Welcome to HVAC Pro Toolkit. Your privacy is important to us. This Privacy Policy explains how our application handles user information.

1. Overview

HVAC Pro Toolkit is an offline mobile application designed to provide HVAC calculation tools, reference data, and professional utilities for technicians and engineers.

The app is designed to function without requiring an internet connection, and we prioritize user privacy.

2. Information We Collect

HVAC Pro Toolkit does not collect, store, or share any personal information.

We do not collect:

• Personal details (name, email, phone number)
• Location data
• Device contacts
• Photos or media files
• Background usage data

The app works fully offline and does not transmit user data to any server.

3. Permissions

The app may request minimal device permissions strictly for functionality purposes (if applicable), such as:

• Storage access (for saving calculation results locally on your device)
• Device access for proper app performance

We do not access or transmit any data externally.

4. Data Storage

All data entered into HVAC Pro Toolkit (such as calculations or saved values) is stored locally on your device only.

We do not have access to your stored data.

If you uninstall the app, all locally stored data may be deleted from your device.

5. Third-Party Services

HVAC Pro Toolkit does not use third-party analytics, ads, or tracking services (if applicable — adjust if you plan to use ads like AdMob).

If future versions include third-party services (such as advertisements or analytics), this Privacy Policy will be updated accordingly.

6. Children’s Privacy

HVAC Pro Toolkit is intended for professional use and is not specifically directed toward children under 13 years of age.

We do not knowingly collect any personal data from children.

7. Data Security

Since the app operates offline and does not transmit personal information, the risk of data exposure is minimized.

Your device security settings are responsible for protecting locally stored data.

8. Changes to This Policy

We may update this Privacy Policy in the future.

Any updates will be reflected by revising the “Last Updated” date above.
