No account. No server. No analytics SDK. Everything is computed on-device — App Privacy label: "Data Not Collected".
How we calculate
Real actuarial science, not vibes.
Yorick starts from official mortality data: the U.S. Social Security Administration period life tables, adjusted with United Nations life-expectancy data covering 234 countries and territories, so your baseline matches where you actually live.
Your ~20 lifestyle answers then shift that baseline using effect sizes taken from named, peer-reviewed studies — never invented multipliers. Every adjustment in the app shows its citation, so you can check our work.
