To make this site work properly, we sometimes place small data files called cookies on your device. Most big websites do this too.

What are cookies?

A cookie is a small text file that a website saves on your 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?

In general our cookies fall under the following four categories.

• Strictly Necessary Cookies
  These cookies are essential in order to enable you to move around the website and use its features. Without these cookies services you have asked for, such as registering for an account, cannot be provided.
• Performance Cookies
  These cookies collect information about how visitors use a website, for instance which pages visitors go to most often, and if they get error messages from web pages. These cookies don’t collect information that identifies a visitor. All information these cookies collect is aggregated and therefore anonymous. It is only used to improve how a website works.
• Functionality Cookies
  These cookies allow the website to remember choices you make and provide enhanced, more personal features. For instance, we may use such cookies to provide you with responses that are tailored to your location or preference. These cookies can also be used to remember changes you have made to text size, fonts and other parts of web pages that you can customise. The information these cookies collect may be anonymised and they cannot track your browsing activity on other websites.
• Targeting cookies or advertising cookies
  These cookies are used to deliver adverts more relevant to you and your interests. They are also used to limit the number of times you see an advertisement as well as help measure the effectiveness of the advertising campaigns. They are usually placed by advertising networks with the website operator’s permission. They remember that you have visited a website and this information is shared with other organisations such as advertisers. Quite often targeting or advertising cookies will be linked to site functionality provided by the other organisation.
