Privacy Policy

Last updated: December 2025

                We collect ZERO personal data.

                No cookies • No tracking • No analytics • No ads • No accounts

Your Privacy is Our Priority

At ResistanceCalculator.online, we believe that great tools should respect your privacy completely. That’s why we made a promise from day one: we will never collect, store, or share any personal information about you.

What We Do NOT Collect

No name, email, or personal identifiers
No IP address logging
No cookies (not even functional ones)
No usage analytics or tracking pixels
No advertising partners
No third-party scripts
No data is ever sent to any server except when you voluntarily use the contact form

What Happens When You Use the Calculator

All calculations happen 100% in your browser. Nothing is sent to our server. Your resistor values, voltage inputs, color codes, everything stays on your device and is gone the moment you close the tab.

Contact Form (Only Time We Receive Data)

The only time we receive any information is when you choose to send us a message via the Contact page. In that case:

We receive only what you type: name, email, and message
We use this solely to reply to you
We do not store it long-term or share it with anyone
Messages are processed via a privacy-first service (Formspree or similar)

Third-Party Services

We do not use Google Analytics, Meta Pixel, Cloudflare insights, or any advertising/tracking services. The only external request is the contact form submission (if used), which goes directly to our secure, privacy-respecting form handler.

Children’s Privacy

Our tool is safe and appropriate for users of all ages, including children under 13. Since we collect no personal information, we fully comply with COPPA and GDPR-K requirements.

Changes to This Policy

If we ever change our privacy practices (which would only happen if we add a feature that requires data), we will update this page clearly and immediately. But our core promise remains: your privacy comes first, always.
