What are 'cookies'?
'Cookies' are small text files that are stored by the browser (e.g. Internet Explorer or Safari) on your computer or mobile phone. They allow websites to store such things as user preferences. You can think of cookies as providing a "memory" for the website, enabling it to recognise a user and respond appropriately.
Anonymous analytics cookies:
Every time a user visits our website, web analytics software provided by a third party 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 unique users we have, and how often they visit the site. These cookies cannot be used to identify individuals; they are used for statistical purposes only.
Other third party cookies
On some pages of this site, third parties may also set their own anonymous cookies, for the purposes of tracking the success of their application, or customising the application for you. Because of how cookies work, this site cannot access these cookies, nor can the third parties access the data in cookies used by this site.
For example, when you share an article using a social media sharing button on the site, the social network that has created the button will record that you have done this.
