Apple is tightening its App Review Guidelines and the changes are significant. Apps are now required to enforce stricter age-gating, be fully transparent about any sharing of personal data, particularly with third-party AI, and avoid any form of “copycat” behavior. Reusing another app’s icon, name or brand without explicit permission will now result in a rejection.

Updated App Review Guidelines now available - Latest News - Apple Developer

The App Review Guidelines have been revised to support updated policies and to provide clarification. Please review the changes below: 1.2.1(a): This new guideline specifies that creator apps must provide a way for users to identify content that exceeds the app’s age rating, and use an age restriction mechanism based on verified or declared age to limit access by underage users. 2.5.10: This language has been deleted (“Apps should not be submitted with empty ad banners or test advertisements.”). 3.2.2(ix): Clarified that loan apps may not charge a maximum APR higher than 36%, including costs and fees, and may not require repayment in full in 60 days or less. 4.1(c): This new guideline specifies that you cannot use another developer’s icon, brand, or product name in your app’s icon or name, without approval from the developer. 4.7: Clarifies that HTML5 and JavaScript mini apps and mini games are in scope of the guideline. 4.7.2: Clarifies that apps offering software not embedded in the binary may not extend or expose native platform APIs or technologies to the software without prior permission from Apple. 4.7.5: Clarifies that apps offering software not embedded in the binary must provide a way for users to identify content that exceeds the app’s age rating, and use an age restriction mechanism based on verified or declared age to limit access by underage users. 5.1.1(ix): Adds crypto exchanges to the list of apps that provide services in highly regulated fields. 5.1.2(i): Clarifies that you must clearly disclose where personal data will be shared with third parties, including with third-party AI, and obtain explicit permission before doing so. Translations of the guidelines will be available on Apple Developer website within one month.
