Cookie Preferences
This website currently uses limited browser storage required to provide certain site functionality. It does not currently use advertising or marketing cookies.
Browser storage used
Two forms of browser storage are technically distinct from cookies. localStorage persists until it is deleted; sessionStorage is cleared automatically when the browser tab is closed. This website uses sessionStorage only, and does not use localStorage.

Language preference
The language selector does not store a preference. The selected language is expressed only in the address of the page you are viewing: English pages are served from the site root, French pages from the /fr path and German pages from the /de path.
No cookie, no localStorage entry and no sessionStorage entry is created when you change language, and your browser language is not used to redirect you automatically.
Analytics, advertising and tracking
This website does not use website analytics, advertising, retargeting, social-media tracking or session-recording technologies. No analytics, tag-management, advertising or profiling scripts are installed.
Third-party content
Typefaces used on this website are self-hosted and served from this website's own domain. No external font service, content-delivery network or other third-party host is contacted automatically when a page loads.
There are no embedded video players, maps, social feeds, chat tools or third-party form widgets on this website. Links to external sites, including news articles and videos, are ordinary outbound links: no third-party content is loaded until you choose to follow them.
Managing browser storage
You can clear the storage described above at any time using your browser's privacy or site-data settings. Because both entries are session-based, closing the browser tab also removes them. Clearing the website-notice entry means the notice will be shown again on your next visit.
