What this concrete calculator privacy page covers
Concrete Calculator (GoConcreteCalc) at goconcretecalc.com is a free planning calculator for concrete volume, bags, weight, mix ratios, gravel, and blocks. You do not create an account to use it. This concrete calculator privacy notice explains what stays on your device and what never leaves the browser unless you enable optional analytics.
Data that stays in your browser
Job totals and region preferences are stored in session storage on your device so you can add pours while you plan. Clearing the browser session removes them. Homepage reviews you submit are saved in local storage on that same device only. We do not receive those measurements or reviews on a server as part of the calculator itself.
Optional analytics
If a site operator sets NEXT_PUBLIC_GA_MEASUREMENT_ID, Google Analytics 4 may load. Without that environment variable, no GA script is injected. Search Console verification uses NEXT_PUBLIC_GSC_VERIFICATION when configured.
