A cookie (also known as an HTTP cookie, web cookie, or browser cookie) is a small piece of data sent from a website and stored in a user’s web browser while the user is browsing that website. Every time the user loads the website, the browser sends the cookie back to the server to notify the website of the user’s previous activity. Cookies were designed to be a reliable mechanism for websites to remember useful information (such as items in a shopping cart) or to record the user’s browsing activity (including clicking particular buttons, logging in or recording which pages were visited by the user as far back as months or years ago).
A visit to a page on this website may generate the following types of cookie:
Anonymous analytics cookies:
Every time a user visits the website, software provided by another organisation generates an ‘anonymous analytics cookie’. These cookies can tell us whether or not you have visited the site before. Your browser will tell us if you have these cookies and, if you don’t, we generate new ones. This allows us to track how many individual users we have and how often they visit the site. Unless you are signed in to this website, we cannot use these cookies to identify individuals. We use them to gather statistics: for example, the number of visits to a page. If you are logged in, we will also know the details you gave to us for this, such as your username and email address.
(For example, Google Analytics)
When you register with this website, we generate cookies that let us know whether you are signed in or not. Our servers use these cookies to work out which account you are signed in with and whether you are allowed access to a particular service.
Third party advertising cookies
Some of the advertisements you see on this website are provided by other organisations. These organisations can use their own anonymous cookies to track how many people have seen a particular ad, or to track how many people have seen it more than once.
The companies that generate these cookies have their own privacy policies, and we have no access to read or write these cookies. These organizations may use their cookies to anonymously target advertising to you on other websites, based on your visit to this website.
(For example, OpenX)
Other third party cookies
On some pages of our website, other organisations may also set their own anonymous cookies. They do this to track the success of their application, or to customise the application for you. Because of how cookies work, our website cannot access these cookies, nor can the other organisation access the data in cookies we use on our website.
For example, when you share an article using a social media sharing button (for example, Facebook) on this website, the social network that has created the button will record that you have done this.
How do I turn cookies off?
