Privacy Policy

1. Overview

At ResistCalc, we believe engineering utilities should prioritize user privacy. We do not require accounts, sign-ups, or personal identity verification to use our calculation tools.

2. Local Storage and Client Execution

All mathematical calculations (color code decoding, inverse queries, series/parallel sums) execute 100% locally inside your web browser. Resistance values entered are never recorded on external servers. We store user preferences (such as light/dark mode selection) solely in your browser's local storage.

3. Contact Submissions

If you voluntarily choose to contact us via the contact form, your name, email address, and message content will be used exclusively to reply to your inquiry. We do not sell or monetize personal contact data.

4. Analytics and Cookies

We may collect non-identifiable, aggregated technical telemetry (e.g., browser type, page views, regional language headers) solely to diagnose performance and maintain optimal uptime.
