Overview

Body Numbers ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our website at body-numbers.com (the "Service").

The short version: All fitness calculations are performed locally in your web browser. We do not collect, store, or transmit any personal health data you enter into our calculators.

Information We Do NOT Collect

We want to be clear about what we do not collect:

  • Health and fitness data you enter into our calculators (weight, height, measurements, etc.)
  • Calculator results (BMI, TDEE, body fat percentage, etc.)
  • Personal identification information (names, email addresses, phone numbers)
  • Account credentials (we don't have user accounts)

All calculations are performed entirely within your web browser using client-side JavaScript. No data is sent to our servers or any third party.
