The Coast FIRE Calculator (“we”, “our”, “the site”) operates thecoastfirecalculator.com. This policy explains what data the site handles and the choices you have. Last updated 2026-09-30.
The calculator runs entirely in your browser. Your age, assets, spending, savings, and assumptions are processed locally and are never uploaded, stored, or transmitted to our server. Nothing you type into the calculator is collected by us.
The site uses a small number of cookies to remember your consent choices and to keep the site working. These are managed through the consent banner (Accept All, Reject All, Customize) and can be changed at any time via the Cookie Policy page.
We measure aggregate visits using self-hosted Umami and Google Analytics 4. These tools are loaded only after you accept analytics cookies, and they report page-view statistics — not your calculator inputs. Analytics data is used to understand which pages are useful and to keep the site running reliably.
The optional sign-in uses Google as an external identity provider (via SSO). If you choose to sign in, Google shares only the profile information needed to identify you; we do not receive or store your Google password.
We do not sell, rent, or trade personal data. Because the calculator collects no inputs and the site has no account system beyond optional Google sign-in, there is no personal data tied to your calculations.
Change or withdraw analytics consent at any time through the cookie banner. Questions about this policy: [email protected].
