In the process of signing up to use your app I was told to contact a another user of your app to help with the process finishing the process of signing up. I don't know of anybody else who uses your app especially in China! I'm sorry to say but that whole part there sent up a lot of red flags.! Especially in the end when they say well if you're having trouble just give them your phone number! I'm sorry but that is like the equivalent of giving somebody your social security number.
