Auto-renewal is automatically set when you signed up. You will get a receipt from Stripe when you join for the membership. You will also find a link to update the account settings in case you wish to switch off auto-renewal.
30 days before your membership renews, you'll receive emails from Stripe to update you.
If you wish to turn-off auto-renewal, you'll have to either go to Stripe to do this or contact our support team at [email protected] and we will assist you further.
