China's WeChat Denies Storing User Chats (reuters.com)
WeChat, China's most popular messenger app, on Tuesday denied storing users' chat histories, after a top businessman was quoted in media reports as saying he believed Tencent was monitoring everyone's account. From a report: "
WeChat does not store any users' chat history. That is only stored in users' mobiles, computers and other terminals," WeChat said in a post on the social media platform. "WeChat will not use any content from user chats for big data analysis. Because of WeChat's technical model that does not store or analyse user chats, the rumour that 'we are watching your WeChat everyday' is pure misunderstanding." More than 900 million people use WeChat.
There is another thing people forget. Chinese companies have to have government officials from their military and intel branches on their boards of directors. Similar, where Chinese ventures with foreign companies have to be 51% owned by China (and this are actively controlled by their government), having chats "accidentally" log is not surprising. At least in the US or Europe, if you want something made on their soil, you don't have to have an officer from MI5 or the CIA actively vote and decide what happens as a company.
