Easy Solution Lab (“we,” “our,” or “us”) respects your privacy. This Privacy Policy explains how the HVAC CFM Calculator mobile application (“App”) handles information when you use our services.

1. Information We Collect

HVAC CFM Calculator is designed to help users perform HVAC, airflow, ventilation, and CFM calculations.

Calculation inputs: Room dimensions, duct measurements, airflow values, air changes per hour (ACH), and other values entered into calculators may be processed to provide results.

Saved calculations and preferences: The App may store saved calculations, measurement preferences, and settings locally on your device.

Automatically collected information: If advertising or analytics services are integrated, those services may collect information such as device identifiers, app interactions, diagnostic data, and approximate location derived from IP address, subject to their own privacy policies.

We do not intentionally request your name, phone number, contacts, or precise location to perform HVAC calculations.

2. How We Use Information

Information is used to:

Calculate CFM, airflow, ventilation, and related HVAC values.

Save your calculations and measurement preferences.

Improve the App’s functionality, performance, and reliability.

Display advertisements, if advertising services are enabled.

Identify and resolve technical issues.

3. Data Storage and Security

Calculation inputs may be processed on your device. Saved calculations and preferences may be stored locally.

We do not claim that all information is stored exclusively on your device if third-party advertising, analytics, or other online services are integrated. We take reasonable measures to protect information handled by our App, but no method of electronic storage or transmission is completely secure.

4. Third-Party Services and Advertising

The App may use third-party services, such as Google AdMob, Google Play Services, or analytics tools, if implemented in the published version.

These providers may collect or process certain information to deliver their services, prevent fraud, measure advertising performance, or diagnose technical problems.

5. Data Sharing

We do not sell users’ personal information.

We do not intentionally share calculation inputs with third parties for their independent use. However, information may be processed by third-party service providers when necessary to provide advertising, analytics, security, or technical services, if those services are integrated.

We may also disclose information when required by applicable law or to protect our legal rights and users’ safety.

6. Children’s Privacy

HVAC CFM Calculator is a general-purpose utility app and is not specifically designed to collect personal information from children.

We do not knowingly collect personal information from children. If you believe that a child has provided personal information through the App, please contact us so we can review the matter and take appropriate action.

7. Data Retention and Deletion

Locally stored calculations and preferences may remain on your device until you delete them, clear the App’s data, or uninstall the App.
