About this app

App Lock is a highly efficient and intelligent screen management tool that helps you lock the launch and opening of any application, and it's completely free.

Main Features:

- Numeric Password: Supports multiple numeric password length settings.

- Detection Methods: Supports monitoring application activity status through accessibility services, user usage, etc.

- Application Detection: It will query information for all applications in the system, and you can set on/off switches to lock applications.

- Easy to Use: Simple interface, intuitive operation, easy to learn.

- No Root Permission Required: All functions require no root permission, safe and reliable.

Important Note:

1. Why use the AccessibilityService API?

A: This program uses the AccessibilityService API to implement the foreground/background switching state of applications, ensuring that the screen lock function is accurately triggered in the specified application scenarios. It will not prevent users from disabling or uninstalling any applications or services, requesting remote call recording, performing operations or decisions, etc., and strictly adheres to the Google Play Accessibility Services guidelines.

2. How to enable the AccessibilityService API?

A: AccessibilityService API permissions must be manually enabled by the user in system settings. The application will not automatically request or forcibly enable this permission, and will clearly guide the user on the permission request page.

3. Will we collect privacy data?

A: We will not collect, store, or upload any user privacy information through the AccessibilityService API interface. It only runs locally on the device. Users can disable accessibility permissions for this application at any time in "System Settings > Accessibility". Disabling it only affects the use of the lock screen function and does not affect the operation of the application's basic functions.
