To make this site work properly, we sometimes place small data files called cookies on your device. Most big websites do this too.
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.
Adjust this part of the page according to your needs. Explain which cookies you usein plain, jargon-free language. In particular:
their purpose and the reason why they are being used, (e.g. to remember users’ actions, to identify the user, for online behavioural advertising)
if they are essential for the website or a given functionality to work or if they aim to enhance the performance of the website
the types of cookies used (e.g. session or permanent, first or third-party)
who controls/accesses the cookie-related information (website or third party)
that the cookie will not be used for any purpose other than the one stated
how consent can be withdrawn.
your display preferences, such as contrast colour settings or font size
if you have already replied to a survey pop-up that asks you if the content was helpful or not (so you won’t be asked again)
