Chrome Quietly Removes Privacy Promise About On-Device AI — Here’s What to Do

If you’ve been using Chrome’s newer AI features under the assumption that everything stays on your device, a recent change might give you pause. Around the start of May 2026, Google removed a key statement from Chrome’s settings page that had explicitly promised on-device AI does not send data to Google servers. At the same time, separate reports indicate that Chrome is installing a large AI model (roughly 4 GB) that reappears even after you delete it.

The news has been covered by several outlets, including Decrypt and Yahoo Tech, and a Japanese tech site (GIGAZINE) confirmed the removal. Google has not issued an official statement as of this writing, so some details remain uncertain. But the implications for everyday users are clear enough that it’s worth understanding what changed and how to protect your privacy.

What Happened

Previously, within Chrome’s AI settings, there was a line that read something like: “On-device AI processes data locally and does not send any data to Google servers.” That wording has now disappeared. The page still describes the AI features, but the explicit privacy guarantee is gone.

Separately, researchers and users have noticed that Chrome is downloading a machine learning model—about 4 GB in size—onto computers where certain AI features are enabled. Even if you manually delete that model, it can reappear after a browser restart or update. This behavior was first highlighted by Decrypt in an article titled “Chrome Is Quietly Installing a 4GB AI Model on Your Computer—And Putting It Back If You Delete It.”

Taken together, these two developments suggest a change in how Chrome handles AI data. Whether the model itself is phoning home to Google is not confirmed, but the removal of the privacy promise weakens the assurance that no data leaves your machine.

Why It Matters for Your Privacy

For years, “on-device processing” has been sold as a privacy-friendly alternative to cloud-based AI. Features like smart text selection, tab grouping suggestions, or experimental writing assistants were supposed to run entirely on your hardware. That meant no data exposure to servers, no logs attached to your account, and no risk of your browsing habits being used for training.

If that claim is no longer true—or if users can’t verify it—the trust built around Chrome’s privacy features erodes. The 4 GB model being persistently reinstalled also raises questions about transparency. Users who delete the model may be unaware that it will come back, potentially consuming disk space and bandwidth without clear consent.

There’s also a broader concern: once data leaves your device, it becomes harder to control how it’s stored, shared, or used by third parties. Even if Google’s intentions are benign, the removal of the explicit promise creates an opening for data collection that didn’t exist before.

How to Check and Protect Yourself

If you want to see whether the large AI model is on your system, you can look for a folder named something like OnDeviceModelExecution or AI in Chrome’s user data directory. The exact path varies by operating system:

  • Windows: %LOCALAPPDATA%\Google\Chrome\User Data\OnDeviceModelExecution
  • macOS: ~/Library/Application Support/Google/Chrome/OnDeviceModelExecution
  • Linux: ~/.config/google-chrome/OnDeviceModelExecution

If the folder exists and contains files totaling several gigabytes, the model is installed. You can delete the folder, but as noted, it may return. To prevent reinstallation, you’ll need to disable the related AI features in Chrome’s settings.

Steps to Disable On-Device AI in Chrome

  1. Open Chrome and go to chrome://settings.
  2. Click Advanced (or Privacy and security depending on your version).
  3. Look for a section labeled AI or Experimental AI. (The exact name may vary.)
  4. Turn off any toggles for features like “Try out experimental AI,” “Help me write,” or “Tab organization suggestions.”
  5. Restart the browser.

Disabling these features should stop the model from being downloaded or reinstalled. If you’re not using the AI tools anyway, there’s no downside.

What This Means Going Forward

Google has not commented on the removal of the privacy promise or the persistent model installation. Until it does, users have to decide how much trust to place in Chrome’s current AI features. For privacy-sensitive tasks, you may want to use an alternative browser—Firefox, Brave, or Vivaldi, for example—that does not include similar AI capabilities.

If you stick with Chrome, at least you now know that the old guarantee is gone. Keep an eye on Chrome’s release notes and settings pages for any new disclosures about data handling. And remember: if a feature is labeled “on-device” but the company removes the fine-print promise, it’s worth treating that label with skepticism.
