不收集任何数据。本应用没有注册、没有登录、没有云端账号，不会向任何服务器上传您的 设备标识、使用记录、崩溃日志或屏幕内容。本政策下方的表格逐项列出了「哪些看似涉及数据的能力， 在本机是如何被限制的」，目的是让您清楚每一项权限的实际作用范围。
| 能力 | 实际用途 | 数据去向 |
|---|---|---|
| 屏幕画面采集 | 由您在系统广播选择器中主动启动，用于实时计算屏幕边缘的主色调 | 仅在本机内存中处理。不上传、不落盘、不保存截图，退出同步即释放 |
| 局域网通信 | 发现并控制您家中的 WLED 灯带设备（Bonjour 服务类型 _wled._tcp 与 _http._tcp） |
仅在您的局域网内以 HTTP / UDP 传输；不经过任何云端服务器 |
| 本机设置存储 | 保存界面偏好、灯带配置（设备地址、LED 数量、亮度等） | 仅存于本机；灯带配置通过 App Group 在主应用与广播扩展之间共享 |
| 诊断日志 | 记录同步状态，便于您自行排查问题 | 仅存于本机，不外发 |
| 外链打开 | 您在设置页主动点击「隐私政策」「查阅备案信息」时 | 由系统浏览器打开对应网页，本应用不读取其内容 |
明确不收集：姓名、手机号、邮箱、通讯录、相册、精确或粗略位置、麦克风音频、 相机画面、短信、剪贴板、IMEI、MAC 地址、IDFA、广告标识符、账号密码、支付信息。
用于发现并控制您家中的 WLED 灯带。本应用只在局域网内与灯带设备通信。由于灯带固件 不支持 TLS，局域网内使用 HTTP / UDP 明文协议，请您确保家庭 Wi-Fi 是可信网络。
iOS 要求跨应用读取屏幕颜色必须使用系统提供的「屏幕广播」机制，并会弹出系统授权提示， 该提示无法由应用跳过或隐藏。您随时可以下拉控制中心停止广播。停止后本应用不再接收任何屏幕帧。
无。本应用只使用 Apple 官方框架（SwiftUI、ReplayKit / Broadcast Upload、 Network、Foundation 等），未集成任何第三方 SDK，因而也没有第三方广告、统计、崩溃分析或 社交登录组件。这也是本应用在 App Store 的「App 隐私」中申报为 「未收集数据」的原因。
本应用是环境光工具，不面向不满十四周岁的儿童，也不会有意收集儿童的个人信息。 如监护人认为儿童在使用本应用，可随时卸载；本应用因不收集数据，卸载后不残留任何个人信息。
本政策如有更新，我们会在本页面发布新版本并更新「生效日期」。若变更涉及数据实践的重大调整， 我们会通过应用内提示告知。

None. There is no sign-up, no login and no cloud account. The app never uploads device identifiers, usage records, crash logs or screen content. The table below explains how each capability that could look like data collection is actually confined to your device.
| Capability | What it is used for | Where the data goes |
|---|---|---|
| Screen capture | Started by you in Apple's broadcast picker, to derive the dominant edge colours of the screen | Processed in on-device memory only. Never uploaded, never written to disk, no screenshots kept; released when you stop syncing |
| Local network | Discover and control your WLED strip (Bonjour services _wled._tcp and _http._tcp) |
HTTP / UDP inside your own LAN only; never routed through a cloud server |
| On-device settings | UI preferences and strip configuration (host, LED count, brightness) | On device only; strip config is shared between the app and the broadcast extension via an App Group |
| Diagnostic log | Records sync state so you can troubleshoot yourself | On device only; never transmitted |
| Outbound links | Only when you tap “Privacy Policy” or “Filing Lookup” in Settings | Opened in the system browser; the app does not read their content |
We explicitly do not collect: name, phone number, email, contacts, photos, precise or coarse location, microphone audio, camera, messages, clipboard, IMEI, MAC address, IDFA or any advertising identifier, credentials or payment information.
Local Network — needed to find and control your WLED strip. Because the strip firmware does not support TLS, LAN traffic uses cleartext HTTP / UDP; please keep your Wi-Fi trustworthy.
Screen recording (system broadcast) — iOS requires the system broadcast mechanism (and its non-dismissable consent prompt) for any app to read on-screen colours. You can stop the broadcast from Control Centre at any time; after that no frames reach the app.
What we do not do — no camera, microphone, photos, contacts or location permission; no “Allow tracking” request, because we do not track; no background network requests.
None. The app uses only Apple frameworks (SwiftUI, ReplayKit / Broadcast Upload, Network, Foundation). No advertising, analytics, crash-reporting or social-login SDK is bundled — which is why the App Store “App Privacy” declaration is “Data Not Collected”.
We store no personal data, so there is nothing to share or sell. All configuration and logs live on your device and are removed when you delete the app.
This is an ambient-lighting utility not directed to children under 14, and we do not knowingly collect any information from children.
You can revoke Local Network access, stop the screen broadcast from Control Centre, clear the app's local data, or simply delete the app. We hold no cloud copy of your data, so there is nothing to request for deletion.
