Q - How long do you retain members' billing information, and how do I close my TNGP user account?

A - We don't retain ANY billing information. All data is deleted immediately after each credit card transaction is completed. In fact, after your tokens are issued, any link between your credit card and TNGP account is deleted as well.

To "close" your TNGP account, just stop using it. It has no link to any of your personal information, including your credit card information. It's just an anonymous username and password.
