Cloud Search [q] !!privacy guard help!!

Hello guys please help me. I am currently using C10.2 build 20131118 (flawless rom btw) and i want to know if privacy guard is full FUNCTIONAL. What i mean is it able to break apps? Or cause some kind of error to an app? Because i been reading on internet that google kitkat's APPOP'S was stripped from the rom as it wasn't stable.
Google like to chat everyone knows the nsa paid em to remove APPOP'S.
But other apps that use similar features i have heard can ruin apps...so plz tell me if cm privacy guards doesn't

Many thanks!!
