Abstract: Method and System for Extraction of Event Data from User Devices A method and system is provided for extraction of event data from user devices (216). The system (104) comprises a data identification component (210) configured to identify a metadata from a pre-existing location on the user device associated with predefined event types. The metadata is stored in the pre-existing location on occurrence of an event on the device and a change in a state of the event. The system further comprises a data extraction component (212) configured to extract the metadata from the pre-existing location. The data extraction component (212) generates event data based on the metadata. The system comprises a data transfer component (214) configured to detect a network (106) and on detection of the network (106) transfer the extracted event data to a backend server (102) over the network (106).
