Help I can't find my old projects

I logged on a few months ago after completing a NFTE Startup Tech course but when I checked my projects weren't there, Can someone help? If so that would be amazing!

Which server and login did you use?

I don't know, is there any way I could check? I think I might have been on a school server, but I'm not quite sure.

If you used ai2.appinventor.mit.edu, your Google address should show at the top right corner of the page.
