Celestial Data Vault is a zero-knowledge, end-to-end encrypted home for your passwords, files, cards, documents and private notes — sealed with AES-256 and unlocked only by you, on any device, anywhere in the galaxy.
Stop scattering secrets across sticky notes, spreadsheets and browser autofill. Celestial keeps logins, payment cards, identity documents, API keys and encrypted files in a single vault that only your master password can open — not us, not anyone.
Everything a modern vault should do — and the guarantees most of them quietly skip.
Encryption and decryption happen only on your device. Your master password never leaves it, and we couldn't read your vault if a court, a hacker, or our own engineers asked.
Unlock with Face ID, Touch ID, Windows Hello or a hardware key. Store and autofill passkeys for a password-free future — without giving up control.
Native apps for iOS, Android, macOS, Windows and Linux, plus browser extensions for Chrome, Firefox, Safari, Edge and Brave. One vault, perfectly in sync.
Celestial Watchtower scans known breaches and dark-web dumps, then alerts you the moment a stored credential is exposed so you can rotate it in seconds.
Share a login, a file, or a whole collection with end-to-end encrypted links. Role-based access, expiring shares, and full audit logs for organisations.
Nominate trusted contacts who can request time-delayed access to your vault if something happens to you. Your legacy stays protected and recoverable.
Every item is encrypted with AES-256-GCM using a key derived from your master password through 250,000 rounds of PBKDF2-SHA256. We only ever receive an opaque blob of ciphertext. The keys stay with you.
