隐私政策

Privacy Policy

最后更新：2026 年 6 月

Ant Messenger 致力于用端到端加密保护你的每一次对话。本政策说明我们如何（以及在多大程度上不）收集、使用与保护你的数据。我们坚持数据最小化原则，能不收集的绝不收集。

Ant Messenger is committed to protecting every conversation with end-to-end encryption. This policy explains what we do — and, more importantly, what we do not — collect, use and protect. We follow data-minimization by default.

我们收集的信息

Information We Collect

• 账户标识：注册所需的用户 ID；你可选择隐藏手机号，避免与个人身份强绑定。
• 设备信息：用于多设备登录与消息同步的必要令牌，不含聊天内容。
• 加密元数据：仅转发密文与路由所需的最小元数据，服务器无法读取消息正文、图片或文件。

• Account identifier: the user ID required to register. You may hide your phone number to avoid tight binding to your identity.
• Device information: tokens necessary for multi-device login and message sync — never message content.
• Encryption metadata: only the minimum metadata required to relay ciphertext and route traffic. Servers cannot read message bodies, images or files.

端到端加密与数据自主权

End-to-End Encryption & Data Ownership

所有聊天内容默认采用端到端加密，密钥仅存于你的设备。我们支持阅后即焚、防截屏与双向删除，让你完全掌控数据的生命周期。你还可选择私有化部署或专有云托管，密钥与数据完全由你掌握。

All chat content is end-to-end encrypted by default; keys live only on your devices. We support self-destruct messages, screenshot prevention and bidirectional deletion so you control your data's lifecycle. Choose private deployment or dedicated cloud hosting — keys and data stay yours.

我们不会出售你的数据

We Never Sell Your Data

我们不会向任何第三方出售、出租或交易你的个人数据，也不会用你的聊天内容用于广告定向。Ant Messenger 完全免费、开源可审计。

We never sell, rent or trade your personal data to any third party, and we never use your messages for advertising. Ant Messenger is free and open-source for audit.

开源审计

Open-Source Audit

客户端代码开源，任何安全研究者都可审查加密实现。我们定期邀请独立机构进行安全审计，并将结果公开。

Our client code is open source, so any security researcher can audit the encryption. We engage independent auditors regularly and publish the results.

• 开启应用锁、隐藏手机号与用户 ID；
• 对数据处理提出疑问或行使相关权利。
