If you would like to cancel your Membership auto-renewal, please log in to your paid account. Click the "profile" icon in the upper right corner, and click 'My Account'. Then scroll down to "Billing Info" and click "Edit Membership."
If you are not given the option to disable auto-renew, you've likely already turned it off! If you would like to double check, you can send an email to firstname.lastname@example.org and we will be happy to take a look.
If you are a 'free' member, you won't see any auto-renewal option. If your most recent subscription payment was declined, your auto-renewal is automatically disabled.
