免费又安全，靠谱吗？

Free and secure — can I trust it?

放心，免费是因为不靠卖你的数据赚钱：源码开源、无广告、无订阅，端到端加密和防截屏都是内置功能，装上就能长期用。

Yes — it's free because it doesn't profit from your data: the code is open, there are no ads or subscriptions, and end-to-end encryption with screenshot blocking is built in for long-term peace of mind.

Windows 版去哪儿下载不踩坑？

Where can I download the Windows version safely?

认准官网首页或下载页的入口获取 64 位安装包；别去来路不明的第三方下载站，那里最容易混进被改动过的版本。

Use the official entry on the homepage or download page to get the 64-bit installer; skip shady third-party sites where tampered builds hide.

电脑登录为啥非要先扫码？

Why must I scan a code to log in on the desktop?

这是让已经登录的手机给电脑授权，相当于多一道本人确认的关卡，能有效挡掉账号冒用和异地登录的风险。

It lets your logged-in phone authorize the computer, adding a you-are-you checkpoint that blocks account misuse and unexpected remote logins.

服务器能偷看我聊了啥吗？

Can the server peek at my chats?

看不到。消息在发出前就加密好了，传到服务器、存下来全是密文，解密钥匙只在收件人手里，服务器没有解密的入口。

No. Messages are encrypted before they leave, so what the server transmits and stores is ciphertext; the decryption key stays with the recipient only.

还能怎么再保护一下隐私？

What else can I do for privacy?

把应用锁和防截屏打开，聊敏感内容时用阅后即焚，密码设得强一点再开双重验证，层层保险更踏实。

Turn on app lock and screenshot blocking, use self-destruct for sensitive topics, pick a strong password, and enable two-factor verification for extra peace of mind.
