Privacy Policy

Effective Date: October 27, 2026

Welcome to Home Solar System. We respect your privacy and are committed to protecting the information you share while designing and managing your solar energy projects. This Privacy Policy outlines how we handle data within our mobile application.

1. Information We Collect

Home Solar System is designed to protect user privacy. Most of your project data remains local to your device.

• Location Data: With your permission, the app uses your device's location to determine local solar irradiance, sun path orientation, and optimal roof angles for your solar project calculations. Location data is processed locally on your device or used temporarily to fetch weather/solar data.
• Camera and Photos: If you use spatial, roof-mapping, or visualization features, access to your camera and photo library is required solely for adding visual context or performing project measurements within the app.
• Project & Design Data: Information regarding your energy consumption, roof measurements, panel counts, and project layouts is stored locally on your device.
• Technical & Diagnostic Data: Non-personally identifiable diagnostic logs (such as crash reports and app performance stats) may be collected automatically to help us fix bugs and optimize app performance.

2. How We Use Information

We use the data strictly to provide and improve the core functionality of the app, including:

• Calculating solar energy generation potential and roof capacity.
• Generating local solar project reports and cost estimates.
• Improving app stability, features, and performance.

3. Data Storage & Third-Party Sharing

We do not sell, rent, or trade your personal data with third parties or advertising networks.

• Local Storage: Your solar designs, estimates, and project files are stored on your device.
• Third-Party Services: If the app interacts with external APIs (e.g., mapping, solar irradiation databases, or Apple system services), data exchanged is limited to what is strictly necessary to complete the calculation.

4. Your Choices & Data Rights

You have full control over your data within the application:

• Permissions: You can grant or revoke Location, Camera, and Photo permissions at any time via your iOS Device Settings.
• Data Deletion: Deleting a project within the app removes it permanently from your device storage. Uninstalling the app completely removes all locally stored project data.

5. Security

We prioritize the security of your data by leveraging native iOS security frameworks and minimal cloud data reliance to ensure your solar designs remain private.

6. Changes to This Policy

We may update our Privacy Policy from time to time. Any changes will be posted directly on this page with an updated "Effective Date".
