> AISixteen is an independent developer of small, fast, private apps for iPhone, iPad and Mac. Every app runs entirely on-device: no accounts, no tracking, and no data ever leaves the user's device.

## About
- All apps work offline and require no account or sign-up.
- No personal data is collected, stored, or transmitted by any app.
