Techniques are for provided located-based contextual services to users by automatically creating location-based contextually relevant communication sessions that may take on a variety of forms, including contextual chats and micro-local services that are ephemeral, curated by a location owner and personalized by a user. As a user's context shifts throughout the day (from work to shopping to entertainment, etc.) the presented techniques filter content differently based on what the user may care about at a particular moment when the user is at a particular venue. The automatic creation and deletion of an ephemeral space/channel provides a dynamic application that changes its content or behavior based on a user's location. The user may control the interactivity level based on an adaptive user identifier by which a user's identity may take on different versions depending on location and time of day.
