Privacy Policy

Last updated: January 1, 2025

ProCalcTools ("we," "us," or "our") operates procalctools.com. This Privacy Policy explains how we collect, use, and protect information when you use our website.

Information We Collect

Information You Provide

Our calculators run entirely in your browser. We do not collect, store, or transmit the numbers you enter into any calculator on this site. All calculations happen locally on your device.

Automatically Collected Information

We use Google Analytics to understand how visitors use our site. This may collect:

  • Pages visited and time spent
  • Browser type and operating system
  • Approximate geographic location (country/region level)
  • Referring website

This data is aggregated and anonymized — it does not identify you personally.

Advertising

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

Cookies

We use cookies for:

  • Analytics: Google Analytics cookies to understand site usage
  • Advertising: Google AdSense cookies for relevant ad delivery
  • Preferences: Optional cookies to remember your unit preferences (metric/imperial) across sessions

You can disable cookies in your browser settings. Some features may not function properly without cookies.

Third-Party Services

Our site uses these third-party services, each with their own privacy policies:

Children's Privacy

Our site 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 personal information to us, please contact us.

Data Retention

Since we do not collect personal data directly, there is no user data for us to retain or delete. Google Analytics data is retained per Google's standard policies (26 months by default).

Your Rights

Depending on your location, you may have rights under CCPA (California) or other applicable laws. Since we do not sell personal data and do not directly store user-identifying information, most data requests would be directed to our third-party providers (Google).

Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top reflects the most recent revision. Continued use of the site after changes constitutes acceptance.
