Store Compliance

Displaying an external payment link inside your application is subject to Apple's and Google's rules. That is your responsibility, not Inflow's. Our checkout page, for its part, is a web page accessible everywhere.

What to know

• Apple requires the StoreKit External Purchase Link Entitlement, and displays a system disclosure sheet before leaving the app.
• The eligibility criterion is the user account's App Store storefront (SKStorefront.countryCode), not the IP address.
• In the EU, you cannot offer both in-app purchase and the promotion of external offers on the same storefront. In the United States, you can.
• Google offers its external link and alternative billing programs, with fee schedules and reporting obligations.
• Apple and Google both impose external transaction reporting, with attribution windows.

⚠️

Warning

These rules change quickly. Check the currently applicable state with Apple and Google before any submission.

Where the store rules stop

The rules above govern how you link out from your app. They are separate from the rules that govern the payment itself once the buyer is on the checkout page — which country you can collect from, and how tax is applied. For those, see Merchant of Record eligibility and Tax & Pricing Modes.
