Upfront, Panino and child themes

OK - so there is an update for Panino. I've been building out a site using the theme. It is, of course, customised since that is the whole point of Upfront.

But I have not created a child theme, assuming that Panino IS a child theme of Upfront.

Am I going to lose my customisation when/if I update Panino?

Thanks,
