Your most important documents, protected by the strongest encryption.
Zero-knowledge vault. Client-side encryption. Only you hold the key.
How It Works
Secure Digital Vault for Documents and Instructions
Your most sensitive documents are encrypted on your device before upload. Only an authorized unlock — your password or appointee keys — can reveal the contents.
Zero-Knowledge Encryption
Your documents are encrypted in your browser before they ever leave your device. Our servers store only encrypted blobs — we literally cannot read your files.
Secure Heir Access
Your encryption key is split into shares — heirs need a configurable threshold (e.g., 3 of 5) to unlock the vault. When heirs submit their shares, a grace period starts. You're notified and can deny access.
Emergency Master Key
A separate emergency key is split between you and our server — both parts are required. Generate a one-time recovery key and store it offline securely.
Password-Based Unlock
We never receive your vault password. It's used locally to decrypt the vault master key. Your password never leaves your device.
Grace Period Protection
You're notified of access attempts and can deny unintended access before the vault opens. Full control over who sees your documents and when.
Owner Control & Revocation
Update appointees and regenerate keys to invalidate prior access when circumstances change. Sessions auto-lock after inactivity. File versioning tracks every change.
