Data controller

Maarten de Klerk (sole proprietorship), Chamber of Commerce (KVK) no. 42048341, Vossenstraat 19, 6286BW Wittem, Netherlands.

Contact form

The contact form on the contact page asks for your name, email address, subject and message. This data is never sent to a server and never stored by me. When you submit it, your browser builds a mailto: link with that information pre-filled and opens your own email app — only once you actually hit send there does the message reach me, as a regular email.

Cookies, tracking and analytics

This site uses no cookies, no tracking, and no analytics or advertising services (such as Google Analytics). Nothing about your visit is measured or tracked.

The site does use two small, functional storage mechanisms in your browser (not cookies, but similar local storage):

• Theme preference — whether you're viewing the site in dark or light mode, remembered so you don't have to choose again every time.
• Session flag — whether you've already seen the intro animation during this visit, so it doesn't replay on every page.

Both stay purely local in your own browser, are never sent to me or anyone else, and don't identify you.

Hosting

This site is hosted on GitHub Pages. As with any website, the hosting provider keeps standard server logs (such as IP address and time of visit) for security and technical operation of their infrastructure — this happens outside my control, and I have no access to or control over it.
