What the calculator stores
Nothing leaves your device. The stack you build lives in your browser while the page is open. Your light or dark mode choice is saved in your browser's local storage so the site remembers it.
Analytics and ads
We use privacy-friendly, cookie-free analytics to count page views. When ads run, they are served by Google AdSense, which may use cookies to show relevant ads. You can manage ad personalization at Google's Ad Settings page. Visitors in regions that require it are asked for consent first.
If you email us, we use your message only to reply. We do not sell or share it.
