Attestations create log entries that become part of the permanent record of the blockchain. Here are some best practices to avoid violating users’ privacy:

Obtain explicit consent from users for personal information. Clearly inform them what data is being collected, why it is being collected, and how it will be used.

Sensitive data should not be stored onchain, in any way. If you need a smart contract to verify it in the future, you can use the hash of the sensitive data rather than the data itself.

Even when storing sensitive data offchain, you need to ensure it is stored securely using encryption, proper authentication and authorization, etc.
