Google is updating the warning on Chrome's Incognito mode to make it clear that Google and websites run by other companies can still collect your data in the web browser's semi-private mode.

The change is being made as Google prepares to settle a class-action lawsuit that accuses the firm of privacy violations related to Chrome's Incognito mode. The expanded warning was recently added to Chrome Canary, a nightly build for developers. The warning appears to directly address one of the lawsuit's complaints, that the Incognito mode's warning doesn't make it clear that Google collects data from users of the private mode.

Many tech-savvy people already know that while private modes in web browsers prevent some data from being stored on your device, they don't prevent tracking by websites or Internet service providers. But many other people may not understand exactly what Incognito mode does, so the more specific warning could help educate users.

The new warning seen in Chrome Canary when you open an incognito window says: "You've gone Incognito. Others who use this device won't see your activity, so you can browse more privately. This won't change how data is collected by websites you visit and the services they use, including Google." The wording could be interpreted to refer to Google websites and third-party websites, including third-party websites that rely on Google ad services.

The new warning was not yet in the developer, beta, and stable branches of Chrome as of today. It also wasn't in Chromium. The change to Canary was previously reported by MSPowerUser.

“Now you can browse privately”

Incognito mode in the stable version of Chrome still says: "You've gone Incognito. Now you can browse privately, and other people who use this device won't see your activity." Among other changes, the Canary warning replaces "browse privately" with "browse more privately."

The stable and Canary warnings both say that your browsing activity might still be visible to "websites you visit," "your employer or school," or "your Internet service provider." But only the Canary warning currently includes the caveat that Incognito mode "won't change how data is collected by websites you visit and the services they use, including Google."

The old and new warnings both say that Incognito mode prevents Chrome from saving your browsing history, cookies and site data, and information entered in forms, but that "downloads, bookmarks and reading list items will be saved." Both warnings link to this page, which provides more detail on Incognito mode.

We asked Google when the warning will be added to Chrome's stable channel and whether the change is mandated by or related to the pending settlement of the privacy class-action suit. Google didn't provide specific answers but offered this statement: "We're pleased to resolve this case which we've long disputed, and provide even more information to users about Incognito mode. Incognito mode in Chrome will continue to give people the choice to browse the Internet without their activity being saved to their browser or device."

The litigation in US District Court for the Northern District of California began in June 2020. On December 26, 2023, Google and the plaintiffs announced that they reached a settlement that they planned to present to the court for approval within 60 days. A jury trial was previously scheduled to begin on February 5.
