This is semi good advice, but honestly the big dogs (think Google) would have already captured that data, and likely are circulating it about. The best thing you could possibly do for your privacy is to try, and avoid logging data in the first place. That's however easier said than done. Honestly, I care about my privacy, however I've somewhat accepted now that its completely unavoidable as long as your using the internet for purchasing things, which unfortunately is the way the world is going.
