• receiving a plurality of transmissions from a geolocation device;
• determining, based on the plurality of transmissions, a location of the geolocation device;
• determining, based on the plurality of transmissions, a velocity vector of a user;
• training a machine-learning model to predict trajectories of the user using historical geolocation data for the user;
• predicting a trajectory of the user by applying the trained machine-learning model to the velocity vector of the user, the location of the geolocation device, and the historical geolocation data for the user;
• determining that the trajectory will lead to a vicinity of the promotional retailer;
• and
• immediately upon determining that the trajectory will lead to the vicinity, transmitting a notification to the user of the promotional offer associated with the promotional retailer.
