引擎模拟器 隐私政策
一句话总结：本 App 不收集任何个人信息，不联网，没有账号，也不含广告或统计分析 SDK。你的调校存档和恢复备份只保存在你自己的设备上。
1. 我们收集哪些信息
不收集。本 App 不收集、不记录、不上传任何个人信息或设备信息，包括但不限于：姓名、手机号、邮箱、位置、通讯录、照片、设备标识符（如 IDFA）、使用统计和崩溃日志。
2. 网络连接
本 App 没有任何联网功能，运行时不会连接互联网，也不会与任何服务器通信。断网（飞行模式）下所有功能都能正常使用。App 基于 Unity 引擎开发，引擎自带的数据统计、崩溃上报等云服务均已关闭。
3. 数据保存在哪里
- 你的调校、命名存档和设置（例如音量、画质）只保存在你自己的设备上：一部分保存在系统提供的 App 偏好设置里，一部分以文件形式保存在 App 的“文稿”文件夹中。
- 当你主动点“导出备份”时，App 会生成 JSON 备份文件；启动恢复机制也可能自动在本机保存调校草稿备份，以便启动失败后找回原有调校。这些文件都不会上传。你可以通过 App 的导入功能或系统“文件”App 管理它们，是否复制或分享由你决定。
- 我们（开发者）无法看到、也无法取得这些数据。删除 App 时，这些数据会随 App 一起从设备上删除。
4. 第三方服务
本 App 不含广告、统计分析、崩溃上报、社交分享、第三方登录或支付等任何第三方 SDK，没有账号系统，也没有内购。App 内的发动机声音素材来自公开授权（CC0 / CC BY 4.0）的录音，已打包在 App 内，播放时不需要联网；署名见 App 内“设置 › 关于与致谢”。
5. 跟踪
本 App 不会跟踪你，也不会把任何数据与其他公司的数据关联，不用于广告。
6. 系统权限
本 App 不申请相机、麦克风、定位、通讯录、相册、蓝牙、通知等任何系统权限。
7. 未成年人
本 App 适合所有年龄段使用。由于不收集任何个人信息，也就不会收集未成年人的个人信息。
8. 政策变更
如果将来的版本改变了以上做法，我们会先更新本页面并修改生效日期，再发布新版本。

Privacy Policy (English)
In short: the app collects no personal data, never connects to the internet, has no accounts and contains no advertising or analytics SDKs. Your saved tunes and recovery backups stay on your own device.
1. Information we collect
None. The app does not collect, log or upload any personal or device information — no name, phone number, e-mail, location, contacts, photos, device identifiers (such as the IDFA), usage analytics or crash logs.
2. Network access
The app has no online features. It never connects to the internet and never talks to any server; everything works in airplane mode. The app is built with the Unity engine; the engine’s analytics and crash-reporting cloud services are switched off.
3. Where your data is stored
- Your tunes, named saves and settings (e.g. volume, graphics quality) are stored only on your device: partly in the app’s system preferences storage and partly as files in the app’s Documents folder.
- Tapping “导出备份” (Export backup) creates a JSON backup. The startup recovery mechanism may also automatically save a local tuning-draft backup so your previous tuning can be recovered after a failed launch. These files are never uploaded. You can manage them through the app's import feature or the system Files app; copying or sharing them is your choice.
- We, the developer, cannot see or access this data. Deleting the app deletes it from your device.
4. Third-party services
The app contains no advertising, analytics, crash reporting, social, sign-in or payment SDKs, has no account system and no in-app purchases. The engine sounds come from openly licensed recordings (CC0 / CC BY 4.0) bundled with the app and play offline; attribution is shown in Settings › 关于与致谢 (About & Credits).
5. Tracking
The app does not track you and does not link any data with data from other companies or use it for advertising.
6. Permissions
The app requests no system permissions — no camera, microphone, location, contacts, photos, Bluetooth or notifications.
7. Children
The app is suitable for all ages. As it collects no personal data, it collects no data from children.
8. Changes
If a future version changes any of the above, this page will be updated (with a new effective date) before that version is released.
