Introduction

VisoChain ("we", "our", "us") is committed to protecting your privacy and personal data. This Privacy Policy explains how we collect, use, store, and protect your information when you use the VisoChain network, VCDT token, and related services.

By using our services, you agree to the collection and use of information in accordance with this policy. We comply with applicable data protection laws including GDPR (General Data Protection Regulation) and CCPA (California Consumer Privacy Act).

Data We Collect

We collect the following types of information:

πŸ”— Blockchain Data (Public)

Wallet addresses, transaction hashes, data fingerprints, and smart contract interactions. This data is inherently public on the blockchain.

  • Wallet Address: Your Ethereum-compatible wallet address for authentication and rewards

  • API Usage: Request logs for partner platform integrations
  • Device Information: Browser type, IP address (anonymized after 30 days)

⚠️ What We Do NOT Collect

We do NOT store your actual images, personal files, or raw data. Only cryptographic fingerprints (hashes) are recorded on the blockchain to prove ownership and prevent duplicates.

Your information is used for the following purposes:

  • Authenticating your wallet connection
  • Recording data ownership on the blockchain
  • Distributing VCDT rewards for contributions
  • Preventing duplicate or fraudulent data submissions

  • Access Control: Strict API key authentication for partner platforms
