Privacy Policy

Last updated: March 2026

This Privacy Policy explains how PercentagesCalculators.com ("we", "us", "our") collects, uses, and protects information when you visit percentagescalculators.com.

What We Collect

PercentagesCalculators.com does not require you to create an account, provide your email address, or submit any personal information to use any of our calculators. All calculations happen in your browser — no input values are sent to or stored on our servers.

We do collect non-personal usage data automatically through the services below:

  • Google Analytics — collects anonymised data about page visits, session duration, device type, browser, and approximate location (country/region). This helps us understand how people use the site.
  • Google AdSense — displays ads on the site. Google may use cookies to serve ads based on your prior browsing. You can opt out at adssettings.google.com.
  • Netlify — our hosting provider may log standard server access data (IP address, browser type, referring URL, timestamp) for security and operational purposes.

Cookies

We do not set first-party cookies ourselves. Third-party services (Google Analytics, Google AdSense) may set cookies in your browser. You can manage or disable cookies through your browser settings or a browser extension such as uBlock Origin. Disabling cookies will not affect your ability to use any calculator on this site.

How We Use Information

Aggregated, anonymised usage data is used solely to:

  • Monitor site performance and uptime
  • Understand which calculators are most useful
  • Improve existing tools and plan new ones

We do not sell, share, or transfer any data to third parties beyond the services listed above.

Third-Party Services

The privacy policies of our third-party services govern how they handle data collected through their tools:

Your Rights (GDPR & CCPA)

If you are based in the EU or California, you have the right to request access to, correction of, or deletion of any personal data we hold about you. Because we do not collect personal data directly, the most relevant step is to manage cookies through your browser or opt out of Google's ad personalisation.

For any privacy requests or questions, please use our Contact page and we will respond within 30 days.

Children's Privacy

Our site is intended for general audiences. We do not knowingly collect personal information from children under 13. If you believe a child has submitted personal data through our contact form, please contact us and we will remove it promptly.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the site after changes are posted constitutes acceptance of the updated policy.
