U can try android firewall also, its blocks apps internet access... Helpful bcz even if access url private details internet access is not there to pass that information.
For different apps notification sound you can try llama from play store.
Basically it is a location based profile app but it has an option knowns as llama tones which can work for you.
It is really powerfull as u can have different profiles having different sound for diff apps. Which means diff gmail sound at home and diff at office.
