Uses official StoreKit (iOS) or Play Billing Library (Android) for digital goods

Apple guideline 3.1.1 and Google Play Billing Policy both require that all digital goods sold within an app — subscriptions, consumables, non-consumables — are transacted exclusively through the platform's official billing API (StoreKit on iOS, Play Billing Library on Android). Routing a digital goods purchase through Stripe, Paddle, PayPal, or any other third-party processor via a webview or external link is not a gray area: it results in immediate rejection and, for repeat violations, developer account termination. Apple has removed apps and banned developer accounts for this specific violation. The business impact is severe: an app rejected during review has zero revenue until resubmitted, a process that takes days to weeks and requires removing the violating payment flow entirely.

Remove any Stripe, Paddle, or other third-party payment flows used for digital goods and replace them with StoreKit (iOS) or Play Billing Library (Android). The fastest cross-platform path is RevenueCat, which wraps both platform SDKs and handles receipt validation server-side.

npm install react-native-purchases
npx pod-install

// React Native — purchase via RevenueCat
import Purchases from 'react-native-purchases';
const { customerInfo } = await Purchases.purchasePackage(pkg);
if (customerInfo.entitlements.active['premium']) {
  unlockPremium();
}

For Expo projects: npx expo install expo-iap. For Flutter: add in_app_purchase: ^3.2.0 to pubspec.yaml. Physical goods and real-world services (delivery, rides, hotel bookings) are exempt — only digital goods require the platform store.
