You can cancel your membership any time. To do this, you need to log into your dashboard, and click on membership in the drop down menu of your account. You can manage your membership here.
Once you cancel, you will lose access to expert messaging and your messaging history. You will also lose access to Renude's member credit programme, so you will no longer be able to redeem credit nor earn credit on purchases. You will still have access to your routine and expert notes, and will still be able to make purchases through your dashboard after you have cancelled the membership.
