I don't know if I need this here, but here goes.
- I promise not to share any contact information you share with me, with anyone else.
- I promise not to act like I know you on the street, just because you bought one of my books. Unless you specify otherwise.
- I promise not to share your credit card information if you purchase something through the cart system. Or go on an unapproved shopping spree with it. Mostly because I never see that part of the transaction anyway.
