DeepSeek sends all user conversations to servers in China. Multiple governments and companies have already banned it — Italy banned it entirely, the US Navy banned its use on government devices, and several major corporations have blocked employee access. Supporters argue that all AI companies collect data and that DeepSeek's open-source model can be self-hosted with complete privacy. Critics argue that Chinese law requires companies to hand data to the government on demand. Is DeepSeek safe to use or is it a genuine privacy risk?
