Apple Mandates New Notification System for Korean Developers
Apple announced on October 9, 2025 that starting January 1, 2026, developers based in the Republic of Korea must provide a server-to-server notification endpoint when registering a new Services ID or updating an existing Services ID to associate their website with an app using Sign in with Apple. The notification endpoint enables Apple to send updates about user account status, including changes in email forwarding preferences, account deletions in an app, and permanent Apple Account deletions. Apple advises developers to promptly update app data and server infrastructure upon receiving notifications, to follow guidance in WWDC20 session 10173 and TN3194, and to comply with applicable legal requirements for storing, retaining, and handling user account information. Additional resources include the App Review Guidelines and Human Interface Guidelines.
Policy update from a major platform (Apple) affecting Sign in with Apple identity flows; requires developer implementation and data-handling changes.

Apple updates Korea App Store age ratings
Apple announced changes to age ratings for apps distributed on the App Store in the Republic of Korea. Effective August 12, 2026, developers can override an app’s existing Korea age rating with any region-specific rating (All, 12+, 15+, or 19+) by providing the Game Rating and Administration Committee (GRAC) Rating Classification Number (RCN) when submitting their next app version. A second change, effective October 2026, will move two content descriptors—"infrequent profanity and crude humor" and "infrequent mature or suggestive themes"—from an "All" rating to 12+ for the Korean App Store. Apple notes that it generates age ratings from developers’ answers in the App Store Connect age rating questionnaire and that Games and Entertainment apps in Korea receive region-specific ratings in compliance with local regulation.
Apple Enhances Age Verification for Global App Downloads
Apple announced updates and beta availability for the Declared Age Range API and related tools to help developers meet age-assurance obligations under new regional and U.S. state laws. Beginning February 24, 2026, Apple will block downloads of apps rated 18+ in Australia, Brazil, and Singapore unless the user is confirmed as an adult; the App Store will perform automatic confirmation but developers may still have independent obligations. For Brazil, the API will return age categories if the user or parent/guardian agrees and will indicate the method of age assurance; apps flagged as containing loot boxes will be rated 18+ on the Brazil storefront. For new Apple Accounts in Utah (from May 6, 2026) and Louisiana (from July 1, 2026), age categories can be shared via the Declared Age Range API. Apple also expanded tooling (Declared Age Range API signals, PermissionKit Significant Change API, new StoreKit age-rating property, App Store Server Notifications, Significant Update Action) now available in beta.
Apple Launches Global Age Verification for Child Safety Compliance
Apple is rolling out a set of age-verification and “age assurance” tools worldwide to help developers comply with expanding child-safety laws. The company has made a Declared Age Range API available for beta testing that lets developers obtain a user’s age category without accessing personal data like date of birth. Starting immediately, Apple will block downloads of apps rated 18+ in Brazil, Australia, and Singapore until users confirm they are adults; developers may still have separate compliance obligations. In the U.S., Apple will share age-category signals with apps in Utah and Louisiana via the Declared Age Range API. In Brazil, games with loot boxes will be re-rated as 18+. Apple said the API provides new signals indicating whether regulatory requirements apply and whether parental permission is required for certain updates. Apple previously paused some Texas-focused plans while the law faces legal challenges.
