The disclosed systems and methods provide organization, small group, and particularly family-oriented communications platforms, with computing device applications and services allowing users to post, store, organize and share transactions, events, stories, updates, conversations, photos, physical location information and videos and other small group shared, or family-related, information within specified small group units, including specified family units. A content-controlled data and information exchange environment, as a local unit network, is provided that effectively firewalls content providers from gaining insight into the information exchanged by, and preferences of, any individual member of the group, while maintaining transparency into the interests, goals, objectives and data exchange preferences of the group. These objectives are implemented via a specific communications gateway between the local group network and external communication nodes.
