Frequently asked questions
Quick answers about biological age and this calculator.
What is biological age?
Biological age is an estimate of how “old” your body seems compared to your years lived, based on health and lifestyle factors. It is not the same as a clinical diagnosis.
Is this medical advice?
No. BioAgeAH provides educational estimates only. Always consult a qualified healthcare professional for diagnosis, treatment, or before changing medications or exercise.
How accurate is the score?
Accuracy depends on honest answers and the limits of any questionnaire model. Blood biomarkers and professional assessments can refine estimates; this tool is a starting point for reflection.
Do you store my answers?
By default, calculations run in your browser session. See our Privacy Policy for how hosting (e.g. Vercel) may process technical data such as IP or logs.
Can I share my result?
Yes. Use the share buttons on the results page. Only share what you are comfortable making public.
