About this app

[Instant privacy at your fingertips. No more awkward glances.]

Do you ever feel uncomfortable with people peeking at your screen on the train or in public? Do you need to hide sensitive emails or private messages from wandering eyes?

"Screen-Filter" is a high-performance privacy tool designed to keep your information safe.

■ Quick-Launch from Notification Panel
Add a button to your Android Quick Settings panel. Toggle the filter ON/OFF with a single tap, right over any app, without needing to return to the home screen.

■ 8 Visual Patterns to Block Prying Eyes
It’s more than just a color tint. Our filter uses patterns like dots, stripes, and grids to break up text and images, making it nearly impossible for others to read your screen from the side.

■ Powerful Color Contrast Protection
Layer a "White" filter for Dark Mode or a "Black" filter for Light Mode. By using the complementary color to your background, you can dramatically reduce visibility to onlookers.

■ Trusted & Secure

Ad-Free: No annoying ads to interrupt your experience.

100% Offline: We do not request internet permissions. Your private data and screen contents never leave your device.

■ Recommended For:
・Commuters on trains or buses.
・Professionals handling sensitive information in cafes or at work.
・Anyone who values privacy while using their phone in public.

Protect your privacy more smartly.
A small investment for peace of mind, anywhere you go.
