Why track the user

The prevoius version was great, Now it wants you to log in with Google or FB. Why do you need my info except to track my usage of everything and everywhere I go?
They say we want you to log in because so we can be sure of your identity. why do you care who I am, Not even UPS,USPS,Fedex, or any other service cares, all they require is that you input the tracking number. for this reason i had to delete the App
