ScreenBlock: Explicit Filter

ScreenBlock — real-time explicit content filter and parental control for your whole device.

ScreenBlock detects and instantly blurs explicit (NSFW) content across every app on your screen — browsers, social media, chat apps, galleries — processed entirely on your device. Nothing you view ever leaves your phone. No internet connection needed.

WHO SCREENBLOCK IS FOR

Parents & families — A system-wide parental control that filters explicit content before your child sees it, across every app, not just one browser. PIN-lock the settings so children cannot disable protection.

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, ScreenBlock 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, works fully offline.

• Instantly masks detected explicit imagery with a protective overlay.

• PIN-locked controls so the filter cannot be disabled without your code.

• Runs quietly in the background across all apps — set it once and forget it.

YOUR PRIVACY COMES FIRST

All detection happens locally on your device. ScreenBlock does not upload, store, or share anything on your screen. Ever. No analytics. No tracking. Zero data collection.

PERMISSIONS SCREENBLOCK USES

• Display over other apps — to show the protective overlay above other apps.

• Media Projection / screen access — to scan the screen for explicit content in real time. Content is processed on-device only and never stored or transmitted.

• Notifications — to keep the protection service running reliably in the background.

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.
