隱私權政策

最後更新：2026 年 11 月 16 日

ReHarmo 由粗糙空間創意有限公司（RoughZone Creative，以下稱「我們」）開發。這份政策用白話說明 ReHarmo 會碰到你的哪些資料。重點先講：不登入的話，你的歌只存在你自己的裝置上，我們看不到。ReHarmo 沒有廣告、不追蹤你、也沒有使用任何數據分析工具。

1. 這份政策適用於什麼

適用於 ReHarmo 的 iPhone、iPad、Android App，以及官網 reharmo.roughzone.tw。

2. 存在你裝置上的資料

你輸入的歌（歌名、旋律、和弦、歌詞、段落）、重配的結果、保留的版本，以及 App 的設定，都存在你的裝置上。不登入的話，這些資料不會離開你的裝置。配和弦的運算也全部在裝置上完成，不需要網路。

3. 會離開裝置的資料

只有在你主動做下面這些事的時候，才會有資料離開裝置：

登入帳號（用 Google 或 Apple 登入）：我們會取得你的電子郵件地址、顯示名稱，以及一組帳號編號，用來認出你是誰。登入服務由 Google 的 Firebase Authentication 提供。用 Apple 登入時你可以選擇隱藏真實的電子郵件地址。
雲端同步（Pro 功能，需要登入）：你的歌曲內容（歌名、旋律、和弦、歌詞、段落、重配結果）與歌曲群組會上傳到 Google 的 Cloud Firestore，存放在台灣的資料中心。每個帳號只能讀寫自己的資料。
購買 Pro：付款由 Apple 或 Google 處理，我們拿不到你的信用卡或付款資料。我們透過 RevenueCat 得知「這個帳號買了哪個方案、到什麼時候」，用來開啟 Pro 功能。沒有登入時，RevenueCat 用一組匿名編號記錄。
寄信給我們：你用「意見回饋」寄信時，信裡會自動帶上 App 版本與裝置型號，方便我們排查問題。你可以在寄出前刪掉。

Google（Firebase）與 RevenueCat 是替我們處理資料的服務供應商。我們不會把你的資料賣給任何人，也不會提供給廣告商。

4. 我們要求的權限

麥克風：只有在你按下「用唱的或彈的」時才會使用，用來把你哼唱或彈奏的聲音轉成音符。聲音只在你的裝置上即時處理，不會錄下來、不會儲存、也不會上傳。
藍牙（iPhone、iPad）：只用來連接藍牙 MIDI 鍵盤。
網路：只在登入、雲端同步、查詢或購買 Pro 時使用。

5. 我們不做的事

沒有廣告。
不追蹤你，不跨 App 或網站蒐集你的行為。
不使用數據分析或當機回報工具。
不會用你的歌來訓練 AI。ReHarmo 的和聲引擎是固定的樂理規則，不是 AI 模型。

6. 保存與刪除

裝置上的資料：刪除某首歌、或移除 App，就會從裝置上刪掉。
雲端的資料與帳號：在 App 的「設定 → 帳號與方案 → 刪除帳號」可以隨時刪除，雲端上的歌和帳號會一起刪掉。不方便用 App 的話，也可以照刪除帳號與資料那一頁的說明寫信給我們。
購買紀錄：Apple、Google 與 RevenueCat 會依各自的規定保存交易紀錄（例如稅務與退款所需）。刪除帳號不會自動取消訂閱，請另外到 App Store 或 Google Play 取消。

7. 兒童

ReHarmo 不是專為 13 歲以下兒童設計的，我們不會刻意蒐集兒童的個人資料。如果你發現兒童在沒有監護人同意的情況下建立了帳號，請寫信給我們，我們會把它刪除。

8. 政策變更

如果 ReHarmo 處理資料的方式有變動，我們會更新這一頁與上面的日期。重大的變更會在 App 內提醒。

9. 聯絡我們

對這份政策或你的資料有任何問題，請寫信到 contact@roughzone.tw。

Privacy Policy

Last updated: November 16, 2026

ReHarmo is made by RoughZone Creative Co., Ltd. (“we”). This policy explains in plain language what data ReHarmo touches. The short version: if you don’t sign in, your songs stay on your device and we can’t see them. ReHarmo has no ads, does not track you, and uses no analytics tools.

1. Scope

This policy covers the ReHarmo apps for iPhone, iPad and Android, and the website reharmo.roughzone.tw.

2. Data stored on your device

The songs you enter (titles, melody, chords, lyrics, sections), the reharmonized results, saved versions and your settings are stored on your device. Unless you sign in, none of it leaves your device. All reharmonization runs on the device and works offline.

3. Data that leaves your device

Data leaves your device only when you choose to do one of the following:

Sign in (with Google or Apple): we receive your email address, display name and an account ID so we can recognize you. Sign-in is provided by Google’s Firebase Authentication. With Sign in with Apple you can choose to hide your real email address.
Cloud sync (a Pro feature that requires sign-in): your song content (titles, melody, chords, lyrics, sections, reharmonized results) and song groups are uploaded to Google Cloud Firestore and stored in a data center in Taiwan. Each account can read and write only its own data.
Buying Pro: payment is handled by Apple or Google; we never receive your card or payment details. Through RevenueCat we learn which plan an account bought and until when, so we can unlock Pro. If you are not signed in, RevenueCat uses an anonymous ID.
Emailing us: when you use “Send feedback”, the email is pre-filled with the app version and device model to help us investigate. You can delete it before sending.

Google (Firebase) and RevenueCat act as our service providers. We do not sell your data to anyone or share it with advertisers.

4. Permissions

Microphone: used only when you tap “Sing or play it”, to turn your humming or playing into notes. Audio is processed live on your device. It is not recorded, stored or uploaded.
Bluetooth (iPhone, iPad): used only to connect Bluetooth MIDI keyboards.
Network: used only for sign-in, cloud sync, and checking or buying Pro.

5. What we don’t do

No ads.
No tracking across apps or websites.
No analytics or crash-reporting tools.
We do not use your songs to train AI. ReHarmo’s harmony engine is a fixed set of music-theory rules, not an AI model.

6. Retention and deletion

On-device data: deleting a song, or removing the app, deletes it from the device.
Cloud data and your account: you can delete them at any time in the app under “Settings → Account & plan → Delete account”. Your cloud songs and the account are removed together. If you can’t use the app, follow the steps on the Delete account & data page to email us.
Purchase records: Apple, Google and RevenueCat keep transaction records as their own rules require (for example for tax and refunds). Deleting your account does not cancel a subscription; cancel it separately in the App Store or Google Play.

7. Children

ReHarmo is not directed to children under 13 and we do not knowingly collect their personal data. If you believe a child has created an account without a guardian’s consent, email us and we will delete it.

8. Changes

If the way ReHarmo handles data changes, we will update this page and the date above. Significant changes will also be announced in the app.

9. Contact
