Privacy policy
Effective July 15, 2026.
What we collect
Calculator inputs are processed entirely in your browser — dimensions, prices and results are never transmitted to or stored on our servers. If you subscribe to the newsletter, we store the email address you provide, used solely to send the updates you requested.
Analytics & cookies
We use privacy-respecting, aggregate analytics to understand which pages are useful (page views, referrers, country-level location). We do not build individual profiles, and we do not sell or share visitor data with third parties. Functional cookies, where used, exist only to remember interface preferences.
Third-party links
Guides link to external standards bodies and references (ASTM, ACI, government sites). Their privacy practices are their own; this policy covers only materialscalc.com.
Your rights & contact
You can unsubscribe from the newsletter with one click at any time, and you may request deletion of your email address by writing to hello@materialscalc.com. Material changes to this policy will be dated at the top of this page.
