Cookies
When we provide services, we want to make them easy, useful and reliable. Where services are delivered over the internet, this sometimes involves placing small amounts of information on your device, for example your computer or mobile phone. These pieces of information include small files known as cookies. We do not use them to identify you personally.
The small pieces of information we store on your device are used to improve services we deliver to you by:
- enabling a service to recognise your device so you don't have to give the same information to us 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 you request from us
- measuring how many people are using services, so they can be made easier to use and so that we provide enough capacity to ensure they are fast
How to manage cookies
You can manage these small files yourself and learn more about them by visiting the following link "Internet browser cookies - what they are and how to manage them". Please be aware that if you choose to refuse cookies, some website functionality may not work for you.
Types of cookies
There are two broad categories of cookies: 'first party cookies' and 'third party cookies'.
First party cookies are sent directly by us to your device, and are used only by us to recognise your computer when it revisits that website.
Third party cookies are sent by an external third party that either provides functionality to or services through our website, for example video clips. They enable that third party to recognise your computer when it visits our website and also when it visits some other websites.
Cookies can remain on your device for different periods of time. Some cookies are 'session cookies', meaning that they exist only while your website browser is open. These are deleted automatically once you close your browser.
Other cookies are 'permanent cookies', meaning that they survive after your browser is closed. They can be used by websites to recognise your computer when you later re-open your browser and browse the internet again.
We only send 'session cookies' through our website, although third parties providing functionality to or services through our website may send 'permanent cookies' to your device.
