Privacy

Short version: everything you type into ConcreteCalc stays on your device.

Calculations are local

Every calculator on this site runs in your browser with client-side JavaScript. Your dimensions, volumes and prices are never sent to a server, saved to an account or stored in cookies by this site. Close the tab and the numbers are gone.

What is collected

Like most websites, this site is served through a hosting platform that keeps standard technical logs (such as IP address and browser type) for security and reliability. Those logs contain nothing you entered into a calculator. The site sets no advertising cookies and runs no cross-site trackers.

External links

Pages link to sibling calculators in the same free-tools family. Once you follow a link elsewhere, that site’s privacy practices apply.

Changes

If this policy ever changes in a way that affects what happens to your input, the change will be posted on this page before it takes effect.
