLite sources
+- Invalid UTF-8 in messages is replaced with the Unicode replacement character
