Engineering for the greater good
Apps that make the world safer
Truth Ocean is an independent studio building privacy-first tools that protect people. Everything we ship runs on your device — no cloud, no tracking, nothing collected.
Our mission
Solutions engineered for
people, not profit
We believe technology should serve the person using it. Every product we build is designed to solve a real problem, protect real people, and leave the world a little better than we found it — without harvesting anything along the way.
Safety first
We build tools that protect — from harmful content, from bad actors, from the things that shouldn't reach your screen in the first place.
Privacy by design
Everything runs on your device. No cloud processing, no analytics, no accounts. Your data belongs to you and never reaches us.
Always on
Protection that works quietly in the background, so it keeps doing its job on the days you forget it is there.
Real-time explicit content filtering for Android
ScreenBlock uses on-device AI to detect and cover explicit imagery the moment it appears — in any app, on any network, with no internet connection required.
- Blocks explicit content in real time
- Works across every app, system-wide
- Fully offline — nothing ever uploaded
- PIN-locked so only you can disable it
How we build
Four commitments we don't trade away
On-device by default
If a feature can run locally, it runs locally. We treat sending your data to a server as a last resort, not a default architecture.
Collect nothing
No analytics SDKs, no advertising identifiers, no behavioural telemetry. The safest way to protect data is to never 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.
