Frequently Asked Questions

#QuestionAnswer
1Is my data stored or sent anywhere?No. Everything runs 100% in your browser using JavaScript. The ages and answers you enter are never uploaded, saved or tracked, so there is zero data retention.
2How is the 10-year longevity score calculated?About half of the score comes from how well your finances, family and lifestyle values match. The rest comes from your conflict-resolution styles, the age gap and how many years you have already built trust together.
3Can this calculator predict divorce or breakup?No. It is an educational and entertainment tool, not a prediction. Real marriages depend on communication, respect and effort, and couples who feel stuck can benefit from a counselor or relationship workshop.
4Why do years together and the age gap matter?More years together usually mean more shared experience and proven trust, so they add to the score up to the 10-year mark. A larger age gap can mean different life stages, which slightly lowers the score.
5How do the shareable links work?After you calculate, the page builds a link with both ages and the score, like ?y=28&p=30&s=82. Anyone who opens it instantly sees your result card, without your other answers.
