How to stop iOS 27’s new Siri from reaching into your apps and data

Apple’s more capable Siri can use personal data, inspect screens and act across compatible apps, but iPhone users can restrict its access or turn the AI assistant off altogether.

Apple’s new Siri AI, introduced in iOS 27, is designed to behave more like an assistant than a simple voice command tool. According to BGR’s report, it can draw on personal data, interact with compatible third-party apps, inspect what is on the screen and complete tasks on the user’s behalf. Apple says the system keeps personal information private even when it uses cloud processing for more demanding requests, but the depth of access may still concern users who do not want an AI assistant reaching into their device history.

That concern is not unwarranted, because Apple’s own support material shows there are several ways to narrow Siri’s reach. On an iPhone running iOS 27, users can go to Settings, open Siri and then App Access, choose a specific app and switch off “Learn from this App”. Apple also says the same control can be found by opening an app’s settings directly under Apps and then disabling the same option.

There are broader controls as well. BGR notes that users can disable “Suggest App”, which is used for actions such as turning an email into a calendar entry, although Apple’s support page explains that these suggestions rely on on-device processing rather than sending the information elsewhere. Apple also provides a switch for “Automatic Visual Look Up”, a feature that can identify objects and places in screenshots. Users who want the most restrictive setup can turn Siri off entirely from the Siri menu.

Other guides have pointed to further privacy steps. Gadget Hacks says users can reduce Siri’s access to content inside apps by changing search settings for individual applications, while the Electronic Frontier Foundation has advised users to review options for limiting what Siri can read, declining training-related data collection and, where preferred, reverting to the classic Siri experience. For families, Mac Observer reports that Screen Time restrictions can also be used to block Siri AI or limit its functions on managed devices.

The wider rollout is also shaped by regulation. In June 2026, Apple said Siri AI would not launch in the European Union with iOS 27 and iPadOS 27 because of the Digital Markets Act, although it said the feature would still be available on macOS 27 and visionOS 27. That makes the privacy controls especially relevant for users in markets where the assistant is available, since Apple’s new approach gives Siri far deeper access to data and app activity than the older version.
