ScoreTone Pro 隱私權政策

ScoreTone Pro（以下稱「本 App」）是一款調音器、節拍器、音叉產生器、AI 聲學教練與聽覺訓練工具。我們非常重視您的隱私，本政策說明本 App 如何處理您的資料。

1. 麥克風、相機與相簿存取

本 App 需要存取您裝置的麥克風，用於：

• 即時偵測樂器或歌聲音高（調音器功能）
• 「AI 聲學教練」錄音評測與回放

麥克風只在需要時才開啟（調音器頁面、樂譜閱讀器的小調音器、錄音與訓練），離開這些功能後約幾秒內就會關閉，App 退到背景時也會立刻關閉（錄音或訓練進行中除外）；本 App 不會在背景持續聆聽。第一次用到時系統才會詢問授權。

所有音準分析都在您的裝置上即時完成，錄下的音訊只保存在裝置本機記憶體中用於回放，本 App 本身不會將您的錄音上傳到任何伺服器，也沒有任何後端會儲存或存取您的錄音內容。關閉 App 或結束錄音回放後，錄音資料即從記憶體中釋出。（若您主動使用第 3 節的「分享」功能傳送錄音檔，則由您自行決定傳給誰。）

相機與相簿：只有在您於「樂譜」匯入圖片、並選擇「拍照」或從相簿挑選照片時才會使用。匯入的照片與 PDF 只儲存在您裝置的本機資料庫（IndexedDB），不會上傳，也不會被我們存取。

2. AI 聲學教練與 Gemini API（選用功能）

重點摘要：

預設情況	全部在您的裝置上處理。不會上傳任何錄音、聊天文字、樂譜或練習紀錄；沒有帳號，也沒有開發者的伺服器。
選用的第三方 AI 服務	Google LLC 的 Gemini API。只有在您自行貼上 Gemini 金鑰時才會使用；本 App 沒有內建任何金鑰。
傳送什麼	您在教練追問與咕嚕嚕博士聊天中輸入的文字；練琴統計數字（練習分鐘數、連續天數、評測分數與最弱項目、音準偏差等）；您告訴博士的稱呼與樂器；您選的對照樂譜名稱與對譜結果。永遠不會傳送錄音檔、樂譜檔或照片。
什麼時候傳送	只有在您貼上金鑰、並在 App 跳出的「資料傳送說明」視窗按下「同意」之後。沒有金鑰，或沒有按同意，就不會傳送任何東西。
用途	只用來產生教練與博士的回覆文字；本 App 不把這些資料用於廣告、行銷或建立個人檔案。
對方如何保護	資料由 Google 依 Gemini API 的條款與 Google 隱私權政策處理。免費金鑰與付費金鑰的條款不同：使用免費金鑰時，Google 可能把內容用於改進產品，也可能有人工審閱，所以請不要輸入個人隱私資料。本 App 的開發者看不到這些資料。
如何停止	設定 › AI 與連線 › 「撤回同意並清除金鑰」；或把金鑰欄位清空並儲存。之後再次貼上金鑰時，會重新請您同意。
年齡	Google 規定使用者需年滿 18 歲；未成年請由家長協助，或只使用離線模式。

「AI 聲學教練」預設會在裝置本機，使用簡單規則式演算法產生分析報告，完全不需要網路連線。

若您自願在設定中輸入自己的 Google Gemini API Key，本 App 會在每次錄音結束後，將「音準飄移、穩定度百分比、抖動幅度」等純數字統計資料直接從您的裝置傳送至 Google 的 Gemini API，換取更聰明的教練建議文字。此過程：

• 不會傳送您的錄音音檔本身，只傳送數字統計
• 若您在助手裡打字追問，您輸入的問題文字、您自行填寫的曲目名稱，以及「常出錯的音名與偏差音分」這類統計，也會一併送出；請不要在其中輸入個人隱私資料
• 咕嚕嚕博士（貓頭鷹聊天）：預設使用裝置上的離線對話，不會連網。只有在您自行填入 Gemini API Key 之後，您輸入的聊天內容，以及一份練琴摘要（例如今天與本週練習分鐘數、連續天數、最近的評測分數與最弱項目、您告訴博士的稱呼與樂器）才會從您的裝置直接送到 Google 的 Gemini API；聊天記錄只儲存在您的裝置本機，我們看不到。請不要在聊天中輸入個人隱私資料。博士只是娛樂與練習輔助，不提供醫療或專業諮詢。首次啟用 Gemini 前（儲存金鑰時），App 會顯示「資料傳送說明」，您同意後才會傳送；不同意則一切維持離線
• 直接由您的裝置連線至 Google 伺服器，本 App 開發者不會經手或儲存這些資料
• 使用您自行填寫、僅儲存在您裝置本機（localStorage）的 API Key，我們不會收集您的 API Key
• 受 Google 隱私權政策規範

