Curio stores assets as files within the project by default. It's browsable and pretty readable. You can also configure it to leave the assets in place on the file system and just point to them so you can manage those yourself if you want. You can export the project as HTML if you want and walk through the project in a web browser with the underlying assets available.
If you have something better in mind in terms of exporting or data storage you can request that. I've emailed the main developer (George, george _at_ zengobi dot com) and he responds personally pretty quickly.
