1. How to Request Account & Data Deletion 一、如何申请删除账号及数据

We offer two methods to delete your account: directly through the WINChat application (instant self-service), or by submitting a manual request via email (available even if you have uninstalled the app or lost device access). 我们提供两种账号注销与数据删除途径：通过 WINChat 客户端内自主注销（即时生效），或者通过官方支持邮箱提交人工删除申请（即便您已卸载 App 或无法登录依然可用）。

Action is Irreversible: 操作不可撤销： Once account deletion is finalized, your account cannot be recovered. All unexported chats and personal content will be lost permanently. 注销申请处理完毕后将无法恢复，所有未备份的聊天记录及个人数据将永久清除。

Frequently Asked Questions 常见问题解答

Yes. Once the deletion process is complete, the associated mobile number or email address is unlinked from the old account, allowing you to register a fresh account if you wish to return.

可以。注销完全生效后，原绑定的手机号或邮箱即已解除占用，您可以重新注册一个全新的 WINChat 账号。

Your messages are removed from our active messaging servers and your local database. However, messages that recipients have already downloaded onto their private devices remain on their local device cache as part of their personal conversation copy.

您的消息将从服务器及您的设备端彻底清除。但是，对方用户设备上已经接收并缓存的历史消息属于对方的本地聊天副本，不能直接篡改对方本地缓存。

If requested in-app, deletion takes effect immediately and you are logged out. If requested by email, our support team will reply to your ticket within 3-7 business days confirming complete account purge.

如果是 App 内操作，确认注销后会立即退出并失效。如果是邮件申请，支持团队将在 3~7 个工作日内完成处理并向您的发件邮箱发送处理结果确认。
