A. Anything from your favorite color to the type of music you listen to; Tinder will prompt you as you add new information, but it's up to you whether or not you want to share any private details at all about yourself online. In addition, there is a "Comments" section that users can write in themselves, so if you don't like any of the questions asked by Tinder and don't want others using them on their profiles either, then this is where they should be changed to reflect what's more important for you personally.
