After we changed everyone's passwords a couple of weeks ago, people were asking some questions about passwords and personal data. Firstly, we don't hold much personal data- as people have usernames, we don't know real names. We do ask for the year and date of birth to comply with the Children's Online Privacy Protection Act (COPPA). We ask for an active email account and send a link that has to be clicked on to complete the registration. This is to make it harder for automated registration by advertisers and spammers. We also ask where you're from, where you are based now and what your first language is. There are also optional fields where people can add biographical information and interests if they wish. Unless you use your real name as a username or connect via Facebook, the data is anonymous. If an acount is deleted, this information is deleted from our records.
