TraceIt ("the App") is made by an independent developer. This document explains what information the App accesses, how it is used, and what it does not do.
The App's core feature is showing a live camera preview so you can overlay a reference image and trace it. The camera feed is only used for real-time display — it is never recorded, saved, or uploaded anywhere.
When you use the "Pick Image" feature, the App only receives the single photo you select, via Android's built-in photo picker (the App does not get broad access to your photo library). That image stays in memory only while the App is running, used solely as the tracing overlay. It is never saved to storage or uploaded, and disappears once you close the App.
The App is free to use and supported by ads, currently served through Google AdMob. To serve and measure ads, AdMob and its advertising partners may collect:
This data is handled by Google under its own privacy policy; the App's developer does not separately collect or retain it. See:
The App requests network permissions to load ads and to check whether an internet connection is available (showing a prompt if it is not). This check happens entirely on your device and is never sent to any server.
The App does not require an account and does not collect your name, email address, or password.
Other than the AdMob data described above, which Google handles under its own policy, the developer does not sell or share your data with any third party.
The App is not directed at children under 13, and the developer does not knowingly collect personal information from children.
If the App adds new advertising services or features that change how data is collected, this policy will be updated accordingly, along with the date above.

TraceIt（以下稱「本 App」）由個人開發者製作。這份文件說明本 App 會接觸到哪些資訊、怎麼使用，以及不會做什麼。
本 App 的核心功能是把相機畫面即時顯示出來，讓你疊上參考圖描繪。相機畫面只用來即時顯示，不會被錄影、拍照存檔，也不會上傳到任何地方。
當你透過「選圖」功能挑選一張照片時，本 App 只會拿到你選定的那一張圖片（透過 Android 系統內建的相片選擇器，本 App 不會取得你手機相簿的完整存取權限）。這張圖片只會保留在 App 執行期間的記憶體裡，用來當作描圖的疊圖，不會被儲存、不會被上傳、關閉 App 後就會消失。
本 App 免費提供，透過顯示廣告維持運作，廣告服務目前由 Google AdMob 提供。為了顯示和衡量廣告成效，AdMob 及其合作的廣告商可能會收集：
這些資料由 Google 依照其自身的隱私權政策處理，本 App 開發者不會另外取得或保存這些資料。詳情請參考：
本 App 需要網路權限來載入廣告，以及偵測目前有沒有網路連線（沒有網路時會提示你開啟網路才能繼續使用）。這個偵測完全在你的裝置上進行，不會把偵測結果傳送給任何伺服器。
本 App 不需要註冊帳號，也不會向你收集姓名、電子郵件、密碼等個人資料。
除了上述 AdMob 廣告服務依其自身政策收集的資料之外，本 App 開發者不會將你的任何資料出售或分享給其他第三方。
本 App 並非特別針對 13 歲以下兒童設計，開發者不會刻意收集兒童的個人資料。
如果本 App 未來新增其他廣告服務或功能而影響資料蒐集方式，這份政策會一併更新，並修改上方的最後更新日期。
