What are cookies?

A cookie is a small text file that a website saves onyour computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) over a period of time, so you don't have to keep re-entering them whenever you come back to the site or browse from one page to another.

How do we use cookies?

Also, some videos embedded in our pages use a cookie to anonymously gather statistics on how you got there and what videos you visited.

Enabling these cookies is not strictly necessary for the website to work but it will provide you with a better browsing experience. You can delete or block these cookies, but if you do that some features of this site may not work as intended.

The cookie-related information is not used to identify you personally and the pattern data is fully under our control. These cookies are not used for any purpose other than those described here.

Preferences

These cookies allow our websites to remember information that changes the way the site behaves or looks, such as your preferred language or the region you are in. For instance, by remembering your region, a website may be able to provide you with local weather reports or traffic news. These cookies can also assist you in changing text size, font and other parts of web pages that you can personalize.

Loss of the information stored in a preference cookie may make the website experience less functional but should not prevent it from working.

Most Google users will have a preferences cookie called ‘PREF’ in their browsers. A browser sends this cookie with requests to Google’s sites. The PREF cookie may store your preferences and other information, in particular your preferred language (e.g. English), how many search results you wish to have shown per page (e.g. 10 or 20), and whether or not you wish to have Google’s SafeSearch filter turned on.

Security

We use security cookies to authenticate users, prevent fraudulent use of login credentials, and protect user data from unauthorized parties.

For example, we use cookies called ‘SID’ and ‘HSID’ which contain digitally signed and encrypted records of a user’s Google account ID and most recent sign-in time. The combination of these two cookies allows us to block many types of attack, such as attempts to steal the content of forms that you complete on web pages.

Processes

Process cookies help make the website work and deliver services that the website visitor expects, like navigating around web pages or accessing secure areas of the website. Without these cookies, the website cannot function properly.

For example, we use a cookie called ‘lbcs’ which makes it possible for Google Docs to open many Docs in one browser. Blocking this cookie would prevent Google Docs from operating correctly.

Manage your preferences

Most web browsers allow you to manage your cookie preferences. You can set your browser to refuse cookies, or delete certain cookies. Generally you should also be able manage similar technologies in the same way that you manage cookies – using your browsers preferences.
