I live in the US and recently got accepted to a position in China. I have been asked to download WeChat. I have some concerns with how transparent the data stored on my phone is if I were to download it, this is mostly picked up from news tidbits of news here and there over the past few years. I guess my main concerns are whether the files on my phone, passwords, emails, etc, and phone calls, voice mails, contacts, reddit posts, etc could potentially be seen by some, err, third party? Or am I just being super paranoid?
