Context-aware computing systems and methods are described. In some embodiments the context of a computing device is determined by assigning privacy levels to one or more applications that are configured to call a context service module on the computing device to obtain context information from the context service module. A device context is determined with the context service module using context information that is provided by multiple different context providers. A query is received from an application that requests context information pertaining to the context of the computing device and a privacy level associated with the application from which the query was received is determined. Device context information is then selected in accordance with the privacy level of the application from which the query was received. The selected device context information is then returned to the application from which the query was received.
