本政策适用于 Matrix LED 移动应用(Android 与 iOS),以及链接到本政策的其他 LedBadge 系列应用(以下统称“本应用”)。我们尊重并保护你的隐私。本政策说明本应用会处理哪些信息、为什么处理、如何存储,以及你可以如何控制这些信息。
1. 我们是谁
本应用由深圳市乐闪光电子有限公司(品牌:Matrix LED / LedBadge)提供。联系邮箱:38211357@qq.com。
2. 本应用处理的信息
我们不要求你注册账号,也不会收集你的姓名、电话号码、通信录或精确位置。
2.1 蓝牙设备信息
当你扫描、连接或向 LED 设备发送内容时,本应用会读取附近蓝牙设备的名称、设备标识符、信号强度、广播数据和固件版本。这些信息只用于发现设备、建立连接、发送内容和检查固件更新,并保存在本机“最近设备”记录中,不会上传到我们的服务器。
2.2 你创建的内容
你在本应用中编辑的文字、点阵图案、图片、GIF、DIY 作品、显示设置和音乐频谱设置只在本机处理和保存,并通过蓝牙发送到你选择的 LED 设备。我们不会上传、备份或查看这些内容。当你使用 DIY 的相机、相册或 GIF 载入功能时,App 只会读取你主动选择的图片或 GIF,并在本机裁剪、缩放、转换为点阵;不会扫描、上传或收集你的相册内容。
2.3 麦克风
只有当你主动开启“音乐频谱/麦克风”功能时,本应用才会请求麦克风权限并读取实时音频电平。音频在你的设备上即时处理,我们不录音、不保存、不上传音频。
2.4 本地缓存
为了加快预览和再次打开,本应用会在应用私有目录保存预览图、字体与素材缓存、最近设备和设置。你可以通过系统“清除数据”或卸载应用删除这些内容。
2.5 固件更新请求
当你检查或下载 LED 设备固件时,本应用会访问 api.ledbadge.cn。该服务器可能记录常规访问日志(如 IP 地址、访问时间、请求的文件和 User-Agent),用于安全防护、故障排查和容量管理。我们不会将这些日志与你的身份关联。
2.6 DCloud 运行引擎
我们的产品基于 DCloud uni-app 开发。使用 DCloud uni-app 运行引擎的 LedBadge 系列应用,可能由该引擎为崩溃诊断、兼容性分析、安全目的和统计分析处理设备型号、操作系统版本、应用版本、IP 地址、设备标识信息(如 Android ID;在相关 SDK 启用时可能包括 OAID)和崩溃日志。相关处理受 DCloud 隐私政策约束。
3. 权限说明
- 蓝牙/附近设备:用于扫描、连接和向 LED 设备发送内容。
- 位置信息(仅 Android 11 及以下):Android 系统要求旧版本在扫描低功耗蓝牙设备时授予位置权限。本应用不读取、不保存、不上传你的实际位置。
- 麦克风:仅在你开启音乐频谱功能时使用,用于实时计算音频电平,不录音。
- 相机/照片/GIF:仅在你主动拍摄或选择图片/GIF 时使用,只读取你选择的文件,用于转换为 LED 点阵。
- 网络:用于检查或下载 LED 设备固件,以及加载必要的运行资源。
4. 信息共享
我们不出售、出租或交易你的个人信息。除以下情况外,我们不会向第三方提供你的信息:
- 为提供本应用功能而使用的服务提供商(如 DCloud 运行引擎、固件托管服务器),且仅限其提供服务所必需的范围;
- 法律法规要求,或为响应司法机关、监管机构的合法要求;
- 为保护用户、公众或我们的合法权益所必需。
5. 存储与保留
本应用没有账号系统,也不提供云同步。蓝牙记录、设置和本地缓存保存在你的设备上,直到你清除应用数据或卸载应用。服务器访问日志按运维和安全需要短期保留。
6. 数据安全
我们使用 HTTPS 保护与固件服务器的通信,并尽量减少数据收集。蓝牙通信由设备之间的加密或配对机制(如设备支持)保护。请妥善保管你的设备,并仅连接你信任的 LED 设备。
7. 儿童隐私
本应用不面向 13 岁以下儿童(欧洲经济区为 16 岁以下)。我们不会有意收集儿童的个人信息。如果你认为儿童向我们提供了个人信息,请联系我们删除。
8. 你的权利
你可以随时在系统设置中撤销蓝牙、位置或麦克风权限;可以通过“清除数据”或卸载应用删除本机数据;也可以通过下方邮箱联系我们,了解、更正或删除与你有关的信息。
9. 政策更新
我们可能因功能或法规变化更新本政策。更新后会修改生效日期,并在应用或商店页面提供最新版本。重大变更时,我们会以显著方式提示。
10. 联系我们
如对本政策有任何疑问、请求或投诉,请联系:38211357@qq.com。
This policy applies to the Matrix LED mobile application for Android and iOS, and to other LedBadge family apps that link to this policy (together, the “App”). We respect and protect your privacy. This policy explains what information the App processes, why, how it is stored, and how you can control it.
