The invention provides an information processing apparatus, an information processing system, and a non-transitory storage medium. A method for detecting the deterioration of mental state of a user comprises: obtaining scheduled behavior information that is information about a scheduled behavior of a user; obtaining user behavior information that is information about a behavior performed by the user; calculating a deviation degree between the scheduled behavior and the behavior performed by the user, based on the user behavior information and the scheduled behavior information; and performing a predetermined process when the deviation degree exceeds a first value.