您可以隨時在設定中清空 API Key 欄位並儲存，即可停用此功能，恢復為純本機分析。

3. 分享功能（由您主動操作）

App 內的「分享」按鈕會呼叫 iOS 系統內建的分享選單（或 LINE 的分享連結），把您選定的內容——成績卡圖片、文字摘要、完整報告、練琴日記、這次的錄音檔，或老師用的作業／聯絡本卡片——交給您自己挑選的 App 與對象（例如 LINE 群組）。

• 只有在您按下分享、並於系統選單中選好對象之後，內容才會離開您的裝置
• 內容是直接從您的裝置交給您選的 App；本 App 沒有伺服器，不會經手、儲存或轉傳
• 分享出去的內容，之後受您所選的 App（例如 LINE）的隱私權政策規範

3-1. iCloud 備份（選用，預設關閉）

您可以在「設定 › 備份與換機」開啟「iCloud 自動備份」。開啟後，App 會把您的樂譜（含標記）、練琴紀錄與曲目、以及設定，寫進您自己的 iCloud 雲碟中本 App 專屬的資料夾（檔案 App › iCloud 雲碟 › ScoreTone Pro），並依您設定的頻率更新。

• 資料由 Apple 依您的 Apple 帳號與 iCloud 設定儲存與同步，使用您自己的 iCloud 空間；本 App 沒有伺服器，我們無法讀取、儲存或轉傳這些資料
• 可以隨時在設定關閉；已經存在 iCloud 的檔案可以在檔案 App 自行刪除
• Gemini 金鑰與購買狀態不會被備份

4. 廣告與「無廣告」購買

本 App 在畫面底部顯示由 Google AdMob 提供的橫幅廣告；購買「無廣告」後不再顯示。

• 兒童導向處理：廣告請求已啟用「兒童導向處理」，只會顯示非個人化、內容分級為一般觀眾（G）的廣告，不使用廣告識別碼（IDFA）追蹤您，也不會跳出追蹤授權詢問
• 為了投放廣告、計費與防止詐欺，AdMob 仍可能處理 IP 位址、裝置與 App 資訊等，詳見 Google 廣告政策
• 「無廣告」買斷與月訂閱的付款完全由 Apple 處理，我們看不到您的付款資料；App 只會向 Apple 查詢「是否已購買」。本 App 沒有帳號與伺服器，不會建立或儲存您的購買紀錄

5. 我們收集的其他資料

本 App 沒有使用者帳號、沒有分析追蹤工具（Analytics/Tracking SDK），App 本身不會收集裝置識別碼（廣告服務的處理方式見第 4 節）。以下項目僅儲存於您裝置本機的瀏覽器儲存空間（localStorage），不會離開您的裝置：

• 語言與主題外觀偏好設定
• A4 基準頻率設定
• 練琴日記、練習紀錄與歷史分數、寵物進度、與咕嚕嚕博士的聊天記錄與設定
• 樂譜庫：您匯入的 PDF／圖片、手寫標記、頁面筆記、書籤與分類資料（存在本機資料庫 IndexedDB）
• 練琴提醒（選用）：提醒時間與日期只存在本機，通知由 iOS 在你的裝置上排程與顯示，不經過任何伺服器；自動記錄練琴時長只把累計時間寫進你本機的練琴日記，不上傳
• 備份檔（選用）：您按下「備份」時，App 會把樂譜、練習紀錄與設定打包成一個檔案，交給 iOS 分享選單，由您自己選擇存放位置（例如 iCloud Drive）。檔案不會經過我們的伺服器，也不含 Gemini 金鑰與購買狀態
• 字體、工具列位置與 Apple Pencil 手勢等介面偏好
• 老師卡片上次填寫的班級名稱與署名
• （若您有設定）Gemini API Key

6. 兒童隱私

本 App 不會刻意收集兒童個人資料。為保護兒童，廣告請求已啟用「兒童導向處理」（見第 4 節）：只顯示非個人化、內容分級為一般觀眾的廣告，不使用廣告識別碼追蹤使用者。

