Chrome Removes Privacy Promise for On-Device AI: What You Need to Know

If you use Google Chrome, a significant privacy-related change has flown under the radar. Multiple reports indicate that Google has deleted a long-standing privacy commitment stating that on-device AI features would process data entirely locally. At the same time, Chrome is silently installing a 4 GB AI model on many users’ computers—and it may come back even after you delete it.

Here’s what actually changed, why it matters for your privacy, and how to regain control.

What happened

Chrome’s on-device AI features were originally advertised with a clear promise: everything stays on your computer. The browser’s help documentation explicitly stated that on-device AI “does not send any data to Google or anyone else.” That wording has now been removed, as confirmed by Decrypt and Yahoo Tech in May 2026.

In parallel, Chrome has begun quietly downloading a large AI model—roughly 4 GB in size—onto users’ machines. The model is intended to power features such as smart text completion, summarization, and other generative AI tools that run (ostensibly) on your device. But the removal of the privacy promise raises questions about whether some data might eventually leave your computer, even if the processing happens locally.

Several users have reported that deleting the model file and even blocking the download via Chrome’s settings has not prevented it from reappearing after a restart or a browser update.

Why it matters

The core concern is trust. Google marketed on-device AI as a privacy advantage: you get smart features without sending your browsing activity or personal content to a server. Deleting that promise, without a clear replacement, creates uncertainty. It could mean Google is planning to shift some processing to the cloud, or to collect telemetry about what the AI model is doing on your machine.

Even if the model still runs locally today, the removal of the commitment makes it easier for Google to retroactively change how data is handled. For privacy-conscious users, this is a step backward.

There is also a practical issue: a 4 GB download is not trivial, especially on metered connections or low-storage devices. And the fact that the model can reappear after being deleted suggests that Chrome’s update mechanism treats it as essential, not optional.

What readers can do

You are not stuck with this. Chrome offers settings that allow you to disable on-device AI features. Here is how to check and adjust them.

Check if the AI model is installed

  1. Open Chrome and type chrome://components into the address bar.
  2. Look for an entry called “On-Device AI Model” or something similar. If it lists a version number and size, the model is present.

Disable on-device AI features

  1. Go to Settings > Advanced > Privacy and security > On-device AI (the exact label may vary by version).
  2. Turn off the toggle for on-device AI features. This should prevent future downloads and disable functionality that relies on the model.

If you do not see such a setting, search Chrome’s settings for “AI” or “on-device.” Older versions may place it under Experimental AI or Helpful features.

If the model returns

Some users have reported that disabling the feature is not enough—the model still gets downloaded during updates. As a more aggressive step:

  • Delete the model file manually. On Windows, it is usually in C:\Users\[YourUsername]\AppData\Local\Google\Chrome\User Data\OnDeviceAiModel. On macOS, look in ~/Library/Application Support/Google/Chrome/OnDeviceAiModel.
  • After deleting, set the folder’s permissions to read-only for your user account, which can block Chrome from writing a new model there.

Keep in mind that these workarounds may break other Chrome features that depend on the model, and future browser updates might override your changes. There is no guarantee of a permanent fix without Google rethinking its approach.

Consider alternative browsers

If privacy is a priority and you are uncomfortable with these changes, it is worth evaluating other browsers that handle AI differently. For instance, Firefox and Brave have been more explicit about keeping AI processing optional and locally sandboxed. However, the landscape is changing quickly, so verify current policies before switching.
