ScreenBlock uses on-device AI to detect and mask NSFW content in real time — across every app, every browser, every screen.
Scans your screen continuously and masks explicit content the instant it appears — no delay, no manual action needed.
Works across every app — browsers, social media, video players, photo galleries. Not limited to one site or app.
Set a PIN so protection cannot be disabled without your code. Ideal for parental controls on shared devices.
All AI processing happens on your device. Your screen content is never uploaded, stored, or shared with anyone.
Runs as a foreground service in the background. Turn it on once and it stays active until you choose to stop it.
The AI model runs entirely offline. ScreenBlock works without a network connection — no cloud dependency at all.
Download ScreenBlock from Google Play and grant the necessary permissions.
Choose a PIN to lock the controls so only you can stop or configure protection.
Tap Start — ScreenBlock runs silently in the background from this point on.
Explicit content is masked the instant it appears, in any app, automatically.
