Privacy Policy
LOVE ORANGE TECHNOLOGY CO.,LTD ("we," "us," or "our") develops and operates the mobile application Perpetual Calendar (Chinese Almanac Calendar) (the "App"). We respect your privacy and are committed to handling your information in a transparent and responsible manner. This Privacy Policy explains how we collect, use, store, share, and protect information related to your use of the App.
By using the App, you acknowledge that you have read and understood this Privacy Policy. If you do not agree, please discontinue use of the App.
1. Scope
This Privacy Policy applies to:
- The iOS App Perpetual Calendar (Bundle ID:
com.juzipie.calendar); - The App's home screen widgets;
- Premium subscription and one-time purchase services offered through the App.
This Policy does not apply to third-party websites or services that you may access via links outside the App.
2. Information We Collect
2.1 Information You Provide or Generate in the App
The App primarily stores data locally on your device. The following data is stored on your device by default:
| Data Type | Purpose | Storage Location |
|---|---|---|
| App settings | Region, language, week start day, dark mode, almanac UI style, festival display preferences, etc. | On-device |
| Birthday / anniversary reminders | Reminder events and notification preferences you create | On-device |
| Period tracker configuration | Cycle length, period length, last start date, etc. (if you use this feature) | On-device |
| Premium purchase status | To verify access to premium features | Processed by Apple StoreKit; cached locally in the App |
We do not upload the above data to our own servers. Unless you actively use backup features or Apple system services, this data does not leave your device.
2.2 iCloud Backup & Sync (Premium Feature, Optional)
If you subscribe to premium and use Backup & Sync, the App will:
- Package the user data described above into JSON;
- Encrypt it locally using AES;
- Upload the encrypted backup file to your iCloud Drive container under your Apple ID (
iCloud.com.juzipie.calendar); - Store the encryption key in iCloud Keychain so you can decrypt and restore on other devices signed in with the same Apple ID.
In this process:
- Backup data is stored in your iCloud account, using Apple's infrastructure;
- We cannot access, read, or decrypt your iCloud backup content;
- Whether iCloud, iCloud Keychain, and storage space are available depends on your Apple account and system settings.
2.3 Local Export / Import Backup (Premium Feature, Optional)
You may export an encrypted backup file to your device or save it via the system share sheet to a location of your choice (e.g., Files app, third-party cloud storage). You are responsible for safeguarding exported files; we are not responsible for the security of external storage you choose.
2.4 Information Processed by Apple
The following is processed directly by Apple Inc. and is subject to Apple's Privacy Policy:
- App Store purchases, subscriptions, refunds, and restore purchases;
- Apple ID authentication;
- iCloud Drive and iCloud Keychain storage and sync.
Please refer to Apple's Privacy Policy for details.

No method of transmission or storage is 100% secure. You should safeguard your Apple ID credentials and use backup/restore only on trusted devices.
