Disclosed is a portable device for processing continuous monitoring data. The portable device includes a data interface that receives a stream of continuous monitoring data from a body-worn sensor. The data is indicative of an analyte in a bodily fluid. The portable device also includes a storage device that can store the continuous monitoring data. The control processes the continuous monitoring data and is switchable between first and second modes of operation during a sensor session of the body-worn sensor. In the first mode of operation, the control is configured to provide video data indicative of the continuous monitoring data for outputting by a display. In the second mode of operation the control is configured to store the continuous monitoring data in the storage device and to block the continuous monitoring data from being displayed on the display. A related method, system and computer program product are also disclosed.
