Last updated: 2026-08-28最後更新：2026-08-28

本 App（以下稱「本服務」）重視你的隱私。本政策說明我們蒐集哪些資料、如何使用，以及你的權利。

一、我們蒐集的資料

免費內容不需登入、不蒐集任何個人資料。

付費解鎖採「匿名購買」，不需登入或註冊帳號。當你完成購買，我們會在伺服器儲存：

• 交易識別碼：由 App Store 提供的交易識別碼。
• 解鎖狀態：用來確認並維持你的購買權益（包含日後退款時撤銷權益）。

我們並會發給你的裝置一組匿名購買憑證，安全存放於裝置本機。此過程不蒐集你的姓名、電子郵件或 Apple 帳號身分。本 App 不提供、也不需要登入或註冊帳號。

我們不會蒐集：你的信用卡或付款資訊（付款完全由 Apple 處理，我們永遠看不到你的付款細節）、你的通訊錄、位置、相機或相簿。

二、只存在你裝置上的資料

以下資料只儲存在你的裝置本機，不會上傳到我們的伺服器：

• 閱讀進度與已讀標記
• 外觀（深淺色）、字級、語言等偏好設定

三、資料如何使用

我們僅將上述資料用於：確認並維持你的付費解鎖權益、記住你的偏好。我們不會將你的個人資料販售、出租或分享給第三方作行銷用途。

四、第三方服務

• Apple App Store（App 內購買）：所有付款由 Apple 處理，本服務僅接收 Apple 簽署的交易憑證以確認購買。

本服務不含任何廣告，也不使用第三方分析或追蹤工具（無 tracking）。

五、資料保存與刪除

• 由於採匿名購買，我們僅保存一組交易識別碼與解鎖狀態，不含姓名、電子郵件或任何可識別你本人的資料，也無從連結回你個人，沒有需要刪除的個人資料。
• 換裝置或重新安裝後，可在購買頁的「恢復購買」還原你的解鎖狀態，無需登入、無需再次付費。
• 購買權益屬於你的 Apple ID；刪除本服務資料不影響你向 Apple 申請退款的權利。

六、兒童隱私

本服務不特別針對 13 歲以下兒童設計，也不會刻意蒐集兒童的個人資料。

七、政策變更

若本政策有重大變更，我們會更新本頁頂端的日期。

This App ("the Service") respects your privacy. This policy explains what data we collect, how we use it, and your rights.

1. Data We Collect

Free content requires no sign-in and collects no personal data.

Paid unlock is an anonymous purchase — no sign-in or account registration is required. When you complete a purchase, we store on our server:

• Transaction identifier: the transaction identifier provided by the App Store.
• Unlock status: used to confirm and maintain your entitlement (including revoking it upon a future refund).

We also issue your device an anonymous purchase credential, stored securely on your device. This process does not collect your name, email, or Apple identity. The App does not offer or require sign-in or account registration.

We do not collect: your credit card or payment details (payment is handled entirely by Apple; we never see your payment information), your contacts, location, camera, or photos.

2. Data Stored Only on Your Device

The following is stored only locally on your device and never uploaded to our server:

• Reading progress and read markers
• Preferences such as appearance (light/dark), font size, and language

3. How We Use Data

We use the above solely to: confirm and maintain your paid entitlement and remember your preferences. We do not sell, rent, or share your personal data with third parties for marketing.

4. Third-Party Services

• Apple App Store (In-App Purchase): all payments are handled by Apple; the Service only receives Apple-signed transaction receipts to confirm purchases.

The Service contains no advertising and uses no third-party analytics or tracking.

5. Data Retention and Deletion

• Because purchases are anonymous, we keep only a transaction identifier and unlock status, with no name, email, or any data that identifies you, and no way to link it back to you — so there is nothing personal to delete.
• After switching devices or reinstalling, use Restore Purchases on the purchase screen to restore your unlock — no sign-in and no additional payment required.
• Purchase entitlements belong to your Apple ID; deleting your Service data does not affect your right to request a refund from Apple.

6. Children's Privacy

The Service is not directed at children under 13 and does not knowingly collect their personal data.

7. Changes to This Policy

For material changes, we will update the date at the top of this page.
