1. Information We Collect
twin3 collects minimal data necessary for identity verification: wallet addresses, OAuth provider identifiers (no passwords), and verification completion status. All data is processed in accordance with applicable data protection regulations.
2. On-Chain Data
Your Soulbound Token (SBT) and Twin Matrix data are stored on the BNB Smart Chain blockchain. On-chain data is public and immutable by design. We do not control blockchain data once it is written.
3. Data Storage
Off-chain verification state is stored in Google Cloud Firestore with encryption at rest. Session data uses httpOnly cookies with secure flags. We do not sell or share your data with third parties.
4. Third-Party Services
We use Google OAuth, Discord OAuth, LINE Login, Telegram Login, and Passkey (FIDO2) for identity verification. Each provider's privacy policy applies to their respective services.
5. Your Rights
You may request deletion of your off-chain data by contacting us. On-chain SBT data cannot be deleted but can be burned (revoked) by the token holder.
