Ant Messenger 隐私政策
Ant Messenger Privacy Policy
生效日期：2026年8月3日
Effective Date: August 3, 2026
一、我们如何保护你的云端数据
1. How We Protect Your Cloud Data
Ant Messenger 云端同步版以数据安全为核心。所有聊天记录、会话漫游与文件在进入云端前均经过端到端加密，云端仅保存密文。我们无法读取、导出或转售你的任何通讯内容，你的密钥始终掌握在自己手中。
Ant Messenger Cloud Sync places data security at its core. Every chat, roaming session, and file is end-to-end encrypted before entering the cloud, which stores only ciphertext. We cannot read, export, or resell any of your communications — your keys always remain in your hands.
二、云端密文存储与加密机制
2. Encrypted Cloud Storage & Encryption
云端存储采用高强度加密算法，数据在传输与静态存储两个环节均保持密文状态。无论是多端实时同步还是加密云备份，任何脱离你设备的数据都以密文形式存在，杜绝明文泄露风险。
Cloud storage uses strong encryption, keeping data as ciphertext both in transit and at rest. Whether syncing across devices or backing up to the cloud, any data leaving your device exists only as ciphertext, eliminating plaintext exposure risk.
三、我们收集的信息范围
3. What Information We Collect
为提供多端漫游与云同步服务，我们会处理必要的账号标识与设备信息，仅用于保障同步稳定性与安全验证。我们不会收集、分析或利用你的聊天内容，这些内容始终以密文形式存储且仅供你自己解密使用。
To provide multi-device roaming and cloud sync, we process only necessary account identifiers and device information, used solely for sync stability and security verification. We do not collect, analyze, or exploit your message content, which always remains encrypted and decryptable only by you.
四、你的数据主权与自主管理
4. Your Data Sovereignty & Self-management
你对自己的数据拥有完全主权：可随时查看、导出、删除云端备份，也可选择关闭云同步。企业用户更可将数据部署在自有服务器，通过私有云部署实现数据的完全自主管理。
You hold full sovereignty over your data: you can view, export, or delete cloud backups anytime and opt out of cloud sync. Business users can also deploy data on their own servers via private cloud deployment for complete self-management.
五、多端同步中的数据安全
5. Security in Multi-device Sync
跨设备无缝切换采用安全会话验证，新设备登录需经密钥授权。断点续传与文件云端中转过程全程加密，保证你在任何设备上的每一次同步都安全可信。
Cross-device switching uses secure session verification, and new devices require key authorization to sign in. Resumable transfers and cloud file relay are fully encrypted, keeping every sync on any device safe and trustworthy.
