## Web Push notifications
## Web Push
[Web Push](https://developer.mozilla.org/en-US/docs/Web/API/Push_API) ([RFC8030](https://datatracker.ietf.org/doc/html/rfc8030))

The `web-push-subscriptions-file` is used to store the push subscriptions. Subscriptions do not ever expire automatically, unless the push
gateway returns an error (e.g. 410 Gone when a user has unsubscribed).
The `web-push-subscriptions-file` is used to store the push subscriptions. Unused subscriptions will send out a warning after 7 days,
and will automatically expire after 9 days (not configurable). If the gateway returns an error (e.g. 410 Gone when a user has unsubscribed),
subscriptions are also removed automatically.
The web app refreshes subscriptions on start and regularly on an interval, but this file should be persisted across restarts. If the subscription
file is deleted or lost, any web apps that aren't open will not receive new web push notifications until you open then.

# Using the web app as an installed web app
While ntfy doesn't have a native desktop app, it is built as a [progressive web app](https://developer.mozilla.org/en-US/docs/Web/Progressive_web_apps) (PWA)
and thus can be installed on both desktop and mobile. This gives it its own launcher (e.g. shortcut on Windows, app on
macOS, launcher shortcut on Linux) own window, push notifications, and an app badge with the unread notification count.
and thus can be installed on both desktop and mobile devices. This gives it its own launcher (e.g. shortcut on Windows, app on
macOS, launcher shortcut on Linux), own window, push notifications, and an app badge with the unread notification count.
To install and register the web app in your operating system, click the "install app" icon in your browser (usually next to the
address bar). To receive background notifications, **either the browser or the installed web app must be open**.
