What LG (and Samsung and all the other electronics companies) are doing is profiling the user to sell targeted advertising. This is technically not personal information, and that's a grey area for those companies when communicating to the public.

People here generally don't like to hear that, but Apple is doing the very same. There's even a study-paper on how they do this without collecting personal information [0]

So when a company yells out how it's not collecting your "personal information", the statement actually doesn't cover what has been discovered here from all I can decipher from this "research"
