Privacy Policy

Effective Date: January 31, 2026

MechanicsCalc ("we," "our," "the site") operates the website at mechanicscalculator.com. This policy explains what data is collected, how it is used, and your rights.

What We Collect

All calculators run entirely in your browser. We do not collect, store, or transmit any of the values you enter into the calculators. No account or signup is required to use the site.

We may collect the following through third-party services:

Usage analytics: Pages visited, time on site, referral source, device type, and browser. This data is aggregated and anonymous.
Cookies: Used by advertising and analytics services (see below).

Advertising

We use Google AdSense to display advertisements. Google may use cookies and similar technologies to serve ads based on your prior visits to this site and other websites. You can opt out of personalized advertising by visiting Google's Ads Settings.

Third-party vendors, including Google, use cookies to serve ads based on your visits to this and other websites. You may opt out of the use of cookies for personalized advertising by visiting www.aboutads.info.

Cookies

This site uses cookies for the following purposes:

Essential: Storing your dark/light mode preference (localStorage, not a cookie, but mentioned for transparency).
Advertising: Google AdSense uses cookies to serve relevant ads and measure ad performance.
Analytics: Understanding how visitors use the site so we can improve it.

You can control cookies through your browser settings. Blocking cookies may affect ad display but will not affect calculator functionality.

Your Rights (GDPR / EEA Visitors)

If you are located in the European Economic Area, you have the right to:

Access the personal data we hold about you
Request correction or deletion of your data
Object to or restrict processing of your data
Withdraw consent for non-essential cookies at any time

Since we do not collect personal data directly (calculators are client-side only), these rights primarily apply to data collected by third-party advertising and analytics services. You can manage this through the cookie consent banner or your browser settings.

Your Rights (CCPA / California Visitors)

California residents have the right to know what personal information is collected and to request its deletion. We do not sell personal information. Any data collected is through third-party advertising services as described above.

Children's Privacy

This site is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
