Archive: Chrome OS Privacy Notice

May 3, 2011

The Google Privacy Policy describes how we treat personal information when you use Google's products and services, including information provided when you use Chrome OS.

Chrome OS is built around Google Chrome, the web browser from Google. Nearly all of your interactions in Chrome OS happen inside this browser, and are covered by the same privacy safeguards that we created for Google Chrome. You can read the Google Chrome Privacy Notice here.

In addition, the following describes some additional privacy practices that are specific to Chrome OS.

Information we collect and how we use it

Chrome OS will store your browser setting information, such as your bookmark data, on Google's servers in association with your Google Account. You can control what types of information are synchronized in this way from the settings menu in Chrome OS, and from your Google Account dashboard. Information stored with your Google Account is protected by the Google Privacy Policy. We need to store this information so that you can benefit from the "stateless" nature of Chrome OS, and use it across multiple devices.

Chrome OS will send usage statistics and crash reports to Google unless you have disabled this feature. You can disable the transmission of usage statistics and crash reports at any time from the settings menu in Chrome OS. Usage statistics and crash reports help us diagnose problems with Chrome OS and help us improve the product. Chrome OS tries to avoid sending information that identifies you personally. Crash reports, however, can contain information from files, applications and services that were running at the time of a malfunction. We may share with third parties certain aggregated, non-personal information we derive from our analysis, such as how frequently certain types of crashes occur.

Like Google Chrome, when you use Chrome OS information about your browsing history will be stored on your device (see the section entitled "Information stored on your computer when you use Google Chrome" in the Google Chrome Privacy Notice). In addition to using incognito window, the use of Guest sessions will also restrict the recording of this information, and you can delete it at any time.


Chrome OS allows you (or other users) to access the device in Guest sessions. This is the Chrome OS equivalent of incognito window in Google Chrome, and is always available to you. This mode allows you to use Chrome OS in a mode where no personal information is sent to Google.

Many of the features of Google Chrome such as phishing and malware protection, DNS pre-fetching, suggest and translate are enabled by default in Chrome OS. These features can be disabled from the settings menu in Chrome OS.
