Accessibility Service Usage App Lock – Fingerprint Lock uses the AccessibilityService API to protect your privacy and secure your apps. We use this API ONLY to detect when a protected app is launched or closed. This allows us to provide a seamless locking experience by showing the password/biometric overlay precisely when you open a locked app.

App Lock does NOT use the AccessibilityService API to:

Change user settings without permission.
Work around Android built-in privacy controls and notifications.
Change the user interface in a deceptive way.
Record audio or collect any private data.
The Accessibility Service is essential for the core functionality of App Lock. We do not collect, store, or share any personal or sensitive user data through the Accessibility API. All processing happens locally on your device.
