Really interesting. But whether what Xiaomi browser does it's a spyware, what's is Google?

Does Google collects our navigation data? (Yes if we are using chrome or android and logged in)

Does Google knows what videos and what kind of videos do we watch? (Do you need an answer?)

Call it's a spyware because is a chinese company? Really? Nah. Google does the same or at least worst than it.

I'm neither defending Xiami nor Google. The question is: almost every application does data collection. And if you call it as spyware, therefore every app which does data collection is a spyware.
