## Description

Lock Screen is a lightweight, accessible utility designed to help users lock their screen easily without needing to interact with physical hardware buttons.

✓ Extending phone hardware lifespan by offering an accessible on-screen locking method.

Prominent Disclosure & Accessibility API Usage:  
This app uses the AccessibilityService API solely to perform the system-level action of turning off and locking the screen.

• Data Privacy: This app DOES NOT collect, store, or share any personal or sensitive user data via the AccessibilityService API. The API is used strictly to execute the screen-lock action.  
  
Permissions Used:  
• Accessibility Service: Used exclusively to perform the screen lock action.  
• Device Administrator Permission: Used on older Android versions as an alternative method to lock the device screen.
