You can customize apps by specifying which tables appear in the sidebar.
To hide tables from the sidebar in an app:
Open the table you want to customize from the table bar, click Settings in the table card on the page bar, then click Advanced settings.
Click Advanced Table Settings to expand the section, if needed.
Click the Show in the table bar check box to clear it, and then click Save.
This setting also disables the table name link and the Reports link when the user displays a report from the hidden table.
Tip: Exempt the table from a Quickbase Find operation as an extra step. This prevents records from your private table from appearing when your users search your application.
