LockMemo icon

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.
