# Critical Alerts

An entitlement that permits an app to receive critical alert notifications.

## Discussion

If your app has this entitlement, then it can request <doc://com.apple.documentation/documentation/UserNotifications/UNAuthorizationOptions/criticalAlert> authorization to receive push notifications that cause the system to play a sound even when the app is locked, muted, or a person uses Do Not Disturb focus.
Your app can specify a custom sound and volume for critical alerts.

To request this entitlement for your app, [fill out the request form](https://developer.apple.com/contact/request/notifications-critical-alerts-entitlement/).
