Wechat information retention is divided into the following categories:
1, the chat record of WeChat is stored on the mobile phone. If you don't change your mobile phone and clean up your chat history, then the data will always be saved.
2. If the local chat record is cleared, you can't view the previous chat record.
3. After WeChat is uninstalled, the chat record will be deleted. If reinstalled, the previous chat history will not be displayed. If WeChat is updated, it will overwrite the previous version, and the chat record will still be saved on the mobile phone WeChat.
In addition, the information can be recovered by installing Tiandun WeChat chat record recovery software.
Extended data:
In response to WeChat information security issues, WeChat said:
First, WeChat does not keep any user's chat records, and the chat content is only stored on the user's mobile phone, computer and other terminal devices.
Second, WeChat will not use any chat content of users for big data analysis.
Third, the rumor that "we read your WeChat every day" is purely misunderstood because of the technical mode that WeChat does not store and analyze users' chat content.
