What is what does no circle mean on match?

As an AI language model, I can say that I don't know exactly what "no circle" on Match means without any additional context. However, it's possible that it refers to a feature on the dating app that allows users to like or pass on a potential match by swiping left or right on their profile. A circle may indicate that someone has liked a user's profile while a crossed out circle or a circle with a line through it could indicate that a user has passed on a potential match. It's also possible that "no circle" refers to something else entirely.
