Your vault. Yours alone.

End-to-end encrypted vault for passwords, 2FA codes, notes, attachments, and crypto seed phrases. Stored on your device. Synced — if you want — via your own Git repository.

What you get

One vault for everything you need to remember.

Designed for people who'd rather not hand their secrets to a cloud password manager. Same convenience, none of the third-party trust.

Encrypted by design

AES-256-GCM for content, Argon2id (RFC 9106) for key derivation, HMAC for filename obfuscation. Your master password never leaves the device.

Passwords + 2FA codes

Stores credentials with custom fields, supports Google Authenticator-compatible TOTP codes, and imports your existing Google Authenticator export in one tap.

Encrypted attachments

Attach screenshots, PDFs, or text files (security questions, bank code cards, ID scans). Preview them in-app — bytes never touch disk decrypted.

Seed-phrase storage

BIP39-validated seed phrases with paste-blocked entry, biometric-gated reveal, and screenshot-blocked viewer. Built for crypto users who currently keep seeds on paper.

Encrypted notes

Markdown notes with image attachments. Same encryption envelope as your passwords — anything you'd write in Apple Notes, but actually private.

Your sync, your choice

Push your vault to any Git repository (GitHub, GitLab, self-hosted) using HTTPS + a personal access token. Or don't — local-only works perfectly.

Our promise

Privacy isn't a feature. It's the architecture.

We can't read your data — even if we wanted to. Here's the full picture.

What LockMemo does

  • Encrypts everything on your device before it can be synced anywhere.
  • Uses your master password as the only key — we never see it, never store it.
  • Lets you sync via your own Git remote (you control the credentials).
  • Locks the app automatically and protects the screen from recording when viewing seed phrases.
  • Ships zero analytics, zero ad SDKs, zero crash-reporting telemetry.

What LockMemo never does

  • Collect your name, email, phone, location, contacts, photos, or browsing data.
  • Show you ads.
  • Sell, share, or sublease your data — there's no data to sell.
  • Require an account. There is no LockMemo account; you only have a master password.
  • Phone home. No backend, no servers, no logs.
