本政策适用于 GuitarTool Android（包名 com.guitar123.toolbox）及配套 Wear OS 应用。开发者：Qishan Labs。更新日期：2026 年 10 月 10 日。
调音器仅在用户开启调音、并授权麦克风后读取音频，音高计算在设备本地进行。应用不保存音频文件，不将录音发送到开发者服务器。退出调音页面或应用进入后台时，手机调音停止；Wear OS 在进入环境模式时暂停，恢复交互模式后可继续用户已开启的调音。相机权限仅用于闪光灯随节拍闪烁，不拍照或录像。通知权限用于后台节拍播放通知。相册保存功能在较新 Android 版本中仅写入用户选择保存的和弦图片；旧版本需要存储写入权限。拒绝权限后仍可使用不依赖该权限的功能。
主题选择、语言、节拍设置、练习预设、调音设置及购买凭证保存在本设备。自动评价时机仅使用本地的练习完成计数、练习日期、版本与请求时间，不上传练习活动。应用没有开发者账户、广告或分析 SDK。卸载应用会移除其本地应用数据；已导出到相册或主动分享的图片需由用户在对应应用中管理。
主题购买和恢复购买通过 Google Play Billing 完成。Google 根据其政策处理支付和购买信息，开发者应用验证签名购买凭证以判断主题使用权。应用可通过 Google Play 请求原生评价，是否展示由 Google 决定。配对的手机与手表通过 Google Wearable Data Layer 同步应用语言设置。应用不向开发者服务器上传音频、和弦或练习记录。Google 服务的数据处理受 Google 隐私政策约束。
分享和弦会将生成的图片交给用户选择的分享应用；分享应用链接同样由用户选择接收渠道。反馈功能打开邮件应用，只有用户主动发送后，开发者才会收到邮件内容和发件信息；请不要发送不必要的敏感信息。如需了解、删除主动发送的反馈信息，请联系 weizhichao1027@gmail.com。
本地设置和练习数据保留至你在应用内重置对应内容、清除应用数据或卸载应用。购买凭证可随恢复购买重新取得；清除本地数据不会删除 Google Play 的交易记录。主动发送的支持邮件仅用于处理请求、后续支持及适用的记录义务，并仅在这些目的所需期间保留；可通过上述邮箱申请访问、更正或删除。分享后的内容由你选择的平台按其规则管理。
公开隐私页面托管于 GitHub Pages。访问网页时，托管方可能处理 IP 地址、请求和浏览器信息以提供并保护网站，具体见 GitHub 隐私声明。本页面不嵌入广告、分析脚本、跟踪像素或第三方字体。应用内离线副本无需访问托管网站。
如未来功能或数据处理方式发生变化，我们将更新本政策，并在适用时提供提示或征得授权。
This policy covers GuitarTool Android (com.guitar123.toolbox) and its companion Wear OS app. Developer: Qishan Labs. Updated October 10, 2026.
The tuner processes microphone audio locally only after you start tuning and grant permission. The app does not save recordings or upload audio to the developer. Phone tuning stops when leaving the tuner or backgrounding the app. Wear OS pauses tuning in ambient mode and can resume an existing user request when interactive again. Camera permission controls only the metronome flashlight; no photos or video are captured. Notifications support background metronome playback. Saving a chord image writes the image you choose to save; older Android versions require storage permission.
Preferences, practice presets, tuning settings and signed purchase receipts remain on your device. Local practice completion counts, dates, app versions and review request times determine when a native review request may be made. No developer accounts, advertising SDKs or analytics SDKs are included. Uninstalling removes app data; images you export or share remain in the destination you choose.
Google Play Billing handles purchases and restoration. The app verifies signed receipts to determine theme access. Google controls billing and whether its native review prompt appears. Paired devices use Google Wearable Data Layer to synchronize the app language preference. Google's processing is governed by its privacy policy.
Sharing hands a generated image or app link to your chosen app. Feedback opens your email app; the developer receives your message and sender information only if you send it. To ask about or request deletion of feedback you sent, contact weizhichao1027@gmail.com. Support emails are used to handle your request, provide follow-up support and meet applicable record-keeping obligations, and retained only as needed for those purposes. You may request access, correction or deletion using that address.
Local settings and practice data remain until you reset the relevant content, clear app data or uninstall. Restoring purchases may retrieve receipts again; deleting local data does not delete Google Play transaction records. Content you share remains subject to your chosen destination’s controls.
The public policy page is hosted on GitHub Pages. The host may process IP addresses, requests and browser information to operate and protect the website, under the GitHub Privacy Statement. This page embeds no advertising, analytics scripts, tracking pixels or third-party fonts. The bundled offline policy does not contact the website.
We will update this policy if app functionality or data handling changes.
