Privacy Policy

FirewoodCalc.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.

When you click a product link on this site and make a purchase on Amazon, we may earn a small commission at no additional cost to you. These commissions help us maintain the site and keep all of our calculators and reference tools free to use.

We only recommend products we believe are genuinely useful for people who heat with wood. Our product suggestions are based on practical experience and user needs, not on commission rates. Affiliate relationships never influence the data or calculations presented on this site.

This site displays advertisements served by Google AdSense. Google uses cookies to serve ads based on your prior visits to this site and other websites. You can opt out of personalized advertising by visiting Google’s Ad Settings.

Third-party ad vendors, including Google, use cookies to serve ads based on your browsing history. You may opt out of third-party vendor cookies for personalized advertising at aboutads.info.

We use Google Analytics 4 to understand how visitors use the site — which pages are popular, how people navigate between tools, and where traffic comes from. This helps us improve the site and prioritize new features.

Google Analytics collects anonymous usage data including page views, session duration, approximate geographic location (country/region level), device type, and browser. It does not collect your name, email address, or any personally identifiable information.

You can prevent Google Analytics from collecting your data by installing the Google Analytics Opt-out Browser Add-on.

FirewoodCalc does not require accounts, logins, or registrations. We do not collect your name, email address, phone number, or any personal information.

All calculator inputs (zip code prefix, home size, wood species selections) are processed entirely in your browser. This data is never transmitted to our servers or stored anywhere. When you close the page, it is gone.

The only cookies on this site come from Google Analytics and Google AdSense, as described above. We do not set any first-party cookies.

This site contains links to Amazon.com and other external websites. We are not responsible for the privacy practices or content of those sites. We encourage you to review their privacy policies before providing them with any personal information.

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated revision date at the top. Your continued use of FirewoodCalc after changes are posted constitutes acceptance of the updated policy.

If you have questions about this privacy policy or how the site handles data, reach out to us at privacy@firewoodcalc.com.
