Privacy Policy

Last updated: April 29, 2026

This Privacy Policy explains how CDMDEV collects, uses, and protects information when you use the Bitumen Calculator application.

1. Information We Collect

Bitumen Calculator is designed to operate with minimal data collection. The app may process:

• Local usage data (for example, calculation history and preferences) stored on your device.
• Advertising identifiers and technical signals only when ads are shown, through third-party providers.

2. Advertising (Google AdMob)

The app may display ads through Google AdMob. AdMob may collect and process data under its own policies for personalization, measurement, and fraud prevention.

3. Consent

Where legally required (for example, in regions with privacy regulations), the app may request your consent for ads through Google's User Messaging Platform (UMP).

4. How We Use Information

Information is used to:

• Provide and improve app functionality.
• Save your app settings and preferences.
• Display and measure ads when applicable.
• Comply with legal obligations.

5. Storage and Security

Functional app data (such as history and settings) is stored locally on your device. We apply reasonable safeguards to protect information, but no method is 100% secure.

6. Sharing with Third Parties

We do not sell personal data. We only share information strictly necessary with technology providers to operate features such as advertising and technical analytics, under their own terms.

7. User Rights

You can limit ad-related data usage from your device settings and, where applicable, manage ad consent according to your local regulations.

8. Changes to This Policy

This policy may be updated to reflect legal or app functionality changes. The latest version will always be available at this same URL/file.
