Calculator inputs
The numbers you enter into the calculator (initial investment, contribution amount, time horizon, and assumed return) are processed in your browser to produce your results. Calculator inputs are not required to be sent to or stored on our servers to produce a result.
Analytics
We may use privacy-conscious analytics to understand aggregate site usage, such as which pages are visited and general traffic trends, in order to improve the site. This is used in aggregate and is not intended to identify individual visitors.
Cookies
The site may use a small number of cookies for basic functionality and analytics. You can control or disable cookies through your browser settings; doing so should not prevent the calculator itself from working, since calculations run locally in your browser.
Third parties
We do not sell personal information. If we use third-party analytics or hosting providers, they process data under their own privacy terms in order to provide their service to us.
Changes to this policy
We may update this policy from time to time. Continued use of the site after changes are posted constitutes acceptance of the updated policy.
