Privacy Policy

Effective: February 19, 2026

Welcome to Mongle Haru. We respect your privacy and are committed to protecting your personal information. This Privacy Policy explains how we collect, use, and safeguard your data when you use our app.

1. Information We Collect

Mongle Haru is designed with privacy in mind. We do not require you to create an account or provide personal information to use the app.

• Diary Data: All diary entries, stickers, and emotional records are stored locally on your device. This data never leaves your device unless you choose to enable cloud backup.
• Cloud Backup (Optional): If you enable cloud backup, we use Google Drive or Apple iCloud to sync your diary data. We authenticate your Google or Apple account solely for this purpose.
• Advertising Data: We use Google AdMob to display ads. AdMob may automatically collect:
  • Device identifiers (IDFA on iOS, Google Advertising ID on Android)
  • Device information (model, OS version, screen size)
  • IP address and general location
  • Ad interaction data
• Analytics Data: We use Firebase Analytics to collect app usage events such as screen views and feature usage in a non-identifying format.
• Stability Data: We use Firebase Crashlytics to collect crash logs and error diagnostics for service stability.

2. How We Use Your Information

We use the information we collect for the following purposes:

• Cloud Backup: To authenticate your Google or iCloud account and sync your diary data across devices (only if you enable this feature)
• Advertising: To serve personalized or non-personalized ads through Google AdMob and support the app's development
• Analytics: To understand feature usage and improve product quality
• Crash Monitoring: To detect, diagnose, and fix application errors quickly

We do not sell, rent, or share your personal information with third parties for their marketing purposes.

3. Data Storage

All your diary data is stored locally on your device in the app's secure sandbox. We do not have access to this data, and it is never transmitted to our servers or any external servers (except for optional cloud backup via Google Drive or iCloud, which you control).

4. Third-Party Services

Mongle Haru uses the following third-party services:

• Google AdMob: For displaying ads. AdMob collects and processes data as described in the Google Privacy Policy.
• Firebase Analytics / Crashlytics: For usage analytics and crash diagnostics. Data is processed under the Google Privacy Policy.
• Apple iCloud: For optional cloud backup (iOS only). Data is stored according to Apple's privacy practices.
• Google Drive: For optional cloud backup. Data is stored according to Google's privacy practices.

These services have their own privacy policies, and we encourage you to review them.

5. Children's Privacy

Mongle Haru is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have inadvertently collected such information, we will take steps to delete it. If you believe your child has provided us with personal information, please contact us at denru0907@gmail.com.

Our app complies with the Children's Online Privacy Protection Act (COPPA).

6. Your Rights

You have the following rights regarding your data:

• Access: You can view all your diary data within the app at any time.
• Correction: You can edit or update your diary entries at any time.
• Deletion: You can delete individual diary entries or all data within the app. If you have enabled cloud backup, you can also delete your data from Google Drive or iCloud.

California Residents: If you are a California resident, you have additional rights under the California Consumer Privacy Act (CCPA), including the right to know what personal information we collect, the right to delete your personal information, and the right to opt-out of the sale of personal information. We do not sell personal information.

To exercise your rights, please contact us at denru0907@gmail.com.

7. Data Security

We take reasonable measures to protect your data. Your diary data is stored locally on your device in the app's secure sandbox, protected by your device's operating system security features. If you enable cloud backup, your data is transmitted using industry-standard encryption (TLS) and stored securely by Google Drive or Apple iCloud.

Analytics and crash diagnostics do not include your diary content body, original photo files, or raw search keywords.

However, no method of electronic storage or transmission is 100% secure. While we strive to protect your data, we cannot guarantee absolute security.

8. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. We will notify you of any material changes at least 7 days in advance through an in-app notification. Your continued use of the app after the effective date of the updated policy constitutes your acceptance of the changes.
