Information we collect

You can use our calculators without creating an account. We do not require you to submit a name, password, or payment details to use the tools.

If you email us, we receive the content of your message and your email address so we can respond.

Like most websites, our hosting provider and analytics tools may process technical data such as IP address, browser type, device type, referring URL, pages visited, and approximate location derived from IP.

Cookies and similar technologies

We may use cookies or local storage for basic site preferences (for example, theme) and for analytics.

If we enable Google Analytics or similar tools, they may set their own cookies according to their policies. You can control cookies through your browser settings.

Advertising

We may display ads through Google AdSense or similar partners. These partners may use cookies or similar technologies to show relevant ads and measure performance, including based on your prior visits to this or other sites.

Google’s use of advertising cookies is described in Google’s Privacy & Terms. You can manage ad personalization in your Google account ad settings and via industry opt-out tools where available.

Until advertising is enabled on this site, no ad cookies are intentionally loaded by us for monetization.

How we use information

We use technical and analytics data to operate the site, understand which tools are useful, fix errors, improve performance, and protect against abuse.

We use email correspondence only to respond to your inquiry and related follow-up.

Sharing of information

We do not sell your personal information.

We may share limited data with service providers that help us run the site (hosting, CDN, analytics, and — when enabled — advertising). They process data under their own terms and only as needed to provide their services.

We may disclose information if required by law or to protect the rights, safety, and integrity of ResiCalc and our users.

Data retention

Server and analytics logs are retained for a limited period needed for security and diagnostics, then deleted or aggregated.

Email correspondence is retained as long as needed to handle your request and for legitimate business records.

International visitors

ResiCalc is operated with infrastructure that may be located in different countries. By using the site, you understand that information may be processed outside your country of residence, where data protection laws may differ.

Children

The site is intended for a general audience interested in electronics engineering. We do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact us and we will delete it.

Your choices and rights

Depending on where you live, you may have rights to access, correct, delete, or restrict certain personal data, or to object to certain processing. Contact us at the email above to make a request.

You can block or delete cookies in your browser; some site features (such as remembering theme) may then work differently.

Changes to this policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top of this page will change when we do. Continued use of the site after an update means you accept the revised policy.
