How can I configure where Loki stores its own logs?

We have some problems with a certain Loki instance and I would like to check Lokis logs, but I fail to find these logs or a configuration setting where I can configure where logs are placed (there is way to configure the log level but not the “sink”). As I am on a windows machine I checked the Windows Event Viewer without success.

I am sure that I am missing something, but I fail to locate the information in the documentation (and obviously searching the net for “loki” in any combination with “log” is not helpful either).
