Google Play Billing vs ProtectMyGame

Google Play Billing lets developers sell digital products and content in Android apps through one-time purchases or subscriptions. It is for digital items; developers selling physical goods or services are directed to the Google Pay SDK. One-time products may be consumable for repeat purchases or non-consumable for a lasting benefit, and can grant permanent access or a particular non-renewable use. Subscriptions grant defined benefits for a set period and support base plans, offers, prepaid plans, and add-on entitlements. The Play Billing Library connects an Android app with Google Play Services to retrieve localized offerings and launch purchase flows. Google recommends a secure backend using the Play Developer API for purchase verification and subscription management. That API can check purchase status and modify or cancel recurring purchases. Cloud Pub/Sub delivers notifications about changes to Google Play-managed subscriptions. Purchases that are not acknowledged within three days are automatically refunded. Google says service fees vary by developer and transaction; its overview says 97% of developers distribute apps and use Google Play at no charge, and 99% of developers subject to a service fee are eligible for a fee of 15% or less through available programs. The listed plan is free.
