The security model your important documents deserve
Encrypted files live in your own Google Drive, not on our servers. Google's ownership metadata proves who created each document and when — tamper-proof origin verification.
The encryption key is derived from both your identity and your recipient's. They can't decrypt without your physical ID card — which they'll only receive after you're gone.
AES-256-GCM with Argon2id key derivation (64MB memory-hard). Encryption happens entirely on your device — your identity information is never stored, transmitted, or logged.
Use any government-issued ID — national ID, passport, SSN, Aadhaar, My Number. The app normalizes all formats automatically. One sealed document works across all devices and platforms.
Layer 1: owner's ID card. Layer 2: recipient's own identity. Layer 3: optional secret phrase delivered through a separate channel — sealed letter, safe deposit box, or verbal instruction.
We never see your documents, your identity information, or your encryption keys. Everything is encrypted on your device. Our server only handles Google sign-in — nothing else.
Choose any file — will, insurance policy, property deed, bank details, or personal letter.
Your ID number + date of birth, and your recipient's. Optionally add a secret phrase.
The app encrypts the file on your device and uploads it to your Google Drive.
Send the recipient a link. They'll need YOUR physical ID card + their own identity to unlock.
