Privacy Policy

This Privacy Policy explains how VO2 Max Calculator (the “Site” or “we,” “us,” or “our”) collects, uses, and protects your information when you visit https://vo2max-calculator.com/ or use our free online VO2 Max Calculator tool.

The VO2 Max Calculator is an independent, free web-based tool that estimates your aerobic fitness level (VO2 max) using standard public formulas from common fitness tests such as the Cooper 1.5-mile run, Rockport 1-mile walk, resting heart rate method, and others. It shows your estimated VO2 max in ml/kg/min, along with a fitness category and percentile rank. This tool is not affiliated with, sponsored by, or endorsed by any fitness brands, labs, organizations, or companies. It is provided purely as an informational resource to help users better understand their cardiovascular fitness. All calculations are estimates based on publicly available scientific formulas and the details you enter. For the most accurate results, consult a doctor or get a lab-tested VO2 max measurement.

By using our Site, you consent to the practices described in this Privacy Policy. If you do not agree, please do not use the Site.
