🔍 Accessibility Service Usage
BrightLock uses the Android Accessibility Service to detect which app is currently visible on screen only for enabling app-specific brightness rules.

Why this is needed:
- Android does not provide any other reliable way to know which app is in the foreground.
- This allows BrightLock to apply your chosen brightness when an app opens and restore it when you leave the app.

What the Accessibility Service does:
- Detects the foreground app name
- Triggers brightness rules you configured for that app

What it does NOT do:
❌ Does NOT read screen content
❌ Does NOT record keystrokes
❌ Does NOT collect personal data
❌ Does NOT monitor your activity outside this purpose

The Accessibility Service is used strictly for this feature, runs locally on your device, and can be turned off anytime from system settings.
