Cancel customer memberships
To cancel an individual customer's membership, simply head to your Audience dashboard, search for their name or email, and click Cancel Subscription.
If the customer subscribed to your membership for free ($0), then you will also see a "Delete" button above the "Cancel Subscription" button to delete the customer from your dashboard completely.
However, as a creator, you also have the following options:
Preventing new customers from subscribing
If you're looking to keep all your existing subscribers and not accept any new subscribers, simply Unpublish the product. Any new customers will not be able to buy or find the product, while existing customers will continue to be charged and have access to their files.
Deleting a membership product
To cancel a membership for all customers, go to your Products dashboard, hover over the product you'd like to delete. and click the 'Delete' button on the right.
When building your product, you can set your membership to terminate after a set number of months.
