Billing and refunds
How do I request a refund?
Generally, all charges for in-app purchases are nonrefundable, and there are no refunds or credits for partially used periods.
Stompers purchases and subscriptions are handled through Apple, so refunds need to be requested through Apple instead of Stompers support.
Go to Apple's Report a Problem page, sign in with the Apple ID used for the purchase, find Stompers, and choose the refund option that best matches what happened.
