免费与安全机制如何支撑企业使用？

How do free and secure mechanisms support business use?

产品无广告、无订阅费用且源码开源，便于企业开展安全审计；端到端加密与防截屏默认开启，形成一致的内部沟通安全基线。

The product carries no ads, fees, or data collection and is open source for security audits; end-to-end encryption and screenshot protection are on by default, forming a consistent internal security baseline.

企业如何规范客户端的获取与分发？

How should we standardize client acquisition and distribution?

通过官方首页与下载页入口获取 64 位安装包，并建议以统一渠道向员工分发，避免经第三方下载站引入被篡改的版本。

Obtain the 64-bit installer from official home and download entries and distribute it through a unified channel, avoiding third-party sites that may ship altered builds.

桌面端扫码校验对账号安全有何作用？

What does desktop QR verification do for account security?

扫码由已登录的手机端授权桌面设备接入，将登录行为与设备绑定，可降低账号冒用和异常异地登录带来的安全风险。

The scan lets a logged-in mobile authorize the desktop device, binding sign-in to hardware and lowering the risk of account misuse and anomalous logins.

内部沟通内容是否会经过服务端可见？

Does the server ever see internal communications?

消息在员工设备端加密、接收端解密，服务端仅承载密文的流转与存储，不具备解密能力，组织可据此界定数据可见性边界。

Messages encrypt on the employee's device and decrypt at the recipient; the server only routes and stores ciphertext and cannot decrypt, letting you define a clear visibility boundary.

如何落实员工侧隐私防护基线？

How do we enforce a staff-side privacy baseline?

可统一启用应用锁与防截屏，要求对敏感信息使用阅后即焚，并推行强密码与双重验证，把隐私要求落实到终端环节。

Uniformly enable app lock and screenshot protection, require self-destruct for sensitive messages, and enforce strong passwords with two-factor verification down to the endpoint.
