Chrome Deleted Its Privacy Promise for On-Device AI – Here’s What You Can Do

If you’ve been relying on Chrome’s “on-device AI” features thinking they keep your data away from Google’s servers, you might want to reconsider. In early May 2026, Google removed a key line from its support pages that had previously promised: “On-device AI does not send data to Google servers.” The change was first reported by Decrypt and later confirmed by GIGAZINE. At the same time, users discovered that Chrome was silently downloading a 4 GB AI model that reappears even after deletion.

Here’s what happened, why it matters, and what you can do to protect your privacy today.

What Happened

Until recently, Google’s documentation for Chrome’s built-in AI features contained a straightforward privacy assurance: the AI processing happens entirely on your device and no data leaves your computer. That statement is now gone.

Several security researchers and outlets noticed the deletion in the second week of May 2026. The original phrasing was present in a support article explaining how Chrome’s local AI features work—features like smart tab grouping, writing assistance, and image captioning. Google did not issue a public announcement about the change.

Around the same time, Decrypt also reported that Chrome was automatically downloading a large AI model (roughly 4 GB) onto users’ machines. Even when users deleted the model, Chrome would re-download it on the next update or browser restart, raising questions about consent and control.

Google has not officially commented on either the removal of the privacy claim or the model’s behavior.

Why It Matters

The removal of that promise does not prove that Google is now sending your data to its servers. But it removes a clear guarantee that many users depended on. If the AI model is no longer fully on-device, any data processed through it—such as text you type, web pages you view, or actions you take—could potentially be sent back to Google for further processing, improvement of the model, or other uses.

The fact that the model re-downloads after deletion also raises concerns about transparency. Users who deliberately remove the model may still have it reinstalled without their knowledge, and that reinstallation could happen in the background without notification.

In the broader context of browser-based AI, this sets a precedent: features marketed as “on-device” may not stay that way, and companies can quietly adjust their privacy policies without alerting users.

What You Can Do

If you want to limit Chrome’s AI capabilities and reduce the chance of data leaving your machine, here are concrete steps:

  1. Disable AI features in Chrome settings. Go to chrome://settings/ai and turn off all toggles under “AI features.” This includes smart suggestions, tab organization, and writing help. Note that this may not prevent the model from being downloaded or running in the background.

  2. Delete the AI model from disk. The model is stored in Chrome’s profile folder. On Windows, it’s usually at %LOCALAPPDATA%\Google\Chrome\User Data\AI. On macOS, look under ~/Library/Application Support/Google/Chrome/AI. Deleting the folder will remove the model, but Chrome may re-download it. To prevent that, you need to disable the feature and potentially block the download via system firewall or parental control software.

  3. Switch to a more privacy-focused browser. Alternatives like Firefox, Brave, or Ungoogled Chromium offer similar browsing experiences without Google’s AI integration. Firefox, for example, has its own AI features but they are opt-in and clearly explained. Brave blocks many trackers by default and gives you granular control over AI components.

  4. Use browser-level privacy extensions. Tools like uBlock Origin or Privacy Badger can block connections to Google’s AI endpoints, but they are not a perfect solution if the model is already embedded.

  5. Stay informed. Keep an eye on Chrome’s official changelogs and privacy announcements. Independent tech news and security forums often catch these changes faster than official channels.
