Under the pressure of the EU Digital Markets Act, Apple has officially opened real-time activity and notification access to third-party accessories in iOS 26.5 Beta 1. However, to prevent core data leakage, Apple has added extremely strict privacy red lines in the developer agreement, clearly prohibiting the abuse of user information.
According to the latest developer terms, all third-party devices that access iPhone notifications are strictly prohibited from using the obtained information for advertising or user profiling. More specifically, Apple is strictly guarding the technical infrastructure, prohibiting third-party companies from using these real-time notification data to train AI models.
To block all potential data leakage paths, the new regulations require all notification data to be decrypted locally on the accessory, without being uploaded to cloud servers. This means developers cannot intercept sensitive content such as users' text messages, emails, or medical alerts through remote nodes, ensuring physical isolation of privacy.
Apple emphasized that this sharing system is implemented at the system level, and users have the highest level of final decision-making power. As long as users turn off the switch in the system settings, no third-party accessories can forcibly read data, thereby fully returning the choice to consumers.
From the perspective of AIbase, Apple's move is a high-stakes balancing act between compliance and privacy. In the regulatory context of having to open up the ecosystem, by setting a "no AI training" red line, Apple is trying to maintain its core value as a "gatekeeper" of user data.
For developers, this extremely detailed compliance framework means the space for "technical arbitrage" has been greatly reduced. In the privacy environment of 2026, how to enhance the intelligent interaction experience of accessories without crossing the red line will become a new challenge for hardware manufacturers.
