App Lock – Secure Your Apps & Privacy

App Lock is a powerful privacy protection tool that helps you secure apps and personal data with password, fingerprint, pattern, or knock code. It prevents unauthorized access and keeps sensitive information on your phone private.

To provide its core security features, the app may use certain Android permissions and system services, including the AccessibilityService API to detect when protected apps are opened so they can be locked instantly. The app may also request CAMERA permission for features such as intruder selfie, and READ_MEDIA_IMAGES and READ_MEDIA_VIDEO permissions to allow you to select and secure photos or videos in the private vault.

With App Lock, you can lock apps, protect media files, and safeguard sensitive content in one simple solution.
