Overview

ConcreteMix Pro is an offline-first concrete quantity, mix and cost calculator for contractors, builders and owner-builders. It also includes local project locations, material order PDFs and pour progress tracking. The app is designed to work without an account, backend server or cloud sync.

Information We Collect

We do not collect personal information through ConcreteMix Pro. The app does not require login, registration, cloud storage or a user account.

Project names, locations, notes, calculator values, material prices, Material row selections, order status for cement, sand, stone, additive or ready-mix, pour progress percentages and settings are stored locally on your device or in your browser storage so the calculator can work offline.

Local Storage

ConcreteMix Pro uses local device storage only. Saved projects and settings remain on the device where they were created unless you choose to export a backup file, import a backup file or share a PDF.

Backup export creates a local JSON file containing saved projects, locations, order status, pour progress, settings, costs, custom mixes and saved calculations. You control how that file is moved or shared. Importing a backup replaces the local ConcreteMix Pro data on the device where it is imported.

PDF Export and Sharing

The app can create PDF estimates, progress reports and shopping/order lists from the values you enter and the dashboard rows you select. When you use Save or Share, your device may offer options such as Files, email, messaging apps or nearby sharing. Sharing is controlled by you and by the apps you choose to use.

Internet and Analytics

The calculator is designed to work offline after installation. We do not operate a backend database for calculator data. If analytics or advertising are added in a future version, this policy will be updated before release.
