Terms of Service

Last updated: June 16, 2026

Acceptance of Terms

By accessing and using FitCalCalc.com (the "Site"), you accept and agree to be bound by these Terms of Service. If you do not agree with any part of these terms, please do not use the Site.

Description of Service

FitCalCalc provides free, web-based fitness and nutrition calculators including but not limited to: TDEE (Total Daily Energy Expenditure) calculator, macro nutrient calculator, BMI (Body Mass Index) calculator, 1RM (One Rep Max) strength calculator, body fat percentage estimator (US Navy circumference and Jackson-Pollock skinfold methods), meal plan calorie distribution generator, and body measurements tracker. All calculations are performed client-side in your browser.

Medical & Fitness Disclaimer

FitCalCalc is not a medical device, medical professional, registered dietitian, or certified personal trainer. The calculators on this Site provide estimates based on mathematical formulas and publicly available scientific research. These estimates:

• Are for informational and educational purposes only
• Do not constitute medical advice, diagnosis, or treatment
• Should not replace consultation with qualified healthcare professionals
• May not be accurate for individuals with specific medical conditions, pregnancy, eating disorders, or other health concerns

You should always consult a licensed physician, registered dietitian, or certified fitness professional before:

• Starting any weight loss or diet program
• Beginning a new exercise or strength training regimen
• Making significant changes to your calorie intake or macro nutrient ratios
• Attempting maximum weight lifts or 1RM testing
• Using body fat percentage estimates as a substitute for DEXA, hydrostatic weighing, or other clinical body composition assessments
• Following meal plan calorie distributions without verifying against your individual dietary needs and medical history

Body Fat Estimation Disclaimer

The US Navy circumference method and Jackson-Pollock 3-site skinfold method provide estimates only. These methods have documented error margins (circumference: ~3-5%; skinfold: ~3% when performed by trained professionals). Results should not be used to diagnose obesity, eating disorders, or any medical condition. For clinical body composition assessment, consult a healthcare provider for DEXA, hydrostatic weighing, or Bod Pod testing.

Meal Plan & Nutrition Disclaimer

The meal plan generator distributes calculated calorie and macro targets across meals using general metabolic principles. It provides sample food suggestions only and is not a personalized nutrition plan. Meal plans do not account for food allergies, intolerances, medical conditions (diabetes, kidney disease, etc.), cultural dietary restrictions, or medication interactions. Always consult a registered dietitian for personalized nutrition advice.

Body Measurements Disclaimer

Body measurement data is stored locally in your browser's localStorage and is never transmitted to our servers. While we calculate waist-to-hip ratio (WHR) and provide WHO-based health risk categories, these are screening tools only. They do not constitute a medical diagnosis. Self-measured values may differ from clinical measurements.

No Professional-Client Relationship

Use of this Site does not create a doctor-patient, dietitian-client, trainer-client, or any other professional relationship between you and FitCalCalc or its operators. No information on this Site should be construed as establishing such a relationship.

Accuracy of Calculations

While we use scientifically validated formulas (Mifflin-St Jeor, Harris-Benedict, Epley, Brzycki) and strive for accuracy, all calculator outputs are estimates. Factors affecting actual results include but are not limited to:

• Individual metabolic variations
• Body composition differences (muscle-to-fat ratio)
• Hormonal factors and medical conditions
• Medication effects on metabolism
• Accuracy of self-reported activity levels
• Form and technique in strength training

Limitation of Liability

To the fullest extent permitted by applicable law, FitCalCalc and its operators, affiliates, and contributors shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising from or related to your use of, or inability to use, the Site or its calculators. This includes but is not limited to:

• Injuries sustained during exercise or strength training based on 1RM estimates
• Nutritional deficiencies or health problems resulting from dietary changes based on macro calculations
• Any decisions made based on information provided by the Site
