Funny how people used to ask "what is a cloud application", and now they ask "what is a local application" :-)

Local as in "desktop application on the local machine" where you are the sole user.

This, though I think other posters have pointed to a web app/site that’s backed by SQLite. It can be a perfectly reasonable approach, I think, as the application is the web server and it likely accesses SQLite on the same machine.

That commenter's idea clearly wasn't about desktop application on a local machine. That is why I asked.

You mean Andrew's comment? I took it in the broadest sense to try and give a more complete answer.
