Digital shadow and surveillance is wickedly accurate and legit. Digital shadow allows your phone to track down your location every day everywhere you take your phone to. My phone knows where I am at, in which country, at what time, and when. Although I can think of a couple situations when this could be practical maybe… The rest is just plain weird and creepy… I did not know that my location was turned on. Moreover, the location times how long you stayed at every location. If your phone got lost, people would have access to everything about you through your phone even where you spend most of your time… This is an insane lack of privacy, security, and is very dangerous and threatening to our general safety, as it really has every proof of where we spend our time.
