Where does Serviio store its temporary data?

Does Serviio use the "/var" or "/var/db" directory to store its temporary data before writing it out (permanently) to the serviio directory?
What Serviio files are stored in the "/var" directory (or any of its subdirectories)? Give me the exact names and exact location of where these Serviio files are stored in the "/var" infrastructure.
This is important, because I have software that I want to try with Serviio and if Serviio does store its files (temporarily) in the "/var" directory, then we are talking about a whole different ballgame.
Does somebody have a list of where these Serviio files are temporarily stored?
