I have just found out about the wonderful world of Tor. I have it on my PC, but my question is: Can my internet company and/or phone service see what I'm searching? I understand that it is encrypted but what can they see and if they can would a company just randomly say "oh he is encrypted lets find out what he is doing?" Also I have an Android LG K7 non rooted. What good apps are there that will help secure my phone?
The point of your communications being encrypted is that your ISP cannot see what you are doing. Your data is encrypted using cryptographic keys that only you and the Tor network know.
Your ISP would be able to tell, if they cared to look, that you are in fact using Tor. But they would not be able to see what you're using it for. Chances are, they will never care to look.
