Brightness Control - Per App

Brightness Control, app by app.

Most phones give you one global brightness slider. LuxKeeper gives you per-app control: set exactly how bright or dim each app should be — and it's applied automatically the moment that app comes to the front. Leave the app and your normal brightness returns.

Dim a reading or e-book app for comfortable evening use, keep a maps or video app bright, turn a chat app down low, and leave everything else on your usual brightness — all at the same time.

WHAT YOU CAN DO
• Set a custom brightness level for any installed app.
• Rules apply instantly when you open a ruled app.
• Your usual brightness comes back when you leave.
• Works whether your system auto-brightness is on or off.

WHY LUXKEEPER
• True per-app brightness — every app at the level you want.
• No accessibility service required.
• Doesn't change your global system brightness setting.
• No ads. No tracking. No account. Everything stays on your device.

PERMISSIONS (plainly explained)
• Usage access — to detect which app is in front, so the right rule is applied.
• Display over other apps — to set the brightness for the current app.
• Optional but recommended: allow background running / auto-launch. Some phones (Honor, Xiaomi, Oppo and similar) aggressively close background apps; allowing LuxKeeper to run keeps your rules reliable. There's a one-tap button in the app that takes you straight to the right setting.

PREMIUM
• A one-time purchase unlocks unlimited rules. No subscription, ever.

LuxKeeper does one thing well: it puts you in control of screen brightness, app by app.
