A social application provides a user interface that allows private or non-public interactions by users in a relationship (e.g., a dating or family relationship), which acts as a “private space” for those users. The private space can be created behind a main interface of a social application so that it is easily accessible by swiping away or otherwise revealing the private interface. Users can easily return to the main interface, such that a user can flip back and forth between private and more public environments. The private space can include user interfaces accessible via tabs or links, such as a homepage interface, a chat interface, a photos interface, and a dates interface that together allow users to communicate privately, share photos and important dates. One user can also receive notifications in either the main or private interfaces that notify the user of the other user's actions in either interface.
