隐私政策 / Privacy

01我们是谁

本政策说明 DriftGuide（以下简称「本应用」）如何处理与您设备相关的信息。 开发者为 DriftGuide 的发布者（Apple App Store 所列卖家信息为准）。

02我们收集什么

本应用以本地处理为主，默认不会把您的个人内容上传到我们的服务器。

• 偏好与会话记录：时长、语言、外观、所选环境声、引导完成情况、自愿评分等，保存在您的设备本地（如系统偏好存储）。
• 自定义环境声文件（可选）：若您导入音频，文件仅保存在本应用的设备沙盒目录中。
• 麦克风音量特征（可选「睡眠评分」）：仅在您开启并同意后使用。本应用分析实时音量水平以估计安静占比、疑似鼾声/梦话次数等聚合指标。不会录音，不会保存音频文件，也不会上传音频。
• 运动传感器（可选）：用于「面朝下结束引导」等功能，数据在设备本地瞬时使用，不上传。

03我们如何使用信息

• 提供入睡前引导、环境声播放与界面偏好；
• 在您开启时生成本地「睡眠评分」洞察；
• 改进产品稳定性（若您通过系统渠道向我们反馈崩溃信息，以 Apple 机制为准）。

04我们是否与第三方共享

我们不会出售您的个人数据。本应用当前不接入用于广告追踪的第三方分析 SDK。 若未来引入必要服务，我们将更新本政策并在适用法律要求时征得同意。

通过 Apple App Store / TestFlight 分发时，Apple 可能按其自身隐私政策处理购买、设备与诊断相关信息。请参阅 Apple 隐私政策。

05权限说明

• 麦克风：仅用于可选的睡眠评分音量分析；可在系统设置中随时关闭。
• 照片/文件/媒体库（若系统请求）：仅用于您主动导入环境声音频。
• 后台音频：用于引导或环境声在锁屏时继续播放。

06数据保存与删除

本地偏好与历史保存在您的设备上。卸载本应用通常会删除应用沙盒内数据。 您也可以在系统设置中撤销麦克风等权限。

07儿童隐私

本应用不以儿童为主要对象。若您是监护人并认为儿童向我们提供了信息，请通过下方方式联系我们。

08政策更新

我们可能不时更新本政策。更新后会在本页面修订「生效日期」。重大变更时，我们可能通过应用内提示等方式告知。

01Who we are

This Privacy Policy explains how DriftGuide (“the App”) handles information on your device. The publisher is the seller listed on the Apple App Store product page.

02What we collect

The App is designed for on-device processing and does not upload your personal content to our servers by default.

• Preferences & session history: duration, language, appearance, selected ambient sound, guide progress, optional ratings — stored locally on your device.
• Custom ambient audio (optional): if you import a sound file, it stays in the App’s local sandbox.
• Microphone level features (optional Sleep Score): used only when you enable the feature. The App analyzes live volume levels to estimate quiet ratio and possible snore/talk events. We do not record audio, save audio files, or upload audio.
• Motion sensors (optional): used for features such as face-down to finish the guide; processed on device and not uploaded.

03How we use information

• To provide the bedtime wind-down guide, ambient playback, and preferences;
• To generate an on-device Sleep Score insight when enabled;
• To improve stability if you send diagnostics through Apple’s channels.

04Sharing

We do not sell your personal data. The App does not currently include third-party advertising analytics SDKs. If that changes, we will update this policy and obtain consent where required.

Distribution via the App Store / TestFlight means Apple may process purchase, device, and diagnostic data under Apple’s Privacy Policy.

05Permissions

• Microphone: only for optional Sleep Score level analysis; you can revoke it in iOS Settings.
• Photos / files / media library (if prompted): only when you choose to import ambient audio.
• Background audio: so guidance or ambient sound can continue while the screen is locked.

06Retention & deletion

Local preferences and history remain on your device. Uninstalling the App typically removes its sandbox data. You may also revoke permissions in system settings.

07Children

The App is not directed at children. If you believe a child has provided information to us, please contact us.

08Changes

We may update this policy and will revise the effective date on this page. Material changes may be noted in the App.

09Contact

For privacy questions, use App Support on the App Store product page or the developer contact listed there. (Replace this with your real email before publishing, e.g. your-email@example.com.)
