What is a cookie?
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.
You can change your choice at any time with Cookie settings in the footer.
We use cookies to distinguish you from other users of this service. This helps us to provide you with a good experience when you browse the service and also allows us to improve our service to you.
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

We anonymise the last 3 digits of all user IP addresses for Google Analytics, so that we can ensure that you are protected (you can read more about how this works here). We can only see a general overview of which regions and cities you may come from, not where individuals access from.
