Your private vault, encrypted on your device.
Kryptos keeps your photos, videos, and notes in a local-first, end-to-end-encrypted vault. No accounts. No tracking. Optional sync to a server you run yourself.
Encrypted on your device
Photos, videos, and notes live in an encrypted database with strong authenticated encryption. Your keys are derived from your passphrase and never leave the device.
No accounts, no tracking
No sign-in, no analytics, no advertising, no crash-reporting SDKs. The developer runs no servers and collects nothing about you.
Optional self-hosted sync
Turn on Sync to pair with a server you run. Only end-to-end-encrypted ciphertext leaves your device — the server never sees your content or keys.
Biometric unlock
Your vault is gated by a passphrase and, if you enable it, Face ID / biometrics — matched by the operating system, never sent anywhere.
