AppSumo Plus Refund Policy

After membership rewards have been used, your AppSumo Plus membership is non-refundable. Because the subscription is billed annually, you can cancel any time from the "​Plus subscription​" tile of your ​AppSumo account​ to end your membership and you will not be charged for the next year.

Keep in mind that AppSumo Plus membership rewards do not apply until the subscription is active.  Additionally, purchases made before your AppSumo Plus subscription are not eligible for retroactive discounts.
