Embodiments of the present invention relate to a call record synchronization method, a cloud platform, and a terminal. The method includes: detecting, by a first terminal, an input operation for requesting to display a call record; and after the first terminal detects the input operation, displaying, by the first terminal, a merged call record, where the merged call record is a call record obtained after merging of a call record of the first terminal and a call record of a second terminal, and the merged call record includes a device identifier of the first terminal and/or a device identifier of the second terminal. According to the embodiments of the present invention, a user can use the merged call record to identify call answering or making statuses on a plurality of terminals, without querying a plurality of call records. This improves user experience.
