1. Ephemeral Anonymous Sessions1. 匿名会话即时阅后即焚

Anonymous conversations store message history strictly in your browser's local memory. The server stores zero dialogue text for anonymous sessions.

在匿名体验模式下，对话记录仅保存在你的浏览器本地，服务端绝不持久化任何匿名对话正文。

2. Right to be Forgotten (True Hard Delete)2. 彻底被遗忘权 (真正物理硬删除)

Calling POST /api/auth/delete-account executes true SQL DELETE cascades across all user tables. No soft delete or cosmetic UI hiding.

调用数据抹除接口将执行真正的 SQL DELETE 级联删除，彻底抹除全部用户记录、记忆、对话与会话，绝不搞前端隐藏把戏。
