统计与崩溃诊断
统计与崩溃诊断默认开启：Google Firebase Analytics 处理安装标识、设备和系统信息、粗略地区及产品使用和购买结果；Crashlytics 处理安装标识、设备信息、崩溃堆栈和固定分类错误码。不使用 IDFA、IDFV 或自定义账号标识，不将题盘、答案、照片、iCloud 账号、交易凭证或输入文本发送至这些服务。本 App 无广告，不用于跨 App 广告追踪。已发送数据按 Google 服务的保留政策处理。Google 处理说明：https://firebase.google.com/support/privacy 。
六、权限使用
本应用可能使用网络访问 Apple 服务（如 Game Center、StoreKit、iCloud 同步和 App Store 跳转），并使用本地存储保存游戏数据。当你主动选择“拍摄题目”时，本应用会打开 iOS 系统单张相机并且只接收你确认的一张照片；你也可以通过系统 PhotosPicker 单次选择一张图片。Vision、Core Image 与 C++ 数独校验器仅在本机内存中处理原图、中间图像和识别结果。本应用不会上传或持久化原图与识别结果，不会将它们保存到相册或 iCloud，并会在识别或解题流程结束时释放。本应用默认向 Google Firebase 发送上述统计与诊断数据。
七、未成年人隐私

Sudoku Pro Privacy Policy
App name: Sudoku Pro
Developer: ChnXing
Last updated: September 13, 2026
Effective date: September 13, 2026
Sudoku Pro values your privacy. The app is a Sudoku game. The app has no advertising SDKs or account system of its own. Starting with 1.0.5, Google Firebase analytics and crash diagnostics are enabled by default.
1. Whether We Collect Personal Data
The app does not sell personal data. Analytics and diagnostics services process installation identifiers and the usage and diagnostic information described below. Your game progress, settings, records, favorites, mistakes, check-ins, and cached membership status are primarily stored on your device.
2. Local Storage and iCloud
The app uses local storage to save game progress, settings, records, favorites, mistakes, check-ins, and cached membership state. If you are signed in to iCloud, app data may sync across your own devices through Apple iCloud / CloudKit. This sync is provided and managed by Apple. We cannot access the contents of your iCloud.
3. Game Center and Leaderboards
When you use Game Center leaderboards, Apple Game Center may process your Game Center account, nickname, avatar, leaderboard scores, and related information. Game Center is provided by Apple, and Apple handles that data under its own privacy policy. The app only uses Apple's official APIs to show or submit leaderboard scores.
4. In-App Purchases and Subscriptions
Membership subscriptions and lifetime purchases are processed through Apple App Store / StoreKit. Payment, billing, receipts, and Apple ID related information are handled by Apple. We do not access or store your bank card, payment account, or complete billing information. The app only stores locally verified membership entitlement state from Apple so it can unlock Pro features.
5. No Ads and No Third-Party Tracking
The app contains no ads, does not integrate third-party advertising SDKs, does not use App Tracking Transparency for cross-app or cross-website tracking, and does not use your data for personalized advertising.
Analytics and crash diagnostics
Analytics and crash diagnostics are enabled by default. Google Firebase Analytics processes installation identifiers, device and system information, approximate region, product usage and purchase outcomes. Crashlytics processes installation identifiers, device information, crash stacks and categorized error codes. We do not use IDFA, IDFV or custom account identifiers or send puzzle boards, answers, photos, iCloud accounts, transaction receipts or entered text to these services. The app has no ads and does not use this data for cross-app advertising tracking. Sent data follows Google’s service retention policies. Google’s processing details: https://firebase.google.com/support/privacy .
6. Permissions and System Services
The app may use network access to connect to Apple services such as Game Center, StoreKit, iCloud sync, and App Store links. It also uses local storage for game data. When you choose Photograph Puzzle, the app opens the iOS system camera for one photo; you may also select one image through the system PhotosPicker. Vision, Core Image, and the C++ Sudoku validator process the original image, intermediate images, and recognition results only in memory on this device. The app does not upload or persist the original image or recognition results, does not save them to Photos or iCloud, and releases them when the recognition or solve flow ends. The app sends the analytics and diagnostic data described above to Google Firebase by default.
7. Children's Privacy
The app does not knowingly collect personal information from children under 13. If you believe that we have unintentionally processed children's personal information, please contact us using the email below.
8. Your Choices and Rights
You can delete the app from your device to remove locally stored data. If iCloud sync is enabled, you can manage or delete related iCloud data in iOS system settings. Game Center, Apple ID, and purchase records should be managed through your Apple account or system settings.
9. Policy Updates
If a future version changes how data is processed or adds related capabilities, we will update this policy and, where required, ask for your consent in the app.
