LectureASR 是一款幫助學生理解英文課程的 iPhone / iPad app。我們的原則很簡單：你的錄音、逐字稿、翻譯和筆記只存在你的裝置上，我們不收集、不上傳、也看不到任何資料。
LectureASR 沒有帳號系統、沒有後端伺服器、沒有分析工具、沒有廣告。App 不會把任何資訊傳送給開發者或第三方。
App 需要麥克風權限才能錄製課堂聲音。錄音檔以 16 kHz 音訊格式儲存在 app 的專屬資料夾中，僅供你在 app 內回放。刪除課程時，錄音檔會一併刪除。
語音轉文字使用 Apple 的 SpeechAnalyzer 框架，完全在裝置上執行。音訊不會離開你的裝置。第一次使用時，系統會下載英文語音模型（由 Apple 提供）。
英文到繁體中文的翻譯使用 Apple 的 Translation 框架，在裝置上執行。第一次使用時，系統會提示下載翻譯語言包。
課後摘要與術語修正使用 Apple Intelligence 的裝置端模型（Foundation Models 框架），在裝置上執行。逐字稿不會傳送到任何伺服器。此功能需要支援 Apple Intelligence 的裝置。
課程、逐字稿、翻譯、摘要和設定以 SwiftData 儲存在裝置本機。若你開啟 iCloud 裝置備份，這些資料會隨你的裝置備份一起由 Apple 保存，適用 Apple 的隱私權政策。
你可以主動將逐字稿匯出為文字、Markdown 或 PDF 並透過系統分享面板傳送。分享到哪裡、給誰，完全由你決定。
依據 Apple 的說明，Translation 框架可能會回報匿名的使用統計（例如翻譯的語言組合），但不包含翻譯的內容。其他框架的資料處理均在裝置上完成。詳情請參考 Apple 的相關文件。
LectureASR 不收集任何個人資料，因此也不會收集兒童的個人資料。
若政策有所變更，我們會更新本頁並修改上方的日期。

LectureASR is an iPhone / iPad app that helps students follow lectures given in English. Our principle is simple: your recordings, transcripts, translations and notes stay on your device. We do not collect, upload or have access to any of it.
LectureASR has no accounts, no backend servers, no analytics and no advertising. The app never sends any information to the developer or to third parties.
The app needs microphone access to record lectures. Recordings are stored as 16 kHz audio files in the app's private container and are only used for playback inside the app. Deleting a lecture deletes its recording.
Speech-to-text uses Apple's SpeechAnalyzer framework and runs entirely on device. Audio never leaves your device. On first use the system downloads an English speech model provided by Apple.
English to Traditional Chinese translation uses Apple's Translation framework on device. On first use the system asks to download the language pack.
After-class summaries and term correction use Apple Intelligence's on-device model (the Foundation Models framework). Transcripts are never sent to a server. These features require a device that supports Apple Intelligence.
Lectures, transcripts, translations, summaries and settings are stored locally with SwiftData. If you enable iCloud device backup, this data is included in your device backup held by Apple under Apple's privacy policy.
You can export a transcript as text, Markdown or PDF through the system share sheet. Where it goes is entirely your choice.
According to Apple, the Translation framework may report anonymous usage metrics (such as the language pair) that do not include the translated content. All other processing happens on device. Please refer to Apple's documentation for details.
LectureASR collects no personal data from anyone, including children.
If this policy changes, we will update this page and the date above.
