Here at Miniclip, we are always concerned about your privacy.
That's why we want you to remember that some of the information that is visible in the game for other players is based on your Facebook profile and in-game settings.
As your account is connected with Facebook, then we cannot change the name or limit how much is visible. It is defined in the Facebook settings under the "Name" if you have full name there, this that's what the game shows. But you can change your Facebook name to limit the name visibility.
Unfortunately, at this point, that's all we can do regards in this issue. But do not hesitate to contact us if you need more guidance on how to hide your personal information.
