This screen filter will let you cover most of your screen except a small cutout.
You can move and resize the mask, so you yourself can still see everything.
The rectangle is as wide as the screen so it's perfect for texting. The small circle is ideal for even more secret things.
🌑 The new "OLED" mode turns the screen completely black while keeping the device on. It's perfect for listening to music without stopping the app.
Protect your privacy from:
🔒 Strangers on the bus, train, subway or plane
🔒 Nosy friends and family
🔒 Strict bosses and colleagues
🔒 Shoulder surfing and other social engineering techniques
🛡️ Hiding "not safe for work" (NSFW) content.
🛡️ Logging in securely with your PINs, passwords or passcodes.
🛡️ Dimming the screen even further than normally possible.
This screen guard can hide your confidential data from strangers looking over your shoulder.
It hides the background with a shade to keep your sensitive content private from observers. It works with WhatsApp, Telegram, Signal or any other chatting app.
It's very simple to use:
The screen filter will stay active even when you close the app.
Drag the red dot to move the hole. Double tap it to make it bigger.
You can also change the opacity and shape.
The overlay can also be started from the home screen with a shortcut. Or even from the quick settings tile.
All functions can be used for free but there is a short ad for one of my other apps. I purposefully didn't implement normal ads from the big ad networks to protect your user data. You can remove the ad with a cheap in-app-purchase.
No additional downloads, no service that runs all the time! :-)
