Apple has updated its App Review Guidelines to require explicit user permission and clear disclosure when apps share personal data with third-party AI. This change precedes Apple's planned AI-enhanced Siri in 2026, powered partly by Google's Gemini. The updated guidelines ensure compliance with data privacy regulations like GDPR and CCPA, potentially affecting apps using AI for personalization. Other revisions support Apple's Mini Apps Program, creator apps, loan apps, and crypto exchanges.
