Google's parent company, Alphabet, has recently unveiled major modifications to the business model of the Google Play Store. These changes include a reduction in the standard service fee for in-app purchases (IAP) from 30% to 20%, a decrease in subscription service fees to 10%, and the complete opening up to third-party payment systems and app stores. The reform categorizes fees into basic service fees and payment processing fees: Regarding basic service fees, the IAP rate for new users will be lowered to 20%. Premium apps that participate in the 'App Experience Program' or 'Game Upgrade Program' are eligible for an even further reduction to 15%, while the rate for existing users will remain at 20%. Subscription service fees will be uniformly reduced to 10%. As for payment processing fees, developers who utilize Google's official payment system will incur an additional 5% fee in the U.S., UK, and European Economic Area. However, no fees will be applied for third-party payment options. Furthermore, Google has announced the removal of 'anti-steering' restrictions. This allows developers to inform users about external payment options within their apps and provide redirect links. Simultaneously, Google has launched the 'Registered App Store' program, enabling third-party app stores that meet security standards to be installed and run more easily on Android devices. These new regulations will be implemented globally in stages, with full implementation anticipated by 2027. The reform is a result of a multi-year antitrust lawsuit settlement between Google and Epic Games. It signifies a restructuring of the settlement and distribution rules within the Android ecosystem and is expected to have a significant impact on the mobile app and gaming industries.