7. 政策異動

若本政策內容有重大變更，我們會更新本頁面上方的「最後更新」日期。

8. 商標與第三方聲明

Apple、iPhone、iPad、Apple Pencil、iCloud 與 AirDrop 是 Apple Inc. 的商標；Google、Gemini 與 AdMob 是 Google LLC 的商標；LINE 與其他產品名稱為各自權利人所有。本 App 與這些公司沒有隸屬、贊助或背書關係，名稱僅用來說明相容性與資料的流向。

本 App 使用開放原始碼元件：PDF.js（Mozilla，Apache-2.0）、Capacitor（Ionic，MIT）、capacitor-community/admob（MIT）、capacitor/local-notifications（MIT）、capgo/native-purchases（MPL-2.0）；授權全文可在 App 內「設定 → 開放原始碼與商標聲明」查看。

ScoreTone Pro Privacy Policy

ScoreTone Pro (the "App") is an acoustic tuner, metronome, tone generator, AI acoustic coach, and ear-training tool. We take your privacy seriously. This policy explains how the App handles your data.

1. Microphone, Camera & Photos Access

The App requests access to your device's microphone in order to:

• Detect the pitch of your instrument or voice in real time (Tuner)
• Record and play back short clips for the "AI Acoustic Coach" feature

The microphone is turned on only while it is needed (the Tuner page, the score reader's mini tuner, recording and training) and is switched off within a few seconds after you leave those features, and immediately when the App goes to the background (except while a recording or training session is running). The App never listens in the background. The system asks for permission the first time it is needed.

All pitch analysis happens locally on your device in real time. Recorded audio is kept only in your device's local memory for playback and is never uploaded by the App to any server we operate. Recordings are released from memory once you close the app or start a new recording. (If you choose to send a recording with the Share feature described in Section 3, you decide who receives it.)

Camera & Photos: used only when you import images into Sheet Music and choose "Take Photo" or pick pictures from your library. Imported photos and PDFs are stored only in a local database on your device (IndexedDB); they are never uploaded and we never have access to them.

2. AI Acoustic Coach & the Gemini API (Optional)

Summary:

By default	Everything is processed on your device. No recordings, chat text, scores or practice records are uploaded; there are no accounts and no developer server.
Optional third-party AI service	Google LLC's Gemini API. It is used only if you paste your own Gemini key; the App ships without any key.
What is sent	The text you type in coach follow-ups and in the chat with Dr. Hootsy; practice statistics (minutes practiced, streak, evaluation scores and weakest area, pitch deviation numbers); the name and instrument you told the owl; the name and results of a reference score you picked. Recordings, score files and photos are never sent.
When it is sent	Only after you paste a key and tap "Agree" in the data-sharing notice the App shows. Without a key, or without your agreement, nothing is sent.
Why	Only to generate the coach's and the owl's reply text; the App does not use this data for advertising, marketing or profiling.
How the recipient protects it	Google processes the data under the Gemini API terms and Google's Privacy Policy. Terms differ between free and paid keys: with a free key, Google may use content to improve its products and humans may review it, so please do not enter personal information. The App's developer cannot see this data.
How to stop	Settings › AI & connection › "Withdraw consent and clear key", or clear the key field and save. If you paste a key again later, you are asked to agree again.
Age	Google requires users to be 18 or older; minors should ask a parent for help or stay offline.

By default, the AI Acoustic Coach generates its report entirely on-device using a simple rule-based algorithm, with no network connection required.

If you voluntarily enter your own Google Gemini API key in Settings, the App will send numeric performance statistics only (pitch drift, stability percentage, fluctuation) — never your raw audio recording — directly from your device to Google's Gemini API after each session, in exchange for a more insightful, AI-generated coaching report. In this flow:

• Your raw audio recording is never transmitted — only aggregate numbers
• If you type a follow-up question in the Assistant, the question text, the piece name you entered, and statistics such as which notes are often off (and by how many cents) are sent too — please do not type personal information there
• Dr. Hootsy (the owl chat): by default the owl chats entirely on your device, with no network use. Only after you enter your own Gemini API key are the messages you type, plus a short practice summary (e.g. minutes practiced today and this week, streak, latest evaluation score and weakest area, and the name and instrument you told the owl) sent directly from your device to Google's Gemini API. The chat history is stored only on your device and we cannot see it. Please do not type personal information in the chat. The owl is for entertainment and practice support and does not give medical or professional advice. The first time you enable Gemini (when saving a key), the app shows a data-sharing notice and sends nothing until you agree; if you decline, everything stays offline
• Your device connects directly to Google's servers; the App's developer does not see, receive, or store this data
• Your API key is entered by you and stored only in your device's local storage (localStorage); we never collect it
• This exchange is governed by Google's Privacy Policy

You can disable this feature at any time by clearing the API key field in Settings and saving, which reverts the coach to fully offline analysis.

