How paying works
Paddle is our reseller and merchant of record: it takes the payment, sends the receipt and handles refunds under our refund policy. We never see your card details. In the apps, purchases go through Apple or Google instead.
You can also leave a tip on Ko-fi; it unlocks nothing, it just says thanks.
