Privacy Policy

Effective / last updated: 2026-06-25

1. What we collect and what we do not

FitCalc has no sign-up process and does not request or collect personally identifying information such as your name or contact details. Values you enter into the calculators (weight, load, reps, skeletal muscle mass, body fat percentage, etc.) are used only within your browser, disappear automatically, and are never transmitted to or stored on our servers.

However, the following information may be generated and collected automatically as you use the site:

• Access IP address, browser type and version, operating system, and visit time
• Pages visited, referring page (referrer), and device information
• Anonymous identifiers via cookies and similar technologies

2. Use of cookies

FitCalc may use cookies to provide the service and serve ads. A cookie is a small text file a website stores in your browser to remember visits and settings.

You can refuse or delete cookies in your web browser settings. Note that blocking cookies may limit some features and ad personalization. Cookie settings can be changed in each browser's settings menu (Chrome, Safari, Edge, etc.).

3. Google AdSense and third-party advertising

FitCalc serves ads through Google AdSense. Third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this and other sites.

• Google uses advertising cookies (e.g. the DoubleClick cookie) to serve ads based on your visits to this site and others.
• You can opt out of personalized advertising at Google Ads Settings.
• You can review and opt out of third-party vendor cookie use at www.aboutads.info.
• Learn how Google handles data at How Google uses data from sites that use its services.

4. Analytics tools

To improve the service, we may use web analytics tools such as Google Analytics. These tools use cookies to collect anonymized statistics such as pages viewed and time on site, and do not identify any specific individual.

5. Data retention and third-party sharing

Because FitCalc does not directly collect or store your personal information, no separate retention period applies. Automatically collected access and cookie information is processed and retained per the policies of the relevant providers such as Google. Except as required by law, we do not sell or arbitrarily share user information with third parties.

6. Your rights

You have the right to refuse data collection through your browser cookie settings and can disable personalized ads in Google Ads Settings. For questions about data handling, contact us at the address below.

7. Children's privacy

FitCalc is not primarily directed at children under 14 and does not knowingly collect children's personal information.

8. Changes to this policy

This privacy policy may be revised due to changes in law or the service, and any changes will be announced on this page. For material changes, we update the effective date.
