This public website does not use advertising or third-party tracking tools. Language is selected through the page address. The search function filters page links locally in your browser. Video playback uses the limited first-party cookie described below.
For video-play deduplication, we use a random first-party cookie valid for 30 minutes and a short-lived server-side digest. These are used only to avoid repeated counting, not to identify you. We do not record IP addresses or browser fingerprints for this purpose. Repeated playback of the same video in the same browser counts once within 30 minutes.