1. Who we are
The App is provided by Shenzhen Leshanguang Electronic Co., Ltd. (brand: Matrix LED / LedBadge). Contact: 38211357@qq.com.
2. Information the App processes
We do not require an account and do not collect your name, phone number, contacts, or precise location.
2.1 Bluetooth device information
When you scan for, connect to, or send content to an LED device, the App reads nearby Bluetooth device names, identifiers, signal strength, advertising data, and firmware version. This information is used only to discover devices, connect, send content, and check for firmware updates. It is stored locally in your “recent device” record and is not uploaded to our servers.
2.2 Content you create
Text, dot-matrix patterns, images, GIFs, DIY designs, display settings, and music-spectrum settings that you create in the App are processed and stored on your device only, and are sent to the LED device you select over Bluetooth. We do not upload, back up, or view this content. When you use the DIY camera, photo library, or GIF import features, the App reads only the image or GIF you explicitly select and crops, scales, and converts it to a dot-matrix pattern on your device. It does not scan, upload, or collect your photo library.
2.3 Microphone
The App requests microphone access and reads real-time audio levels only when you start the music-spectrum feature. Audio is processed on your device in real time. We do not record, store, or upload audio.
2.4 Local cache
To speed up previews and reopening, the App stores preview images, font and asset caches, the recent device, and settings in its private app directory. You can delete this data by clearing the App data in system settings or by uninstalling the App.
2.5 Firmware update requests
When you check for or download LED device firmware, the App contacts api.ledbadge.cn. The server may keep standard access logs (such as IP address, access time, requested file, and User-Agent) for security, troubleshooting, and capacity management. We do not associate these logs with your identity.
2.6 DCloud runtime
Our product is built with DCloud uni-app. LedBadge family apps built with the DCloud uni-app runtime may have that runtime process device model, OS version, app version, IP address, device identifiers (such as Android ID; OAID may be included when the relevant SDK is enabled), and crash logs for crash diagnostics, compatibility analysis, security, and analytics. That processing is governed by the DCloud privacy policy.
3. Permissions
- Bluetooth / Nearby devices: to scan for, connect to, and send content to LED devices.
- Location (Android 11 and below only): older Android versions require location permission to scan for Bluetooth Low Energy devices. The App does not read, store, or upload your actual location.
- Microphone: used only when you start the music-spectrum feature to calculate audio levels in real time. Audio is not recorded.
- Camera / Photos / GIF: used only when you choose to take or select an image or GIF to convert into an LED pattern. Only the file you select is read.
- Network: to check for or download LED device firmware and to load required runtime resources.
4. Sharing
We do not sell, rent, or trade your personal information. We do not provide your information to third parties except:
- to service providers used to deliver App functionality (such as the DCloud runtime and the firmware hosting server), only as necessary for their services;
- when required by law, or in response to a lawful request from a judicial or regulatory authority;
- when necessary to protect users, the public, or our legitimate rights and interests.
5. Storage and retention
The App has no account system and no cloud sync. Bluetooth records, settings, and local caches remain on your device until you clear the App data or uninstall the App. Server access logs are retained for a short period as needed for operations and security.
6. Security
We use HTTPS to protect communications with the firmware server and minimize data collection. Bluetooth communications are protected by the pairing or encryption mechanisms supported by your devices. Please keep your device secure and connect only to LED devices you trust.
7. Children
The App is not directed to children under 13 (under 16 in the European Economic Area). We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, please contact us so we can delete it.
8. Your rights
You can revoke Bluetooth, location, or microphone permissions in system settings at any time. You can delete local data by clearing the App data or uninstalling the App. You can also contact us to access, correct, or delete information about you.
9. Changes
We may update this policy when features or laws change. We will update the effective date and make the latest version available in the App or on the store listing. We will provide prominent notice of material changes.
10. Contact
For questions, requests, or complaints about this policy, contact: 38211357@qq.com.
