When you create an account, we ask the month and year you were born. We use it only to check that you’re 13 or older, and we don’t save it.

  • CardBull accounts are for people 13 and older.
  • Under 13? A parent or guardian can create an account in their own name and share it with you.
  • Under 18? A parent or guardian must agree before you choose a paid plan.

Parents: you can ask us to delete an account made by a child under 13. Email support and we’ll take care of it.
