Apps that keep every byte on your device.
No accounts. No cloud. No servers to hack. No data to sell.
“We don't collect data because we never built servers to receive it. The app cannot transmit your data even if we wanted it to — it has no network permissions.”
The app declares no network permissions in its manifest. It physically cannot connect to the internet.
All data encrypted on-device with keys stored in your device's secure enclave. Only you can access it.
We never built infrastructure to receive your data. There's nothing to hack, subpoena, or sell.
Privacy-critical components are open-sourced on GitHub for anyone to audit and verify.
In a world where personal data can be weaponized, we built features that go beyond privacy into active safety.
A secondary PIN opens a fake version of the app with empty or realistic-looking decoy data. No visual indicator reveals which mode is active. In jurisdictions where personal data could be used against you, plausible deniability matters.
Emergency data deletion with configurable triggers. Shake pattern, specific PIN, widget button. Immediate, irrecoverable. Speed is safety.
Disguise the app as a calculator, notes app, or generic utility. No one looking at your phone will know it's a private app.

We don’t collect data.
There’s nothing to collect.
OnlyOffline apps have no servers, no analytics, no crash reporting, no telemetry, and no network permissions. Your data lives on your device and nowhere else. This is the entirety of our privacy policy because there is nothing else to say.
