## 🔒 Accessibility Service

Luma uses Android's AccessibilityService only to detect which app is currently open so it can automatically apply the display settings you have configured.

AccessibilityService is used exclusively for:
• Per-app brightness
• Automatic display profile switching
• App-based display automation

Luma does **not** use AccessibilityService to read, collect, store, or share the contents of your screen, typed text, passwords, or personal information. All processing related to these features occurs locally on your device.

Accessibility permission is optional. If you choose not to enable it, you can still use Luma's manual display controls, display profiles, widgets, and time-based automation.
