隐私设置与数据控制：加密存储
Ant Messenger 允许你隐藏手机号与用户 ID，并为应用设置应用锁。 Combined with end-to-end encryption, burn after reading, anti-screenshot and two-way deletion, these controls limit what others can see and how long messages remain.
本页汇总 Ant Messenger 公开的隐私控制项，以及「用户信息、通信内容、数据文件」三类数据在端到端加密与私有化部署下的处理方式。

隐藏身份标识
Ant Messenger states that you can 可隐藏手机号与用户 ID. This reduces the personal information exposed to other participants in a conversation, so people you chat with do not have to see your number or your account identifier.
为设备上的应用加锁
You can 为应用设置应用锁. This restricts who can open Ant Messenger on a device you own, which matters most when up to 5 台设备 are signed in to the same account with real-time chat synchronization.
控制消息留存时长
Ant Messenger 提供三项消息级控制：
- 阅后即焚 — support for instantly burning a message after it has been read.
- 防截屏 — protection that limits copying of conversation content through screenshots.
- 双向删除不留痕 — a message can be removed for both participants, not just on the device that issued the deletion.
Underlying all three, Ant Messenger adopts the 国际主流端到端加密方式 to ensure message security.
三类数据的自主可控
Ant Messenger supports 私有化部署与云托管, realizing that "user information, communication content, and data files" are completely autonomous and safe and controllable. Each category is handled explicitly:
用户信息
账号与身份数据，包括可对其他参与者隐藏的手机号与用户 ID。
通信内容
消息内容受端到端加密保护，并支持阅后即焚与双向删除。
数据文件
上传至云盘的文件，高强度加密且不限容量、不限时间。
Because Ant Messenger is an 开源聊天应用, the implementation behind these controls can be inspected: you can use and view the source code for free.
