Unfortunately, Flox doesn't have a proper exporter for its analytics data. The logs are stored only for two weeks, anyway, before being deleted – there's a Ruby Gem available you can use to download them on a regular basis, but it's probably too late for that in your case (and probably not what you're looking for).
As for the actual analytics data, what you're seeing in the web interface is more or less all there is, and we haven't set up any exportable data format for that kind of information. Furthermore (and if I remember correctly), we don't keep any usage data longer than one year. Extending that stuff was one of the features that were dropped when Holger left Gamua. 😕
I hope that's not too much of an issue for you?
