到 iPhone「設定 › ScoreTone Pro › 麥克風」確認已開啟。調音器、AI 聲學教練都需要麥克風；音準分析全部在您的手機上完成。
在 App 內「更多功能 › 無廣告」可以選擇買斷或月訂閱。所有功能本來就免費，購買只會移除畫面底部的橫幅廣告。
到「更多功能 › 無廣告」按「回復購買」，使用當初購買的同一個 Apple ID 即可找回。
iPhone「設定 › 您的名字 › 訂閱項目」選擇 ScoreTone Pro 取消，或在 App 內「更多功能 › 無廣告 › 管理訂閱」。請在續訂日至少 24 小時前取消。
練琴日記、成績紀錄、樂譜、設定都只存在您的手機上，沒有帳號、也沒有我們的伺服器；刪除 App 會一併刪除這些資料。「分享」功能是交給 iOS 系統分享選單，由您自己決定傳給誰。
不需要。預設的分析與練習建議都在手機上完成。只有您自己在設定中填入 Google Gemini API Key，才會把「數字統計」送到 Google 取得更多建議，不會傳送錄音本身。
更多資訊請見隱私權政策。
Questions or feedback? Email us at antonyhsiang002@gmail.com. A few common questions are answered below.
Open iPhone Settings › ScoreTone Pro › Microphone and make sure it is on. The tuner and the AI Acoustic Coach need the microphone; all pitch analysis happens on your phone.
In the app go to More › Ad-Free and choose a one-time purchase or a monthly subscription. Every feature is already free — buying only removes the banner ad at the bottom of the screen.
Go to More › Ad-Free and tap Restore Purchases, using the same Apple ID you bought with.
iPhone Settings › your name › Subscriptions › ScoreTone Pro, or in the app via More › Ad-Free › Manage Subscription. Cancel at least 24 hours before the renewal date.
Your practice diary, scores, sheet music and settings stay on your phone only — there are no accounts and no servers of ours. Deleting the app deletes this data. The Share buttons hand content to the iOS share sheet, and you choose who receives it.
No. The default analysis and practice plan run on your phone. Only if you enter your own Google Gemini API key does the app send numeric statistics (never the recording) to Google for extra suggestions.
