A terminal device and a positioning information processing method applied to a terminal device, where the terminal device includes a processor and a positioning chip. The processor receives a positioning request from a first application program or receives current positioning data of the terminal device from the positioning chip. The first application program is included in the terminal device. The processor obtains a running state of the first application program. The processor avoids sending the positioning request to the positioning chip or avoids sending the current positioning data to the first application program when the first application program is in a positioning service restricted state and the first application program is currently running in the background.
