How ElectroCalc collects, uses, and protects information when you use our calculators.
ElectroCalc ("we," "our," or "us") provides free electrical engineering calculators at electrocalc.in. This page explains what information is collected when you visit, and how it's used. We built these tools to be genuinely useful and free — this policy exists so you know exactly what happens behind the scenes.
ElectroCalc's calculators run entirely in your browser. Values you type into a calculator (like resistance, voltage, or battery capacity) are processed locally on your device and are never sent to our servers or stored by us.
We do use third-party services that may collect limited technical information automatically, described below.
We use Google Analytics to understand how visitors use the site — which calculators are popular, how long people stay, and general traffic patterns. This is anonymized, aggregate data and does not identify you personally. Google Analytics may use cookies to distinguish unique visitors across sessions.
You can learn more about how Google collects and processes this data at Google's Privacy & Terms page.
ElectroCalc uses Google AdSense to display advertising. Google and its partners may use cookies to serve ads based on your prior visits to this or other websites. This helps keep our calculators free to use.
Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings.
If you are located in the European Economic Area, the UK, or Switzerland, you will be shown a consent banner allowing you to choose whether to allow personalized advertising, reject it, or manage your preferences in detail.
Cookies are small text files stored on your device. ElectroCalc itself does not set functional cookies for the calculators to work — any cookies present come from the third-party services described above (Analytics and AdSense). You can disable cookies through your browser settings at any time, though this may affect ad personalization and analytics accuracy.
Our site includes a Discussion/comments section powered by Giscus, which uses GitHub for authentication and comment storage. If you choose to comment, that interaction is governed by GitHub's Privacy Statement, not this policy.
ElectroCalc is a general-audience technical reference tool and is not directed at children under 13. We do not knowingly collect personal information from children.
We may update this policy occasionally to reflect changes in our practices or for legal reasons. The "Last updated" date at the top of this page will reflect the most recent revision.
Questions about this policy or how your information is handled? Reach out via the About page or through the Discussion section on any calculator page.
