How CoastFIRE.org collects, uses, and protects information
Last updated: September 21, 2026
This Privacy Policy explains how CoastFIRE.org ("we," "us," "our," or the "Site") handles information when you visit and use our free financial calculators. We built these tools to be usable without creating an account, and we try to collect as little personal information as possible.
All of our calculators (Coast FIRE, FIRE, Retirement, Investment, and SWR / 4% Rule) run entirely in your web browser. The numbers you type into a calculator β such as your income, savings, age, or expenses β are never transmitted to our servers, stored in a database, or seen by us. When you close the tab, that data is gone.
Like most websites, our servers and third-party tools may automatically collect some technical information when you visit, including:
This information is used only in aggregate, to help us understand how the Site is used and to improve it. It is not used to personally identify you.
Cookies are small text files stored on your device. We (and third parties we work with, such as Google) may use cookies and similar technologies for the following purposes:
You can disable cookies through your browser settings at any time. Doing so may affect some features of the Site.
We use, or intend to use, Google AdSense to display advertising on this Site. Google, as a third-party vendor, uses cookies (including the DoubleClick DART cookie) to serve ads based on your visits to this Site and other sites on the internet.
For more information on how Google uses data when you use our Site, see "How Google uses information from sites or apps that use our services".
Our Site may contain links to other websites. We are not responsible for the privacy practices or content of those third-party sites. We encourage you to review the privacy policy of any site you visit.
This Site is not directed at children under the age of 13, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to delete it.
Depending on where you live, you may have rights under data protection laws such as the GDPR (EU/UK) or CCPA (California), including the right to know what data is collected about you, request deletion, or opt out of the sale of personal information. Because we do not require accounts or collect personal financial data through our calculators, we hold very limited personal data. For any requests related to analytics or advertising data, please use the opt-out tools listed in Section 4, or contact us using the details below.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date.
