Apple Blocks Third-Party Accessories from Using EU Notifications for AI Training
In response to the EU's Digital Markets Act, Apple has opened real-time activity and notification access to third-party accessories in iOS 26.5 Beta 1. To safeguard core data, Apple has established strict privacy boundaries in its developer agreement, explicitly prohibiting the misuse of user information.

The latest developer terms strictly forbid any third-party device accessing iPhone notifications from using the data for advertising or user profiling. Apple is particularly vigilant about its technical infrastructure, banning third-party companies from using this real-time notification data to train AI models.
To eliminate potential data leaks, the new rules mandate that all notification data be decrypted locally on the accessory itself, preventing uploads to cloud servers. This approach blocks developers from intercepting sensitive content—such as text messages, emails, or medical alerts—through remote nodes, ensuring physical privacy isolation.
Apple stresses that this sharing system operates at the system level, with users retaining ultimate control. If a user disables the feature in system settings, no third-party accessory can forcibly access data, putting the choice firmly in the consumer's hands.
From AIbase's perspective, Apple's strategy is a high-stakes balance between regulatory compliance and privacy protection. While forced to open its ecosystem, Apple is drawing a "no AI training" red line to uphold its core role as the guardian of user data.
For developers, this detailed compliance framework significantly narrows the room for "technical arbitrage." In the 2026 privacy landscape, a key challenge for hardware makers will be enhancing accessory intelligence without crossing these clear boundaries.
