SafeKey

SafeKey is a local-first encrypted vault for passwords, crypto seeds, and sensitive documents — built by AlfaNest Labs.

Your data is encrypted directly on your device using PIN and optional biometric unlock. Nothing leaves your device without your explicit action. The server never sees your vault contents — not even in encrypted form, unless you choose to enable sync.

WHAT YOU CAN STORE

• Passwords and login credentials

• Crypto wallet seeds and private keys

• Documents and sensitive notes

• Any text secret you need to keep safe

SECURITY FEATURES

• AES-256 encryption with Argon2id key derivation (native code, not JavaScript)

• PIN unlock — your key never stored in plaintext

• Biometric quick unlock — PIN protected by device keystore + biometrics

• Shamir Secret Sharing — split any secret into N shares, M-of-N required to recover

• NFC card support — pair an NTAG physical card as a hardware second factor

BACKUP AND RECOVERY

• Export your vault as an encrypted .sfk container file

• Import .sfk backups on any device running SafeKey

• Shamir split recovery for distributed key custody

SAFEKEY PRO (optional, one-time purchase)

• End-to-end encrypted sync across devices — zero-knowledge, server sees only ciphertext

• Purchase at sfk.alfanestlabs.com — no Google Play subscription, no recurring fees

COMING SOON

• Dead Man's Switch — automatically release sealed messages to trusted contacts after a period of inactivity

• Custodian invite — distribute Shamir fragments to trusted people via the app

PRIVACY

SafeKey does not collect analytics, crash reports, or any usage data. There are no third-party SDKs. Your vault is yours.
