Privacy Policy

Last updated: August 28, 2026

The calculators run entirely in your browser

Every calculator on GravelCalc — the length, width, depth and material fields, and the results they produce — runs as JavaScript in your own browser. The numbers you type in are never sent to our servers, logged, or stored anywhere. There's nothing for us to see, because the calculation never leaves your device.

Accounts and personal information

GravelCalc has no user accounts, no sign-up forms, and no login. We do not knowingly collect names, email addresses, or any other personal information through the calculators or guide pages on this site.

Cookies and tracking

This site does not set its own cookies and does not run any analytics or advertising scripts at this time. If that changes in the future — for example, if we add analytics or ads to keep the site free — this page will be updated to describe exactly what's added and why, before it goes live.

Third-party services

GravelCalc's pages load typefaces (Archivo and Inter) from Google Fonts. Loading a font means your browser makes a direct request to Google's servers, which — like any web request — includes technical information such as your IP address. This is standard behavior for any site using a font CDN. We don't control what Google does with that request; see Google's own privacy policy for details. GravelCalc is hosted on Vercel, which similarly processes standard web request logs (IP address, request time, user agent) as part of serving the site — see Vercel's privacy policy.

Children's privacy

GravelCalc is a general-audience construction and landscaping tool, not directed at children, and we do not knowingly collect information from children.

Changes to this policy

If this policy changes — most likely because we've added a new third-party service — we'll update the "Last updated" date above and describe the change in this document.
