What is if you swipe left on tinder are they gone forever?

As an AI language model, I do not have access to the latest Tinder app updates or changes. However, historically, when you swipe left on someone on Tinder, it means that you are not interested in them, and they will not appear in your feed anymore. This does not necessarily mean that they are gone forever from the app, as they can still appear on other user's feeds and matches. Additionally, Tinder has a feature called "Rewind" that allows users to reverse their swipe and see the profile they swiped left on again.
