ScreenBlock (Screen Block) — real-time explicit content filter for your whole device.

ScreenBlock detects and instantly blurs explicit (NSFW) content across any app on your screen — browsers, social media, chat apps, galleries — all processed entirely on your device. Nothing you view ever leaves your phone.

WHO SCREENBLOCK IS FOR

Parents — Add a safety layer that filters inappropriate content before your child sees it, across every app, not just one browser.

Professionals & workplaces — Keep your screen safe and appropriate in the office, on public transport, or anywhere content might appear unexpectedly.

Anyone building healthier habits — If you're working to cut explicit content out of your life, Screen Block adds a real-time barrier and an accountability layer to support your goal.

HOW IT WORKS

• Scans your screen in real time using on-device AI — no internet upload, no cloud servers.
• Instantly masks detected explicit imagery with an overlay.
• Optional password protection so the filter can't be disabled without your PIN.
• Runs quietly in the background across all apps.

YOUR PRIVACY COMES FIRST

All detection happens locally on your device. ScreenBlock does not upload, store, or share the content on your screen. Ever.

PERMISSIONS SCREENBLOCK USES

• Display over other apps — to show the blur overlay above other apps.
• Media projection / screen access — to scan the current screen for explicit content in real time.
• Notifications — to keep the protection service running reliably.

ScreenBlock only uses these permissions to provide its filtering feature. It does not track your activity or collect personal data.

Take control of what appears on your screen — for your family, your workplace, and yourself.
