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

  • enabling a service to recognise your device so you don't have to give the same information during one task
  • recognising that you have already given a username and password so you don't need to enter it for every web page requested
  • measuring how many people are using services, so they can be made easier to use and that there is enough capacity to ensure they are fast
  • remembering your audience type selection so we can show you more relevant options and information
