TL;DR
- Open Following. It lists active and inactive subscriptions. Unsubscribe there.
- The terms also let you switch off Auto-Renew on that creator’s account. Either path is the cancellation.
- You are billed for the period you are in, and you can still view that creator until it ends.
- No refund of the subscription, and the same rule covers tips, streams, paid posts, and paid messages, unless the terms were violated. That exception goes to support@onlyfans.com.
- Each creator is a separate subscription. There is no “cancel all” in the help text.
