⚠️ Important: The health and medical calculators on Chronly are educational tools only. They are not medical devices, not diagnostic tools, and not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider for health concerns.
1. For Educational Purposes Only
All calculators on Chronly that produce health-related estimates — including but not limited to the Biological Age Calculator, Heart Age Calculator, Metabolic Age Calculator, Mental Age Test, Skin Age Calculator, Pregnancy Due Date Calculator, Gestational Age Calculator, and Adjusted Age Calculator — are provided for general educational and informational purposes only.
These tools use population-level statistics and general research findings to produce estimates. They do not account for your individual medical history, genetic factors, medications, existing health conditions, or other factors that a qualified healthcare professional would consider.
2. Not a Medical Device or Clinical Assessment
Chronly's calculators are not:
- FDA-cleared or CE-marked medical devices
- Clinical assessment tools (even if using clinically-named formats)
- Diagnostic instruments
- Screening tools validated for clinical use
Results should not be used to make decisions about your health, medical treatment, medications, diet, exercise, or any other health-related matter without first consulting a qualified healthcare professional.
3. Sources and Research Basis
Where our calculators cite published research (e.g., peer-reviewed journal articles), those citations are provided for transparency and educational context. Citing a study does not mean our implementation of those findings is validated for clinical use. Population-level research findings may not apply to your individual situation.
4. Specific Tool Disclaimers
- Biological Age Calculator: Lifestyle-based estimate only. Cannot assess cellular, epigenetic, or genetic markers.
- Pregnancy Due Date Calculator: EDD estimates only. Ultrasound dating is more accurate. Consult your OB-GYN or midwife.
- Gestational / Adjusted Age: For general reference only; not for clinical decision-making in neonatal care.
- Heart Age / Metabolic Age / Lung Age: Simplified lifestyle estimates; not cardiovascular risk assessments or spirometry measurements.
- Mental Age Test: A fun self-reflection quiz; has no clinical diagnostic validity.
5. Seek Professional Care
If you have concerns about your health, please contact a qualified healthcare provider. Do not delay seeking medical care because of information or results you read on this website. In an emergency, call your local emergency services immediately.
