Cookies and similar technologies
This site does not set advertising cookies.
- Security. Cloudflare may set a strictly necessary cookie (cf_clearance) to protect the site from automated abuse.
- Visitor analytics and inquiries. Our customer management provider, Singoo (91syun), sets cookies and uses browser storage to keep a visitor identifier (singoo_cookie, singoocookie_cache, singoocookie_etag and singoocookie_png), so that we can count visits and connect an inquiry with the pages viewed. These can last until the end of 2030 unless you delete them.
- Visit statistics. Cloudflare Web Analytics counts visits without using cookies.

You can block or delete cookies in your browser settings, although security checks may then ask you to verify again. Links to WhatsApp and to our social media profiles take you to services with their own policies. If we add marketing cookies, we will update this policy and ask for your consent where required.
