Indeed we do. brainCloud has a rich set of cloud data APIs for just such a purpose.

brainCloud data is stored in what we call entities - which is our name for custom JSON-based objects.

While brainCloud supports multiple types of entities, for user data you would want to user our User Entity API. 

You will find more backgroun info here - http://getbraincloud.com/apidocs/api-modules/data/

Happy coding and good luck!
