Local-only OpenPGP suite. Manage multiple keypairs, keep a roster of contacts' public keys, encrypt/decrypt & sign/verify both text and files, exchange keys by paste / file / QR. Built on Bouncy Castle — no network, no keyserver, no Web Key Directory, no auto-sync. 8.5 MB. Multiple RSA-3072 keypairs — generate as many as you want, pick which one is active. Each is passphrase-protected on disk, stored only in app-private internal storage Import existing OpenPGP secret keys from any standards-conformant tool (gpg, OpenKeychain, Sequoia, etc.) — pick a .asc / .key file, it joins your vault as a selectable identity Local contact roster for imported public keys: paste, file pick, or QR scan Encrypt & decrypt for both text and files (streaming for large files, recipient picker for encrypt) Sign & verify for both text and files (detached OpenPGP signatures) Share your public key as clipboard, .asc file, or scannable QR code Export the active secret key as .asc for backup or migration to another device No internet permission declared — the APK literally cannot make network calls; all key exchange is out-of-band Camera permission is requested only at runtime, and only when you tap "Scan QR" No Google Play Services, no FCM, no analytics, no auto-backup Panic-trigger receiver wired (same Guardian Project API as Anon XMPP) — wipes every key, the roster, and any cached plaintext Free software under GPLv3 F-Droid repo: https://anonymous.gratis/fdroid/repo Tip portal: http://ieyezgeojxw73hv4szrkbreea3rd6ri7xfbevngi63uabothn226euyd.onion
