What are cookies?

Cookies are small text files that are transferred to your computer or mobile device when you visit a website or app. They’re created when you visit a website or other service that uses cookies.

Cookies are typically used to:

  • Remember information about you, so you don’t have to provide it every time you visit a site.
  • Help us understand how people are using our site so we can make it better.
  • Help us personalise the site by remembering your preferences, showing you content that may be most relevant to you and remembering your progress, so you can pick up where you left off if you’re completing a form or watching a video, for example.
  • Find out if our emails have been read and if you find them useful.
