Calculator Data

Every calculator on EE Design Calc runs entirely in your browser using JavaScript. Values you type into a calculator (voltages, currents, MCU clocks, etc.) are never sent to a server, never stored, and never logged. Closing or reloading the page clears everything.

Advertising and Cookies

This site uses Google AdSense to display ads. Google and its partners use cookies and similar technologies to serve ads based on your prior visits to this or other websites. This may include personalized advertising unless you have opted out.

You can review or opt out of personalized advertising by visiting Google Ads Settings or aboutads.info. For details on how Google uses data from sites that use its services, see How Google uses information from sites or apps that use our services.

This site is hosted on Vercel. Vercel's infrastructure may log standard technical data (IP address, request time, user agent) for security and performance purposes, independent of anything EE Design Calc itself does. See Vercel's Privacy Policy for details.

Children's Privacy

This site is intended for engineers and students and is not directed at children under 13. No personal information is knowingly collected from anyone.
