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
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.
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. You can reopen the same controls at any time.
