Overview
This Privacy Policy explains what information ElectroMechCalc ("we", "us", "this site") collects when you visit, how that information is used, and the choices available to you. ElectroMechCalc provides free electrical, mechanical, and financial planning calculators, and we aim to collect only the minimum information necessary to operate and improve the site.
Information We Collect
We do not require account creation, and we do not ask visitors to submit personal information to use any calculator. The following limited information may be collected automatically:
- Usage analytics — anonymized data such as pages visited, time on page, browser type, device type, and approximate geographic region (country/city level), used to understand which calculators are useful and where the site can be improved.
- Calculator inputs — values you type into a calculator (e.g. voltage, load, salary, investment amount) are processed locally in your browser to generate a result and are not transmitted to or stored on our servers.
- Email — if you email us directly, we retain that correspondence only for as long as needed to respond to and resolve your inquiry.
Cookies and Similar Technologies
This site uses cookies and similar tracking technologies for the following purposes:
- Essential cookies and local storage — required for basic site functionality, such as remembering your light/dark theme preference. This preference is stored in your browser's local storage on your own device and is not sent to our servers.
- Analytics cookies — used to measure traffic and usage patterns in aggregate, anonymized form.
- Advertising cookies — third-party advertising partners, including Google AdSense, may set cookies on this site to serve and measure the performance of advertisements, and to personalize ads based on your prior browsing activity across websites.
You can control or disable cookies through your browser settings. Disabling cookies may affect some site functionality but will not prevent you from using the calculators themselves.
Third-Party Advertising — Google AdSense
We use Google AdSense to display advertisements on this site. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the internet.
You may opt out of personalized advertising by visiting Google's Ads Settings, or opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.
Third-Party Services
In addition to Google AdSense, this site may use the following categories of third-party services, each of which has its own privacy policy governing the use of your information:
- Web analytics providers (e.g. Google Analytics) for aggregate, anonymized traffic measurement.
- Hosting and content delivery providers (such as Cloudflare, which hosts and serves this site, and Google Fonts), which may process standard server request data (e.g. IP address, browser type) as part of normal web infrastructure operation and security.
Data We Do Not Collect or Share
We do not sell, rent, or trade personal information to third parties. We do not require names, addresses, or financial account details to use any calculator on this site. Inputs to financial calculators (such as EPF, SIP, or CAGR figures) are processed entirely within your browser and are never sent to or stored on our servers.
Children's Privacy
This site is intended for a general audience including students, and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can remove it.
Your Choices
You can manage cookie preferences through your browser settings, opt out of personalized advertising using the links above, and use most of this site's features (including all calculators) without enabling analytics or advertising cookies at all. If you visit from the European Economic Area, the United Kingdom, or Switzerland, you may be asked for consent before personalized advertising cookies are used, and you can change that choice at any time. Depending on where you live (for example, under the GDPR, UK GDPR, or California privacy laws), you may have rights to access, correct, or delete personal information we hold about you, or to object to certain processing; because we do not require accounts and do not store calculator inputs, the only personal information we typically hold is email correspondence you send us. To make a request, contact us at the address below.
Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our practices or for legal and regulatory reasons. The "Last updated" date at the top of this page indicates when the policy was last revised. Continued use of the site after changes constitutes acceptance of the updated policy.
