Your inputs, explained.
The calculator runs in your browser. This page explains the data flows in the current version of Concrete Block Calc.
Measurements and calculations
The calculator does not send your form inputs to a calculation API or store them in a website database. JavaScript in your browser computes the estimate. Downloading an estimate creates a CSV file locally; printing uses your browser's print function.
Shared estimate links
The Copy estimate link action puts the calculator inputs in the URL and attempts to copy that URL to your clipboard. Anyone with that link can read its inputs and restore the estimate. URLs may also appear in browser history, hosting request logs or tools used to share the link. Do not put confidential details in a shared estimate.
Hosting and analytics
The website is hosted on Hostinger infrastructure. Loading a page makes normal network requests that may include your IP address, browser details and requested URL. Hosting and access providers operate their own logs and access controls. This version contains no added advertising tags, analytics trackers, account registration form or application database. Provider access features may use their own cookies or sign-in mechanisms.
Contact
If you email contact@concreteblockcalc.com, your email provider and the receiving mail provider process the message. Include only information needed for your question. You can use that address for questions about this page too.
External links and updates
Reference links open other websites that have their own policies. This notice describes the current site's functionality and will need updating if analytics, advertising, forms or other data services are added.
