Abstract: In a privacy information generation method, a terminal device displays on a display an interactive element of a privacy settings page for a target application. The terminal device responds to a first gesture operation performed by a user on the interactive element of the privacy settings page, and determines a privacy precision for the target application according to the first gesture operation. The terminal device then generates privacy information based on the privacy precision for the target application when the target application requests the privacy information from the terminal device.
