Privacy Policy

1. Information We Collect

When you use the Mystery Gift TEE Randomness Service, we may collect:

• Wallet Addresses: Public Solana wallet addresses used for payments
• Transaction Data: Payment transaction signatures for verification
• Request Metadata: Timestamps, request types, and attestation data
• Technical Data: IP addresses and request headers for security purposes

2. How We Use Information

We use collected information to:

• Process and verify payments
• Prevent fraud and replay attacks
• Generate usage statistics (anonymized)
• Improve and maintain the Service

3. TEE Security

All randomness generation occurs within an Intel TDX Trusted Execution Environment. This means:

• Random seeds are generated in hardware-isolated memory
• Even service operators cannot access or predict random values
• Remote attestation proves the integrity of the execution environment

4. Data Retention

We retain:

• Payment signatures: 1 hour (for replay attack prevention)
• Usage statistics: Aggregated and anonymized, retained indefinitely
• Error logs: 30 days for debugging purposes

5. Data Sharing

We do not sell or share your personal information with third parties, except:

• When required by law
• To prevent fraud or security threats
• Anonymized, aggregated statistics may be shared publicly

6. Blockchain Transparency

Please note that Solana blockchain transactions are public. Wallet addresses and transaction data are visible on the public blockchain regardless of our privacy practices.

7. Your Rights

You have the right to:

• Access information we hold about your wallet address
• Request deletion of non-essential data
• Opt out of non-essential data collection
