Abstract

Concepts and technologies for point-to-point data synchronization are provided. A personal area network connection between a first user device and a second user device is established. State change information of first data stored on the first user device is received by the second user device, and second data stored on the second device is updated to reflect the state change to synchronize the first data and the second data. Alternatively, a synchronization message including the state change information of first data stored on a first user device is received by the second user device. The state change information is extracted from the synchronization message, and second data stored on a second user device is updated to reflect the state change to synchronize the first data and the second data.

Claims
