Privacy Policy

Last updated: October 12, 2026

Your privacy matters to us. Here's everything you need to know about how we handle your data.

Short Version

We don't sell your personal data, and the numbers you type into our calculators never leave your browser. Where they are enabled, we use Google Analytics for anonymous usage stats and Google AdSense for ads. That is it.

Information We Collect

CalcPool is designed with privacy as a core principle. The data you enter into our calculators is processed entirely in your browser and is never transmitted to our servers.

We collect the following minimal information automatically:

  • Usage data: Pages visited, time on site, and general location (country/city level) via Google Analytics. This is anonymous and aggregated.
  • Advertising data: Where ads are enabled, Google AdSense may use cookies to serve relevant ads. See Section 4 for details.
  • Contact messages: Our contact form opens your own email app to message us, so we receive your name, email address, and whatever you write — and use it only to reply. We do not store it in a database.

How We Use Information

  • To understand how our tools are used and improve them
  • To respond to contact form submissions
  • To show non-intrusive advertisements, where enabled, that help keep our tools free

We do not sell, trade, or transfer your information to third parties for marketing purposes.

Calculator Inputs

All data you enter into CalcPool calculators (wake times, financial figures, personal health data, etc.) is processed entirely client-side in your browser using JavaScript. This data is never sent to our servers and is not stored anywhere by CalcPool.

Privacy First

All calculations happen locally in your browser. Your sensitive data never leaves your device.

Google AdSense and Cookies

Where advertising is enabled, we use Google AdSense to display advertisements. Google may then use cookies to serve ads based on your prior visits to our website or other websites. You can opt out of personalised advertising by visiting Google Ads Settings.

For more information on how Google uses data, visit the Google Privacy Policy.

Google Analytics

We use Google Analytics to understand how visitors use our site. Google Analytics collects anonymous information including browser type, pages visited, time spent on pages, and general geographic location. This information is not personally identifiable.

You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.

Cookies

CalcPool itself does not set any first-party cookies. Third-party services (Google AdSense, Google Analytics) may set cookies in accordance with their own privacy policies.

You can control cookies through your browser settings. Disabling cookies may affect the functionality of third-party services but will not affect our free tools.

Children's Privacy

CalcPool does not knowingly collect personal information from children under the age of 13. Our tools are designed for general audiences. If you believe a child has submitted personal information to us, please contact us and we will delete it promptly.

Third-Party Links

Our website may contain links to external websites. We are not responsible for the privacy practices of those websites and encourage you to read their privacy policies.

Your Rights

Depending on your location, you may have the following rights:

  • The right to access personal data we hold about you
  • The right to request deletion of your data
  • The right to opt out of marketing communications
  • Rights under GDPR (EU residents) or CCPA (California residents)

To exercise any of these rights, contact us at hello@calcpool.com.

Changes to This Policy

We may update this privacy policy from time to time. We will notify you of significant changes by updating the "Last updated" date at the top of this page. Continued use of CalcPool after changes constitutes acceptance of the updated policy.
