Privacy & KYC

GRIPLOCK is built for privacy. Zero-knowledge proofs let you prove eligibility without revealing personal data. Stealth mode keeps your activity hidden.

​
Privacy Philosophy

Prove Without Revealing

Zero-knowledge proofs verify facts without exposing underlying data.

No Cloud Storage

Your credentials never leave your device. No servers store your identity.

Ephemeral Sessions

Session data auto-destructs. Nothing persists after logout.

Stealth Mode

Masked balances, hidden transactions, incognito operation.

​
Zero-Knowledge KYC

Traditional KYC requires uploading ID documents to centralized servers. GRIPLOCK uses zero-knowledge proofs for privacy-preserving verification.

Data Handling

​
What GRIPLOCK Never Stores

  • Seed phrases or private keys
  • PIN codes
  • Personal identity documents
  • Transaction history on servers
  • IP addresses or device fingerprints

​
What Stays Local

  • Encrypted session data (browser only)
  • ZK proof attestations
  • Spending limit preferences
  • UI settings

​
Filecoin Storage (Optional)

For users who want encrypted backups: 
// Backup is encrypted with your NFC+PIN derived key
{
  storage: "filecoin",
  encryption: "AES-256-GCM",
  access: "only you can decrypt"
}
  • Encrypted preferences backup
  • Decentralized, censorship-resistant
  • Only accessible with your NFC card + PIN

​

​
Compliance Notes

Zero-knowledge KYC satisfies regulatory requirements while protecting your privacy. Services receive proof of compliance, not your personal data.
  • Regulatory friendly: ZK proofs are accepted for KYC/AML compliance
  • Reusable: Verify once, reuse proofs across services
  • Revocable: You control which proofs are active
  • Auditable: Cryptographic proofs are verifiable
