| Release info | New Release on Oct 06, 2026 |
|---|---|
| Release notes | Rewritten in Kotlin: same notes and vaults, an 8 MB app. New: app lock (PIN, optional biometrics); German, Italian, Spanish. Security audit fixes: closing a vault clears the open note; deleted text leaves the search index; copies from a vault use the protected clipboard. Before Android 9, no new PIN vault. One-way update: 2.x cannot be reinstalled over it, and uninstalling erases your notes. F-Droid and GitHub copies do not update each other. |
