♿ Accessibility Service Usage

App Locker uses the Android AccessibilityService API to detect when a selected application is opened. This allows the app to display a secure lock screen and protect selected apps with a password or fingerprint.

Accessibility permission is required only for app locking functionality.

App Locker does NOT collect, store, or share personal data, messages, or sensitive information using this service.

The accessibility service is used only to monitor app launch events so that the lock screen can be displayed when a protected app is opened.

Users can disable this permission anytime from the device Accessibility settings.
