Your Firebase project is where the SlackVault archive actually lives, which is the reason there is no subscription to pay. You create the project, enable Firestore, and paste the web config into SlackVault so the extension knows where to write. Everything after that counts against your own Google quota, so it is worth understanding the free-tier limits before syncing a large workspace.
