Family Vault
A secure vault for your family's data. Everything stays on your phone.
Why it exists
Your child's ID number, a passport series, an insurance policy number — the details you need once a quarter and can never remember where you wrote down. A note in a drawer gets lost, a note on your phone sits there in plain text, and the cloud means handing your family's data to a company you don't know.
Family Vault keeps them in one place, encrypted with the same standard that protects banking data — and never sends them anywhere.
Security
AES-256-GCM encryption
Authenticated encryption — it detects any attempt to tamper with your vault file.
Key derived from your password
PBKDF2 with SHA-512, 310,000 iterations, a unique salt for every vault.
Zero-knowledge
Decrypted data lives only in RAM and is wiped the moment you lock the app.
Nothing leaves your phone
No accounts, no servers, no analytics, no ads. The app doesn't need the internet.
Masked by default
Sensitive fields stay hidden until you reveal them with a single tap.
Backups
Export and import an encrypted .sejf file — moving to a new phone is easy.
