You can refund your All-Access Pass membership 7 days from the purchase date, after this you can only cancel your membership. Your membership will auto-renew until cancelled. You will still have access to your membership until your subscription ends. To avoid any charges, you must cancel the subscription prior to the next renewal date.
Please keep in mind that all Personal Development School subscriptions are set to auto-renew, which means the system will charge you automatically on your renewal date and all renewal payments are non-refundable. You can view each plan's renewal date here.
