3 months I can live with :-) Can someone from WMF just confirm what data is kept for how long?
The exact time is confidential.
Err, no, I don't think so. It's not defined in the files at http://noc.wikimedia.org/conf/, which means it should be using the default, as defined at http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/CheckUser/CheckU ser.php?revision=106556&view=markup. From that file:
--- # How long to keep CU data? $wgCUDMaxAge = 3 * 30 * 24 * 3600; // 3 months ---
The last attempt to change this value (without community discussion) was summarily shot down: http://svn.wikimedia.org/viewvc/mediawiki?view=revision&revision=40847.
That's only CheckUser data, though. I'm not sure what David wants confirmed from the Wikimedia Foundation. Different data has different expiries. A lot of it is permanent (e.g., revisions aren't going anywhere for the most part). I guess the question is specific to the ClickTracking extension: https://www.mediawiki.org/wiki/Extension:ClickTracking?
