Privacy Policy
Your privacy matters to us. This policy explains how OnChainWin collects, uses, and protects your information.
1. Information We Collect
- Wallet Addresses: When you connect your cryptocurrency wallet, we collect your public wallet address to facilitate raffle participation and prize distribution.
- Transaction Data: All raffle entries, ticket purchases, and prize distributions are recorded on the Base blockchain and are publicly accessible.
- Usage Data: We may collect anonymous usage analytics such as page views, feature interactions, and device information to improve our platform.
- Communication Data: If you contact us via our contact form, we collect the name, email, and message content you provide.
2. How We Use Your Information
- To process raffle entries and distribute prizes through smart contracts.
- To display your participation history and winnings on your profile.
- To improve and optimize our platform and user experience.
- To respond to your inquiries and provide customer support.
- To comply with legal obligations and prevent fraudulent activity.
3. Blockchain Data
- OnChainWin operates on the Base network. All raffle-related transactions are recorded on the public blockchain and are immutable. This includes wallet addresses, ticket purchases, and prize distributions.
- We cannot modify, delete, or hide blockchain data once a transaction has been confirmed. This transparency is a core feature of our platform.
4. Cookies & Local Storage
- We use essential cookies and local storage to maintain your wallet connection session and remember your preferences.
- We may use analytics tools to understand how users interact with our platform. These tools may set their own cookies.
- You can disable cookies in your browser settings, though this may affect platform functionality.
5. Third-Party Services
- Chainlink VRF: We use Chainlink Verifiable Random Function for provably fair winner selection. Chainlink processes on-chain data to generate random numbers.
- Wallet Providers: We integrate with third-party wallet providers (e.g., MetaMask, Coinbase Wallet). These services have their own privacy policies.
- Blockchain Infrastructure: We rely on RPC providers and blockchain explorers that may log public transaction data.
6. Data Security
- We implement industry-standard security measures to protect any off-chain data we store. However, please note that blockchain transactions are publicly visible by design.
- We do not store private keys or seed phrases. Your wallet security is your responsibility.
7. Your Rights
- You may request deletion of any off-chain personal data we hold (e.g., contact form submissions).
- On-chain data (transactions, wallet interactions) cannot be deleted due to the immutable nature of blockchain technology.
- You may disconnect your wallet at any time to stop further data collection.
8. Contact Us
- If you have questions about this Privacy Policy, please contact us at info@onchainwin.com or through our contact page.
