How to Limit Siri’s Access to iPhone Apps

Digital Information World says the redesigned Siri combines the assistant and Spotlight in one interface.[1] By default, Siri searches Apple apps including Notes, Messages and email.[1] The article also says Siri can summarize what it thinks a photo shows when a user asks about a photo sent in Apple Messages.[1] Access to third-party apps is different: it depends on whether developers choose to add support.[1] If a developer has not added support, Siri cannot access that app’s contents unless the content is shared through on-screen awareness.[1]

Siri sometimes uses Private Cloud Compute, which sends data off the device to a cloud server.[1] Digital Information World says users receive no immediate visual indication when data leaves the device for that processing.[1] Apple says data sent to Private Cloud Compute is not stored after processing.[1] The Electronic Frontier Foundation, however, says sending end-to-end-encrypted iCloud data off-device and into the cloud changes the user’s risk assessment, regardless of privacy promises.[1] These are distinct points: Apple describes its handling of the data, while the EFF highlights the significance of off-device processing.

To manage Siri’s access to a particular app, Digital Information World directs users to Settings > Apps > the selected app > Search.[1] The article says disabling that setting prevents Siri from surfacing details from the selected app.[1] For Messages, disabling “Show Content in Search” prevents Siri from reading conversations.[1] Users who want a broader change can turn off Siri through Settings > Siri > “Turn Off Siri,” according to the article.[1] These controls let users choose between limiting an individual app and disabling Siri entirely.

Digital Information World says Apple’s AI features require an iPhone 15 Pro or Pro Max, or any iPhone 16 or newer.[1] It also reports that Siri AI is available only in English and is not available worldwide.[1] BigGo Finance reports that access to the new Siri requires joining a waitlist.[2] BigGo says the assistant can retrieve details from Notes and Messages, summarize message threads, and surface calendar and email information ahead of meetings.[2] It also says the controls do not grant Siri additional access to app content.[2]
