+# CrossDesk Privacy Policy
+
+Last updated: August 8, 2026
+
+[中文](#中文) | [English](#english)
+
+## 中文
+
+### 适用范围
+
+本隐私政策适用于 CrossDesk 桌面客户端及项目提供的默认网络服务。用户自行部署或指定的服务器由相应服务器运营者负责，其数据处理方式不在本政策控制范围内。
+
+### 网络通信
+
+CrossDesk 是远程桌面软件，需要通过网络完成设备发现、连接协商及远程会话。客户端可能进行以下网络通信：
+
+- **默认服务：** 未启用自托管时，客户端会连接预配置的 CrossDesk 服务（`api.crossdesk.cn`），用于设备注册、信令、网络地址转换（NAT）穿透，并在无法建立直接连接时提供中继。
+- **版本检查：** 客户端启动时会从 CrossDesk 版本服务（`version.crossdesk.cn`）获取最新版本信息。当前即使启用自托管，版本检查仍会访问 CrossDesk 版本服务。
+- **远程会话：** 用户主动发起或接受远程连接后，CrossDesk 会根据使用的功能在设备之间传输屏幕画面、音频、键盘和鼠标输入、剪贴板文本以及用户选择传输的文件。剪贴板文本可能在远程会话期间自动同步。这些数据可能通过直接连接传输，也可能在必要时通过配置的中继服务器转发。
+- **自托管：** 用户可以在设置中指定自己的信令及中继服务器。自托管服务器的日志、数据保存和访问规则由其运营者决定。
+
+### 处理的信息
+
+为提供上述功能，CrossDesk 可能处理：
+
+- 连接所需的设备标识及认证信息；
+- IP 地址、端口、连接时间、连接状态等必要的网络元数据；
+- 版本检查请求产生的标准网络请求信息；
+- 用户授权的远程会话中处理的屏幕、音频、控制指令、剪贴板及文件内容。
+
+### 信息的使用与保存
+
+- 设备标识、连接设置及用户偏好会保存在本地设备上，以便后续使用。
+- 通过官方信令和中继服务处理的信息仅用于建立、维持和转发 CrossDesk 连接，以及服务运行、安全防护和故障排查。
+- 中继传输的远程会话内容仅用于实时转发，不用于广告或用户画像。
+- CrossDesk 桌面客户端不包含广告功能，也不会主动上传诊断日志、崩溃报告或用户行为分析数据。
+- 自托管服务器可能保存的日志和数据由其运营者控制，请向相应运营者了解其隐私与保存政策。
+
+### 用户选择
+
+用户可以：
+
+- 配置自托管服务器，以替代默认信令和中继服务；
+- 决定是否发起或接受远程会话；
+- 决定是否选择并传输文件；
+- 结束远程会话，以停止会话数据传输；
+- 删除 CrossDesk 的本地配置、缓存及日志文件。
+
+### 政策更新与联系方式
+
+本政策可能随着 CrossDesk 功能或网络服务的变化而更新。更新内容将在本文件中发布。如有隐私相关问题，请联系 [junkun.di@hotmail.com](mailto:junkun.di@hotmail.com)。
+
+---
+
+## English
+
+### Scope
+
+This Privacy Policy applies to the CrossDesk desktop client and the default network services provided by the project. Servers deployed or selected by users are operated by their respective administrators, and their data-processing practices are outside the control of this policy.
+
+### Network communications
+
+CrossDesk is remote desktop software and requires network communications for device discovery, connection negotiation, and remote sessions. The client may perform the following communications:
+
+- **Default services:** Unless self-hosting is enabled, the client connects to preconfigured CrossDesk services (`api.crossdesk.cn`) for device registration, signaling, network address translation (NAT) traversal, and relay when a direct connection cannot be established.
+- **Update checks:** On startup, the client retrieves current release information from the CrossDesk version service (`version.crossdesk.cn`). Update checks currently continue to use the CrossDesk version service even when self-hosting is enabled.
+- **Remote sessions:** After a user initiates or accepts a remote connection, CrossDesk transmits the data required by enabled features between devices. This may include screen content, audio, keyboard and mouse input, clipboard text, and files selected by the user. Clipboard text may be synchronized automatically during a remote session. Data may travel over a direct connection or through the configured relay server when necessary.
+- **Self-hosting:** Users may configure their own signaling and relay servers. Logging, retention, and access policies for a self-hosted server are determined by its operator.
+
+### Information processed
+
+To provide these functions, CrossDesk may process:
+
+- device identifiers and authentication information required for connections;
+- necessary network metadata, such as IP addresses, ports, connection times, and connection status;
+- standard network request information generated by update checks; and
+- screen, audio, control, clipboard, and file content processed during a remote session authorized by the user.
+
+### Use and storage of information
+
+- Device identifiers, connection settings, and user preferences are stored locally for subsequent use.
+- Information processed by the official signaling and relay services is used only to establish, maintain, and relay CrossDesk connections and for service operation, security, and troubleshooting.
+- Remote-session content passing through a relay is used only for real-time forwarding and is not used for advertising or user profiling.
+- The CrossDesk desktop client does not contain advertising functionality and does not intentionally upload diagnostic logs, crash reports, or behavioral analytics.
+- Logs and data that may be retained by self-hosted servers are controlled by their operators. Contact the relevant operator for its privacy and retention practices.
+
+### User choices
+
+Users may:
+
+- configure a self-hosted server instead of the default signaling and relay services;
+- choose whether to initiate or accept a remote session;
+- choose whether to select and transfer files;
+- end a remote session to stop session-data transmission; and
+- remove local CrossDesk configuration, cache, and log files.
+
+### Changes and contact
+
+This policy may be updated as CrossDesk features or network services change. Updates will be published in this file. For privacy-related questions, contact [junkun.di@hotmail.com](mailto:junkun.di@hotmail.com).

