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.
