Apple's new Siri AI, released with iOS 27, offers smarter, more personalized responses but requires extensive data access. It uses App Intents to scan through your Apple apps and supported third-party apps, leveraging on-device models and Apple's Private Cloud Compute (PCC) for processing. While Apple claims it doesn't store data post-processing, users may still have privacy concerns.
To limit Siri's access, open Settings, go to Apps, select the desired app, tap Search, and toggle off "Show Content in Search." This prevents Siri from pulling information from that app, even upon direct request. Additionally, Siri can read screenshots and images via on-screen awareness, which can be helpful for accessibility or summarizing content, though this feature also raises privacy considerations. Apple has left it to developers to decide whether their apps support App Intents, meaning Siri can only access data from apps that allow iOS 27's Spotlight indexing.
Users retain control over which apps Siri can search, ensuring a balance between functionality and privacy.
