# 隱私權政策 (Privacy Policy)
歡迎使用由 [JARC Studio ]（以下簡稱「我們」）開發的 [Math Junior]（以下簡稱「本應用程式」）。本應用程式是一款專為兒童設計的數學學習手機應用程式。我們非常重視使用者的隱私，特別是兒童的網路安全。
本隱私權政策旨在說明我們如何收集、使用、披露及保護使用者的資訊。
## 1. 兒童隱私保護 (Children's Privacy)
本應用程式的目標對象包含 5 至 10 歲的兒童。我們嚴格遵守《兒童網路隱私保護法》(COPPA) 及相關法律法規：
* 我們**不會**蓄意收集、儲存或分享任何 13 歲以下兒童的個人識別資訊（例如：姓名、地址、Email、電話號碼等）。
* 應用程式內的所有遊戲進度與獎勵（如城堡、皇冠）均儲存於使用者的本機裝置中，或以匿名方式處理。
## 2. 資訊的收集與使用
為了提供穩定的服務、優化使用者體驗以及維持營運，我們使用了值得信賴的第三方服務。這些服務可能會收集用於識別您裝置的特定資訊：
* **Google AdMob（廣告服務）：** 本應用程式包含廣告。為了符合兒童保護政策，我們已在程式碼中啟動「兒童導向設定 (TagForChildDirectedTreatment)」。AdMob 將不會針對兒童使用者投放個人化追蹤廣告（不進行行為追蹤），僅會投放非個人化的內容相關廣告。
* **RevenueCat（內購管理）：** 用於處理應用程式內的付費訂閱與購買驗證。RevenueCat 會處理匿名的交易收據資訊，以確認您的 Premium 權限，但不會收集使用者的個人身分資料。
## 3. 資料儲存與安全性
我們採取合理的實體與電子安全措施來保護您的資訊。由於本應用程式的大部分資料（如學習進度）皆儲存於您的本機裝置中，清除 App 快取或刪除 App 可能會導致該資料遺失。我們不會將您的資料出售或分享給任何未授權的第三方。
## 4. 權限要求

# Privacy Policy
Welcome to Math Junior ("the Application"), a children's math learning mobile application developed by JARC Studio ("we," "us," or "our"). We highly value the privacy of our users, especially the online safety of children.
This Privacy Policy explains how we collect, use, disclose, and safeguard your information.
## 1. Children's Privacy Protection
The target audience of this Application includes children aged 5 to 10. We strictly comply with the Children's Online Privacy Protection Act (COPPA) and relevant data protection laws:
* We **do not** knowingly collect, store, or share any personally identifiable information (such as name, address, email, or phone number) from children under 13.
* All game progress and rewards (such as castles and crowns) are stored locally on the user's device or processed anonymously.
## 2. Information Collection and Use
To provide stable services, optimize user experience, and maintain operations, we utilize trusted third-party services. These services may collect information used to identify your device:
* **Google AdMob (Advertising):** This Application contains advertisements. To comply with children's protection policies, we have enabled the "Tag for Child-Directed Treatment" in our code. AdMob will not serve personalized tracking ads (behavioral tracking) to child users; it will only display non-personalized, contextually relevant ads.
* **RevenueCat (In-App Purchases):** Used to manage in-app paid subscriptions and purchase verifications. RevenueCat processes anonymous transaction receipt information to confirm your Premium entitlements but does not collect personally identifiable information.
## 3. Data Storage and Security
We implement reasonable physical and electronic security measures to protect your information. Since most of your data (such as learning progress) is stored locally on your device, clearing the app cache or deleting the app may result in data loss. We do not sell or share your data with unauthorized third parties.
## 4. Permissions Required
This Application may request the following permissions to function properly:
* **Internet Access:** Used to load advertisements and verify RevenueCat in-app purchase status.
## 5. Third-Party Privacy Policy Links
You can review the privacy policies of the third-party service providers we use:
* [Google Play Services Privacy Policy](https://policies.google.com/privacy)
* [Google AdMob Privacy Policy](https://support.google.com/admob/answer/6128543)
* [RevenueCat Privacy Policy](https://www.revenuecat.com/privacy)
## 6. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes. Changes are effective immediately after they are posted on this page.
