No backend, but that'd be a relatively simple task to add one.
As of right now, all data is instantiated through a seed script. I've got the mod data stored in a python dict format, these are then consumed by the seed script each time I do a deploy (after dropping/recreating the db.) It might sound sort of crazy, but it's been a good way to ensure state without needing to care about the database itself (and works because I'm the only cook in the kitchen right now .)
