Apple has updated its App Store Review Guidelines, introducing a significant rule that requires developers to obtain explicit user consent before sharing personal data with third-party artificial intelligence services. The new policy, under section 5.1.2 for Data Use and Sharing, marks the first time Apple has specifically mentioned "AI" in its guidelines, reflecting the technology's increasing integration into apps. This move is seen as a proactive step to enhance transparency and data protection as generative AI applications become more popular. Developers must now clearly inform users if their data, including conversational inputs, will be used for training or analytics by AI models and secure their permission beforehand. The policy aims to prevent the hidden use of personal data by the rapidly growing number of AI-powered applications available on the App Store.
