What we collect

Dayswise's calculators run entirely in your browser or are computed on our server from the date you request. We do not require an account, and we do not ask you to submit personal information to use any calculator on this site. Specifically: any date of birth you enter into our age, longevity, life-expectancy, or "time remaining" calculators is processed only in your browser and is never sent to our servers, stored, or shared.

Analytics

We use privacy-respecting, first-party web analytics (Vercel Web Analytics and Speed Insights) to understand aggregate traffic and performance, for example which pages are popular and how quickly pages load. This does not use third-party cookies and does not track you across other websites.
