This Privacy Policy explains how we handle your data when you use "Zen Mood". We adhere to the principles of "minimization, necessity, and transparency".

Important: When you tap "Generate Sign", the text you input is sent to a third-party AI service for processing. To protect your privacy, please do not input sensitive personal information.

1. Who We Are

• Developer/Operator: Individual Developer (Beijing, China)
• Contact Email: [email protected]

2. What Data We Process

2.1 Data Generated/Stored Within the App (Primarily Local)

• Diary/Mood Text: The content you input.
• Generation Results: Titles, poems, scores, stamp characters, colors, etc.
• App Settings: E.g., daily reminder status, reminder time, usage statistics, subscription status (for local display).

2.2 Purchase & Subscription Data

The App uses Apple StoreKit for subscription services. Purchases, billing, refunds, and renewals are handled by Apple. We read and verify subscription status on your device (e.g., whether a subscription is valid) to unlock premium features.

2.3 Notification Data

When you enable "Daily Reminder", the App creates a local calendar notification schedule on your device. This process does not upload your diary content.

3. Data Storage & Retention

• Local Storage: Diaries and generation records are saved by default in your device's local database (SwiftData).
• System Backup: If you enable iOS device backups (e.g., iCloud Backup), local App data may be backed up and restored with the system. Backup contents and restoration mechanisms are determined by Apple and your system settings.
• Retention: Local data remains on your device unless you actively delete it or uninstall the App.

The current version does not provide a server-side account system or "cross-device sync" (subject to actual features).
