How can I reset the app and start over from scratch (i.e delete the entire user data-base)

I used the app in the past, and now I wanted to go back to it and everything is quite a mess. I'd like to start over as if I just open it for the first time. I didn't find a way to do it through the app itself, I believe there is a file/directory I can delete?
Sorry if it has been asked before, I tried to look it up but couldn't find anything. Thanks. (I'm using the app exclusively on GNU/Linux, and I do not use any on-line synchronizing).

Update:
I find a way to do it, I uninstalled the app, deleted both the ~/.config/SuperProductivity/ directory and the backup directory and then re-installed it (maybe it wasn't necessary to remove and re-install it, I didn't check).
Well, I don't know how much this would be a useful feature, but it might be worth considering adding a reset button to the app itself. (with a proper warning, of course).

I like the idea of such a button.
Is more user friendly and increases the user experience (UX).

An even quicker way would be

1. pressing Ctrl+Shift+i
2. going to the "Application" Tab,
3. then to "Storage"
4. then click "Clear site data"

But @dsarid solution is cleaner and will remove all of the app data.
