Abstract: Implementations relate to sharing user activity data with other users. In some implementations, a method includes evaluating one or more actions of a second user to detect that the second user is interested in one or more attributes of one or more activities performed by a first user and described in activity data of the first user. A request is provided to the first user to share at least a portion of the activity data with the second user. The method receives, in response to the request, an indication from the first user to share a designated portion of the activity data with the second user. The method causes the activity data to be made accessible to the second user, and provides information for presentation via a device to the second user, where the presented information is derived from the shared portion of the activity data.

Abstract: A system comprising a processor and a memory storing instructions that, when executed, cause the system to determine an identification for a user; determine a location of the user; retrieve a first set of information related to the location and the identification; retrieve relationship information using the identification for the user; determine notification information by filtering the first set of information using the relationship information; generate a notification related to the location of the user and including the notification information; and provide the notification for presentation to the user. The disclosure also includes similar methods and computer program products.

Abstract: A system comprising a processor and a memory storing instructions that, when executed, cause the system to determine an identification for a user; determine a location of the user; determine a place associated with the location; identify an interaction capable of being performed at the place for the identification; communicate with a service to perform the interaction; and record the interaction with the service in a place history associated with the identification. The disclosure also includes similar methods and computer program products.
