Privacy Policy
Last updated: 6/7/2026
This Privacy Policy describes how BuildCalcs ("we", "us") collects, uses and shares information when you visit our website.
Information we collect
BuildCalcs is read-only. We do not require an account and we do not store the values you type into our calculators — all calculation happens in your browser. We collect standard server logs (IP address, browser type, referring URL, timestamps) for security and traffic analysis.
Cookies & analytics
We may use first-party cookies and privacy-respecting analytics to understand which calculators are most useful. These cookies do not identify you personally.
Advertising
BuildCalcs is supported by third-party advertising (such as Google AdSense or Ezoic). These networks may use cookies and similar technologies to serve ads based on your prior visits to our site or other sites. You can opt out of personalized advertising via your Google Ad Settings or via aboutads.info.
Lead-generation partners
If you click a "Get free quotes" button and submit information to a partner network, that information is governed by the partner's privacy policy. We may receive a referral fee for these introductions.
Your rights
If you are in the EU, UK or California, you have the right to access, correct or delete personal data we hold about you, and to object to or restrict processing. Contact us using the details on our Contact page.
Changes
We may update this policy from time to time. Material changes will be flagged on this page with a new "Last updated" date.
