What are ‘cookies’? 

Cookies are small text files which are downloaded to your computer or mobile device when you visit our website or applications. Your web browser (such as Internet Explorer, Mozilla Firefox, Safari or Google Chrome) then sends these cookies back to the website or application on each subsequent visit so that they recognise you and remember things like your personalised details or user preferences. 

Cookies are extremely useful and fulfil several tasks. They help make your experiences with our website as user friendly and pleasant as possible. They remember your preferences and improve your user experience as a whole. 

There are two types of cookies:

  1. Session cookies. These only last for your online session and disappear from your computer or device when you close your browser.
  2. Persistent Cookies. These remain on your computer or device after the browser has been closed and last for the amount of time specified in the cookie. These persistent cookies are activated every time you visit the site on which they were created.

The information generated by the cookie about your use of the website will generally be sent to a Google server in the United States, where it will be saved.

The full IP address will only be sent to a Google server in the USA and truncated there in exceptional circumstances. On behalf of the website provider, Google will use this information to evaluate your use of the website, compile reports on website activity and provide the website provider with other services relating to website activity and internet usage. The IP address transferred from your browser as part of the Google Analytics service will not be combined with other data held by Google. You may prevent the storage of cookies by activating the appropriate browser settings.
