This FAQ accompanies the full report on privacy in the WeChat ecosystem.

We find that they collect more usage data than is disclosed in the WeChat privacy policy.

We discovered over 60,000 unique censorship rules used to partially or totally censor search results across eight China-accessible search platforms analyzed.

Health customs forms which transmit passport details, demographic information, and medical and travel history are also vulnerable. Server responses can also be spoofed, allowing an attacker to display fake instructions to users.
