Screen Guard : Privacy Display

Ever feel like the person sitting next to you on the bus or subway is staring right at your phone?

Privacy Display is a simple screen shade that puts an adjustable filter over your display, making it much harder for people nearby to shoulder-surf your messages, passwords, or banking apps.

Instead of buying a physical privacy glass protector that permanently dims your screen and ruins viewing angles at home, you can just turn this app on whenever you're in a crowded spot and shut it off the second you're alone.
Main Features:
Adjustable Privacy Filter: Change the tint and opacity with a simple slider. Make it pitch black or just slightly shaded—whatever feels comfortable for you.

One-Tap Quick Toggle: Turn the filter on or off instantly.
Night Screen Dimmer: Works great as an extra brightness dimmer at night when your phone’s built-in lowest brightness is still too harsh in a dark room.
Best Times to Use It:
Texting friends on crowded buses, trains, or in line at the store.
Typing in passwords, credit card info, or checking bank balances in public.
Browsing social media or reading work emails around nosey coworkers.
Why the "Display over other apps" permission is needed:
To draw the dark privacy shade on top of your other apps, Android requires the screen overlay permission. This app does not record, read, or track anything on your screen—it simply puts a digital tinted layer on top to keep your screen to yourself.
