Privacy Policy
Last updated: June 16, 2026
Our Commitment to Privacy
FitCalCalc ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you visit fitcalcalc.com (the "Site").
Information We Collect
Information You Provide
We do not collect any personal information. All calculator inputs — including your age, gender, height, weight, activity level, and fitness goals — are processed entirely within your web browser using client-side JavaScript. This data never leaves your device and is never transmitted to our servers.
Local Storage
For your convenience, the Site may save your calculator inputs locally in your browser using localStorage. This allows your settings to persist between visits. This data remains on your device and is never shared with or accessible by us. You can clear this data at any time through your browser settings.
Analytics (Google Analytics 4)
We use Google Analytics 4 (GA4) to understand how visitors use our Site. GA4 collects anonymous usage data including:
- Pages visited and time spent on the Site
- Approximate geographic location (country/city level)
- Device type, browser, and operating system
- Referring website or search term
GA4 does not collect personally identifiable information (PII) such as names, email addresses, or precise locations. Google may use cookies for analytics purposes. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
Advertising (Google AdSense)
We may display advertisements through Google AdSense. Google and its advertising partners use cookies to serve ads based on your prior visits to this Site and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this Site and/or other sites on the Internet.
You can learn more about how Google uses data and opt out of personalized advertising by visiting Google's Advertising Policies and Google Ad Settings.
How We Use Information
The anonymous analytics data we collect is used solely to:
- Understand how visitors use the Site and which calculators are most popular
- Improve the Site's content, design, and user experience
- Monitor Site performance and fix technical issues
Cookies
The Site may use first-party cookies for essential functionality (such as remembering your unit system preference) and third-party cookies for analytics and advertising. You can control cookie settings through your browser. Note that disabling cookies may affect certain features of the Site.
Third-Party Services
We use the following third-party services that may collect anonymous data:
- Google Analytics 4 — website analytics
- Google AdSense — advertising (when enabled)
- Google Fonts — web font delivery
- jsDelivr CDN — delivery of Chart.js library
Children's Privacy
The Site is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe we have inadvertently collected such information, please contact us and we will promptly remove it.
Data Security
Since all calculator processing occurs locally in your browser and no personal data is stored on our servers, the risk of a data breach affecting your personal information is minimal. However, no method of transmission over the Internet is 100% secure.
Your Rights
Depending on your jurisdiction, you may have rights regarding your personal data, including the right to access, correct, or delete your data. Because we do not collect personal data, these rights are inherently protected — there is nothing for us to delete or correct. For any questions, contact us at the email below.
Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. We encourage you to review this policy periodically.
