Why are the hidden settings-folders not deleted when purging an application?

I did

sudo apt-get remove --purge

for several packages, but apparently the personal settings are kept. Is there a command or tool to delete them automatically?

Solution 1:

If you mean the folders in your home folder: No, the package manager never touches anything in a users's home folder.

I don't know of any tool that assists you in cleaning your home folder from config files you don't need any more - but that sounds like a nice idea.
