「i 刷」（iBrush）重視您的隱私。本政策說明我們如何處理資料。
我們收集或使用的資料
- 機器學習偵測（iOS Core ML）：i 刷透過 iOS Core ML 機器學習訓練模型在設備本地偵測刷牙。i 刷不會在未經使用者同意下上傳任何刷牙資料到網路上。如果使用者同意協助改善偵測模型，會將匿名刷牙資料傳往 Firebase Storage 做模型訓練用，不做其他用途，且會在 180 天內刪除資料。
- iCloud 私有資料庫（CloudKit Private DB）：您的刷牙記錄資料（孩子暱稱、刷牙紀錄與獎勵設定等）會以結構化格式儲存在您 Apple ID 名下的 iCloud 私有資料庫。只有您本人可存取，開發者無法檢視。
- iCloud 共享（CloudKit Shared DB）：「i 刷」支援 iCloud 共享功能，讓您與他人共享刷牙記錄。共享資料同樣以結構化格式儲存，僅限共享發起者與受邀者能檢視，開發者無法存取。
- 推播通知權限：用於資料同步事件通知。
- 廣告（Google Mobile Ads / AdMob）：為提供免費服務，我們展示廣告。廣告供應商可能蒐集裝置資訊（如 IDFA、粗略位置、裝置型號、IP 位址）以投遞、衡量與防止不正常流量。您可在 iOS【設定 ▸ 隱私權與安全性 ▸ 追蹤】管理追蹤許可，或重設廣告識別碼。
我們不會
- 建立帳號或要求登入。
- 在未經同意下上傳刷牙資料；刷牙偵測完全在設備本地進行。
- 將您的個人內容上傳到開發者自有伺服器；資料只會存在於您的 iCloud 私有資料庫或您參與的共享資料庫中。
- 讀取您未主動選取的照片；僅在您挑選頭像或貼紙圖片時存取，並只做圓形裁切與壓縮後儲存。
資料保留與安全
- 您可隨時刪除 App；資料仍存於您的 iCloud，直到您於 iCloud 介面或於重新安裝後在 App 內刪除。
- CloudKit 之傳輸與儲存安全由 Apple 提供；我們不會另行上傳到第三方伺服器。
- 若您選擇分享匿名刷牙資料以改善模型，這些資料會在 Firebase Storage 保留最多 180 天後自動刪除。
第三方服務
- Apple iCloud / CloudKit（私有儲存與同步）
- Apple Core ML（本地機器學習偵測）
- Firebase Storage（僅在使用者同意時，用於匿名模型訓練資料）
- Google Mobile Ads SDK（廣告投放與衡量）
兒童隱私
本 App 供親子共同使用；我們不要求兒童輸入個人身分資訊。請家長妥善管理裝置與 iCloud 帳號。

iBrush ("the App") values your privacy. This policy explains how your data is handled.
Data we collect/use
- Machine Learning Detection (iOS Core ML): iBrush uses iOS Core ML machine learning models to detect brushing locally on your device. iBrush does not upload any brushing data to the internet without user consent. If you agree to help improve the detection model, anonymous brushing data will be uploaded to Firebase Storage for model training purposes only, and will be automatically deleted within 180 days.
- iCloud CloudKit Private DB: Your brushing record data (child nicknames, brushing records, rewards) is stored in a structured format in your iCloud Private Database. Only you can access it; the developer cannot view it.
- iCloud CloudKit Shared DB: iBrush supports iCloud sharing, allowing you to share brushing records with others. Shared data is also stored in a structured format. Only the share creator and invitees can view it; the developer cannot access it.
- Push Notifications: Used for data sync notifications.
- Ads (Google Mobile Ads / AdMob): To keep the App free, we serve ads. The provider may collect device info (IDFA, coarse location, model, IP) for delivery, measurement, and fraud prevention. You can manage App Tracking Transparency in iOS settings or reset the advertising identifier.
We do not
- Create accounts or require sign-in.
- Upload brushing data without consent; brushing detection is performed entirely on-device.
- Upload your personal content to developer-run servers; your data stays in your iCloud Private Database or shared databases you participate in.
- Access photos you did not explicitly pick; selected images are cropped into a circle and compressed for storage.
Retention & Security
- You may delete the App anytime; data remains in iCloud until you remove it via iCloud or within the App after reinstall.
- Transport and at-rest security are provided by Apple CloudKit; we do not upload to other third-party servers.
- If you choose to share anonymous brushing data to improve the model, this data will be automatically deleted from Firebase Storage within 180 days.
Third-Party Services
- Apple iCloud / CloudKit (private storage & sync)
- Apple Core ML (on-device machine learning detection)
- Firebase Storage (only with user consent, for anonymous model training data)
- Google Mobile Ads SDK (ads & measurement)
Children's Privacy
The App is intended for family use. We do not ask children to submit personal identifying information. Parents should manage the device and iCloud account appropriately.
