Verdict: WeChat is one of the least private messaging apps available. Messages are not end-to-end encrypted, content is actively censored, and all data is accessible to Chinese authorities. Use only when absolutely necessary.
WeChat is China's dominant super-app combining messaging, social media, payments, and services for over 1.3 billion users. It is subject to Chinese government censorship and surveillance laws.
