「幫助聽」隱私權政策

生效日期：2026 年 8 月 17 日

由 MRJC 開發的「幫助聽」（HearingFriend，下稱「本 App」）是把周圍說話聲即時變成字幕、並可放大到耳機的輔助工具。本 App 的設計原則是：所有個人資料只留在您的手機裡。

我們不收集任何資料

本 App 沒有帳號系統、沒有廣告、沒有分析追蹤工具，不會把您的任何資料傳送給開發者或任何第三方。

在您手機本機處理的資料

• 語音：麥克風收到的聲音即時在手機上辨識成文字，聲音本身不會被儲存、也不會上傳。辨識全程離線（使用下載到手機的離線模型時）。
• 對話紀錄：辨識出的字幕文字保存在手機本機，保留 30 天後自動刪除；您也可以隨時在 App 內逐句刪除。
• 聲紋（選用功能）：若您啟用「認得我的聲音」，App 會將您唸的 3 句話轉成聲音特徵數值（不保存錄音本身），只存在手機本機，用於分辨字幕是不是您自己說的話；可隨時在 App 內刪除。
• 常用詞與改字紀錄：您新增的詞彙與修正，只存在手機本機。

本 App 已停用 Android 的雲端備份與裝置轉移備份，上述資料不會被備份到 Google 雲端。

網路的唯一用途

本 App 只在「下載離線辨識模型」時連線（來源為 Hugging Face 與 GitHub 的公開檔案）。連線時這些網站會如同一般網頁瀏覽看到您的 IP 位址；本 App 不會在連線中夾帶任何個人資料。模型下載完成後，字幕功能完全不需要網路。

App 權限

• 麥克風：把說話聲變成字幕、耳機擴音、聲紋設定。
• 通知：顯示「聆聽進行中」的狀態通知。
• 網路：僅供下載離線模型。

兒童

本 App 並非以兒童為對象設計。

HearingFriend — Privacy Policy

Effective date: August 17, 2026

HearingFriend (“the app”), developed by MRJC, turns nearby speech into live captions and can amplify it to your headphones. The app is built on one principle: all personal data stays on your phone.

We collect nothing

The app has no accounts, no ads, and no analytics or tracking. It never sends your data to the developer or to any third party.

Data processed on your device only

• Audio: sound from the microphone is transcribed on the device in real time. The audio itself is never stored or uploaded. Recognition runs fully offline once an offline model is installed.
• Conversation history: caption text is stored locally, kept for 30 days and then deleted automatically; you can also delete any line in the app at any time.
• Voiceprint (optional): if you enable “Recognize my voice”, the app converts three spoken sentences into numeric voice features (the recordings themselves are not kept), stored locally and used only to tell your own speech apart. You can delete it in the app at any time.
• My words and corrections: stored locally only.

Android cloud backup and device-to-device transfer are disabled for this app, so none of the above is backed up to Google servers.

The only use of the network

The app connects to the internet only to download offline recognition models (public files on Hugging Face and GitHub). Those sites see your IP address as with any web download; the app attaches no personal data. Once models are downloaded, captions work entirely without a connection.

App permissions

• Microphone: captions, headphone boost, and voiceprint setup.
• Notifications: the “listening” status notification.
• Internet: model downloads only.

Children

The app is not designed for or directed at children.
