Privacy Policy

How Buildcalchub collects, uses, and protects your information. Short version: we don't collect personally identifiable information, and we don't sell data.

Summary

Buildcalchub is a free educational and reference site with construction calculators. We collect standard anonymous web analytics (page views, time on site, approximate location), display Google AdSense advertising, and use cookies for both. We do not collect personally identifiable information (PII) unless you voluntarily contact us via email.

Information We Collect

Automatically Collected

  • IP address (anonymized) — for analytics and fraud prevention
  • Browser type and version — for compatibility diagnostics
  • Device type (desktop, mobile, tablet) — for responsive design
  • Page URLs visited — for analytics
  • Time on page, scroll depth — for content quality measurement
  • Approximate geographic location (country, state level) — for regional content variations
  • Referring URL — how you found us

Voluntarily Provided

Only if you contact us: name, email, message content. Used solely to respond to your inquiry.

How We Use Information

  • Operate and improve the site
  • Analyze traffic and user behavior (aggregated, non-identifying)

We Do Not:

  • Sell your data to third parties

Cookies and Tracking

Buildcalchub uses the following cookies:

  • Google Analytics (GA4) — anonymous user analytics, 14-month retention
  • Google AdSense — ad serving and frequency capping
  • Session cookies — for basic site functionality (30 minute timeout)

You can disable cookies in your browser settings. Calculators will still work; analytics and personalized ads will not.
