Global cookie notice

We use the word ‘cookie’ to refer to online cookies and similar technologies that store or access information on your device.

Definition of cookies

Cookies and similar technologies are small tools used online to remember things about you and your device when you visit our site. For instance, they remember your language preferences, keep you logged in, or analyse your browsing activity to show you ads you may be interested in.
Cookies can be native – meaning that they are owned by the operators of the website you are visiting – or owned by a third-party who can place cookies from their own separate domain.
Third-party cookies may be subject to distinct privacy and cookie policies, which the owners are responsible for making accessible to you.

You can also delete the cookies stored on your computer using your internet browser settings.
Disabling cookies does not prevent you from browsing our site, although the use of some functionalities may be limited.
