Description by Paymaster Technologies Elektronik (from Google Play)

Secret Keeper is a standalone end-to-end encryption tool. It turns any
communication channel into a secure one: encrypt a message or a file, send
the result over a regular messenger or e-mail, or show it as a QR code —
only the intended recipient can decrypt it.

NO SERVERS, NO ACCOUNTS
• The app is fully offline: no sign-up, no phone number, no e-mail.
• Keys are generated on your device and never leave it.
• We collect no data at all — there is simply nowhere to send it.

CRYPTOGRAPHY
• Modern standard algorithms: X25519 + AES-GCM.
• Your identity is a 12-word seed phrase: it restores your profile on a
new device.
• Your address is a short string / QR code that is safe to share openly.
• The envelope format is open and documented (secretkeeper.net).

ACCESS PROTECTION
• PIN code and biometrics (Face ID / Touch ID / fingerprint).
• Duress PIN: a separate code that opens an empty profile.
• Automatic wipe after several failed PIN attempts.
• Locks when the app goes to background; screenshot protection (can be
turned off).

MESSAGING AND FILES
• Offline chats: per-contact message history, stored encrypted.
• Encrypt files of any type (.skf) — photos, videos, documents.
• Backup is a single encrypted file (.skb): its contents can only be
opened with your seed phrase.

INTEGRATIONS
• Tetatet Chat: link the apps and secret messages get delivered online
automatically.
• The Secret Keeper browser extension encrypts right on websites.
• Passwordless sign-in to services via QR (SK Login).

WHO IT IS FOR
Anyone who values privacy: personal correspondence, passwords and codes,
documents, medical and financial data. Secret Keeper requires no trust in
a middleman — verifiable cryptography instead of promises.

Privacy policy: https://secretkeeper.net/privacy

Recent changes:
• One-time codes (TOTP): scan a site's 2FA QR, the code with its timer is right on the card.
• Passkeys: Secret Keeper is a passkey provider on Android 14+, iOS 17+, macOS 14+, Windows 11; move passkeys between devices by QR.
• Sign in on websites and share Vault data with no middleman: the site identifies itself in the QR code.
