What personal information do you store?
Just the basics pertaining to your account login information, like username and password. And of course, we store the content that you choose to upload and configure on your book pages—though that's not personally identifiable information. That's just content.
As it pertains to sensitive personal information (e.g. credit card data), we store nothing. Nada. Zilch. Zippo. And we never, ever ask you for information like your social security number, date of birth, or similar.
