Why we use them

When we provide services, we want to make them easy, useful and reliable. Where services are delivered on the internet, this sometimes involves placing small amounts of information on your device, for example, your computer or mobile phone. These include small files known as cookies. They cannot be used to identify you personally.

These pieces of information are used to improve services for you through, for example:

  • recognising that you may already have given a username and password so you don’t need to do it for every web page requested
  • measuring how many people are using services, so they can be made easier to use and there’s enough capacity to ensure they are fast
  • analysing anonymised data to help us understand how people interact with our website so we can make them better

You can manage these small files and learn more about them from the article, Internet Browser cookies- what they are and how to manage them

Log files

Log files allow us to record visitors’ use of the site. The CMS puts together log file information from all our visitors, which we use to make improvements to the layout of the site and to the information in it, based on the way that visitors move around it. Log files do not contain any personal information about you. If you receive the HTML-formatted version of a newsletter, your opening of the newsletter email is notified to us and saved. Your clicks on links in the newsletter are also saved. These and the open statistics are used in aggregate form to give us an indication of the popularity of the content and to help us make decisions about future content and formatting.
