Enhanced EQ – Equalizer & Bass

ACCESSIBILITY SERVICE — WHY ENHANCED EQ ASKS FOR IT
The Per-App Profiles feature uses Android's Accessibility Service to detect which app is currently in the foreground so it can auto-apply the EQ profile you assigned to that app.

What it reads:
• Only the foreground app's package name (e.g. "com.spotify.music").

What it does NOT read:
• No audio is recorded, stored, or transmitted.
• No screen content, on-screen text, keystrokes, or passwords are accessed.
• No personal data is collected, shared, or sold.

The package name is processed locally on your device only. The service is opt-in — enable it from the Per-App Profiles screen, and disable it anytime in Android Settings → Accessibility to stop Per-App Profiles instantly without affecting any other feature.

Enhanced EQ runs as a persistent foreground service so your sound stays tuned no matter what app you're in.
