Privacy Policy
BuildWise Calculators respects your privacy. We do not collect or store any personally identifying information. All calculations run client-side in your browser; the inputs you enter are never transmitted to our servers.
We use standard web analytics (page views, session counts, referrer source) to understand which calculators are most useful and to improve the site. We do not track you across other websites.
We display advertising on some pages from third-party ad networks (Mediavine or Raptive). These networks may set cookies for ad personalization. You can opt out of personalized advertising through your browser’s privacy settings or the network’s opt-out page.
Outbound affiliate links to retailers and contractor matching services may set cookies on the destination site. We disclose affiliate relationships per FTC guidelines. Affiliate revenue does not influence the calculations or recommendations on this site.
