Do you aware that you are selling yourself and allowing someone to profiting!
Yes!! We install apps and most of us do not read TandC and policies and other stuff, we skip them and tick them that's it. That is when things get out of our hands but you can't see any difference , why? because no reviewer almost no one talks about privacy or anything related to that topic.
That's why watching don't rely on YouTube videos(mostly).because they (not everyone) do reviews of apps and smartphones only for making money and to get popularity.
If you want to use an app do your own research spend some time to know things that you dont know already , read about the app and go to the app's official website and read everything (if you want) .
