Privacy Policy
InTone is a vocal practice app. This policy explains what data the app handles, why it is used, and how you can control it.
Summary
InTone does not include advertising, ad tracking, or third-party analytics. Most practice data stays on your device. If you enable iCloud backup, selected practice data is stored in your own iCloud account so you can restore it on another device. The developer does not operate a general user-data server for the core app features.
Data handled by the app
Apple Sign In: If you sign in with Apple, the app stores your Apple user identifier on your device. If Apple provides your name or email address during sign-in, the app may store those values locally so your account status can be shown in the app. This Apple account record is not included in InTone's iCloud backup payload.
Microphone and recordings: If you use recording features, the app requests microphone permission. Your practice recordings are saved locally on your device and are used for playback, self-review, pitch review, and progress tracking. Recordings are not uploaded by the core app. If you enable iCloud backup, recording files may be copied to your own iCloud container.
Practice records: The app stores practice sessions, exercise settings, clip annotations, reflections, practice plans, teacher-style submissions and feedback, imported score data, and related metadata locally in the app. If you enable iCloud backup, these records may be copied to your own iCloud container.
iCloud backup: iCloud backup is optional. When enabled, InTone writes a backup manifest and recording files to the iCloud container associated with your Apple account. Apple provides and processes iCloud services under Apple's terms and privacy policy. The developer does not access your private iCloud backup data.
Subscriptions and purchases: Paid access is handled through Apple's StoreKit and App Store subscriptions. Apple processes payment information. InTone reads subscription entitlement status and stores local trial/subscription state, but the developer does not receive your payment card details.
Customer support: If you email support, the developer receives your email address, your message, and any information you choose to include. The app's support email draft may include app version, build number, device model, and OS version to help diagnose issues. If the Mail app is unavailable, InTone may copy the support email address to the system pasteboard; it does not read your pasteboard.
How data is used
Data is used to provide app functionality: vocal warm-up playback, custom score creation, recording playback, pitch review, progress reports, iCloud restore, account display, purchase access, and support. InTone does not use your data for third-party advertising or tracking.
Retention and deletion
Local app data remains on your device until you delete it in the app where available, reset the relevant feature, delete local account data, or delete the app. iCloud backup data remains in your iCloud account until you remove it from iCloud, delete the app's iCloud documents, or use the app's delete local data and iCloud backup action. You can sign out of Apple Sign In inside the app to remove the locally stored Apple account record.
Support emails are retained only as long as needed to respond to your request and maintain support history.

隐私政策
InTone 是一款练声 App。本政策说明 App 会处理哪些数据、为什么使用这些数据，以及你可以如何控制。
概要
InTone 不包含广告、广告追踪或第三方分析。大多数练习数据保存在你的设备本地。如果你开启 iCloud 备份，部分练习数据会保存到你自己的 iCloud 账户中，方便你在另一台设备恢复。核心功能目前没有使用开发者可访问的通用用户数据服务器。
App 处理的数据
Apple 登录：如果你使用 Apple 登录，App 会在本地保存 Apple 用户标识符。如果 Apple 在登录时提供姓名或邮箱，App 可能会在本地保存这些信息，用于显示账号状态。这份 Apple 账号记录不会包含在 InTone 的 iCloud 备份内容中。
麦克风和录音：如果你使用录音功能，App 会请求麦克风权限。你的练习录音保存在设备本地，用于回放、自我复盘、音准复盘和进步记录。核心 App 不会上传录音。如果你开启 iCloud 备份，录音文件可能会复制到你自己的 iCloud 容器中。
练习记录：App 会在本地保存练习会话、练习设置、片段标注、复盘、练习计划、提交与反馈、导入的曲谱数据和相关元数据。如果你开启 iCloud 备份，这些记录可能会复制到你自己的 iCloud 容器中。
iCloud 备份：iCloud 备份是可选功能。开启后，InTone 会把备份清单和录音文件写入与你 Apple 账号关联的 iCloud 容器。iCloud 服务由 Apple 提供并处理。开发者无法访问你的私人 iCloud 备份数据。
订阅和购买：付费访问通过 Apple StoreKit 和 App Store 订阅处理。Apple 处理付款信息。InTone 会读取订阅权益状态并保存本地试用/订阅状态，但开发者不会收到你的银行卡或支付卡信息。
客户支持：如果你发送支持邮件，开发者会收到你的邮箱地址、邮件内容，以及你自愿提供的信息。支持邮件草稿可能包含 App 版本、构建号、设备型号和系统版本，以便定位问题。如果系统邮件 App 不可用，InTone 可能会把支持邮箱复制到系统剪贴板；App 不会读取你的剪贴板。
数据用途
数据用于提供 App 功能：练声播放、自定义曲谱创建、录音回听、音准复盘、进步报告、iCloud 恢复、账号显示、购买访问和客户支持。InTone 不会将你的数据用于第三方广告或追踪。
保留和删除
本地 App 数据会保留在你的设备上，直到你在 App 内删除、重置相关功能、删除本地账号数据，或删除 App。iCloud 备份数据会保留在你的 iCloud 账户中，直到你从 iCloud 中移除、删除 App 的 iCloud 文档，或使用 App 的删除本机数据和 iCloud 备份操作。你可以在 App 内退出 Apple 登录，以移除本地保存的 Apple 账号记录。
支持邮件只会在回复你的请求和维护支持历史所需的时间内保留。
