Privacy policy

What we collect
StumpDeck is a reference site. There is no account, no login and no newsletter database. We collect aggregate page analytics (page path, referrer, country, device class) so we know which calculators are used. We do not sell data and we run no advertising trackers.
Messages sent through the contact form (name, email, message) are delivered by email to the editor and used only to reply; the site does not store them.
Calculator inputs
Every calculator on this site runs entirely in your browser. The diameter, height, access and price figures you type are never sent to a server and are gone when you close the tab.
Analytics and hosting
Pages are served by Vercel, which records standard request logs. Aggregate usage is measured by Google Analytics 4 (property G-152HSZ5MC8) and by Vercel Analytics. Neither builds a cross-site advertising profile of you here; advertising features and ad personalisation signals are not enabled on this property.
Sponsored content
Some articles and vendor listings on this site are paid placements. Payment buys presence, never the page’s verdict or a vendor’s ranking, and every vendor claim is checked against the vendor’s own documentation before it is published. A sponsor never sees anything about you.
