Daikon 蘿蔔日記
隱私權政策 / Privacy Policy
摘要
本政策適用於 Daikon（蘿蔔日記）iOS App 與本支援網站。此 App 由個人開發者維護。蘿蔔日記不需要帳號，沒有開發者營運的伺服器，也不自行蒐集使用分析資料。你的經期記錄只屬於你，絕不會用於廣告。
資料存放
你登記的經期日期、週期與經期長度設定、提醒設定，以及由這些資料算出的預測，都保存在你的裝置上。若你的裝置已登入 iCloud，這些記錄會透過 Apple 的 iCloud（CloudKit）同步到你自己的私人資料庫，只有你的 Apple 帳號能存取；開發者無法讀取。
預測（下次經期、排卵日、受孕期）全部在裝置上計算，僅供參考，不是醫療建議，也不能作為避孕方法。
通知只在你於設定中開啟提醒後，才由裝置排程本機通知。你可隨時關閉提醒，或在 iOS 設定中關閉通知權限。
Apple 健康
「設定 → 同步至 Apple 健康」預設關閉。只有在你開啟並於系統畫面允許後，蘿蔔日記才會把你登記的經期日期以「月經」資料寫入 Apple 健康，之後隨你的修改更新。App 只會讀回自己寫入的這些資料，用來避免重複；不會讀取其他健康資料。從 Apple 健康取得的資料只在你的裝置上使用，不會傳到 iCloud、開發者、廣告服務或任何第三方，也不會用於廣告或行銷。關閉同步會停止寫入，已寫入的資料仍保留在健康 App；使用「設定 → 刪除所有記錄」時，蘿蔔日記寫入的資料也會一併刪除。你也可以在健康 App 或 iOS「設定 → 健康 → 資料取用權限與裝置」中隨時撤銷權限或刪除資料。
廣告
蘿蔔日記使用 Google AdMob 顯示廣告，且只請求非個人化廣告；App 不使用 Apple 廣告追蹤（ATT），不會詢問追蹤權限。你的經期與健康相關資料不會傳給廣告服務，也不會用於廣告或行銷。在適用地區，App 會在載入廣告前透過 Google User Messaging Platform（UMP）處理廣告同意。
即使是非個人化廣告，AdMob 仍可能處理 IP 位址、裝置與廣告互動資料，以及效能與診斷資料，用於廣告投放、頻率控制、防詐欺與衡量。詳見 Google 隱私權政策及 AdMob 資料使用說明。
購買
你可以在「設定 → 移除廣告」一次購買移除廣告，沒有訂閱。購買與還原由 Apple App Store 處理；蘿蔔日記不會取得你的付款資料。
資料刪除
在月曆點一下已登記的日期即可取消該天的記錄；在「設定 → 刪除所有記錄」可清除全部記錄，若已開啟 iCloud 同步，你的其他裝置與 iCloud 中的記錄也會一併刪除。只刪除 App 不會刪除 iCloud 中的記錄，你可在 iOS「設定 → [你的名字] → iCloud → 管理儲存空間」中刪除蘿蔔日記的資料。
本網站透過 GitHub Pages 提供，沒有開發者加裝的分析程式。GitHub 可能處理連線與技術紀錄，請參閱其 隱私權聲明。

Summary
This policy covers the Daikon (蘿蔔日記) iOS app and this support website. The app is maintained by an independent developer. Daikon requires no account, has no developer-operated server, and does not collect usage analytics itself. Your period logs belong to you and are never used for advertising.
Data stored
The period dates you log, your cycle and period length settings, reminder settings, and the predictions calculated from them are stored on your device. If your device is signed in to iCloud, these records sync through Apple’s iCloud (CloudKit) to your own private database, which only your Apple Account can access; the developer cannot read it.
Predictions (next period, ovulation, fertile window) are calculated entirely on your device. They are estimates, not medical advice, and must not be used as contraception.
Notifications are scheduled locally on your device only after you turn on a reminder in Settings. You can turn reminders off at any time or disable notifications in iOS Settings.
Apple Health
Settings → Sync to Apple Health is off by default. Only after you turn it on and allow access in the system sheet does Daikon write the period days you log to Apple Health as menstrual flow, and keep them in step with your edits. The app reads back only the samples it wrote itself, to avoid duplicates; it never reads other Health data. Data obtained from Apple Health is used only on your device and is never sent to iCloud, the developer, the ad service or any third party, and is never used for advertising or marketing. Turning sync off stops writing and leaves what is already in Health; Settings → Delete all logs also deletes the samples Daikon wrote. You can revoke access or delete the data at any time in the Health app or in iOS Settings → Health → Data Access & Devices.
Ads
Daikon uses Google AdMob to display ads and requests non-personalized ads only. The app does not use Apple App Tracking Transparency (ATT) and never asks to track you. Your period and health-related data is never sent to the ad service and is never used for advertising or marketing. Where required, the app uses Google’s User Messaging Platform (UMP) for advertising consent before loading ads.
Even for non-personalized ads, AdMob may process IP addresses, device and ad interaction data, and performance and diagnostic data for ad delivery, frequency capping, fraud prevention, and measurement. See Google’s Privacy Policy and AdMob’s data disclosure.
Purchases
You can make a one-time Remove ads purchase in Settings → Remove ads. There is no subscription. Apple App Store handles purchases and restoration; Daikon never receives your payment details.
Deleting your data
Tap a logged day in the calendar to remove it, or use Settings → Delete all logs to clear every record; with iCloud sync on, this also removes them from your other devices and iCloud. Deleting only the app does not delete records stored in iCloud; remove Daikon’s data in iOS Settings → [your name] → iCloud → Manage Storage.
This website uses GitHub Pages with no developer-added analytics scripts. GitHub may process connection and technical records; see its Privacy Statement.
