2. Medical Disclaimer
BioSync Lab is an educational and informational tool only. The calculators, scores, and analyses provided on this website do not constitute medical advice, diagnosis, or treatment. The information is derived from peer-reviewed scientific literature and mathematical models, but it is not a substitute for professional medical judgment.
You should always consult a qualified healthcare professional before making any changes to your diet, exercise routine, supplementation, or health regimen based on the results provided by our tools.

3. Use of Tools
BioSync Lab provides biometric calculators — including VO2 Max Estimator, Basal Metabolic Rate, Biological Age Proxy, Heart Rate Zones, Body Fat Estimator, Protein Intake Optimizer, Sleep Debt Recovery, and Electrolyte Replenishment — that generate estimates based on established scientific formulas and published research.
Results are approximations and may vary depending on individual physiology, genetics, and environmental factors. BioSync Lab does not guarantee the accuracy, completeness, or clinical applicability of any calculation. These tools should be used as supplementary reference points, not as definitive clinical assessments.

We do not transmit, store, or collect any personal health data on our servers. Your data never leaves your device.
