Match History

So I got curious about my match history (% of matches in various game modes, % wins on each map/champion, total wins for each map/champion) and short of writing down the details for every single match, I do not really see a way to analysis my match history on a high level. Is there a way to download our match history? Or is here a website where such information could be easily gleaned? A friend had pointed me to Lolking and Elophant as possibly having this information, but they do not seem to have it either.
