Cyber Phone

Ariadne Cyber

About this app

A privacy-first replacement for your default Phone and SMS apps, hardened with mesh networking that keeps you connected when the grid doesn't.
Modern messaging apps are bloated with trackers, analytics, and cloud dependencies. Cyber Phone strips it back: no Google Play Services, no analytics, no cloud lock-in. Just a powerful dialer and messenger built for users who own their data.
