Sneek peek

So I downloaded norton app lock and activated the sneek peek option in the setting menu, but as far as functionality nothing happens…i logged into my account and I dont see anything referring to sneek peek…i ran a test on my phone and put false codes in to see if it would take a picture but nothing happens…so in short I see the slider moved over to sneek peek being on but thats it, nothing else happens
…any solutions?
