Privacy
policy

The short version

Calculate.to 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.to does not use these to identify or profile anyone.

Fonts. Pages load the IBM Plex typeface family 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

Calculate.to now includes a small number of Amazon affiliate links, on the homepage and a few relevant pages, a short "physical calculator" shelf. If you click one and buy, Calculate.to may earn a small commission at no extra cost to you, as an Amazon Associate. These links are marked as sponsored and set no cookies of our own; Amazon may set its own once you visit their site, under Amazon's privacy notice.

Beyond that: still no analytics, no tracking pixels, no accounts, and no selling of data. If privacy-respecting analytics are ever added, this page will describe exactly what changed before it takes effect. The commitments that will not change: no invasive tracking, no dark patterns.
