A cookie is a small file of letters and numbers that we may store on your browser or the hard drive of your computer or device. They cannot be used to identify you personally.
Cookies 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 several times during one task;
- recognising that you may already have given a username and password so you don’t need to do it for every web page requested; and
- 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
