levin.schwab@gmx.deFrequently asked questions
Is my result really free?
Yes. Your full life-expectancy estimate and your death date are revealed before any paywall, with nothing blurred or held back. The optional Pro purchase only unlocks the what-if levers ("+X years if you…") and the full citation view.
How is my life expectancy calculated?
Yorick starts from a baseline of official mortality statistics: U.S. Social Security Administration (SSA) period life tables for age- and sex-specific mortality, adjusted with United Nations life-expectancy data covering 234 countries and territories so your starting point matches your country.
Your ~20 lifestyle answers then adjust this baseline using effect sizes from named, peer-reviewed research — including Doll & Peto 2004 (BMJ, smoking), Li et al. 2018 (Circulation, combined lifestyle factors), Fadnes et al. 2022 (PLOS Medicine, diet), and the VITAL 2019 trial (NEJM). Each adjustment in the app shows its citation.
The result is a statistical estimate — an average for people with your profile, not a prediction of your individual fate.
What happens to my answers and data?
Nothing leaves your iPhone. Yorick has no account, no server, and no third-party SDKs — everything is computed and stored on-device. Our App Store privacy label is "Data Not Collected". See the full Privacy Policy.
Is this medical advice?
No. Yorick provides statistical estimates for educational and motivational purposes only. It is not medical advice, diagnosis, or treatment. Consult a healthcare professional before making health decisions.
Can I retake the quiz?
Yes, as often as you like. Retaking the quiz recalculates your estimate from your new answers — useful for seeing how a real lifestyle change moves your date. There is no limit and no extra charge.
How do I restore my Pro purchase?
Open Yorick, go to the Pro screen, and tap "Restore Purchases". Make sure you are signed in to the App Store with the same Apple ID you used to buy Pro. Apple processes the restore — no account with us is needed.
I got a new iPhone — will Pro carry over?
Yes. Yorick Pro is a one-time purchase tied to your Apple ID, not your device. Install Yorick on the new iPhone, sign in with the same Apple ID, and tap "Restore Purchases" on the Pro screen. Note that your quiz answers stay on the old device (they are never uploaded), so simply retake the quiz — it takes about two minutes.
