Yes! If you decide to move, we'll be sorry to see you go, but your data is yours.
Just ask us, and we'll zip up all your uploaded images and make them available for you to download. Our software is based on an open-source content management system called Drupal. We'll create a dump of your database for you, as well, which you can use to spin up your site elsewhere. This database includes blog postings, product information, order history, your customer list, and so on.
However, there are some gotchas: first, getting the site running on another host is not a trivial undertaking. You may have to hire someone knowledgeable in Drupal to do that for you, and this may be expensive. And you can't take our dashboard, themes, or custom code with you -- those we can't share, as they are what make our business special. Finally, you have to be paid up. Only fair.
