HONG KONG - WeChat, China&39;s most popular messenger app, on Tuesday denied storing users&39; chat histories, after a top businessman was quoted in media reports as saying he believed the app&39;s developer, Tencent Holdings, was monitoring everyone&39;s account.
"WeChat does not store any users&39; chat history. That is only stored in users&39; 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&39;s technical model that does not store or analyse user chats, the rumour that &39;we are watching your WeChat everyday&39; is pure misunderstanding."
Li Shufu, chairman of Geely Holdings, owner of the Volvo car brand, was quoted in Chinese media on Monday as saying Tencent Chairman Ma Huateng "must be watching all our WeChats every day".
WeChat did not immediately respond to a request for further comment.
According to a report by Amnesty International, Tencent ranked at the bottom of 11 tech firms running the world&39;s most popular messenger apps for how they use encryption to protect user privacy.
China&39;s cyber watchdog in September announced a new rule making chat group administrators and companies accountable for breaches of content rules.
In the same month, it handed down maximum penalties to tech firms including Tencent, Baidu and Weibo for failing to properly censor online content, and asked them to increase content auditing measures.
