极致安全敏感通讯常见问题
Maximum-Security Sensitive Messaging FAQ
围绕最高等级防护与敏感信息保护的安全场景答疑，帮你用好 Ant Messenger 的每一道加密防线。
Security-scenario answers around highest-level protection and sensitive data, helping you make full use of every encryption layer in Ant Messenger.
端到端加密意味着什么？
What does end-to-end encryption mean?
端到端加密意味着消息在发出前即被加密为密文，只有收件人的设备持有解密密钥。整个传输与存储过程都保持密文状态，服务器、运营商与任何中间环节都无法读取内容，是当前最顶级的通讯保密机制。
End-to-end encryption means a message is turned into ciphertext before it leaves your device, and only the recipient's device holds the decryption key. It stays ciphertext through transit and storage, so servers, carriers, and intermediaries can never read it — the highest-grade communication secrecy available.
服务器会留存我的消息吗？
Does the server retain my messages?
不会。Ant Messenger 采用零数据留存设计，服务器不保存任何聊天内容与元数据。敏感消息阅读后即被清除，后端无迹可寻，即便服务器被攻破，也拿不到任何可读的敏感信息。
No. Ant Messenger uses a zero-retention design — the server stores no chat content or metadata. Sensitive messages are purged after reading, leaving nothing behind, so even a breached server yields no readable sensitive data.
如何开启防截屏与阅后即焚？
How do I enable screenshot blocking and self-destruct?
在设置中开启防截屏后，系统会拦截并预警截屏与录屏行为；在任意敏感会话中开启阅后即焚，并为每条消息设定销毁时长，对方阅读后即自动销毁、双方记录同步清零。
Enable screenshot protection in settings to block and alert against captures and recording; in any sensitive chat turn on self-destruct and set a burn timer per message — it auto-destroys after reading and clears records on both ends.
如何隐藏指定会话？
How do I hide a specific conversation?
进入会话详情将目标会话移入隐秘专区，该会话即从主列表与通知中整体隐藏，只有通过二次验证（密码或生物识别）才能进入查看，旁人无法察觉其存在。
Move a target chat into the secret zone from its details — it disappears from the main list and notifications entirely, accessible only after second verification (password or biometrics), invisible to others.
为什么说源码开放更安全？
Why is open source considered more secure?
源码开放意味着加密实现与数据处理逻辑接受全球安全研究者的公开审计，任何暗藏的后门或漏洞都会被及时发现，从而将『信任』建立在可验证的代码之上，而非厂商单方承诺。
Open source means the encryption implementation and data-handling logic undergo public audit by security researchers worldwide, so hidden backdoors or flaws get caught early — trust rests on verifiable code, not on a vendor's promise.
