Common questions
Is it really free?
Yes. The embed is free for any site -- personal blogs, RV forums, commercial sites, manufacturers, trade schools. You only need to keep the small backlink visible.
Does the embed track my visitors?
The calculator uses the same privacy-friendly analytics as voltplan.app (Umami, no cookies, no personal data). Clicks on the “Buy on Amazon” links go through our affiliate router.
Can I change the theme or language after embedding?
Yes -- just edit the theme and lang query parameters in the iframe URL.
