How to Automatically Delete Siri Conversations: iOS 27 Guide

Apple's redesigned Siri app works like other AI chat apps, keeping a running log of conversations instead of clearing them after each session. Testing from iDownloadBlog found the app keeps a permanent archive of conversations by default, one that stays in place until someone changes it. For iPhone, iPad, and Mac owners running the update, learning how to automatically delete Siri conversations is the reported way to keep that history from growing without limit.

Access depends on hardware and region before anything else. The redesigned Siri app requires iOS 27, iPadOS 27, or macOS 27 Golden Gate on a device that supports Apple Intelligence, reportedly starting at the iPhone 15 Pro, and BGR reports the new Siri AI hasn't reached Europe yet (per BGR). Where the feature has rolled out, the Keep Conversations menu offers three choices: Forever, the reported default, alongside 1 Year and 30 Days.

The finding comes from one outlet's hands-on testing, not Apple's own documentation of what the app stores. Apple's support page explains the separate analytics opt-in covered later in this piece, but it doesn't describe the scope of the Siri app's visible chat history, leaving that detail undocumented by the company itself.

The same testing found that most everyday Siri requests made outside the dedicated app, including a basic weather check, still show up inside the Siri app's history. Narrow exceptions apply: setting a timer, setting an alarm, placing a call, or sending a text don't appear to get logged, per iDownloadBlog.

Who can set a Siri conversation deletion schedule right now

The Keep Conversations option showed up in testing only inside the redesigned Siri app, tied to iOS 27, iPadOS 27, or macOS 27 Golden Gate on Apple Intelligence-compatible hardware (per BGR). The setting may not appear on devices that don't support Apple Intelligence or haven't received the redesigned Siri experience.

The Europe exclusion BGR reports isn't broken down further in the available reporting, which doesn't specify whether it's enforced by account region, device locale, or some other mechanism. That makes it a regional limitation worth verifying on a given device rather than a confirmed account-level toggle.

If Settings > Siri doesn't show Keep Conversations, three things are worth checking before assuming the toggle is bugged: the installed OS version, whether the device supports Apple Intelligence, and whether the new Siri app has reached the account's region.

How to automatically delete Siri conversations on iPhone, iPad, and Mac

On iPhone or iPad, the path is Settings > Siri > Keep Conversations, then a choice between 30 Days or 1 Year, per iDownloadBlog. On Mac, it's System Settings, then Siri in the sidebar, then Keep Conversations, with the same two choices. iDownloadBlog's own steps label the toggle "Keep Conversation" on iPhone and "Keep Conversations" on Mac, so the wording may vary slightly depending on platform.

Choosing either auto-delete option has an immediate and irreversible effect. Every existing chat older than the selected threshold gets deleted right away, and that deletion can't be undone. From that point forward, the app keeps removing chats once they cross the same age, per iDownloadBlog.

BGR's reporting also covers manual deletion for anything that hasn't aged out yet: swiping on a chat inside the Siri app removes it individually, and tapping the menu button, choosing Select, and marking several chats clears them at once (per BGR).

The shortest option still keeps 30 days of history. Nothing in the current Keep Conversations menu deletes a chat the moment it happens.

What the retention window deletes, and what it leaves behind

Keep Conversations governs the Siri app's visible chat history. Per iDownloadBlog's testing, that includes both conversations started inside the app and ordinary Siri requests made elsewhere, since both reportedly feed the same log.

iCloud sync adds a separate wrinkle. iDownloadBlog's steps show turning this off under Settings > Apple Account > iCloud > See All > Siri, then disabling sync for that device, with the option to keep or delete the existing local conversations at that point. According to the outlet's testing, deleting history on a device with sync off only clears that device's local copy, leaving other synced devices and iCloud untouched. The available reporting doesn't confirm whether the Keep Conversations preference itself carries across an Apple Account automatically, so checking the setting on each device in use is the safer approach rather than assuming one change covers everything.

A broader action called Delete Data From iCloud sits a few taps further in. On iPhone or iPad, iDownloadBlog's steps run through Settings > Apple Account > iCloud > See All > Siri > Manage Storage > Delete Data From iCloud. On Mac, the equivalent path is System Settings > Apple Account > iCloud > Manage > Siri > Delete Data From iCloud. This clears Siri data stored in iCloud, a different and larger scope than simply trimming the app's visible history, and it can also disrupt HomePod voice recognition and personalized results, such as pulling up the correct household member's calendar, per iDownloadBlog.

Apple has separately said that request-processing data stays on-device where possible, and that anything routed through Private Cloud Compute gets discarded once a response is delivered, a claim BGR relays from the company. That statement describes how Siri handles a request in the moment; it's a different question from whether a finished chat gets saved to the Siri app's history or synced to iCloud, which is what Keep Conversations and the Delete Data From iCloud option actually address.

Siri AI conversation privacy settings beyond chat history

Deleting chat history or shortening the retention window doesn't touch a separate setting called Improve Siri & Apple Intelligence (or Improve Siri & Dictation), found under Settings > Privacy & Security > Analytics & Improvements. Opting in lets Apple store and review samples of audio and transcripts, and for the Apple Intelligence option, use that data to train foundation models, per Apple Support. Only Apple employees review the audio recordings themselves, though a subset of non-audio data samples may go to outside graders, and Apple says the information ties to a random device identifier rather than an Apple Account, isn't used to build marketing profiles, and isn't sold.

That toggle doesn't move based on whatever retention window gets set for chat history. It has to be checked on its own.

Siri's ChatGPT extension is a separate data channel entirely. BGR's reporting directs users to a toggle inside Siri's settings to turn the extension off, and notes that OpenAI could collect relevant information when someone signs in with ChatGPT credentials (per BGR). The reporting doesn't name an exact menu label for that control, so it's a matter of locating the ChatGPT extension option within Siri settings rather than following one fixed sequence of taps.

Apple's handling of Siri data has drawn scrutiny before. The company agreed to a $95 million settlement in 2025 over allegations that Siri recorded private conversations without disclosure, while denying the allegations as part of that settlement, per Scientific American. That case centered on undisclosed human review of recordings, a different issue from the chat-retention setting covered here.

What to do now

Setting Keep Conversations to 30 Days, or 1 Year for a longer buffer, is the reported way to stop Siri's chat log from accumulating indefinitely, and that setting needs checking on each device since sync status doesn't guarantee it carries everywhere. Anything sensitive should be deleted by hand before it ages out, since auto-deletion past the chosen threshold can't be reversed, and the Improve Siri & Apple Intelligence toggle along with the ChatGPT extension call for separate review, since neither one changes based on how long chat history sticks around.
