To make this site work properly, we sometimes place small data files called cookies on your device. Most websites do this.

What are cookies?

A cookie is a small text file that a website saves on your computer or mobile device when you visit the site.

It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) over a period of time, so you don't have to keep re-entering them whenever you come back to the site or browse from one page to another.

How we use cookies

A number of our pages use cookies to remember, for one or more of the following reasons:

  • user‑input: such as first‑party cookies to keep track of the user's input when filling online forms, shopping carts, etc.
  • authentication: to identify the user once he/she has logged in.
  • user‑centric security: used to detect authentication abuses.
  • multimedia content player: used to store technical data to play back video or audio content.
  • user‑interface customisation: such as language or font preferences.
  • third‑party social plug‑in content‑sharing: for logged‑in members of a social network.
  • analytics: to anonymously gather statistics.

In some cases the cookies we use are provided by trusted third parties.
