隐私政策
语音识别
Songlet 的语音识别在你的设备上离线运行，不需要联网。你的录音和识别出的逐字稿都保存在设备本地，不会上传到任何服务器。
AI 教练（可选）
只有在你于 App 内明确同意之后，Songlet 才会使用 Apple 智能（设备端模型或 Apple 的私密云计算）来帮你生成表达报告。你可以随时在「设置」中撤回这项同意。开发者不会收到这些对话或报告的内容——它们只在 Apple 的系统和你的设备之间处理。
内测统计
App 仅在设备本地记录行为次数与时长（例如开始过几次练习、每次用了多久），不含逐字稿、录音或题目内容。这些数字只保存在你的设备上，不会自动发送出去。只有当你自己在设置里点击「拷贝统计摘要」时，它们才会被复制到剪贴板，由你决定发给谁。
反馈
当你通过「设置 → 反馈与支持 → 发送反馈」提交反馈时，会发送以下内容：
- 你选择的类别（问题 / 建议 / 其他）和你填写的反馈内容；
- 你自愿填写的联系邮箱（可以不填）；
- 只有在你打开「附上 App 与系统版本」时，才会附带 App 版本号与系统版本号；
- 一个随机生成、不与你的 Apple 账号或身份绑定的安装 ID；
- 你发送反馈时所用的渠道（本机调试 / TestFlight / App Store）。
Apple 用来证明这份反馈确实来自一次正版安装的验证凭据（AppTransaction）只在服务器上校验一次，校验完成后不会被保存。
反馈保存在 Cloudflare 的 D1 数据库中，用于阅读、回复和改进 App。我们会将反馈保留到不再需要用它来回复你或改进产品为止；如果你想让我们删除某一条反馈，可以再次通过应用内反馈说明「请删除 #收据编号 这条反馈」，我们会据此处理。
Cloudflare 与 IP 地址
这个网站和反馈服务由 Cloudflare 提供网络加速与安全防护，Cloudflare 会按其自身的服务条款处理访问请求中的 IP 地址（例如用于防护恶意流量）。Songlet 的服务器代码本身不会把你的 IP 地址写入反馈记录或任何数据库。
广告与跟踪
Songlet 没有广告，不做用户跟踪，也不使用任何第三方分析 SDK。

Speech recognition
Songlet's speech recognition runs entirely on your device, offline. Your recordings and the transcripts it produces are stored locally on the device and are never uploaded to any server.
The AI coach (optional)
Only after you explicitly agree inside the app does Songlet use Apple Intelligence — the on-device model or Apple's Private Cloud Compute — to help write your expression report. You can withdraw that agreement at any time in Settings. The developer never receives the content of those conversations or reports; it is processed only between Apple's systems and your device.
Beta usage counters
The app keeps a few simple usage counters and durations on your device (for example, how many times you've started a rehearsal, and how long each one took) — no transcripts, recordings, or question content. These numbers stay on your device and are never sent anywhere automatically. They're copied to your clipboard only when you tap "Copy Stats Summary" in Settings yourself, and it's up to you what you do with them after that.
Feedback
When you send feedback through Settings → Feedback & Support → Send Feedback, this is sent:
- the category you chose (bug / suggestion / other) and the message you wrote;
- a contact email address, only if you choose to add one;
- the app version and OS version, only if you turn on "Include app and system versions";
- a randomly generated install ID that is not tied to your Apple account or identity;
- the channel you sent it from (local debug build, TestFlight, or the App Store).
The Apple-issued proof that the feedback came from a genuine install (an AppTransaction) is checked once on the server and is not kept afterwards.
Feedback is stored in a Cloudflare D1 database so we can read it, reply, and use it to improve the app. We keep it for as long as we need it to respond to you and improve the app. If you'd like a piece of feedback deleted, send another message through the same in-app feedback flow quoting its receipt number (the "#N" you were shown), and we'll act on it.
Cloudflare and IP addresses
This site and the feedback service run on Cloudflare, which handles the IP addresses in incoming requests under its own terms — for example, to protect the service from abusive traffic. Songlet's own server code does not write your IP address into any feedback record or database.
Ads and tracking
Songlet has no ads, does not track you, and uses no third-party analytics SDK.
