NetGuard https://play.google.com/store/apps/details?id=eu.faircode.netguard https://play.google.com/store/apps/details?id=eu.faircode.ne... allows for blocking traffic for apps per-domain and per-app. AFWall https://play.google.com/store/apps/details?id=dev.ukanth.ufirewall https://play.google.com/store/apps/details?id=dev.ukanth.ufi... patches iptables to block domains used by apps that are not allowed network access. I did Android QA for a VPN/Proxy app. Had to benchmark battery usage and verify that we upgraded to SPDY properly. A lot of rooting, and tcpdumping. Eventually we got a WiFi network set up by sysadmins that mirrored traffic to one Ethernet socket. Plugged it in on a local SSH-accessible machine and I could tcpdump the whole WiFi traffic without fiddling with devices. Facebook and Instagram are awful network hogs. Both send a lot of packets every 5-10s when the screen is on to Facebooks tracking domains. I removed both and haven't looked back since I saw that. Google and other tracking companies of course are not better, hence the apps mentioned at the top. This is not a viable solution long-term though. They will find ways to eventually circumvent these restrictions. Now I'm thinking about setting up the same thing I had at work at home, just to see what kind of crap goes through my network daily. You're on Windows 10? Guess what Microsoft does. Install Wireshark and check for yourself how much MS domain hits you get. Not to mention HTTP traffic from random apps and/or websites that circumvent privacy protection domain lists. The implication here is that you're the product but not for that company or another. You're for all of them, ISP included. The more crap leaks on your network the more they know and sell. As a side note, I have no idea why DNS traffic still goes in pretty much plaintext... Have you heard about tracking data exchanges? The overall problem is that everyone is spying on you on multiple levels because there's money to be made on profiling. Facebook just grabs the headlines. Apps listening to you are scary but the fact is you don't have to speak to be heard by them.
