Privacy controls
Cookie Notice
The international website uses essential storage for your privacy choice, optional first-party analytics only after permission, and cookieless page counts without permission.

Essential preference storage
th_analytics_consent records whether you accepted or rejected optional analytics. It is a first-party preference cookie retained for up to 180 days. It is necessary to remember and enforce your choice and is not used to identify you.
Optional first-party analytics
Session analytics is disabled before permission. If you accept, the current browser tab receives a random session identifier in sessionStorage. It expires when the tab closes and is regenerated after 30 minutes of inactivity.
Analytics can record page paths and types, approximate reading time and depth, predefined button interactions, report-download intent, inquiry-form progress, device class and limited campaign labels. It does not record form content, original IP addresses, full referrer URLs, search terms, advertising identifiers or a complete browser fingerprint.
Detailed events are retained for 90 days. Aggregated statistics are retained for approximately 24 months. We do not use third-party advertising trackers, combine this information across unrelated websites or sell analytics data.
Cookieless page counts
Before permission, after you reject analytics, or when Do Not Track or Global Privacy Control is enabled, we only count page views. Each view sends one request with the page path, the referrer category and domain, limited campaign labels (utm_source, utm_medium, utm_campaign, utm_content) and a coarse device class (desktop, tablet or mobile) derived from the browser’s user agent. Nothing is written to cookies or browser storage and no identifier is created. The IP address and user-agent string are not stored: the server only adds the view to an hourly total, which cannot be linked to you or to your other visits. The IP address is used only briefly in memory to limit abusive traffic. These totals are retained for approximately 24 months.
Necessary service cookies
Restricted administration routes use secure authentication and OAuth state cookies. These are limited to authorized operators, are necessary for account security and do not enable public visitor analytics.
Change your choice
Rejecting optional analytics does not limit public content, report downloads or inquiry forms. Do Not Track and Global Privacy Control are also respected: they turn off session analytics, leaving only the cookieless page counts described above. You can reopen the same controls at any time.
