If you register with our site, we require your email and name. Nothing else.
You may choose to give us other information, like usernames or user IDs from other sites in order to enhance your experience, but you have full control over your data. At your request, all of your information that we have about you can be given to you, and you may also choose to delete it along with your account. If you have any chess games registered in our system, your membership entry will be converted to an anonymous one and the games will remain in the system with no ties to you.
