隐私政策：最高等级数据保护
Privacy Policy: Highest-Level Data Protection
Ant Messenger 极致安全敏感通讯版以最高等级防护为核心，本政策说明我们如何以零数据留存与密文存储守护你的每一次高隐私敏感通讯。
The Maximum-Security edition of Ant Messenger is built around highest-level protection. This policy explains how zero data retention and ciphertext storage guard every high-privacy sensitive conversation.
1. 零数据留存承诺
1. Zero Data Retention Commitment
Ant Messenger 坚持最高等级的零数据留存承诺：服务器不保存你的聊天内容、语音、图片、文件与任何元数据。敏感消息在完成投递并阅读后即被清除，后端不留任何可追溯的残留痕迹。
Ant Messenger upholds the highest-grade zero-retention commitment: our servers store no chat content, voice, images, files, or metadata. Sensitive messages are purged after delivery and reading, leaving no traceable residue behind.
2. 军规级端到端加密与密文存储
2. Military-Grade E2E Encryption & Ciphertext Storage
聊天消息、语音通话与敏感文件传输全程采用军规级端到端加密：内容在发送端加密、接收端解密，密钥仅存在于两端设备。即使数据以密文形式短暂经手系统，也始终处于不可解读的加密状态，服务器与任何第三方均无法破解。
Chats, voice calls, and sensitive file transfers are fully protected by military-grade end-to-end encryption: encrypted at the sender and decrypted at the recipient, with keys existing only on both devices. Even when data briefly passes through systems as ciphertext, it stays unreadable — servers and third parties can never break it.
3. 敏感信息的本地防护
3. On-Device Sensitive Data Protection
敏感信息在设备端同样受到最高等级防护：应用双重锁叠加生物识别形成门禁，防截屏拦截画面泄露，敏感会话可整体隐藏进入隐秘专区，重要文件支持深度粉碎删除，层层设防杜绝敏感数据被偷看或恢复。
Sensitive data is equally protected on device: dual app lock plus biometrics form the gate, screenshot blocking stops visual leaks, sensitive chats can be fully hidden in a secret zone, and important files support deep shredding — layered defenses keep sensitive data from being seen or recovered.
4. 不收集、不分享敏感数据
4. No Sensitive Data Collection or Sharing
我们承诺不向任何第三方出售、出租或提供你的个人信息与通讯内容，也不会因广告或商业利益共享数据。收集的有限信息仅用于保障服务安全运行与账号防入侵，绝不用于分析、画像或牟利。
We never sell, rent, or hand over your personal data or communication content to third parties, and we never share data for advertising or commercial gain. The limited information collected serves only service security and account anti-intrusion — never profiling, targeting, or profit.
5. 你的数据控制权与删除
5. Your Data Control & Deletion
你拥有对敏感数据的完全控制权：可随时双向删除聊天记录、使用阅后即焚销毁单条消息、以敏感文件粉碎覆写底层数据，或整体清空账号数据。结合零数据留存，删除后的内容与痕迹均不可恢复。
You have full control over your sensitive data: mutually delete chat records anytime, destroy individual messages with self-destruct, overwrite underlying data with file shredding, or clear all account data. Combined with zero retention, deleted content and traces are unrecoverable.
