Why must Google Play Store be used? Google accounts are the most perfect tracker. They personally identify users, track global position, business transactions, banking, credit card, medical information, Facebook, Twitter, etc. Basically having a Google account is required to use Google Play Store. Having a Google account means giving up all privacy. I don't have an account on my phone on purpose. I don't have a Google account on the internet either. The last one I had I canceled because they were reading my email sharing it with third party data and business, and sending me advertizing related to my medical issues. The last straw was receiving 40,000 redirected complaints in my email over problem android apps.
