About purchases not billed through the App Store or the App Store's In-App Purchase system
If you paid for an app, purchase within an app, or subscription outside of Apple's ecosystem, contact the developer for billing support or a refund. Apple is unable to provide support for these purchases.
Purchases that aren't supported by Apple
In the European Union: Buying apps from alternative app marketplaces, and all purchases or subscriptions made within apps installed from alternative app marketplaces
Apps from the App Store with External Purchases that don't use the App Store's In-App Purchase system
Making purchases or sharing payment method information outside the App Store and the App Store's In-App Purchase system comes with risk of new threats to security and privacy. You might have to share your payment information with additional parties, creating more opportunities for bad actors to steal sensitive financial information. There are risks of not receiving digital goods and services that you pay for, and it might be more difficult to learn how to cancel a subscription. Helpful App Store features — like Report a Problem, Family Sharing, subscription management, and Ask to Buy — also are not available for these transactions.
You can easily tell what purchases you've made that are supported by Apple. View your purchase history associated with your Apple ID. For purchases made outside the App Store's private and secure commerce system, Apple won't be able to assist users with refunds, purchase history, subscription cancellation and management, violations of user data privacy, abuse, or fraud and manipulation, in addition to issues that make the user experience less intuitive.
Contact the developer for help with purchases not billed through the App Store or the App Store's In-App Purchase system
If you originally downloaded the app from the App Store and also made purchases outside of the App Store and the App Store's In-App Purchase system, contact the developer.
If you originally downloaded the app from an alternative app marketplace in the European Union, check where you downloaded the app from and contact the developer of the alternative app marketplace or the app.
