  • No accounts, no forms that collect personal data. The calculator runs entirely in your browser; your inputs aren't sent anywhere.
  • No tracking cookies, no third-party scripts or fonts. We store one setting in your browser's local storage: your light/dark theme choice.
  • Analytics: none at present. If we add analytics, it will be a privacy-friendly, cookieless tool that only measures aggregate page views, and this page will be updated first.
  • Server logs: our hosting provider may keep standard access logs (IP address, user agent) for security and operations.
  • Affiliate links: when you click one, the vendor's site may set its own cookies under its own privacy policy.
