CalorieRecycle 隱私權政策

生效日期：2026 年 10 月 3 日（先前版本：2026 年 4 月 25 日）

1. 總覽

CalorieRecycle（以下簡稱「本 App」）由 Anderson Tsai 開發，並尊重您的隱私。本政策說明本 App 收集哪些資料、如何使用、如何保護，以及您的權利。

2. 我們收集哪些資料

2-1 Apple HealthKit 資料

本 App 會在您授權後，讀取並寫入 Apple 健康 App 中的以下資料類型：

  • 活動能量 / Active Energy Burned
  • 基礎代謝能量 / Basal Energy Burned
  • 步數 / Step Count
  • 體重 / Body Weight
  • 身高 / Height
  • 出生日期（用於計算年齡）
  • 性別（用於計算 BMR）
  • 飲食熱量及各大營養素（碳水化合物、蛋白質、脂肪等）
  • 心率、靜止心率、HRV、血氧、體脂等（可選顯示）

本 App 將飲食記錄寫回健康 App，讓其他健康應用可同步使用。您的 HealthKit 原始資料僅儲存於您的裝置本地，不會上傳至任何伺服器。唯一例外：若您主動加入「好友群組」，App 會上傳由這些資料彙總出的數字（見 2-5），而非原始樣本。

2-2 相機

當您使用條碼掃描功能時，本 App 會請求相機權限以擷取食品條碼圖像，並即時解析後丟棄，不留存任何影像或視訊。

2-3 本機儲存資料

以下資料儲存於您裝置的 UserDefaults / 本機資料庫，不會傳送至外部：

  • 飲食日記（食物名稱、份量、熱量、時間）
  • 個人設定（語言、體重單位、熱量目標、活動量）
  • 健康快取（加速啟動用，定期從 HealthKit 更新）

2-4 外部 API

本 App 使用以下外部服務查詢食品營養資料，查詢關鍵字（食品名稱或條碼）會傳送至該服務：

  • USDA FoodData Central API（美國農業部食品資料庫）
  • Open Food Facts API（開放食品資料庫）

以上服務均為公開資料庫，不包含您的個人識別資訊。請參閱各服務的隱私政策以了解其資料處理方式。

2-5 好友群組（選用功能）

只有在您主動建立或加入好友群組後，本 App 才會把「當日彙總數字」寫入 Apple iCloud CloudKit 的公開資料庫，讓同群組成員看到。內容包含：

  • 暱稱（取自您的 Game Center 顯示名稱）與 iCloud 使用者識別碼
  • 當日攝取熱量、消耗熱量、熱量目標、步數、飲水量、運動分鐘數與次數、連續達標週數
  • （依您選擇的分享等級）蛋白質／碳水／脂肪克數與每週摘要文字

我們不會上傳逐筆飲食記錄、食物名稱、體重，也不會上傳心率、HRV、血氧、最大攝氧量或個別運動紀錄等 HealthKit 原始樣本。您可隨時在 App 內退出群組，您在該群組的紀錄會一併刪除。這些資料存放於 Apple CloudKit，由 Apple 依其隱私政策處理；開發者不自建伺服器。

2-6 社群食物資料庫（選用功能）

若您選擇把自訂食物分享給社群，該食物的名稱、品牌、營養成分、條碼與您的 iCloud 使用者識別碼（用來去除重複與管理檢舉）會寫入 CloudKit 公開資料庫，其他使用者可以搜尋到。其中營養成分也可能被貢獻回 Open Food Facts（以匿名帳號送出，不含您的個人資料）。未分享的自訂食物只存在您的裝置上。

3. 我們不收集的資料

  • 本 App 不收集任何個人識別資訊（姓名、電子郵件、電話等）
  • 本 App 不要求建立帳號；僅在使用好友群組時，會讀取您的 Game Center 暱稱與 iCloud 識別碼
  • 本 App 不使用廣告追蹤或第三方分析 SDK
  • 本 App 沒有開發者自建的伺服器，不會將您的健康原始資料傳送給開發者

4. 資料使用目的

所有資料均僅用於以下目的：

5. HealthKit 特別聲明

依據 Apple 開發者指南，本 App 特別聲明：

6. 資料安全

本機資料儲存於您的裝置，受 iOS 系統層級的沙盒保護。除非您使用好友群組或社群食物（見 2-5、2-6），資料不會離開裝置，本 App 也不做雲端備份。刪除本 App 會移除所有本機資料；已上傳到 CloudKit 的好友群組紀錄，請先於 App 內退出群組，或來信請我們協助刪除。

