Where is lhci server data stored on disk?

[ghost]

We have an old, undocumented setup of lhci on a Windows server with builds/runs being pushed from an on site Azure Devops pipeline. I'm pretty sure that there is no DB involved storing the build so it should be stored on disk somewhere on the server, but I'm unable to find out where. Read the docs but must be missing something regarding the storage.
Another way to ask this is, if I just install lhci from scratch and then run the wizard to create a project. Where is it stored? Another purpose is to be able to delete this old setup and start from scratch. Thankful for help/explanation.
