Quite agree when you use Android, your personal data is at stake especially if you try to install any of their apps. The most common chat apps like WhatsApp compromises so much on user's privacy. But then many users are not that tech savvy that they understand whats going on in the background. Even in the facebook if you install on Android, there is lot of privacy infringement that user may not come to know about.
If you're going to use these devices (smart phones and apps), you pretty much have to resign yourself to giving up sovereignty over your personal data. It's rarely clear, even to experienced users, who's getting access to what and what will be done with it.
I have on occasion decided against using an app I wanted because the data access seemed too onerous, but that's the exception.
I am not sure people give PRIVACY a lot of credit in real life to the way we put efforts writing and commenting about it online. More and more people are trying to share their lives on Twitter and Facebook, yet, we are talking of privacy.
The default is to go back to feature phone if one has any concern about privacy. I am not sure of any product that can offer privacy in the digital age unless they are not selling ads. Personally, I do not see the risks and do not put a lot of thoughts on this privacy thing. I do not see the personal harm that you are harvesting my data and using annonymously.
As long as my financial security is not compromised ( my bank acount information or my credit card passords ) and my relations are not compromised , I would not give a damn if they capture all other kind of personal data about me .