7. 兒童隱私

本 App 不針對 13 歲以下兒童設計，亦不有意收集兒童個人資料。

8. 您的權利

您可隨時透過 iOS「設定 → 隱私權 → 健康」撤銷 HealthKit 存取權限。撤銷後，本 App 將無法讀取或寫入健康資料。您也可以在 App 內退出好友群組以刪除上傳的彙總紀錄，或直接刪除本 App 以移除所有本機資料。

9. 政策更新

本政策如有重大變更，將透過 App Store 版本更新通知。繼續使用本 App 即表示您同意更新後的政策。

Privacy Policy

CalorieRecycle Privacy Policy

Effective Date: October 3, 2026 (previous version: April 25, 2026)

1. Overview

CalorieRecycle (the "App") is developed by Anderson Tsai. We respect your privacy. This policy describes what data the App collects, how it is used, how it is protected, and your rights.

2. What Data We Collect

2-1 Apple HealthKit Data

With your permission, the App reads and writes the following data types in Apple Health:

  • Active Energy Burned
  • Basal Energy Burned
  • Step Count
  • Body Weight
  • Height
  • Date of Birth (for age calculation)
  • Biological Sex (for BMR calculation)
  • Dietary Energy & Macronutrients (carbs, protein, fat, etc.)
  • Heart Rate, Resting HR, HRV, Blood Oxygen, Body Fat, etc. (optional display)

The App writes food log entries back to Apple Health so other apps can sync. Your raw HealthKit data is stored locally on your device and is never uploaded to any server. The only exception: if you choose to join a Friend Group, the App uploads numbers summarized from that data (see 2-5), never the raw samples.

2-2 Camera

When you use the barcode scanner, the App requests camera access to capture barcodes. Images are decoded in real time and immediately discarded — no photos or videos are stored.

2-3 Local Storage

The following data is stored locally in UserDefaults / on-device storage and never sent off-device:

  • Food diary (food name, serving size, calories, timestamp)
  • User preferences (language, weight unit, calorie goal, activity level)
  • Health cache (for fast startup; periodically refreshed from HealthKit)

2-4 External APIs

The App queries these external services for food nutrition data; the search keyword (food name or barcode) is sent to each service:

  • USDA FoodData Central API
  • Open Food Facts API

These are public databases; your search does not include any personally identifiable information. See each service's privacy policy for their data practices.

2-5 Friend Groups (optional)

Only after you create or join a Friend Group does the App write daily summary numbers to the Apple iCloud CloudKit public database so that members of the same group can see them. This includes:

  • A nickname (from your Game Center display name) and your iCloud user identifier
  • Daily calories in, calories out, calorie goal, step count, water intake, workout minutes and count, and weekly-goal streak
  • (Depending on the sharing level you choose) grams of protein / carbs / fat and a weekly summary text

We do not upload itemized food logs, food names, or body weight, nor HealthKit raw samples such as heart rate, HRV, blood oxygen, VO2 max, or individual workouts. You can leave a group at any time inside the App, which deletes your records for that group. This data is stored in Apple CloudKit and handled under Apple's privacy policy; the developer runs no servers of their own.

2-6 Community Food Database (optional)

If you choose to share a custom food with the community, its name, brand, nutrition values, barcode, and your iCloud user identifier (used to remove duplicates and manage reports) are written to the CloudKit public database where other users can find it. The nutrition values may also be contributed to Open Food Facts using an anonymous account, with no personal data about you. Custom foods you do not share stay on your device only.

3. What We Do NOT Collect

  • The App does not collect any personally identifiable information (name, email, phone, etc.)
  • The App does not ask you to create an account; only when you use Friend Groups does it read your Game Center nickname and iCloud identifier
  • The App does not use ad-tracking or third-party analytics SDKs
  • The developer runs no servers of their own and does not receive your raw health data

4. How We Use Your Data

All data is used solely for:

5. HealthKit Disclosure

As required by Apple's developer guidelines, the App explicitly discloses:

6. Data Security

Local data is stored on your device, protected by iOS system-level sandboxing. Unless you use Friend Groups or the community food database (see 2-5, 2-6), data never leaves your device and the App makes no cloud backup. Deleting the App removes all local data; for summary records already uploaded to CloudKit, please leave the group inside the App first, or email us and we will help delete them.

7. Children's Privacy

The App is not directed at children under 13 and does not knowingly collect personal data from children under 13.

8. Your Rights

You may revoke HealthKit access at any time via iOS Settings → Privacy & Security → Health. After revoking, the App will no longer be able to read or write health data. You may also leave a Friend Group inside the App to delete your uploaded summary records, or delete the App to remove all local data.

9. Policy Updates

If we make material changes to this policy, we will notify you through an App Store update. Continued use of the App after updates constitutes acceptance of the revised policy.
