Perch's Use of MySQL

Does Perch store anything but content data in its MySQL database?

That is, does Perch store configuration data there, too?

I'm asking because I would rather not have to sync the MySQL database back from the production server to the development server if I make changes to the markup for the site. As long as nothing I do on the development server needs to go into the database (other than the pure content), I should be fine.
