Frequently Asked Questions

Is my data safe?

Yes — 100% safe. We collect zero personal data. All calculations happen locally in your browser. Nothing is sent to any server.

How long does the assessment take?

About 10 minutes. There are 31 questions, each with clear, simple options. No medical knowledge required.

Is this a medical diagnosis?

No. This is an educational self-assessment tool. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult your doctor for medical decisions.

What science is this based on?

Every question and recommendation is grounded in peer-reviewed research from journals like NEJM, The Lancet, Science, JAMA, and BMJ, covering 20+ million participants.

What is a longevity score?

A longevity score (0–100) measures how well your habits, biomarkers, and lifestyle support a long, healthy life across 5 science-backed dimensions: Metabolic Baseline, Lifestyle, Sleep, Mind & Social, and Prevention.

How is biological age calculated?

Your biological age is estimated by comparing your total longevity score against your actual age. A higher score suggests your body is aging slower than your calendar age, while a lower score may indicate faster biological aging.

Can I improve my longevity score?

Absolutely. After completing the assessment you'll receive a prioritized action plan with science-backed recommendations organized by timeframe — what to do today, this month, and ongoing — to improve each of your 5 dimensions.
