Common questions
Is Longlevity really free?
Yes. Your estimated lifespan, your biological age, your #1 lever with its real number, the 160+ habit library, unlimited re-measures, sharing, and comparing with people you love: all free, no card, no trial clock. The full report is optional.
What's in the report?
Your personal depth: every lever ranked with the years it is worth to you, your per-habit biological-age breakdown, your ten-year projection, and your priorities with exact next moves. It is a single $19 purchase for the full analysis of one measurement: a dated document, delivered to your email as a permanent link that opens on any device, yours forever. See an example report.
Is it a subscription?
No. The report is a one-time purchase and we never charge you automatically. There is nothing to cancel. Re-measuring stays free forever, and your report stays yours forever. Once a year we may invite you to buy a fresh year-over-year analysis of your newest measurement; that is a separate choice, never a charge.
What if I change my mind?
Simple: a full money-back window of 30 days. Use the link in your report email, or Request a refund from your account, and Stripe processes it. Your saved data is always kept.
Does Longlevity get more accurate over time?
Yes. The model is versioned and we review it against new research every month. When the science moves, the engine moves with it. And because we keep your original answers, your whole history is re-scored under the latest model. Even your past check-ins get more accurate. (Your report itself does not change: it is the analysis of one measurement, exactly as written on its date.)
Do you sell my data?
No. We never sell your personal information. Your assessment answers are used to produce your results and nothing else. See our privacy commitment.
