About this app

Tired of pressing the physical power button to lock your screen every time? Is your power button broken? Worried about damaging the buttons with prolonged use?

Blackout provides the most elegant and efficient solution!

This is an ultra-lightweight utility app designed to enhance your Android user experience. It has only one core goal: allowing you to lock your device screen with a single tap through the Quick Settings panel.

【Core Features】

-------------------------------------------------
■ Quick Settings Integration: The "Lock Screen" tile is directly added to your phone's pull-down Quick Settings panel, alongside system functions like Wi-Fi and Bluetooth.

■ One-Touch Lock: No matter which app you're using, simply swipe down to open Quick Settings, tap the "Blackout" tile, and the screen will lock instantly.

■ Protect Hardware Buttons: Reduces reliance on and wear and tear on the physical power button, effectively extending its lifespan.

■ Minimalist Design: No complicated settings, no background services, no ads. Installation, licensing, and use—it's that simple!

【How to Use】

---------------------------------
1. Install "Blackout".

2. Scroll down and edit your quick settings panel.

3. Locate the "Blackout" tile and drag it to your desired location.

4. Click the tile. The first time you use it, the app will guide you to enable the necessary "Device Administrator" permissions.

5. Done! Enjoy the convenience of one-click screen locking!

【Permissions and Privacy Policy】

--------------------------------------------- To enable the screen locking function, the Android system requires such applications to obtain "Device Administrator" permissions.

We solemnly promise you:

● "Blackout" will only use this permission to execute the single command "Lock Screen".

● This application **will not** collect, store, read, or transmit any of your personal data or device information.

● Your privacy is our top priority. We are a tool, not a tracker.

If you have any questions about permissions or would like to provide feedback, please feel free to contact us through our developer contact information.
