1.4 图鉴内容与图片
- 您创建的图鉴书、图鉴条目与图片通常存储在您的设备本地
- 当您发起 AI 识别/生成时，您选择的图片及必要的提示信息会发送至第三方 AI 服务提供方处理（见“第三方信息共享”与“第三方信息共享清单”）
二、我们如何使用信息
- 提供账号注册/登录、游客会话、Token 余额与计费服务。

三、我们如何共享信息
3.1 第三方 AI 服务（Qwen / DashScope）
当您使用 AI 识别/生成功能时，图片与必要的提示信息会通过网络发送至第三方 AI 服务提供方处理并返回结果。本应用仅使用 Qwen AI，不使用其他 AI（例如 DeepSeek）。
3.2 Apple（App Store / StoreKit）
当您进行应用内购买时，Apple 作为支付与交易处理方会处理相关信息。我们无法访问您的 Apple 账户密码等敏感信息。

Effective Date: February 18, 2026
We take your privacy seriously. This Privacy Policy explains how Compendium collects, uses, stores, and shares information. If you do not agree with any part of this Policy, please stop using the App.
1. Information We Process
1.1 Account Information (Optional)
If you register/log in, we process:
- Email
- Password (for authentication)
- Optional nickname
1.2 Session and Billing Information
To provide token balance and billing:
- Authentication token (stored in iOS Keychain)
- Wallet identifier and token balance
- A guest installation identifier (randomly generated; not a hardware serial number)
1.3 Purchase and Top-up Information (Optional)
When you top up tokens via in-app purchases:
- Apple processes payment and transaction information
- The App submits necessary transaction data to our server (e.g., transactionId, productId, and JWS/receipt data where applicable) for crediting and verification
1.4 Compendium Content and Images
- Your books, entries, and images are typically stored locally on your device
- When you request AI generation, the selected image and necessary prompt information are sent to the third-party AI provider for processing (see "Third-Party Sharing" and the Third-Party Information Sharing List)
2. How We Use Information
- To provide guest sessions, account services, token balance, and billing.
- To process in-app purchase top-ups and transaction verification.
- To maintain service security and prevent abuse.
3. How We Share Information
3.1 Third-Party AI Service (Qwen / DashScope)
When you use AI features, your image and necessary prompt information are transmitted to the third-party AI provider for processing and returned to you. The App only uses Qwen AI and does not use other AI providers (e.g., DeepSeek).
3.2 Apple (App Store / StoreKit)
For in-app purchases, Apple processes relevant information as the payment and transaction provider. We do not have access to sensitive Apple account credentials.
3.3 Other Third Parties
As of the effective date, the App does not integrate third-party advertising/analytics SDKs. If this changes, we will update this Policy and obtain consent where required.
4. Data Storage and Security
- Local storage: Compendium content and images are typically stored in the app sandbox on your device. Sensitive credentials such as authentication tokens are stored in iOS Keychain.
- Transport security: We use encrypted transport such as HTTPS between the App, our servers, and third-party services.
- Data minimization: We do not automatically upload your entire compendium library to our servers. Data is exchanged only when needed for account/billing/top-up features or when you request AI processing.
5. Deletion and Your Rights
- You can delete books/entries within the App. Uninstalling the App will remove locally stored data (subject to iOS behavior).
- To close your account or delete server-side account information, you can complete self-service deletion at https://mtheory.cn/delete-account/; if needed, you may still contact us via in-app support or email.
6. Children's Privacy
The App is not intended for children under 13. If we learn that we processed children's personal information, we will delete it as soon as reasonably possible.
7. Changes to This Policy
We may update this Policy from time to time. Material changes will be posted in the App or on the support site. Continued use indicates acceptance of the updated Policy.
