Configuring device data streams (DDSs) of a mobile device is described herein. DDSs can include sensor data (captured from one or more sensors of the mobile device) and user-specific data (including application data from applications executed via the mobile device, as well as non-application data). DDS configuration parameters define modifications for the user-specific data and/or the sensor data of the DDS; these modifications can include removing or altering the user-specific data and/or the sensor data. DDSs can be sent to an external storage device via a network, and DDS modifications can be made at the mobile device or at the external storage device. Modified DDSs can be provided to requestors, and thus, the DDS configuration parameters allow a user to control what data is, or is not, included in a DDS for reasons related to privacy, data usage, etc.
