Launch
The first release
- Fully offline by design. No account, no sync, no server; the secret never leaves the device and no copy is kept.
- Open-source core. The cryptographic core published on GitHub under Apache-2.0: constant-time Shamir Secret Sharing over GF(2^8) with no external dependencies.
- No tracking. No ads, no analytics, no in-app purchases, and no permissions the app does not need.
Per-build notes appear on the App Store listing.