3. Sharing (Started by You)

The in-app Share buttons open the iOS system share sheet (or a LINE share link) to hand content you choose — a score card image, a text summary, the full report, a practice-diary entry, the recording of a take, or a teacher's homework/notice card — to the app and people you pick, such as a LINE group.

• Content leaves your device only after you tap Share and choose a recipient in the system sheet
• It goes straight from your device to the app you chose; the App has no server and never sees, stores or forwards it
• Once shared, the content is governed by the privacy policy of the app you chose (for example LINE)

3-1. iCloud Backup (Optional, Off by Default)

You can turn on "iCloud auto backup" in Settings › Backup & new phone. When on, the App writes your scores (with markings), practice records and pieces, and settings to a folder that belongs to this App in your own iCloud Drive (Files app › iCloud Drive › ScoreTone Pro), updating it at the frequency you choose.

• The data is stored and synced by Apple under your Apple account and iCloud settings, using your own iCloud storage; the App has no server, and we cannot read, store or forward it
• You can turn it off at any time in Settings; files already in iCloud can be deleted in the Files app
• The Gemini key and purchase status are never backed up

4. Advertising & the "Ad-Free" Purchase

The App shows a banner ad served by Google AdMob at the bottom of the screen; it is removed once you buy "Ad-Free".

• Child-directed treatment: ad requests are tagged for child-directed treatment, so only non-personalized ads rated for general audiences (G) are shown, the advertising identifier (IDFA) is not used to track you, and no tracking permission prompt is shown
• To deliver ads, bill advertisers and prevent fraud, AdMob may still process information such as your IP address and device/app details — see Google's advertising policies
• Payments for the lifetime and monthly "Ad-Free" options are handled entirely by Apple; we never see your payment details. The App only asks Apple whether you have purchased it. The App has no accounts and no server, so we do not create or store purchase records

5. Other Data We Collect

The App has no user accounts and no analytics/tracking SDKs, and the App itself does not collect device identifiers (see Section 4 for how the ad service works). The following items are stored only in your device's local browser storage (localStorage) and never leave your device:

• Language and theme preferences
• A4 tuning reference frequency
• Practice diary, session history and scores, pet progress, and your chat history and settings with Dr. Hootsy
• Your score library: imported PDFs / images, ink marks, page notes, bookmarks and categories (stored in the local IndexedDB database)
• Practice reminders (optional): the reminder time and days are stored only on your device; notifications are scheduled and shown by iOS locally, with no server involved. Automatic practice-time tracking only writes the accumulated time to your local practice diary and never uploads it
• Backup file (optional): when you tap Backup, the app packs your scores, practice records and settings into one file and hands it to the iOS share sheet; you choose where it is saved (for example iCloud Drive). It never passes through our servers and does not contain your Gemini key or purchase status
• Interface preferences such as font, toolbar position and Apple Pencil gestures
• The class name and signature last used on teacher cards
• Your Gemini API key, if you choose to set one

6. Children's Privacy

The App does not knowingly collect personal information from children. To protect children, ad requests use child-directed treatment (see Section 4): only non-personalized, general-audience ads are shown and the advertising identifier is not used to track users.

7. Changes to This Policy

If we make material changes to this policy, we will update the "Last updated" date above.

8. Trademarks & Third-Party Notices

Apple, iPhone, iPad, Apple Pencil, iCloud and AirDrop are trademarks of Apple Inc.; Google, Gemini and AdMob are trademarks of Google LLC; LINE and other product names belong to their respective owners. The App is not affiliated with, sponsored by or endorsed by these companies; the names are used only to describe compatibility and data flow.

The App uses open-source components: PDF.js (Mozilla, Apache-2.0), Capacitor (Ionic, MIT), capacitor-community/admob (MIT), capacitor/local-notifications (MIT) and capgo/native-purchases (MPL-2.0). Full license texts are available in the App under Settings → Open-source & trademark notices.

The chibi composer covers are original cartoon artwork created for the App and depict only historical figures who died more than 70 years ago; modern and living musicians are shown as a generic note character, which is not a likeness of any person and does not imply their (or their estates') permission, sponsorship or involvement.
