Why Device Administrator Permission?

Android requires Device Administrator permission to allow Screen Off Timer to automatically lock and turn off your screen when the timer expires. This permission provides a secure and reliable way for the app to lock your device without requiring access to your screen content or other personal information.

This permission is used strictly for locking your device when the timer expires. We do not access, monitor, collect, or store any personal data or screen content.

Why Do Not Disturb Access?

Android requires your permission to allow Screen Off Timer to enable Do Not Disturb automatically. This access is used only when you choose the Do Not Disturb option and can be revoked at any time from your device settings.
