Apps that make the world safer.
We build privacy-first tools that protect people. Everything we ship runs on your device, so there is no cloud, no tracking, and nothing collected.
One app at a time, properly.
Explicit content, covered before it lands.
On-device AI watches the screen, not the network, and covers explicit imagery the moment it appears, in any app, on any connection.
- Works across every app, system-wide
- Fully offline: nothing is ever uploaded
- A PIN is needed to switch it off
- Adjustable sensitivity and fingerprint unlock
Most software is paid for by watching you. We build the other way: if it can run on your phone, it never leaves it.

On-device by default
If a feature can run locally, it runs locally. Sending your data to a server is a last resort, not the default architecture.
Collect nothing
No analytics SDKs, no advertising identifiers, no behavioural telemetry. The safest way to protect data is never to hold it.
Free where it matters
Tools that protect children and vulnerable people should not sit behind a paywall. ScreenBlock is free, with no account required.
Say what the software actually does
No inflated claims about what an app can protect you from. Where a tool has limits, we write them down.
Working on something aligned?
Press enquiries, partnership ideas, bug reports, or feedback on an app. It all reaches the same inbox, and we read every message.
