The contact form
When you press “Send enquiry”, the fields you entered are posted to the site host. The site is hosted by Netlify as static files; enquiry submissions are stored by Netlify Forms (Netlify, Inc.) and forwarded by email to W.Y. Group sales. Netlify may also keep ordinary server logs. A confirmation appears only after Netlify accepts the submission. If it does not, nothing is shown as sent and the page offers an email draft to mrkt@wyholding.eu instead.
“Open an email draft instead” builds a mailto link and asks your device to open it. That draft stays in your email program and goes out only when you press send; the website cannot confirm delivery.
What stays in your browser
The calculator keeps rows in local storage on your device so the English and Chinese calculators can share them. That storage is not an account. You can clear it with the reset button or your browser settings. The language switch is a normal link; it does not set a tracking cookie.
Who is who
Sales enquiries are addressed to W.Y. Group at the sales email above. Manufacturer pages describe SLSB International. Sending technical documents is still your choice of recipient. This notice does not merge the two organisations into one controller, because the papers use more than one legal name and this site does not pick a corrected one.
Other sites
Links to the European Commission, EEX, Ship & Bunker, the manufacturer website and the manufacturer’s social pages leave this site. Their privacy terms are theirs. Fonts may be requested from Google Fonts when a page loads. This site does not add an analytics product. The old shared-folder link is not published.
