Apple will require apps in the App Store to allow users to delete their accounts within the app starting January 31, 2022. This update to the App Store Review Guideline 5.1.1 aims to give users greater control over their personal data. The requirement applies to all app submissions and encourages developers to review laws that may require them to maintain certain types of data. Developers must also ensure their app clearly explains what data is collected and how it is used.
