- ensure that you select all needed spaces in the app configuration.
- check your permissions to those Confluence spaces. Multi-Space KB Searcher only runs search in the spaces that are open to public (Anonymous user should also have the permission to view).
the app searches in the spaces that are of the Knowledge Base type, make sure that the Confluence spaces meet that requirement.

How can I make sure no sensitive information is exposed?
You are the boss of your Confluence spaces, and this is up to you which spaces you select to be and not be visible to the world. The app only widens search capabilities but this is done for the Confluence spaces that are visible to public already and even those you can limit in the app settings.
Will you launch a Data Center version of this app?
