Systems and methods for capturing and monitoring the health, safety, and/or activity of a user are described. In one aspect, the system generates a data usage pattern for the user and monitors the user's current data usage activity to detect data usage deviations from the user's usage pattern. When a deviation is detected, the system may send an alert message to the user or another user indicating that an anomaly may have occurred, permitting the user or another user to respond to the anomaly.
