This Privacy Policy explains how FIRE Engine ("we", "us") handles information when you use our FIRE calculator website (the "Site"). By using the Site, you agree to this policy.
The FIRE calculator runs entirely on your device using client-side JavaScript. The financial figures you enter — age, net worth, income, expenses, and rates — are never transmitted to us or stored on any server. When you close or refresh the page, that data is gone.
Like most websites, our hosting provider and analytics may automatically collect standard technical information such as your IP address, browser type, device type, referring page, and pages visited. This is used to understand aggregate traffic and keep the Site secure and functioning.
We may display advertising provided by third-party ad networks. These partners may use cookies, web beacons, or similar technologies to serve ads based on your prior visits to this and other websites, and to measure ad performance.
Third-party vendors, including Google and other ad partners, may use cookies to serve ads based on your prior visits. You can opt out of personalized advertising by visiting Google Ads Settings or aboutads.info/choices.
You can disable cookies in your browser settings and use browser privacy or tracking-protection features at any time. Doing so will not affect the calculator, which works without cookies.
The Site is not directed to children under 13, and we do not knowingly collect personal information from them.
We may update this policy periodically. Changes take effect when posted on this page with a revised "Last updated" date.
