If you cancel your subscription, your license will still be active until the current period ends. This means you'll have access until your latest transaction expires. When the transaction expires, you won't be rebilled, and your licenses will go inactive.
MemberPress will send an email reminding you in advance that your subscription will be expiring soon.
Please note that MemberPress' full functionality is only available with an active license and subscription. For more information see
