How to Limit Siri App Access in iOS 27.2: Step-by-Step

Apple just gave iPhone owners a direct way to control Siri AI's access to apps, and it's a fix years in the making. iOS 27.2 adds a new Settings > Siri > Excluded Apps menu that lets users block Siri's AI engine from reading specific apps, replacing a multi-toggle setup that previously required disabling several settings per app or turning off Siri AI entirely (BGR, yesterday; EFF, 2 days ago).

The timing makes sense once you look at what Siri AI can actually touch. It now pulls from Messages content, Photos, Safari history, calendar attendees, voicemails, and conversations from the past week to answer questions across apps (Apple Newsroom, 4 days ago; TechCrunch, 3 days ago).

Before hunting down the setting, check eligibility. Siri AI is still beta software that requires an Apple Intelligence-enabled device set to a supported language, limited to English, French, Japanese, Korean, Portuguese, or Spanish, and it remains unavailable on iOS in the EU (Apple Newsroom, 4 days ago).

EFF argues the new controls answer a request from its Encrypt It Already campaign earlier this year and calls the setup far clearer than the confusing per-app toggles iOS 27 launched with.

What Siri personal context can reach on your iPhone

Siri AI can search Messages for specific mentions and photos shared in that app, identify people or objects described in Photos, and search Safari browsing history and Reading List items (BGR, yesterday).

Apple and TechCrunch both confirm the assistant also pulls from calendar attendees and voicemails, and it can recall details from conversations held within the past week (TechCrunch, 3 days ago; BGR, yesterday).

Onscreen awareness lets Siri answer questions about whatever is currently displayed, and expanded systemwide app actions let it draft emails or edit photos without opening the app first (Apple Newsroom, 4 days ago).

Third-party access still depends on developer support. If an app hasn't added Siri AI integration, its contents stay out of reach except through onscreen awareness, which works differently than targeted data access (EFF, 6 weeks ago).

That dependency is exactly why app-level controls matter now. Siri's reach extends well past voice commands into some of the most sensitive data stored on a phone, and app-by-app exclusion is the most consistent way to draw a line.

How to limit Siri app access in iOS 27.2

Before 27.2, blocking Siri from an app meant toggling several settings or disabling Siri AI outright. The new Excluded Apps list condenses that into one menu, giving users a single place to manage Siri personal context permissions instead of hunting through separate screens (EFF, 2 days ago).

To block Siri from accessing app data on a specific app, both BGR and EFF confirm the same steps:

1. Open Settings and tap Siri.
2. Tap Excluded Apps.
3. Tap Add Apps.
4. Select the apps you want blocked.
5. Tap the checkmark in the top-right corner to confirm.

Removing an app from the list follows a similar pattern:

1. Open Excluded Apps again.
2. Tap Edit.
3. Tap the red circle next to the app.
4. Tap Delete.
5. Tap the checkmark to confirm.

Excluded apps can also be left out of Search and suggestions, not just Siri AI queries, according to BGR's testing of the feature (BGR, yesterday).

What you might lose when you exclude an app

Excluding Messages means Siri can no longer read or respond to texts in that app, and excluding Signal stops Siri from interpreting anything inside it (EFF, 2 days ago).

Onscreen awareness also stops working for apps on the exclusion list, so asking Siri about whatever is currently on screen inside a blocked app will not work (EFF, 2 days ago).

BGR notes the trade-offs extend to everyday convenience too: excluding Mail may affect the ability to have Siri draft emails, and excluding WhatsApp may affect the ability to send messages there with a prompt or voice command (BGR, yesterday).

EFF frames the lost functionality as proof the setting works, not a flaw, arguing that users should be able to make that trade-off deliberately rather than have it made for them by default.

That reframes the decision. It's less "turn privacy on" and more a question of which conveniences are worth giving up, app by app.

Siri privacy settings for individual apps, and what else to check

Excluded Apps controls what Siri can read, but it doesn't control whether interactions feed Apple's model training. Users can opt out of that separately by disabling "Improve Siri & Dictation" under Settings > Privacy & Security > Analytics & Improvements (EFF, 6 weeks ago).

Readers who want nothing to do with Siri AI can revert to Siri Classic through Settings > Screen Time > Content & Privacy Restrictions > Siri > Allowed Siri Version (EFF, 6 weeks ago).

EFF compared the setup favorably to Android, noting that Gemini lacks a per-app toggle for screen context and instead relies on a Connected Apps setup buried under Google's Personal Intelligence settings (EFF, 2 days ago).

One caveat worth flagging: EFF says users cannot tell from an individual Siri request whether it was processed on-device or routed through Apple's Private Cloud Compute servers (EFF, 2 days ago). That doesn't mean exclusion fails to work, but Apple's documentation reviewed for this article doesn't spell out every path data could take once an app is excluded, so treat the setting as a meaningful control rather than an airtight guarantee.

Messaging apps carrying sensitive conversations, such as Signal or WhatsApp, are the clearest early candidates for exclusion given how directly Siri reads inside them once an app adds support. Anyone deciding what to add to the list should start there and expand based on comfort level with the rest.

Check these limits before you rely on it

Apple hasn't made Siri AI universally available yet. It remains beta software limited to Apple Intelligence-capable devices, supports English, French, Japanese, Korean, Portuguese, and Spanish, and is still unavailable on iOS in the EU (Apple Newsroom, 4 days ago). An earlier Apple announcement adds that the assistant is also absent from iOS in China while the company works through regulatory requirements there (Apple Newsroom, earlier this month).

Some server-side Siri AI features also carry daily usage limits that vary by request complexity and system demand, and Apple says expanded access will eventually require payment (Apple Newsroom, 4 days ago).

Adoption is still catching up, too. Apple says, as reported by TechCrunch, that about 80% of iPhone owners are still running iOS 26, which suggests most people won't see the Excluded Apps setting until they update (TechCrunch, 3 days ago).

Check the iOS version and device compatibility first. If eligible, update to 27.2, open Settings > Siri > Excluded Apps, and go through it app by app rather than treating it as one blanket privacy switch. Exclude only the apps whose Siri AI conveniences are worth losing, then open each excluded app once to confirm Siri no longer responds to questions about it.
