Zecuri

Zero-knowledge password manager. EU-built, privacy-first.

Zecuri is a zero-knowledge password manager built for privacy. Your passwords are encrypted on your device before leaving it. Only you hold the keys. WHY ZECURI - Zero-knowledge by design. Your master password derives every encryption key locally with Argon2id. Our servers only ever see signed ciphertext. - End-to-end encrypted sync. Your vault syncs across the Chrome extension and the iOS app within seconds. The server cannot decrypt it. - One master password. No recovery codes to lose, no second account to manage. - EU-built. Engineered in Sweden, hosted in the EU, GDPR-compliant. No analytics, no telemetry, no tracking. - Open and auditable. The vault encryption, sync protocol, and client code are open for review. WHAT YOU GET - Secure password storage with site favicons, search, and tags - One-click autofill on login forms (Ctrl+Shift+Y to trigger manually) - Strong password generator with adjustable length and character sets - Credit cards, secure notes, and identity records alongside logins - AES-256-GCM vault encryption and Ed25519-signed sync metadata - Auto-lock when your system goes idle CROSS-DEVICE Start on Chrome, continue on iOS. The Zecuri iOS app uses the same zero-knowledge protocol, so changes on one device appear on the other almost instantly. More platforms are on the roadmap. PRIVACY YOU CAN VERIFY - Master password is never sent to the server - Vault data never leaves your device unencrypted - Sync server stores only Ed25519-signed metadata it cannot read - No third-party analytics, no ad SDKs, no telemetry pings - Hosted in the European Union under GDPR PERMISSIONS, IN PLAIN ENGLISH Zecuri only reads URLs to detect login fields and inject autofill when you ask for it. It never sends unencrypted vault data anywhere. See the permissions justification in the listing for a per-permission breakdown. ROADMAP - Firefox and Safari extensions - Android app - Passkey (WebAuthn) support - Browser autofill for addresses and payment methods REQUIREMENTS - Chrome 120 or later - No account creation required — install, set a master password, you're done SUPPORT Bug reports and feedback: github.com/linespotting/zecuri Contact: privacy@zecuri.com Privacy policy: zecuri.com/legal/privacy Terms: zecuri.com/legal/terms
