What a wonderful project!
Hopefully this can be of great use to many players who wish to improve their 
game.

I see immediately where Ingo Althofer has made a reasonable objection to your 
privacy statement.
Now I am visiting your site and the full privacy statement, very prominently 
displayed is:

   By submitting any data, you agree that we can make further use of
   it. All the data we publish (here or in any future papers) will be
   anonymized, which means that no information about any particular
   user will be published, or ever given to a third party.

I would recommend the tiny grammatical improvement of adding the word "any" as 
shown in red.  But this policy seems to be just what visitors will want to see.  
Incidentally, you might want to take a look at:

   
http://arstechnica.com/tech-policy/2009/09/your-secrets-live-online-in-databases-of-ruin/

which has some nice warnings about anonymization.  As long as you never release 
anything but grouped statistics, I think you would avoid this trap.  But again, 
it is good of Ingo to have urged you to take care in this regard.

If you ever make publicly accessible on your site anything like:  "Look here are about 50 
games of "TheCaptian" on KGS, with an analysis of their style, then that is a 
problem.  (My apologies for picking out one of my favorite players to watch and bringing his 
nickname in to the example.)

Here are a couple more thoughts about privacy and your site:

1. Since KGS makes these so freely available, then actually you do not
need "TheCaptain"s permission to do this analysis, do you? Hopefully you do not create a violation of KGS's terms of use or
   privacy policy whatever that might be (I don't know if they have one).

2. Also, suppose "TheCaptain" was actually my nemesis and I wanted to
   learn how to beat him. Does anything on your site prevent me from
   pretending that I am him and submitting a bunch of his games for
   analysis? Then I would get the recommendations of how to beat him
   directly, I guess.

Given this, Ingo may have even deeper concerns vis-a-vis your site than he has 
yet voiced.  But personally, I don't disagree with anything I see you doing.  
For instance, I don't think there is anything wrong with either 1 or 2 above.  
Just that I thought they were worth thinking about.

                            I plan to submit a bunch of my games,
                            -- Mark Goldfain
