Privacy Policy

1. Introduction & Scope

Welcome to CoolHeat Sizer ("we," "our," or "us"). CoolHeat Sizer is a lightweight, offline mobile application that helps users estimate cooling capacity (BTU/h) and heating power (kW) based on room size and simple user-selected factors.

We respect your privacy and are committed to protecting it. This Privacy Policy explains what information we collect (if any), how we use it, and your choices when using the CoolHeat Sizer mobile app and any related pages we operate.

2. Information We Collect

CoolHeat Sizer is designed to function without collecting personal information and without requiring account creation.

• Information You Provide: Any values you enter (such as room area in m², insulation level, or sun exposure) are used only to calculate results inside the app. This information is not sent to us and is not stored on external servers.
• Location Data: CoolHeat Sizer does not request or access your GPS location and does not track your location.
• App Usage Data / Tracking: CoolHeat Sizer does not collect analytics, advertising identifiers, or tracking data. We do not profile users and we do not track your activity across apps or websites.
• Local Preferences (On-Device Only): The app may store basic preferences locally on your device (for example: selected units, theme mode, or default options) to improve usability. This data remains on your device unless you clear the app data or uninstall the app.
• Automatically Collected Data by Platforms: Your device or app store provider (such as Google Play) may collect standard technical information required to distribute and maintain the app. This data is handled by those platforms, not by CoolHeat Sizer.

3. How We Use Information

Since CoolHeat Sizer does not collect personal information during normal usage, we do not use personal data for advertising, tracking, or profiling.

Any locally stored preferences (such as units or theme) are used only to:

• Remember your settings for convenience.
• Provide a consistent user experience.
• Maintain app functionality and performance.

4. Cookies and Tracking

CoolHeat Sizer (mobile app): The app does not use cookies or tracking technologies.

Website pages (if applicable): If this Privacy Policy is accessed through a website, that site may use essential cookies required for basic functionality (such as session handling). These cookies are not used for advertising or behavioral tracking.

6. Sharing of Information

We do not sell, rent, or share personal information with third parties. Since CoolHeat Sizer does not collect personal information during normal usage, there is generally no data to share.

Information may be disclosed only if required by law or to protect our legal rights and users’ safety.

7. Data Retention & Security

CoolHeat Sizer does not store personal information on external servers. Any preferences saved by the app are stored locally on your device and can be cleared at any time by clearing the app’s data or uninstalling the app.

We apply reasonable safeguards to protect information, but no method of electronic storage is completely secure.

8. Children's Privacy

CoolHeat Sizer is intended for a general audience. We do not knowingly collect personal information from children.

9. Your Rights

Depending on your jurisdiction, you may have rights to access, correct, or delete personal information. Since CoolHeat Sizer does not collect personal data for normal usage, many of these rights may not apply.

You may clear locally stored preferences at any time by clearing the app data or uninstalling the app.

10. Disclaimer

CoolHeat Sizer provides estimates based on general HVAC rules of thumb. Results may vary depending on room layout, insulation, equipment efficiency, and other real-world factors. For critical sizing decisions or large spaces, consult a qualified HVAC professional.

11. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page and reflected by an updated “Last Updated” date.