 ## 简介

 CrossDesk 是一个轻量级的跨平台远程桌面软件，支持 Web 端控制远程设备。

 CrossDesk 是 [MiniRTC](https://github.com/kunkundi/minirtc.git) 实时音视频传输库的实验性应用。MiniRTC 是一个轻量级的跨平台实时音视频传输库。它具有网络透传（[RFC5245](https://datatracker.ietf.org/doc/html/rfc5245)），视频软硬编解码（H264/AV1），音频编解码（[Opus](https://github.com/xiph/opus)），信令交互，网络拥塞控制，传输加密（[SRTP](https://tools.ietf.org/html/rfc3711)）等基础能力。

 如果是手动编译或手动部署 Windows 版本，请确保 `CrossDesk.exe`、`crossdesk_service.exe` 和 `crossdesk_session_helper.exe` 位于同一目录。安装或卸载服务需要使用管理员权限打开 PowerShell：
-```

+## Introduction

 CrossDesk is a lightweight cross-platform remote desktop software.

 CrossDesk is an experimental application of [MiniRTC](https://github.com/kunkundi/minirtc.git), a lightweight cross-platform real-time audio and video transmission library. MiniRTC provides fundamental capabilities including network traversal ([RFC5245](https://datatracker.ietf.org/doc/html/rfc5245)), video software/hardware encoding and decoding (H264/AV1), audio encoding/decoding ([Opus](https://github.com/xiph/opus)), signaling interaction, network congestion control, and transmission encryption ([SRTP](https://tools.ietf.org/html/rfc3711)).

 CrossDesk provides a local helper service on Windows named **CrossDesk Service**. Its service name is `CrossDeskService`. The service improves remote control in protected Windows states such as the lock screen, sign-in UI, credential UI, and secure desktop. It provides:
+
 - Remote status reporting for lock screen, sign-in, credential, and secure desktop states.
 - Remote `Ctrl+Alt+Del` (SAS) delivery.
 - Keyboard and mouse input forwarding while the remote Windows device is on the lock screen, sign-in UI, or secure desktop.

When the CrossDesk client starts, it tries to start the installed service automatically. When no CrossDesk client process is running on the machine, the service exits automatically. Uninstalling the client also stops and removes the service.

 - **The server must open the following ports: COTURN_PORT/udp, COTURN_PORT/tcp, MIN_PORT–MAX_PORT/udp, and CROSSDESK_SERVER_PORT/tcp.**
 - If you don’t mount volumes, all data will be lost when the container is removed.
- Certificate files will be automatically generated on first startup and persisted to the host at `/var/lib/crossdesk/certs`.As the default certificates are self-signed and cannot guarantee security, it is strongly recommended to apply for a trusted certificate from a cloud provider, deploy it to this directory, and restart the service.
+- Certificate files will be automatically generated on first startup and persisted to the host at `/var/lib/crossdesk/certs`. As the default certificates are self-signed and cannot guarantee security, it is strongly recommended to apply for a trusted certificate from a cloud provider, deploy it to this directory, and restart the service.
 - The database file will be automatically created and stored at `/var/lib/crossdesk/db/crossdesk-server.db`.
 - Log files will be created and stored at `/var/log/crossdesk/`.

-**Permission Notice**
-If the directories automatically created by Docker belong to root and have insufficient write permissions, the container user may not be able to write to them. This can cause:
-  - Certificate generation failure, leading to startup script errors and container exit.
-  - Database directory creation failure, causing the program to throw exceptions and crash.
