Storage Purchases <p> We send two pieces of personal data to our payment processor at the time of purchase: </p> <ul> <li> your Zotero username, in order to associate your payment with your Zotero account </li> <li> your email address, so that the payment processor can send you a payment receipt </li> </ul> <p> Zotero does not collect or store your credit card, banking, or other payment information. When you enter your full name, billing address, and account numbers to complete a Zotero purchase, this information passes directly to our payment processor, and it never touches Zotero servers. </p> Support Interactions <p> Most Zotero support occurs in the public Zotero Forums.
