Does Coinbase sell data?

I've heard some rumors that Coinbase, one of the leading cryptocurrency exchanges, sells user data. Can you clarify whether this is true? Are there any policies or procedures in place to ensure that customer information is kept secure and private? It's important for me to understand the level of trustworthiness and transparency when it comes to handling sensitive financial data. Could you elaborate on how Coinbase approaches data privacy and security, and reassure me that my information is safe?
