Privacy Policy

Short version: your dimensions never leave your browser. Every calculation on this site runs locally on your device — there is no server that receives your slab size, no account to create, and no result to store. This page describes the whole picture, including the few cases where anything at all is collected.

What we collect

• Calculator inputs and results: nothing. They are computed in your browser and never transmitted.
• Contact email: if you email us, we receive your address and message, and use them only to reply. We don't add you to any list.
• Server logs: like nearly every website, the hosting provider keeps short-lived technical logs (IP address, pages requested, timestamps) for security and abuse prevention.

Analytics and advertising

If privacy-respecting, aggregate analytics are added later (for example Plausible or Google Analytics), or if advertising appears, this section will be updated before that happens with the exact provider and what it records. As of the date above, no analytics or advertising scripts run on this site.

Cookies

The site sets no cookies and uses no local storage for tracking. Your preferences (like the price you enter in a calculator) live only in the page for as long as it's open.

Third-party pages

Our pages link to external sites (suppliers, references). Once you follow a link off this site, that site's own policy applies — this page covers only concretemixcalc.com.

Changes and contact

Material changes to this policy will be reflected in the date at the top. Questions about privacy go to the contact page.
