What is a cookie?
A cookie is a small file stored or read on your device when you visit a website. Some trackers are essential to the website’s operation; others require your consent.
Categories used
- Necessary cookies: operation, security and storage of your consent choices. These cannot be disabled through the consent manager.
- Audience measurement: statistics on visits and use of the website. These trackers are only placed after you agree, where consent is required.
- Third-party content or services: some embedded content may place trackers, only after you agree where consent is required.
Your choice
On your first visit, you can accept, refuse or customise non-essential cookies. Refusing is as easy as accepting. You can change your choice at any time using the “Manage my cookies” link in the footer.
Duration
Your choice is stored for a limited period, after which you may be asked for consent again. Trackers remain active only for as long as necessary for their purpose and within the applicable maximum periods.
