file path, name of account on computer
If you have this information coded into the project, yes, that will be shared. And if you share photos you made, they might even have gps location data inside.
It is not a dumb question. It is very much needed. Some devs share developer versions or mistakenly zip files into their project that are not part of the project.
So while Itch does not add to those informations, you might not know which information is inside your project to begin with.
