We're extremely careful when handling your personal information to make sure it's not accessible by any third parties. Credit card data is transmitted to us via SSL. The data is immediately relayed to our payment gateway and then discarded. Credit card data is never stored in our database (not even temporarily) and it exists in memory on our server for only a fraction of a second before it's discarded. As a convenience to you, we do store the last four digits of a credit card and the expiration month and date so that you may select a credit card to use at checkout.
