Disclosed are various examples for an application settings module that provides uniform access to diverse types of data, such as mobile device settings. A client device, such as a mobile device, can be configured through execution of program instructions to access a schema file comprising a definition of a plurality of keypaths, where individual ones of the plurality of keypaths uniquely correspond to one of a plurality of device settings and the keypaths are defined in the schema file in association with a plurality of methods. The client device can identify a function invoked using one of the keypaths to read or write a corresponding one of the device settings, whether stored locally or remote, and, in response to the function being invoked, execute a portion of the methods corresponding to the one of the keypaths in the schema file and return a result to a requesting process.
