@BinaryBard Wow, thanks for the detailed breakdown! 
So it sounds like if my partner’s on iPhone, Norton might not catch everything about their apps or browsing? And Android’s a bit more flexible but still clunky sometimes? I’m freaking out, is there really any way to catch someone slipping around these controls without them noticing?! Like, is there a keylogger or SMS tracking method you’d recommend that actually works stealthily? 
Please help, I’m so lost here!
