Privacy Policy for LunarCalendar

Last updated: June 26, 2026

This Privacy Policy describes how LunarCalendar (“we”, “our”, “us”) collects, uses, and protects information when you use our mobile application.

1. Information We Collect

1.1 Information We Do NOT Collect

LunarCalendar is designed with privacy as a core principle. We do NOT collect, store, or transmit the following:

• Personal identification information (name, email, phone number)
• User accounts or login credentials
• Device location data
• Contact information or social media data
• Photos, videos, or media files
• Financial or payment information

1.2 Technical Information for App Updates

When the app checks for updates via our OTA (Over-The-Air) update system, the following technical information is sent to our server:

Data	Purpose
App ID (com.dhpartnerapp.lifestyle)	Identify the application
Platform (Android/iOS)	Provide platform-specific updates
App version & version code	Determine if an update is available
Current bundle version	Compare with the latest version

This information is non-personal, technical in nature, and cannot be used to identify individual users.

1.3 Local Device Storage

The app uses local device storage (AsyncStorage) to save:

• Your preferred language setting
• OTA update version information (current/pending bundle versions)

This data is stored only on your device and is never transmitted to our servers or any third party.

2. How We Use Information

• OTA update data is used solely to check if a newer version of the app is available and to deliver updates.
• Local preferences are used to provide you with a personalized experience (e.g., displaying the app in your chosen language).

3. Data Sharing

We do NOT share, sell, rent, or trade any user data with third parties. The technical information sent for OTA updates is processed only by our own servers and is not disclosed to any external organization.

4. Third-Party Services

LunarCalendar does NOT integrate with any third-party services that collect personal data, including:

• No advertising networks or ad trackers
• No analytics platforms that track user behavior
• No social media SDKs
• No payment processors

5. Data Security

We implement appropriate measures to protect the limited technical data transmitted for OTA updates:

• All OTA update downloads are verified by cryptographic hash (SHA-256) to ensure integrity and authenticity
• OTA check requests are sent over HTTPS in production environments
• No personal data is stored or transmitted, minimizing security risks

6. Children’s Privacy

LunarCalendar is a calendar utility app and is not directed at children under 13. We do not knowingly collect personal information from children. Since we do not collect personal data from any users, this policy inherently protects children’s privacy.

7. Data Retention

Since we do not collect personal data, there is no personal data to retain. Technical OTA check data is processed in real-time and is not stored on our servers beyond the immediate request-response cycle.

8. Your Rights

Because LunarCalendar does not collect personal data, there are no personal data requests to fulfill. If you wish to clear your local preferences, you can:

• Change your language setting at any time within the app’s Settings screen
• Reset app data by clearing the app’s storage in your device’s system settings

9. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last updated” date. We encourage you to review this policy periodically.
