All profiles will have the display name, username, number of answers, number of likes, and of course all the questions you chose to answer. If your profile is in the Leaderboard, your profile will show also your country and position in it.
You have the option to go to your Settings and adding some additional info such as location, a website, a headline, and even a mini-bio of yourself.
Remember: Everything on an ASKfm profile is public unless you choose an option to chat privately!
