What are cookies?
A cookie is a small text file which is saved to your computer or mobile device when you visit a site. Cookies allow websites to remember your actions and preferences (e.g. login details, display language, font size and other display settings) so that you do not need to select them again when you next visit the website, or even when browsing from one page to another.
- The user's display preferences, for example contrast or character size settings
- Whether you have already responded to a pop-up survey asking you about how useful the content is, so that it is not displayed again
Moreover, some videos embedded on the pages of our website use a cookie to generate statistics, in an anonymous manner, on how you arrived at the page and which videos you watched.
It is not essential for cookies to be enabled for the website to work, but doing so will improve your browsing experience.
It is possible to delete or block cookies, but in this case some website functions may not function correctly.
Cookies are not used to identify users, and any navigation data will always remain under our control. These cookies are used only and exclusively for the purposes described above.
Do we use other cookies?
Category of Use
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 contains a unique ID Google uses to remember your preferences and other information, such as 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.
We use security cookies to authenticate users, prevent fraudulent use of login credentials, and protect user data from unauthorized parties.
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.
Sometimes an advertising cookie may be set on the domain of the site you're visiting. In the case of our DoubleClick product, a cookie named "__gads" may be set on the domain of the site you're visiting.
Other Google properties, like YouTube, may also use DoubleClick cookies to show you more relevant ads. Find out more about advertising and YouTube.
Google also uses conversion cookies, whose main purpose is to help advertisers determine how many times people who click on their ads end up purchasing their products. These cookies allow Google and the advertiser to determine that you clicked the ad and later visited the advertiser's site. Conversion cookies are not used by Google for personalized ad targeting and persist for a limited time only. These cookies are generally set in the googleadservices.com or google.com/ads domain. Data from conversion cookies may also be used in association with your Google account to connect conversion events between the various devices you use. Only anonymous conversion data gathered via these cookies are shared with advertisers.
Some of our other cookies may be used to measure conversion events as well. For example, DoubleClick and Google Analytics cookies may also be used for this purpose and be set in the domain you are visiting.
Websites often collect information about how users interact with a website. This may include the pages users visit most often and whether users get error messages from certain pages. We use these so-called ‘session state cookies’ to help us improve our services, in order to improve our users’ browsing experience. Blocking or deleting these cookies will not render the website unusable.
These cookies may also be used to anonymously measure the effectiveness of PPC (pay per click) and affiliate advertising.
For example, we use a cookie called "recently_watched_video_id_list" so that YouTube can record the videos most recently watched by a particular browser.
Google Analytics is Google’s analytics tool that helps website and app owners to understand how their visitors engage with their properties. It may use a set of cookies to collect information and report website usage statistics without personally identifying individual visitors to Google.
In addition to reporting website usage statistics, Google Analytics pixel tags can also be used, together with some of the advertising cookies described above, to help show more relevant ads on Google properties (like Google Search) and across the web.
