DuoVault

What is DuoVault?

A photo & video vault for exactly two people. It starts private: no account, no sign-up. A 6-digit code becomes your encryption key, Face ID opens it, and it re-locks when you leave the app. When you're ready, one invite code turns it into a shared vault: whatever you add shows up on your partner's phone, with a shared timeline and an activity log (auto-deleted after 90 days). Everything is encrypted on-device before it syncs. The server only stores ciphertext; we can't see your photos.
