Information Google receives when you use Google Chrome
You do not need to provide any personally identifying information in order to download and use Google Chrome. When you download Google Chrome or use it to contact Google’s servers, Google receives only standard log information including your machine’s IP address and one or more cookies. You can configure Google Chrome to not send cookies to Google or other sites as explained here.
In addition, some Google Chrome features send limited additional information to Google:
- When you type URLs or queries in the address bar, the letters you type are sent to Google so the Suggest feature can automatically recommend terms or URLs you may be looking for. If you choose to share usage statistics with Google and you accept a suggested query or URL, Google Chrome will send that information to Google as well. You can disable this feature as explained here.
- If you navigate to a URL that does not exist, Google Chrome may send the URL to Google so we can help you find the URL you were looking for. You can disable this feature as explained here.
- Google Chrome's SafeBrowsing feature periodically contacts Google's servers to download the most recent list of known phishing and malware sites. When you visit a site that we think is a phishing or malware site, your browser will send Google a hashed, partial copy of the site's URL so that we can send more information about the risky URL. Google cannot determine the real URL you are visiting solely from this information. In addition, if you have chosen to share usage statistics with Google and you visit a site that we think could be a phishing or malware site, certain other data will be shared with Google, including the full URL that you visited, the "referer" header sent to that page, and the URL that matched the Google Safe Browsing malware list. You can disable the Google Safe Browsing service as described here, or you can opt-out of sharing usage statistics with Google as described here. More information about how this works is here.
- Your copy of Google Chrome includes a temporary randomly-generated installation number which will be sent to Google when you install and first use Google Chrome. The temporary number will be promptly deleted when Google Chrome automatically checks for updates. If you received your copy of Google Chrome as part of a promotional campaign, your copy may generate a unique promotion number which is sent to Google only when you first run and first use Google Chrome.
- You may choose Google as your search engine using Google Chrome, and you may also use Google Chrome to access other Google services such as Gmail. The Privacy Policies of Gmail or other services apply when you access them, no matter which browser you use. Using Google Chrome to connect to Google services will not cause Google to receive any special or additional personally identifying information about you.
- If you use the Translate feature of Google Chrome, it will send the text you choose to be translated to Google for translation.
- If you use Google Chrome’s location feature which allows you to share your location with any site, Google Chrome will send local network information to Google Location Services to get an estimated location. The local network information includes, depending on the capabilities of your device, information about the wifi routers closest to you, cell ids of the cell towers closest to you, the strength of your wifi or cell signal, and information about your device such as your device’s IP address. We use the information to process the location request and to operate, support, and improve the overall quality of Google Chrome and Google Location Services. Information collected above will be anonymized and aggregated before being used by Google to develop new features or products and services, or to improve the overall quality of any of Google’s other products and services.
- You may choose to send usage statistics and crash reports to Google. The usage statistics and crash reports help us diagnose problems with the browser, understand how users interact with the browser, and help us improve its performance. Google Chrome 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.
Information website operators receive when you visit a site using Google Chrome
Sites that you visit using Google Chrome will automatically receive standard log information similar to that received by Google. These sites may also set their own cookies or use web storage on your machine. You can restrict cookies by setting your preferences in the Google Chrome Options menu. If you use Google Chrome in incognito mode, it will not transmit any pre-existing cookies to sites that you visit. Sites may deposit new cookies on your machine while you are in incognito mode, however. These cookies will be temporarily stored and transmitted to sites while you remain in incognito mode. They will be deleted when you close the browser or return to normal browsing mode.
If you opt-in to using Google Chrome’s location feature, this service allows you to share your location with a site. We will not allow a site to access your location without your permission. If the site is a non-Google website, we do not have control over the website or its privacy practices. Please carefully consider any website’s privacy practices before consenting to share your location with that website.
Information stored on your computer when you use Google Chrome
Google Chrome records useful information about your browsing history on your own computer. This includes:
- Basic browsing history information: the URLs of pages that you visit, a cache file of text from those pages, and a list of some IP addresses linked from pages that you visit.
- A searchable index of most pages you visit (except for secure pages with "https" web addresses, such as some bank pages)
- Thumbnail-sized screenshots of most pages you visit
- Cookies or web storage data deposited on your machine by websites you visit
- A record of downloads you have made from websites
You can delete all or portions of this history at any time as explained in the FAQ.
You can also limit the information Google Chrome saves on your computer by using incognito mode. In this mode, the browser will not store basic browsing history information such as URLs, cached page text, or IP addresses of pages linked from the websites you visit. It will also not store snapshots of pages that you visit or keep a record of your downloads. (This information could still be stored elsewhere on your computer, though.) New cookies received in incognito mode will not be saved after you close your browser or return to normal browsing mode. You can see when you are in incognito mode because the incognito icon appears in the top corner of your browser; in some cases the border of your browser window may also change color.
When you make changes to your browser configuration, such as by bookmarking a web page or changing your settings, this information is also saved. These changes are not affected by incognito mode.
You can choose to have Google Chrome save your passwords for specific websites. Stored passwords can be reviewed in the Personal Stuff tab of the Options dialog box.
Information relating to using extensions on Google Chrome
If you install an extension on Google Chrome, it can store data locally and send any data it has permission to access to any third party server that it has permission to communicate with. Therefore you should be very careful that you know and trust the developer of the extension. When you download an extension, you will be notified of the permissions that you are giving the extension. Google Chrome saves a list of all your extensions on your computer, together with the URL for updates and the category of permissions required by the extension to operate. Periodically, Google Chrome will use this information to check for updates to the extensions and to download and install updates automatically. In addition, Google Chrome will store a list of extensions known to be harmful or illegal, for use in the event that it is necessary to disable or remove an extension from your computer. Periodically, Google Chrome will download or update this list.
If you use extensions hosted by Google, your browser will send us one or more unique information numbers when you first install the extension, when Google Chrome checks for updates for the extension, and when you uninstall the extension. We will use this information to track usage data about the extension on the extensions gallery and to rank the popularity of extensions. We will not use this information to identify you or associate this information with your personal information.
Information that Google receives when you use Google Chrome is processed in order to operate and improve Google Chrome and other Google services. Information that other website operators receive is subject to the privacy polices of those websites. Google Chrome stores information on your machine in order to improve the browser’s performance and provide you with features, such the option to review snapshots from pages you have visited.
Google adheres to the US Safe Harbor privacy principles. For more information about the Safe Harbor framework or our registration, see the Department of Commerce's web site.
