我们做什么
发送猫用于在可信设备之间进行文本发送、手机输入直达电脑、电脑截图直传手机、剪贴板同步、图片和文件传输、设备关系管理、历史记录和提示词收集管理。产品优先服务个人多设备使用场景，让手机、电脑之间的输入和传输更直接。
SendCat helps trusted devices send text, input from phone to desktop, transfer desktop screenshots to phone, sync clipboard content, transfer images and files, manage device relationships, keep history, and organize prompt fragments. It is designed for personal multi-device workflows.
设备与连接
发送猫主要依赖同一局域网、个人热点或用户授权的网络环境发现设备。你可以将设备设置为“我的设备”“好友设备”或保持为陌生设备，并按需开启剪贴板、截图、图片和文件传输。
SendCat mainly discovers devices on the same local network, personal hotspot, or other user-authorized network environment. You can mark devices as My Devices, Friend Devices, or leave them as unknown devices, and enable clipboard, screenshot, image, or file transfer as needed.
安全原则
剪贴板、图片和文件传输会结合设备关系、配对密钥、设备 ID、会话 ID 和操作类型进行校验，并使用 AES-GCM 加密降低误传、窃听和篡改风险。你仍应只在可信网络和可信设备之间传输敏感内容。
Clipboard, image, and file transfers are checked with device relationships, pairing keys, device IDs, session IDs, and operation types, and are protected with AES-GCM encryption to reduce accidental delivery, eavesdropping, and tampering risks. You should still transfer sensitive content only on trusted networks and trusted devices.
