Accessibility Service API & Overlay Disclosure
AppLock: Fingerprint & PIN utilizes the Accessibility Service API and the "Display Over Other Apps" (Overlay) permission to ensure your security and privacy:
Accessibility Service: This permission is required exclusively to detect when a protected application is launched. This allows AppLock to identify the app opening and immediately trigger the lock screen.
Overlay Permission: This permission allows the lock screen to be displayed on top of the application being protected. This ensures the app's content remains hidden until the correct password or pattern is entered.
Important: We do not collect, store, or share any personal data, passwords, or usage information through these permissions. Their use is strictly limited to the locking functions requested by the user.
