Privacy Policy - Coast FIRE Calculator
Introduction
Coast FIRE Calculator (coastfirecalc.net) is a free financial calculator that runs entirely in your browser. This policy explains what little data is involved and how it is handled. It reflects how the site actually works today.
The short version
- There are no user accounts — you never sign up, and we never ask for your name or email to use the calculator.
- The numbers you type into the calculator (age, savings, expenses, and so on) are processed only in your browser. They are never transmitted to or stored on our servers.
- We do not sell or trade any data.
Information handled
-
Calculator inputs
- What: The financial figures you enter (age, retirement age, expenses, returns, etc.).
- How it is handled: All calculations run locally in your browser. These inputs are not sent to our servers and are not stored by us. If your browser saves anything (for example, to remember your last inputs), it stays on your own device.
-
Local browser storage
- What: Preferences such as your last calculator settings or theme may be kept in your browser's local storage.

Aggregate usage analytics
- What: Standard, aggregated analytics about how pages are used (page views, device type, approximate region).

-
Cookies
- Cookies or similar technologies may be used for analytics and, if and when advertising is enabled, for advertising. You can control cookies through your browser settings and any consent controls shown on the site.
Advertising
The site may display advertising to keep the calculator free. Any advertising is subject to the ad provider's own cookie and data practices, which you can review with that provider. This section is kept accurate as advertising is enabled.
Data sharing
We do not sell, trade, or rent personal information. Aggregated, non-identifying analytics may be processed by standard third-party analytics or advertising providers under their own privacy policies. We may disclose information only where required by law.
