This Privacy Policy governs the collection, processing, and protection of digital personal data by the operators of the TamizhCoin (TMZ) platform (“TamizhCoin”, “we”, “us”, or “our”), available at https://www.tamizhcoin.com. For privacy governance, we treat DPDP Act 2023 principles as a baseline while aligning with GDPR/CCPA expectations where applicable.

We process personal data in strict conformity with:
- Digital Personal Data Protection Act, 2023 (DPDP Act): Treating you as the “Data Principal” and respecting your statutory consent, correction, and grievance redressal rights.

3. Data We Collect and How We Obtain It
Web3 & Wallet Information
When you connect via MetaMask, RainbowKit, or WalletConnect, we observe your public Ethereum/Polygon wallet address and cryptographic signatures (Sign-In with Ethereum - SIWE). We never possess, hold, or have access to your private keys or seed phrases.
Optional Verification Data
For airdrop verification and anti-sybil auditing, you may optionally provide an email address for one-time OTP verification. Email addresses are encrypted at rest and solely used for authorization tokens.
Technical & Usage Metadata
Standard HTTP headers, browser user-agent, referring URLs, screen resolution, and aggregated telemetry to prevent DDoS attacks and optimize site responsiveness.
On-Chain Blockchain Data
Transactions executed on the Polygon network (claim contract, token transfers, voucher redemptions) are broadcasted to a public decentralized ledger and are immutable by nature.
