Verify Identity Without Exposing Personal Data
NoNo uses zero-knowledge proofs to let users prove who they are — without handing over their passport, address, or date of birth.
How It Works
1. Verify Once
Complete a one-time identity check using your government ID and a selfie.
2. Proof Generated
A zero-knowledge proof is created — cryptographic confirmation with no personal data attached.
3. Verified Privately
Present your proof anywhere it's needed. No re-verification. No data exposure.
Why NoNo
No Data Stored
We store your verification proof, not your personal data. ID documents are destroyed automatically after 30 days. No SSN, ever.
Zero-Knowledge Proofs
Cryptographically prove facts about yourself — age, identity, address — without revealing the underlying information.
KYC Compliant
Meet compliance requirements without the liability of storing sensitive customer data.
Verified, then gone.
ID documents are automatically destroyed 30 days after verification. What remains is the compliance record — verified, passed, timestamped — and an irreversible fingerprint that catches banned customers coming back. No SSN, ever. No cross-store tracking, ever.
Built for Businesses
Add privacy-first KYC to your product without the data liability. Your users verify once — you get compliance, they keep their privacy.
