Privacy policy
Last updated October 8, 2026
This policy explains what happens to your information when you use CalcBelt (calcbelt.com).
What you type stays on your device
Every calculation runs in your web browser. Measurements and prices you enter are not sent to our servers or anyone else. Your unit choice (US or metric) is remembered in your browser's local storage so the next calculator opens the same way; you can clear it by clearing your browser's site data.
Hosting and logs
The site is served by Cloudflare. Like any web host, Cloudflare processes technical data such as your IP address to deliver pages and protect the site from abuse. See Cloudflare's privacy policy.
Cookies and advertising
We don't set tracking cookies today. If we add advertising or analytics in the future, we will update this page first and, where the law requires it, ask for your consent.
