Privacy Policy

1. Overview & Client-Side Data Handling

At CircuitCalc (circuitcalc.dev), we prioritize user privacy. All calculators and computational tools hosted on this platform operate strictly client-side within your web browser. Any numeric values, voltages, currents, or resistor parameters you enter are processed in memory on your local device and are never uploaded, logged, or saved to our servers.

2. Google AdSense & Advertising Cookies

This website is monetized via Google AdSense and third-party advertising partners to provide free access to all calculators.

• Third-party vendors, including Google, use cookies to serve advertisements based on a user's prior visits to this website or other websites on the Internet.
• Google's use of advertising cookies enables it and its partners to serve targeted ads to our users based on their visits to CircuitCalc and/or other sites across the World Wide Web.
• Users may opt out of personalized advertising by visiting Google Ads Settings or by visiting aboutads.info.

3. Local Storage

We may use your browser's localStorage to remember your recently used calculators so that you can switch tools easily from the top search bar. This information remains strictly on your local device and is never transmitted to us or any third party.

4. Analytics

We may utilize privacy-friendly, cookieless analytics tools (such as Vercel Analytics or Plausible) to track aggregated, non-personally identifiable metrics like pageviews, referral sources, and device types to help us optimize calculator performance and Core Web Vitals. No personal profiling or cross-site tracking takes place.
