How to Set Up Auto-Deleting Chat History for Siri on iOS 27

Introduction

Apple has long positioned itself as a champion of user privacy, and with the upcoming iOS 27, it’s taking a major step to extend that ethos into the AI realm. According to a report from Bloomberg's Mark Gurman, the redesigned Siri—often described as more chatbot-like—will now offer built-in auto-deletion controls for chat histories. This means you can decide exactly how long Siri keeps a record of your conversations, with options to save chats for 30 days, one year, or forever. The move is a pointed contrast to other AI assistants that typically offer at best a temporary incognito mode. This guide will walk you through activating and customizing this auto-deleting feature, helping you balance convenience with privacy.

What You Need

An iPhone or iPad running iOS 27 or later
An active internet connection to download the update
Siri enabled (should be on by default, but double-check in Settings > Siri & Search)
An Apple ID to sign into your device (though no extra steps are required for this feature)
At least 5 minutes of free time to navigate settings

Step-by-Step Guide to Auto-Delete Siri Chat History

Step 1: Update to iOS 27

The auto-deletion setting is available only in iOS 27 and later. To check your current version, go to Settings > General > Software Update. If iOS 27 is listed, tap Download and Install. Your device will restart once the update is complete. Ensure you have enough storage and are connected to Wi-Fi for a smooth download.

Step 2: Open Siri & Search Settings

After the update, navigate to Settings on your home screen. Scroll down and tap Siri & Search. This menu houses all controls related to Siri’s behavior, including language, voice, and – now – chat history retention.

Step 3: Find the Chat History Auto-Delete Option

Within the Siri & Search menu, look for a new section labeled Chat History (or similar – the exact wording may vary in beta versions). Tap on it. You should see a description explaining that you can choose how long Siri stores your conversations. This is the feature highlighted in the Bloomberg report.

Step 4: Choose Your Retention Period

You’ll be presented with three options:

30 days – best for users who want minimal history without losing every session instantly
1 year – a middle ground useful for referencing past discussions with Siri
Forever – the same as current behavior; all chats are kept indefinitely

Select the one that fits your privacy comfort level. A confirmation pop-up may appear reminding you that auto-deletion is automatic and that once deleted, chats cannot be recovered. Tap Confirm to finalize.

Step 5: Verify the Setting Is Active

Go back to the main Siri & Search screen and then re-enter the Chat History section to ensure your chosen duration is highlighted. You can also test by asking Siri something trivial (e.g., “What’s the weather?”) and then checking if the conversation appears later in the same menu (though deletion may take effect after the time limit, not instantly).

Step 6 (Optional): Manually Delete All History Now

If you want to clear existing chats immediately, look for a Delete All Chat History button near the bottom of the Chat History settings. Tapping this will remove all past conversations irrespective of your auto-delete duration setting. Use this as a one-time reset before your chosen auto-delete schedule kicks in.

Tips for Maximizing Privacy with Siri’s Auto-Delete

Choose 30 days for peace of mind. This strikes a balance between being able to revisit recent commands and not accumulating long-term data. Apple’s servers won’t hold on to chats older than a month.
Consider 1 year if you often use Siri for reminders or research. You may want a longer window to review past questions without giving up complete indefinite storage.
Avoid “Forever” unless you trust Apple’s privacy policies completely. While Apple has a strong track record, indefinite retention increases exposure in case of a data breach or legal request.
Periodically review your chat logs. Even with auto-delete, you can manually check what Siri has stored by revisiting the Chat History menu. If you see anything sensitive, delete it manually.
Use this feature alongside other privacy controls. Consider turning off “Improve Siri & Dictation” if you don’t want Apple to use your audio samples for training. Go to Settings > Privacy & Security > Analytics & Improvements to adjust.
Remember, auto-delete only applies to Siri chat logs. It does not affect other data you share via apps or iCloud. For overall privacy, review your Apple ID > Privacy settings.
This feature underscores Apple’s differentiator. Unlike many competitors that only offer temporary incognito modes, Apple gives you persistent, automatic control. Use it to your advantage.

By following these steps, you can ensure your Siri interactions stay as private as you want them to be. The auto-delete option is a simple but powerful tool in Apple’s ongoing effort to balance AI convenience with user protection. As the AI landscape becomes more crowded, features like this may become the new standard for privacy-conscious users.
