In short
This website does not use advertising or tracking cookies and loads no third-party trackers or fonts. Nothing is shared with advertisers.
Videos. Some pages show test videos hosted on YouTube. Only a thumbnail stored on our own server is shown until you press play; then the player loads from YouTube in privacy-enhanced mode (youtube-nocookie.com), and Google may store data in your browser under its own privacy policy.

Technical cookie for Silentflex staff
Only on the browsers of Silentflex staff who activate it with an internal link is the sf_staff cookie stored (strictly necessary, 12 months), which exempts that browser from the query limits of the tools. It is never set for visitors.
Analytics and marketing
None are active today. If we ever add them, they will stay off until you accept them in cookie settings, and a signal such as Global Privacy Control will keep marketing off automatically.
