Yes, administrative classes (not student electives). Designed for about 20–40 classes; auto-schedule stops above 60.

Where is data stored?

Draft in localStorage plus JSON/Excel you download. Auto-schedule sends the current project to the server for an in-memory OR-Tools solve; it is not written to disk.
