Privacy Policy

Last updated: April 5, 2026. This policy explains how Concrete Calculator handles data when you use the mobile app and this support site.

Data We Collect

Basic app activity and crash diagnostics when analytics or crash reporting is enabled.
Ad interaction data if Google AdMob is active in the production release.
Information you voluntarily share through third-party storefront or browser interactions, such as review text or page visits.

How We Use It

To improve app stability and fix calculation or UI issues.
To understand which features are used most often, such as slab, footing, or project history flows.
To operate advertising in supported screens where allowed by the app design.

Third-Party Services

Google AdMob may process advertising and device-related signals.
Google Firebase may process analytics and crash reporting data.

Data Retention

Local calculation history is stored on the device unless you delete it inside the app or remove the app. Third-party service retention is governed by the provider's own policies.

Children's Privacy

Concrete Calculator is not directed to children under 13. If you believe a child provided personal information through support channels, contact the relevant platform provider so the request can be reviewed.
