Track lab results over time with beautiful charts and complete privacy. Zero-knowledge encryption means only you can see your data.
Simple tools for tracking, visualizing, and securing your health data.
Your password encrypts data in your browser. The server stores only ciphertext it cannot read.
Visualize biomarker trends over time with interactive charts and reference range overlays.
Install as a native app. Works offline with a local encrypted vault in your browser.
Every sync creates a new version. Roll back to any of your last 10 snapshots.
Import lab results from CSV files. Export your data anytime in CSV, JSON, or encrypted .bwdb.
Proprietary .bwdb format is fully documented. Your data is never locked in.
Upload a lab report and let AI extract your biomarkers automatically. Available with Premium.
Your password derives two keys: one for encryption (stays in your browser) and one for authentication (hashed on the server).
Open your SanaVault to enter biomarker results manually or import from CSV. View trends in tables and charts, all in your browser.
Your entire database is encrypted as a single blob and uploaded. The server stores it but cannot decrypt it. Works offline too — changes sync when you reconnect.
The server never sees your password, encryption key, or unencrypted data.
AES-256-GCM encryption happens entirely in your browser using the Web Crypto API. Your password never leaves your device.
PBKDF2 derives two independent keys from your password: one for encryption and one for authentication. The server only ever sees a hash of the auth key.
The server stores encrypted blobs as opaque binary data. Even with full database access, your health data remains private.
The .bwdb binary format and all cryptographic operations are fully documented. Verify the implementation yourself.
Free, encrypted, and private. No credit card required.
