What is a cookie - The benefits of cookies
We use technologies like cookies and local storage to make our websites easier to use and to tailor content to be more relevant for you. This guide is designed to explain, as clearly as possible, what cookies are; the purpose of those used on our websites; and what options you have to control or delete them – if you decide you want to.
What is a cookie?
Almost every website uses cookie technology. A cookie is a small file that saves Internet settings. It gets downloaded through a browser during the first visit to a website. When you next return to the site using the same device, the browser may check to see if a related cookie is present (i.e. containing the site name) and use the data inside the cookie to send back to the site. This allows sites to recognise that the browser has visited before and, in some cases, vary the content shown to reflect that.
The benefits of cookies
Some cookies are extremely useful, because they can make the experience more user-friendly when you come back to a website you’ve visited several times previously. Provided you use the same device and browser as before, they can, for example, remember your preferences, help us to know how you use our sites, and make the content shown more relevant to your interests and needs. None of the cookies used on our websites collect information that personally identifies you.
This site uses different types of cookie.
The information generated by the cookie about your use of our website (including your IP address) will be transmitted to and stored by Google on servers in the United States. Google will use this information for the purpose of evaluating your use of our website, compiling reports on website activity and providing other services relating to website activity and internet usage.
Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google's behalf. Google undertakes not to associate your IP address with any other data held by Google.
Some third party cookies are set by services that appear on our pages. They are set by the operators of that service and are not in our control. They are set by Twitter, Facebook etc. and relate to the ability of users to share content on this site.
Controlling and deleting cookies
To control cookies, most browsers allow you to either accept or reject all cookies, only accept certain types of cookies, or prompt you each time a site wishes to save a cookie. It’s also easy to delete cookies that are already saved on your device by a browser.
The processes for controlling and deleting cookies vary depending on which browser you use. To find out how to do so with a particular browser, you can use the Help function within it or alternatively you can visit http://www.aboutcookies.org which explains, step-by-step, how to control and delete cookies in most browsers.
