P-Box (referred to as "we" or "us") takes your privacy seriously. This Privacy Policy explains in clear and transparent terms how we collect, use, store, and protect your personal information. Please read this policy carefully to understand how your information is handled.

1. Information We Collect

P-Box is a card-collection management app focused on local data storage. Our philosophy is your data belongs to you. The information we collect is extremely limited and used only to provide you with core services.

1.1 Content You Provide

All of the following data is stored only on your device (in the local Core Data database and the app's sandbox file system) and is never uploaded to our servers:

1.2 Permission Requests

To deliver the features above, we request the following device permissions only when needed, and each permission requires your explicit consent:

We request each permission only when you actively use the related feature, and you can revoke these permissions at any time in your iOS Settings.

1.3 In-App Purchase Data

When you purchase P-Box Pro, the entire purchase transaction is handled by Apple's App Store / StoreKit, including:

• Purchase receipts (managed by Apple; we use them only to verify whether you have purchased Pro)
• The "have I purchased Pro" flag (a single boolean value stored locally on your device)

We do not directly collect, store, or transmit your payment information (credit cards, bank accounts, etc.).

2. How We Store and Protect Your Data

2.1 Storage Methods

• Local Storage: All of your core data (cards, card boxes, images, templates, gacha configuration) is stored in your device's local Core Data database and sandbox file system.
• App Sandbox Isolation: System-level isolation protects your app data from other apps.
• Purchase Status: The "have I purchased Pro" status is stored locally on your device (UserDefaults). It is not tied to any account system.

⚠️ We currently do not implement any cloud data synchronization (iCloud, CloudKit, etc. are not enabled). All data is available only on the single device where it was created. Switching devices or uninstalling the app will cause data loss, so we strongly recommend using the in-app "Export Data" feature regularly to create local backups.

2.2 Data Security

We protect your data with the following measures:

• App Sandbox enabled for data isolation
• iOS system-provided encrypted storage (NSFileProtection)
• No collection, analysis, or sharing of your personal data with any third party
• No third-party analytics, advertising, social, or tracking SDKs are integrated

3. Third-Party Services

P-Box interacts only with official Apple services. All data transmission occurs within the Apple ecosystem:

We do not integrate any third-party analytics, advertising, social, or tracking SDKs.

4. Children's Privacy

P-Box does not knowingly collect personal information from children under 14. Our app contains no content directed at children and displays no third-party advertising. If you believe we have inadvertently collected information from a child, please contact us using the details below and we will delete the information promptly.

5. Your Rights

Under applicable privacy laws, you have the following rights regarding your data:

5.1 Right of Access

You can view all data you have created at any time within the app.

5.2 Right of Rectification

You can modify or edit your cards, card boxes, templates, and other data at any time within the app.

5.3 Right of Erasure

You can delete your data in the following ways:

• Single-item deletion: Delete individual cards, card boxes, or templates in the app.
• Reassignment: Use the "Move to Another Card Box" feature to change card associations.
• Image cache cleanup: In "Settings → Data Management → Clear Cache" you can remove cached image copies (this does not delete your original data).
• Complete deletion: Uninstall the app to remove all data on the device (a device-level operation).

📌 Because data is stored entirely locally, there is no "one-tap delete all data" button inside the app. To delete everything, uninstall the app, or clear the app's data from the system Settings.

5.4 Right of Data Export

We provide a complete data export feature (Settings → Data Management → Export Data) that exports all of your data as a ZIP backup file (including images and JSON data).

5.5 Right of Data Import

We provide a data import feature (Settings → Data Management → Import Data) for restoring a previous backup or migrating data between devices.

5.6 Right to Withdraw Consent

You can disable camera, photo library, or other permissions at any time in iOS "Settings → Privacy". Disabling a permission will make the related feature unavailable, but it will not affect your use of the app's other features.

6. Changes to This Privacy Policy

We may revise this policy as our product features evolve or as laws and regulations change. Material changes will be communicated via in-app notification or in the App Store update notes. Continued use of P-Box after such changes indicates your acceptance of the revised policy.

7. Contact Us

If you have any questions, comments, or complaints about this Privacy Policy, please contact us through the following channels:

• In-app feedback: Settings → About → Contact Us (in-app submission form)
• Privacy-specific email: jenniawang@outlook.com (for privacy and legal matters only)

We will respond to your feedback within 7 business days of receipt.

8. Governing Law

This Privacy Policy is governed by, and construed in accordance with, the laws of the People's Republic of China. In the event of any conflict between any provision of this policy and applicable laws or regulations, the laws and regulations shall prevail.
