ConcreteCalc — Privacy Policy

Introduction

Top 7 Systems ("we", "our", or "us") operates the ConcreteCalc mobile application. This Privacy Policy explains how we handle your information when you use our app.

Data Collection — We Keep It Simple

ConcreteCalc is a standalone calculator that runs entirely on your device. We have designed it with your privacy as a priority:

• No account required. You can use every feature without signing up or providing any personal information.
• No personal data collected. We do not collect your name, email, phone number, or location.
• No analytics or tracking. We do not use third-party analytics SDKs or advertising frameworks.
• No network requests. The app works fully offline. Your calculations never leave your device.

Data Storage

All data you enter — calculations, project totals, cost settings, and preferences — is stored locally on your device using Apple's standard on-device storage. This data is included in your iCloud device backups if you have backups enabled.

We never upload, transmit, or store any of your data on external servers.

Third-Party Services

ConcreteCalc does not integrate any third-party services, analytics providers, or advertising networks. The only external service involved is Apple's App Store for distribution and updates.

Children's Privacy

Our app does not collect personal information from any user, including children under 13. The app contains no user accounts, social features, or data collection mechanisms.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated revision date. Continued use of the app after changes constitutes acceptance of the updated policy.
