About

Privacy Policy

The short version: we don't collect anything, because there's nothing to collect.

The Short Version

Every tool on HexCalculator runs entirely as client-side JavaScript in your browser. Whatever you type into a conversion tool is processed locally and is never transmitted to any server, logged, or stored.

Information We Collect

As of this writing, this site runs no analytics, no advertising, and no tracking scripts of any kind — your visit isn't measured by us at all. Your web server or CDN (Cloudflare) may keep standard infrastructure-level access logs (IP address, requested URL, timestamp) for security and reliability purposes; we don't have a separate analytics layer on top of that.

If that ever changes — for example, if analytics or advertising is added later — this policy will be updated first, and the "Last updated" date below will reflect it.

Cookies

This site does not set any first-party cookies.

How the Tools Work

Conversions use standard browser JavaScript APIs (including TextEncoder/TextDecoder for UTF-8, and BigInt for large-number math) running entirely within your browser's sandbox. No conversion input or output ever leaves your device.

Children's Privacy

This site does not knowingly collect information from anyone, including children under 13, because it does not collect personal information from any visitor.

Changes to This Policy

Any future change to how this site handles data will be reflected here, with an updated date below.
