食熵 FoodEntropy · 最後更新 Last updated: 2026-07-23

中文

一句話總結：食熵不蒐集、不上傳、不分享你的個人資料。你的食材紀錄與照片都存在你的裝置上；若你自行開啟 iCloud 同步，資料會備份到你自己的私有 iCloud（由 Apple 保管），開發者無法存取。本 App 透過 Google AdMob 顯示非個人化廣告（不追蹤、不跳 ATT），詳見下方說明。

我們蒐集哪些資料

食熵沒有帳號系統、沒有自建伺服器、沒有第三方分析工具。你在 App 內輸入的內容僅供 App 功能使用：

食材資料（名稱、購買日期、到期日期）：儲存於你的裝置本機。
食材照片（相機拍攝或相簿選取）：壓縮後儲存於本機，僅用於在清單上辨識食材。
通知：到期提醒為 iOS 本機通知（Local Notification），不會傳送任何資料到外部。

iCloud 同步（選用）

iCloud 同步預設關閉。若你主動開啟，App 會透過 Apple 的 CloudKit 將你的食材資料備份到你自己的私有 iCloud 帳戶。此資料由 Apple 依其條款保管，開發者無法存取。你可隨時在設定中關閉。

廣告（Google AdMob）

食熵為免費 App，透過 Google AdMob 顯示廣告維持營運。我們投放非個人化廣告，不請求追蹤許可（ATT）、不使用廣告識別碼（IDFA）進行跨 App 追蹤。

即使是非個人化廣告，Google 仍可能為了投放廣告、頻率控制與防止詐騙，處理有限的裝置與使用資訊（例如 IP 位址、粗略的裝置資訊）。這部分由 Google 依其條款處理，開發者無法存取個別使用者資料。詳見 Google 如何使用資料。

我們不做的事

不要求註冊或登入帳號。
不將你的資料傳送到開發者的伺服器（我們沒有伺服器）。
不使用第三方分析 SDK（無 Firebase / 無第三方 Analytics）。
不進行跨 App 廣告追蹤（不跳 ATT、不用 IDFA 做個人化廣告）。
不販售你的個人資料。

權限用途

相機 / 相簿：僅用於為食材新增照片。
通知：僅用於到期提醒；可於系統設定隨時關閉。

兒童

本 App 適合一般使用者，不刻意蒐集任何年齡層的個人資料。

政策變更

本 App 目前透過 Google AdMob 顯示非個人化廣告。若未來調整資料使用方式（例如改投個人化廣告），本政策會隨之更新，並於此頁標註更新日期。

English

In one sentence: FoodEntropy does not collect, upload, or share your personal data. Your food records and photos stay on your device; if you turn on iCloud sync yourself, they are backed up to your own private iCloud (managed by Apple), which the developer cannot access. The app shows non-personalized ads via Google AdMob (no tracking, no ATT prompt) — see below.

What we collect

FoodEntropy has no account system, no server of our own, and no third-party analytics. Anything you enter is used solely for the app's features:

Food data (name, purchase date, expiry date): stored locally on your device.
Food photos (from camera or photo library): compressed and stored locally, used only to identify items in your list.
Notifications: expiry reminders are local iOS notifications; no data is sent anywhere.

iCloud sync (optional)

iCloud sync is off by default. If you turn it on, the app uses Apple's CloudKit to back up your food data to your own private iCloud account. That data is held by Apple under its terms and is not accessible to the developer. You can turn it off anytime in Settings.

Ads (Google AdMob)

FoodEntropy is a free app supported by ads shown through Google AdMob. We serve non-personalized ads and do not request tracking permission (ATT) or use the advertising identifier (IDFA) for cross-app tracking.

Even for non-personalized ads, Google may process limited device and usage information (such as IP address and coarse device data) to serve ads, cap frequency, and prevent fraud. This is handled by Google under its own terms; the developer cannot access individual user data. See How Google uses data.

What we don't do

No sign-up or login required.
No sending your data to any developer-run server (we don't have one).
No third-party analytics SDKs (no Firebase, no third-party analytics).
No cross-app ad tracking (no ATT prompt, no IDFA for personalized ads).
We do not sell your personal data.

Permissions

Camera / Photos: only to add photos to food items.
Notifications: only for expiry reminders; can be turned off anytime in system settings.

Children

This app is for a general audience and does not knowingly collect personal data from anyone.

Changes to this policy

The app currently shows non-personalized ads via Google AdMob. If we change how data is used (for example, switching to personalized ads), this policy will be updated and the date above revised.
