🔍 Accessibility Service Usage
BrightLock uses the Android Accessibility Service only to detect which app is currently visible for the App-Specific Brightness feature.

Why this is needed:
Android does not provide another reliable way to detect the foreground app.
This allows BrightLock to automatically apply and restore your chosen brightness settings.

What the Accessibility Service does:
- Detects the foreground app
- Triggers brightness rules you've configured

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

The Accessibility Service is used strictly for this feature, runs entirely on your device, and can be disabled anytime from Android Settings.

👥 Who is BrightLock For?
- Parents who want safe screen brightness for children
- Students and readers who need consistent brightness
- Gamers and media lovers who prefer custom brightness per app
- Night-time users looking to reduce eye strain
- Anyone who wants smarter brightness control and better privacy
