When to Use This Skill

Use when you need to:

• Add in-app purchases or subscriptions to a KMP app
• Gate premium features behind a purchase check
• Handle Play Billing (Android) and StoreKit 2 (iOS) with shared domain logic
• Restore purchases across devices or after reinstall
• Validate receipts client-side or server-side

Freshness rule: Play Billing Library and StoreKit 2 APIs change between major versions — recheck Google Play Billing and Apple StoreKit release notes before upgrading.
