小铭调音 / Access Tuner 隐私政策

更新日期：2026-09-08。联系：mkong.musician@gmail.com。

麦克风与音频

应用在前台调音时，经系统授权，使用 iPhone 麦克风分析乐器音高。音频缓冲区仅在本机内存中实时处理，不录制为文件、不保存、不上传至开发者服务器。离开前台会停止音频会话。可在 iOS 设置中撤销麦克风权限。

本地设置与诊断

音色、音量、语速、外观、静默调音偏好和用户确认的耳机标识保存在设备内。系统日志和应用的检测信息可能包含输入/输出类型、耳机名称、音频会话错误、音高、音量、可信度、回调计数及当前状态，不包含录制音频。没有自动上传诊断的功能，没有广告或第三方统计 SDK。

“分享检测信息”仅在您主动触发并选择接收方后，通过 iOS 分享界面发送诊断文字。发送前请检查内容，耳机的自定义名称可能包含个人信息。接收方和所选分享服务各自处理您发送的信息。

App Store 购买与试用

App Store 版通过 Apple StoreKit 提供免费三天试用、一次性永久解锁、恢复购买和官方优惠码兑换。应用在本机读取已验证的商品标识、交易时间、交易标识及退款/撤销状态，用于判断使用权限。试用开始于 Apple 验证的试用领取交易时间，持续 72 小时，不自动续费或扣款。

开发者不接收您的银行卡信息或 Apple 账户登录凭据。支付、交易及 Apple 为开发者提供的销售报表等由 Apple 按其条款处理。试用时间检查点按试用交易保存在本机钥匙串，以帮助防止系统时间回拨；它不用于广告、追踪或设备画像。朋友 Ad Hoc 测试版不要求购买。

支持与网站

主动发送支持邮件时，邮件地址、邮件内容及您附加的诊断会由邮件服务和支持收件人处理，用于回复及排查问题。不要发送密码或付款凭据。访问隐私和支持网站会产生网络请求，托管服务可能正常处理 IP 地址及访问日志。应用不在后台请求这些页面。

您的选择

可关闭麦克风授权、关闭语音引导、修改本机设置，并决定是否分享诊断或发送邮件。卸载应用会移除应用沙盒数据，但 iOS 钥匙串中的试用检查点可能保留；Apple 的交易记录由 Apple 管理，重新安装不会重新赠送同一已领取试用。可邮件联系支持咨询数据问题。

启动更新检查

应用启动时在后台请求适用分发渠道的版本元数据，用于获取版本、系统兼容要求、更新说明和下载入口。请求不包含麦克风音频、调音记录、诊断数据或设备 UDID。网络服务商可能处理 IP 地址等常规连接信息。有新版时显示可关闭提示，由你选择前往 App Store 或朋友下载页升级，应用不会自动下载安装包。没有新版或自动检查失败时不弹出提示。

Access Tuner Privacy Policy

Updated October 20, 2026. Contact: mkong.musician@gmail.com.

Microphone and audio

With system permission, Access Tuner analyzes instrument pitch using the iPhone microphone while tuning in the foreground. Audio buffers are processed temporarily in device memory. Audio is not recorded to files, retained, or uploaded to a developer server. Audio stops when the app leaves the foreground. Microphone permission can be revoked in iOS Settings.

Local settings and diagnostics

Tone, volume, speech rate, appearance, silent tuning preferences, and user-confirmed headphone identifiers are stored on the device. System logs and in-app diagnostics may contain audio input/output types, headphone names, session errors, pitch, level, confidence, callback counts, and current status. They do not contain recorded audio. There is no automatic diagnostic upload, advertising, or third-party analytics SDK.

Diagnostic text is shared only when you explicitly use Share Diagnostics and choose a destination in the iOS share sheet. Review it first: a custom headphone name may contain personal information. Your selected sharing service and recipient handle the information you send.

App Store purchases and trial

The App Store edition uses Apple StoreKit for the free three-day trial, one-time permanent unlock, purchase restoration, and official offer-code redemption. The app reads verified product identifiers, transaction dates and identifiers, and refund/revocation status locally to determine access. The trial lasts 72 hours from the verified trial-claim transaction. It does not renew or charge automatically.

The developer does not receive payment card information or Apple Account login credentials. Apple processes payments and transactions and provides developer sales reporting under its terms. A checkpoint keyed to the trial transaction is stored in the device Keychain to help detect clock rollback. It is not used for advertising, tracking, or profiling. The friend Ad Hoc edition does not require payment.

Update checks at launch

At launch, the app requests version metadata for its distribution channel, including compatibility requirements, release notes, and update links. These requests do not include microphone audio, tuning records, diagnostics, or device UDIDs. Network providers may process ordinary connection information such as IP addresses. An available update shows a dismissible prompt; you choose whether to open the App Store or the friend download page. The app does not automatically download or install app packages. No prompt is shown when no update is found or an automatic check fails.

Support and websites

If you choose to send support email, your email address, message, and any attached diagnostics are handled by email providers and the support recipient to respond and troubleshoot. Do not send passwords or payment credentials. Opening the privacy or support website makes network requests, and its hosting provider may process IP addresses and access logs. The app does not fetch these pages in the background.

Your choices

You may revoke microphone permission, disable spoken guidance, change local preferences, and choose whether to share diagnostics or email support. Uninstalling removes app-sandbox data; a trial checkpoint may remain in the iOS Keychain. Apple manages transaction history, and reinstalling does not restart a previously claimed trial. Contact support with privacy questions.
