NetCalc is a static client-side calculator suite. The HTML and JavaScript are served from Cloudflare Pages and run entirely in your browser. We do not require accounts, we do not ask for personal information, and we do not transmit your calculator inputs to any server we control.
Browser local storage is used by some tools (the practice quizzes and Network Planner) to keep your in-progress state across page reloads. That data stays in your browser and is not visible to us.
Cloudflare Pages serves this site. Cloudflare receives standard request logs (IP address, user agent, referrer, request path) for the purpose of delivering pages and protecting against abuse. See Cloudflare's privacy policy.
Google Fonts serves the Inter typeface. Google receives standard font-request metadata. See Google Fonts FAQ.
If advertising is enabled in the future, this section will be updated to describe the ad network's data practices.
NetCalc itself sets no cookies. Cloudflare may set technical cookies for security and rate limiting (typically named __cf_bm or similar). These have a short lifetime and are not used for tracking across sites.
NetCalc is intended for engineering and educational use. We do not knowingly collect any information from children under 13.
Because we do not collect personal data, there is nothing to access, correct, export, or delete on our side. You can clear NetCalc's local-storage state at any time via your browser's developer tools (Application → Local Storage → netcalcs.pages.dev).
