I'm the creator of Fugu (https://github.com/shafy/fugu https://github.com/shafy/fugu), if you're looking for an event-based analytics solution that is open-source, free and self-hostable. Fugu doesn't track unique users, just anonymous events. I also offer hosted version if you don't want to deal with hosting (currently using Digital Ocean with their Frankfurt data center, but will switch to an EU company soon).
