Privacy Policy
Last updated: June 28, 2026
Best Fire Calculator ("we", "us", or "the site") is committed to protecting your privacy. This policy explains what information is and isn't collected when you use bestfirecalculator.com. In short: the calculator runs entirely in your browser, and we do not collect or store the numbers you enter.
Your calculator inputs stay on your device
Every calculation — your age, savings, income, spending, and any other figures — is processed locally in your web browser. This data is never transmitted to, or stored on, our servers. We have no account system and no database of user inputs.
Local storage
We use your browser's local storage for one small convenience: remembering your light/dark theme preference. This information stays in your browser and is not sent to us. You can clear it at any time through your browser settings.
Shareable links
When you use the "Share" feature, your scenario is encoded directly into the page link itself — not uploaded to a server. Anyone you send that link to can view the scenario it contains, so only share it with people you trust.
Hosting and server logs
The site is served as static files by our hosting provider. Like virtually all web hosts, the provider may automatically log standard technical request data (such as IP address, browser type, and pages requested) for security and reliability purposes. We do not combine this with any personal information, because we don't collect any.
Third-party links
Our pages may link to external websites. We are not responsible for the privacy practices or content of those sites; we encourage you to review their privacy policies.
Children's privacy
This site is intended for a general adult audience and is not directed at children under 13. We do not knowingly collect personal information from anyone, including children.
Changes to this policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
