Self-Sovereign Cognitive & Behavioral Health.
Democratizing access to 20 validated neurodevelopmental, cognitive, and mental health screening instruments with deterministic client-side scoring, zero centralized tracking, and cryptographic Arbitrum notarization.
Why Self-Sovereign Health Data Matters
Zero-Server Scoring
Every psychometric calculation runs deterministically inside your browser engine. Your intimate psychological questions and answers never pass unencrypted over the wire.
Client-Side Envelope Encryption
Assessment bundles are encrypted with AES-256-GCM and wrapped in 2048-bit RSA-OAEP keys. Only you possess the private keys to decrypt your historical cognitive records.
Arbitrum One Notarization
Public RSA keys are notarized on the KeyRego smart contract, and encrypted payloads are recorded to your closed Personal Data Wallet MessageGroup with zero gas barriers.
