Privacy and Data Handling

Cookies and traffic analysis

This site uses Google Analytics 4 (GA4) to understand how the site is used. GA4 writes cookies named _ga and _ga_* to your browser to distinguish unique visitors and sessions. These are non-essential, analytics cookies.

This site carries no advertising tags, no retargeting pixels and no cross-site advertising trackers, and we do not use this data to serve advertising. When you submit the inquiry form, we tell GA4 that an inquiry took place, together with where the form was, the channel you arrived through, the site language and the product code you asked about, so that we can see which channels bring enquiries. Your name, email, phone number and message are never sent to Google, and we do not store GA4’s visitor identifier with your inquiry.

If you prefer not to be counted, you can block this site’s cookies in your browser settings, or install Google’s official Google Analytics Opt-out Browser Add-on (tools.google.com/dlpage/gaoptout). Everything on this site continues to work if you do.

What personal data we collect

We receive personal data only when you choose to submit the inquiry form. Its fields are: name, company, email, phone, country or region, the product code you are asking about, and your message.

Only name, email and message are required. You may leave the rest blank.

When you submit the form, we also record how you reached the site: the domain of the referring website (for example a search engine or an AI assistant), the first page you landed on, any campaign (UTM) tags on the link, and whether you arrived through an ad click (only whether one was present, never the click identifier). Until you submit, this is held only in your browser tab’s sessionStorage — not a cookie, not shared across websites, and cleared when you close the tab. We never record the words you typed into a search engine.

What we use it for

Solely to answer your inquiry, quote, and continue the resulting business conversation. We do not use your data for marketing unrelated to your inquiry, and we do not sell or rent it to third parties.

If your inquiry concerns a specific part number, that number is recorded with it so we can prepare the correct specification and price.

Where it is stored

Inquiries are written to our content management system (Sanity) as a sales record, and a notification email is sent to our sales staff. The site itself is hosted on Vercel.

These providers are necessary to process your inquiry and each operates under its own data processing terms; traffic analysis is provided by Google. Beyond them, we do not pass your data to other third parties.

How long we keep it

Inquiry records are kept for a reasonable period after the business relationship ends, so that follow-up orders, warranty and complaints can be handled. You may ask us to delete them at any time.

Your rights

You may ask to see, correct or delete the personal data we hold about you, and you may ask us to stop using it to contact you.

Please contact us by email and we will act within a reasonable period. To protect your data we may first need to verify your identity.

Outbound links

Articles on this site cite external standards bodies and organisations as sources. Following those links takes you off this site, and the privacy policy of the destination is theirs, not ours.
