隱私政策

袖裡乾坤·梅花易占 · 生效日期：2026年8月14日

梅花易占（袖裡乾坤系列，以下稱「本應用程式」）由開發者 freecelestial 提供。本政策說明我們如何收集、使用及保護您的個人資料。

一、我們收集的資料

• 帳號資訊：透過第三方登入（Google、LINE）取得您的顯示名稱、電子郵件地址及個人頭像網址。您也可選擇以匿名方式使用，此時我們不會取得任何可識別身分的資訊。
• 卜卦記錄：您送出的卜卦資料，包含您自行填寫的事由名稱與觸機描述、起卦方法與變數值或擲錢爻值、選填的生肖、起卦日期時辰、建立時間，以及您事後標記的應驗結果與註記（卦象由 App 依這些輸入即時重算，不另儲存）。
• 廣告識別碼：為顯示廣告，Google AdMob 會存取您裝置的廣告識別碼（Advertising ID）。詳見第三節。
• 應用程式偏好：語言與顯示設定儲存於裝置本機，不上傳。

本應用程式不使用相機、麥克風、定位或裝置感測器，亦不讀取您的通訊錄。

二、資料用途

• 驗證身份並維護您的帳號
• 跨裝置同步儲存您的卜卦記錄
• 提升應用程式功能與使用體驗
• 顯示廣告並衡量廣告成效（僅涉及廣告識別碼，見第三節）

我們不會將您的帳號資訊或卜卦記錄出售、出租或提供給廣告商或其他第三方。廣告識別碼的處理方式另見第三節。

三、廣告與廣告識別碼

本應用程式免費提供，營運成本由廣告收入支應。我們透過 Google AdMob 顯示橫幅廣告、插頁廣告，以及由您自行選擇觀看、用於兌換記錄配額的獎勵式影片廣告。

為投放廣告並衡量成效，Google AdMob 會存取您裝置的廣告識別碼，並可能與其廣告合作夥伴分享。該識別碼不包含您的姓名或電子郵件地址；您可隨時於 Android 系統的「設定 → Google → 廣告」重設或刪除它。

若您位於歐洲經濟區、英國或瑞士，本應用程式會在首次啟動時顯示同意聲明，供您選擇是否接受個人化廣告。您可隨時於應用程式「帳號」頁面的「廣告與隱私設定」重新開啟該聲明，變更或撤回您的選擇。

關於 Google 如何使用這些資料，請參閱 Google 合作夥伴網站與應用程式資料使用政策。

四、LINE 登入

當您選擇以 LINE 登入時，我們僅取得您在 LINE 的顯示名稱、頭像與（若您授權）電子郵件地址，用於建立與識別您的帳號。本應用程式不會代您發送任何 LINE 訊息，也不會存取您的好友清單或聊天內容。

五、第三方服務

本應用程式使用 Google Firebase（Auth、Firestore、Cloud Functions、Remote Config、Crashlytics、Hosting）處理資料，並使用 Google AdMob 顯示廣告，兩者均受 Google 隱私政策約束。Crashlytics 會在應用程式異常時收集不含個人身分的當機診斷資訊。除第三節所述的廣告識別碼外，我們不會將您的資料提供給其他第三方。

六、資料保留與刪除

您的資料將保留至您主動刪除帳號為止。可於應用程式「帳號」頁面選擇「刪除帳號」，永久刪除所有個人資料與卜卦記錄。

七、聯絡我們

Privacy Policy

Meihua I-Ching (Xiuli Qiankun) · Effective Date: August 14, 2026

Meihua I-Ching (the "App", part of the Xiuli Qiankun series) is developed by freecelestial. This policy explains how we collect, use, and protect your personal data.

1. Data We Collect

• Account Information: When you sign in via a third-party provider (Google, LINE), we receive your display name, email address, and profile picture URL. You may also use the App anonymously, in which case we collect no personally identifying information.
• Divination Records: Readings you submit, including the subject title and trigger description you write yourself, the casting method and variable value or coin-toss line values, optional zodiac sign, casting date and hour, creation time, and any outcome status and notes you add later. Hexagram results are recomputed from these inputs on demand and are not stored separately.
• Advertising ID: Google AdMob accesses your device's Advertising ID in order to serve ads. See Section 3.
• App Preferences: Language and display settings are stored locally on your device and are not transmitted.

The App does not use the camera, microphone, location, or device sensors, and does not read your contacts.

2. How We Use Your Data

• To authenticate you and maintain your account
• To store and sync your divination records across devices
• To improve app functionality and user experience
• To serve ads and measure ad performance (Advertising ID only — see Section 3)

We do not sell, rent, or share your account information or divination records with advertisers or any other third party. Handling of the Advertising ID is described in Section 3.

3. Advertising and the Advertising ID

The App is free to use and its operating costs are covered by advertising revenue. We use Google AdMob to display banner ads, interstitial ads, and rewarded video ads that you may optionally watch to earn additional record slots.

To serve ads and measure their performance, Google AdMob accesses your device's Advertising ID and may share it with its advertising partners. This identifier does not contain your name or email address, and you can reset or delete it at any time under Settings → Google → Ads on your Android device.

If you are located in the European Economic Area, the United Kingdom, or Switzerland, the App presents a consent notice on first launch so you can choose whether to accept personalised advertising. You may reopen that notice at any time via Account → Ad & Privacy Settings in the App to change or withdraw your choice.

For details on how Google uses this data, see Google's policy on how it uses data from sites and apps that use its services.

4. LINE Login

When you choose LINE Login, we receive only your LINE display name, profile picture, and (if you grant permission) email address, used to create and identify your account. The App never sends LINE messages on your behalf and does not access your friend list or chat history.

5. Third-Party Services

The App uses Google Firebase (Auth, Firestore, Cloud Functions, Remote Config, Crashlytics, Hosting) for data processing and Google AdMob to display ads; both are subject to Google's Privacy Policy. Crashlytics collects non-identifying crash diagnostics when the App encounters an error. Apart from the Advertising ID described in Section 3, we do not share your data with other third parties.

6. Data Retention & Deletion

Your data is retained until you delete your account. You may permanently delete all personal data and divination records via Account → Delete Account in the App.
