Privacy
policy

The short version

Calculate does not collect, store, or share personal data. There are no cookies, no tracking pixels, no analytics scripts, no accounts, and no forms. Every calculation runs entirely in your browser using JavaScript — the numbers you type never leave your device and are never seen by us.

What the site technically touches

Hosting. The site is served as static files. Like any web server, the host may keep standard access logs (IP address, requested page, browser type) for security and operations; Calculate does not use these to identify or profile anyone.

Fonts. Pages load the Space Grotesk typeface from Google Fonts, which means your browser requests font files from Google's servers — subject to Google's privacy policy. No other third-party resources are loaded.

If this ever changes

If privacy-respecting, cookieless analytics or clearly disclosed affiliate links are added in the future, this page will describe exactly what changed before it takes effect. The commitment that will not change: no invasive tracking, no selling of data, no dark patterns.
