Privacy Policy

Effective date: 15 January 2026

Summary

M-Convert does not collect personal information. All conversions run entirely in your browser. No conversion input is transmitted to any server. No cookies are set. No third-party analytics or advertising services are used.

What Data We Do Not Collect

M-Convert does not collect, store, or transmit:

  • Your name, email address, or any identifying information.
  • The values you enter into the converters.
  • Your IP address (beyond the ordinary technical handling performed by Cloudflare as a content-delivery network).
  • Browser fingerprints or device identifiers.
  • Any data from cookies or similar storage except as described below.

Local Storage

M-Convert may use your browser's localStorage to remember:

  • Your theme preference (light or dark).
  • Recently used converters.
  • Converters you have marked as favorites.

This data stays on your device. It is never sent to any server. You can clear it at any time by clearing your browser's site data for M-Convert, or from the "Recent" page within the site.

Cookies

M-Convert does not set cookies. If Cloudflare's content-delivery network sets a cookie for security or DDoS-mitigation purposes, it will be a functional cookie that does not identify you and is not used for advertising or analytics.

Third-Party Services

M-Convert does not load any third-party analytics, advertising, social-media, or tracking services. The only external service involved in serving the site is Cloudflare Pages, which delivers the static assets. Cloudflare's privacy policy applies to the network layer.

Links to External Sites

M-Convert may link to external resources such as the BIPM, NIST, or IEEE for reference. When you click such links, you leave M-Convert and are subject to the destination site's privacy policy. M-Convert is not responsible for the privacy practices of external sites.

Children's Privacy

M-Convert is not directed at children under 13 and does not knowingly collect any personal information from anyone, including children.

Changes to This Policy

If this policy changes materially, the effective date at the top of this page will be updated. Because M-Convert does not collect user contact information, changes cannot be communicated directly — please check this page periodically.
