PassKeyra

PassKeyra is a password manager built around one idea: your passwords are encrypted on your device before anything leaves it. One master password unlocks a locally encrypted vault, and the app works fully offline by default. Cloud sync and backup (Google Drive or OneDrive) are entirely optional, opt-in in settings. If you turn them on, the servers only ever receive encrypted data, not readable by Google, Microsoft, or me. Free tier (no time limit): unlimited vault entries, biometric unlock, password generator, custom categories, fully offline, available in English, French, and Spanish. Premium (€2.99/month or €29.99 lifetime, no subscription required): automatic sync across devices, automatic cloud backup, a security report flagging weak, old, or reused passwords, and an ad-free experience. Full transparency: the free tier shows a small non-personalized ad banner (removed in Premium), and the optional sync relies on Firebase. Because of that, it's not F-Droid eligible today. The code is open source under GPL-3.0, so the zero-knowledge claim is something you can verify yourself rather than take my word for it: github.com/Pass-Keyra/PassKeyra
