Privacy Policy

1. 100% Browser-Local Processing

All calculations performed on Health Fitness Calculator (including BMR, TDEE, Body Fat %, Calorie targets, and Macronutrients) run locally using client-side JavaScript.

Your physical measurements (height, weight, age, biological sex, body circumference) are processed in real-time in your device's memory and are never transmitted to our web servers or any external databases. When you close or refresh the tab, that transient session data is cleared.

2. No Account Creation or Sign-Up

We do not require you to create an account, log in, or provide personal identifying information to use any calculator on this website. All tools remain completely open and accessible without user profiles.

3. Cookies & Local Browser Storage

Our application may use your browser's localStorage to remember your selected preferences (such as Metric vs Imperial units) for a smoother user experience across page visits. This data remains strictly stored on your own device and is never sent to our servers.

4. Website Analytics

We use Google Analytics (GA4) to understand general traffic trends, popular pages, referral sources, and device/browser compatibility. Google Analytics collects anonymized, aggregated information (such as browser type, time spent on site, and approximate geographic region).

This analytics data never includes your calculator inputs or personal health information. You can opt out of Google Analytics tracking at any time by installing the Google Analytics Opt-out Browser Add-on.

5. Advertising & Third-Party Cookies

To maintain our calculators as free educational resources, we may display advertisements served by third-party advertising partners, including Google AdSense.

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on visits to our site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting:

• Google Ads Settings
• Digital Advertising Alliance (DAA) Opt-Out Page
• Network Advertising Initiative (NAI) Consumer Opt-Out

6. Communications & Contact Form

If you choose to submit a message via our Contact page, the details provided (name, email address, message) are securely routed through FormSubmit (formsubmit.co) solely to allow our team to reply to your inquiry. We do not use your email address for unsolicited marketing or sell it to third parties.

7. GDPR & CCPA Privacy Rights

Under data protection regulations such as the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), users have rights to data access, transparency, and opting out of data sale/profiling. Because Health Fitness Calculator does not collect, store, or sell personal identifiers or calculator logs, no database of user records is retained.

8. Policy Revisions

We may periodically update this policy to reflect new web features or regulatory requirements. Any modifications will be posted directly to this page with an updated timestamp.
