Funny thing about those aps, they don't really rob you of your privacy, you willingly give it up so you can have something cool that appears to be convenient for you. Use Amazon because of all the stuff they have that you can have sent directly to your house? Great, now they know where you live, what you like, what your shopping habits are, as well as what your bank account is and how much you have. Like Google Maps? Great, now they know where you are at everywhere you take your phone with you, as well as where you've been and (likely) what you were doing there. Like messenger apps? Now they know who you know, who you associate with the most, and what you are talking about.
Sorry, but privacy in this day and age, especially if you use a smart phone, is an illusion at best. There are many things I would like to use, but still won't, because they ask for too much information from me, and I don't want to share it with the whole world. I like having some sense of privacy, even though I know my life really isn't. Only way I could do that is to go completely off the grid, and I don't want to, as I like some of the convenience offered by being on it.
