Methods, program products, and systems for proximity-based notifications are described. A proximity-based notification system can receive a request to be notified when a contact's mobile device is in proximity to a user's mobile device, obtain permission to receive information associated with the contact, receive the information associated with the contact, detect that the contact's mobile device is in proximity to the user's mobile device based on the information associated with the contact, and notify the user that the contact's mobile device is in proximity to the user's mobile device. |
