Privacy Policy
Last updated: 7 October 2026.
This policy explains what happens to your data when you use concretecalculatorfree.com.
The numbers you enter
The calculators run in your browser. The dimensions, prices and other numbers you type are not sent to our server and are not saved. The PDF of an estimate is also made in your browser.
Sharing on WhatsApp
If you press the WhatsApp share button, your estimate is passed to WhatsApp or to your device's share menu. We do not receive it. WhatsApp handles it under its own privacy policy.
What is stored on your device
The site stores one item in your browser's local storage: your choice of light or dark theme. It stays on your device. You can remove it by clearing the site data in your browser.
Accounts, ads and analytics
The site has no accounts and asks for no personal details. At this time it shows no ads, uses no analytics service and sets no tracking cookies. This page will be updated before that changes.
Hosting
The site is served by Cloudflare. Like any web host, Cloudflare processes technical request data, such as your IP address and browser type, to deliver the pages and to protect the service.
If you email us, we receive your email address and the content of your message. We use them only to reply.
