If you (would have) read the PP, you could know that it reads pretty well, as far as our favourite part concerns. And as we expected, you can delete your account with the exception of two reasons, exactly the one you can read in our AK FAQ: technical and legal. Sit with us and read:
You may ask to have the information on your account deleted or removed; however, because we keep track of past purchases, you cannot delete information associated with past purchases. Also, as a security measure we “back up” the data stored on our systems, and such prior information cannot be completely removed from our databases. As a result, you should not expect that all of your Personally Identifiable Information will be completely removed from our backed-up databases.
So go ahead and ask them (be logged in): https://secure.rakuten.com/AC/contact/ContactEmail.aspx
