This site does not collect personal information. The calculators run entirely in your browser. No inputs you enter are sent to a server or stored anywhere.
There is no account system, no newsletter signup, and no email capture. The only data this site stores in your browser is a theme preference (light or dark) and whether you have seen the intro animation, both in localStorage, both cleared when you clear your browser data.
This site may use basic analytics to understand traffic (page views and referrer information). No personally identifiable information is collected or stored. No data is sold or shared with third parties for advertising.
