你的练习声音,只留在你的设备上
吉他工具(GuitarTool)隐私政策 · 更新日期:2026 年 8 月 22 日
卫智超(以下简称“开发者”)重视你的隐私。本政策说明 GuitarTool 在调音、节拍练习、和弦查询、主屏幕小组件和 Apple Watch 功能中如何处理信息。
1. 我们不收集哪些信息
GuitarTool 不收集、出售或分享个人信息。本应用无需注册或登录,不收集姓名、邮箱、电话号码、精确位置、通讯录、照片、设备广告标识符或使用行为分析数据,也不集成广告、分析或第三方追踪 SDK。
2. 麦克风与音频处理
只有当你主动启动调音器时,应用才会请求麦克风权限。麦克风音频用于在设备上实时计算音高、音分、信号强度和稳定度。
- 音频完全在设备本地处理,不会发送到开发者或任何第三方服务器。
- 麦克风录音不会保存到文件、相册、iCloud 或其他持久存储。
- 停止调音、切换功能或应用进入后台后,实时采集会停止,分析缓冲会被释放。
- 你可以在 iOS“设置”中随时撤销麦克风权限;撤销后只有调音器无法使用。
3. 本地设置与 App Group
为了记住你的练习环境,应用会在设备上保存节拍器速度、拍号、训练方案、调音预设、主题和界面语言等设置。部分节拍器状态通过 Apple App Group 在 GuitarTool 与其主屏幕小组件之间共享,以便小组件显示和控制同一套本地设置。
4. 网络、第三方服务与追踪
GuitarTool 的核心功能不需要网络连接。应用不包含第三方广告、分析或追踪服务,不创建用户画像,也不进行跨应用或跨网站追踪。
本隐私政策网页本身不加载外部字体、分析脚本或追踪像素,不设置 Cookie。语言切换只改变当前页面显示,不会向服务器发送偏好。
5. 儿童隐私
GuitarTool 不以收集儿童信息为目的,也不会故意收集儿童或其他用户的个人信息。由于应用不提供账户、社交或数据上传功能,儿童使用时不会因此向开发者提交个人资料。
6. 数据安全与你的选择
最小化数据是本应用的主要保护方式:音频不上传、不留存,练习设置只保存在 Apple 平台提供的本地存储中。你可以通过应用设置修改偏好,通过系统设置管理麦克风权限,或删除应用及其本地数据。
7. 政策更新
如果应用的数据处理方式发生变化,本页面会更新日期并说明新的处理方式。涉及新数据收集或新权限时,将在功能启用前提供清楚说明,并按适用规则取得许可。
8. 联系开发者

Your practice audio stays on your device
GuitarTool Privacy Policy · Updated August 22, 2026
Zhichao Wei (the “developer”) respects your privacy. This policy explains how GuitarTool handles information across tuning, metronome practice, chord lookup, Home Screen widgets, and Apple Watch features.
1. Information we do not collect
GuitarTool does not collect, sell, or share personal information. The app requires no account or sign-in. It does not collect names, email addresses, phone numbers, precise location, contacts, photos, advertising identifiers, or usage analytics, and it contains no advertising, analytics, or third-party tracking SDKs.
2. Microphone and audio processing
The app requests microphone access only when you start the tuner. Microphone audio is used on your device to calculate pitch, cents, signal strength, and stability in real time.
- Audio is processed entirely on your device and is not sent to the developer or any third-party server.
- Microphone recordings are not saved to files, Photos, iCloud, or other persistent storage.
- Live capture stops and analysis buffers are released when you stop tuning, switch tools, or move the app to the background.
- You can revoke microphone access in iOS Settings at any time. Only the tuner will become unavailable.
3. Local settings and App Group sharing
The app stores settings such as tempo, time signature, practice presets, tuning presets, theme, and interface language on your device. Some metronome state is shared through an Apple App Group between GuitarTool and its Home Screen widget so the widget can display and control the same local configuration.
4. Network use, third parties, and tracking
GuitarTool's core features do not require an internet connection. The app includes no third-party advertising, analytics, or tracking services, creates no user profile, and performs no cross-app or cross-site tracking.
This privacy policy page does not load external fonts, analytics scripts, or tracking pixels and does not set cookies. The language control changes only the current page display and does not send a preference to a server.
5. Children's privacy
GuitarTool is not designed to collect information from children and does not knowingly collect personal information from children or other users. The app has no accounts, social features, or data-upload feature through which a child could submit profile information to the developer.
6. Security and your choices
Data minimization is the app's primary protection: audio is neither uploaded nor retained, and practice settings remain in storage provided by Apple platforms. You can change preferences in the app, manage microphone access in system settings, or delete the app and its local data.
7. Changes to this policy
If the app's data practices change, this page will show a revised date and describe the new handling. If a feature introduces new data collection or permissions, the app will explain them before the feature is enabled and request consent where required.
8. Contact the developer
