彩幕 ChromaBoard 隐私政策
本隐私政策说明彩幕 ChromaBoard(以下简称“本应用”)如何处理信息。本应用用于在 iPhone 或 iPad 上显示滚动字幕、静止文字和彩色闪屏,并可通过附近设备进行多屏拼接联动。
1. 我们不收集的数据
本应用不要求注册账号,不包含第三方广告 SDK,不包含分析 SDK,不进行跨 App 或跨网站追踪。开发者不会收集、出售或共享你的个人信息。
2. 本地保存的数据
为了提供基础功能,本应用会在你的设备本地保存以下内容:
- 你输入过的显示文字历史;
- 你保存的自定义样式,例如文字、颜色、字体、速度、方向和闪屏效果;
- 用于多屏联动设备识别的随机设备标识。
这些数据保存在你的设备上,不会由开发者服务器收集。你可以通过删除应用来移除这些本地数据。
3. 本地网络与蓝牙
本应用的多屏拼接联动功能需要在附近设备之间建立直接的同步连接:
- 在 iOS 上,使用 Apple 的 MultipeerConnectivity 技术,通过本地网络、Bonjour 和蓝牙发现附近设备;
在联动过程中,设备之间可能会交换以下信息:
- 设备显示名称;
- 随机设备标识;
- 屏幕尺寸、拼接顺序和 viewport 信息;
- 当前显示样式、播放起点和同步时钟信息。
这些信息仅在参与联动的设备之间直接传输,用于拼接屏同步,不会经过或发送给开发者服务器。
4. 权限说明
- 本地网络 / Wi-Fi 权限:用于发现并连接同一局域网内的附近设备。
- 蓝牙权限:用于辅助发现附近设备并保持多屏同步。
如果拒绝这些权限,单机显示功能仍可使用,但多屏联动功能可能无法正常工作。
5. 第三方服务
本应用当前不集成第三方广告、统计分析或云同步服务。
6. 儿童隐私
本应用不面向儿童收集个人信息。如果你认为儿童向我们提供了个人信息,请通过下方联系方式与我们联系。
7. 政策更新
我们可能会根据功能变化或法律要求更新本隐私政策。更新后的版本会发布在本页面,并标注新的更新日期。

Privacy Policy
This Privacy Policy explains how ChromaBoard handles information. ChromaBoard is used to display scrolling text, static text, and color flash effects on an iPhone or iPad, including multi-device screen stitching with nearby devices.
1. Data We Do Not Collect
The app does not require an account, does not include third-party advertising SDKs, does not include analytics SDKs, and does not track you across apps or websites. The developer does not collect, sell, or share your personal information.
2. Data Stored Locally
To provide app features, ChromaBoard stores the following data locally on your device:
- Text display history entered by you;
- Custom styles you save, such as text, colors, fonts, speed, direction, and flash effects;
- A random device token used for multi-device synchronization.
This data stays on your device and is not collected by developer servers. You can remove it by deleting the app.
3. Local Network and Bluetooth
The multi-device stitching feature establishes a direct synchronization connection between nearby devices:
- On iOS, it uses Apple's MultipeerConnectivity framework to discover nearby devices over local network, Bonjour, and Bluetooth;
During synchronization, nearby devices may exchange device display names, random device tokens, screen sizes, layout information, style data, playback start time, and clock synchronization data. This information is transmitted only directly between the participating devices for synchronization and does not pass through or get sent to developer servers.
4. Permissions
- Local Network / Wi-Fi: used to discover and connect nearby devices on the same local network.
- Bluetooth: used to help discover nearby devices and maintain synchronization.
If these permissions are denied, single-device display features remain available, but multi-device synchronization may not work.
5. Third-Party Services
The app currently does not integrate third-party advertising, analytics, or cloud synchronization services.
6. Children's Privacy
The app does not knowingly collect personal information from children. If you believe a child has provided personal information to us, please contact us.
7. Changes
We may update this Privacy Policy as features or legal requirements change. Updates will be posted on this page with a new effective date.
