There's currently no way to disconnect HubSpot from Orum.

If you wish to uninstall Orum from HubSpot and delete your corresponding data, reach out to our support team in the platform or submit a request.

Customers can contact Support to disable/disconnect the integration. They can optionally choose to delete any data associated with that integration which will take place immediately. If they cease to be an Orum customer, we will delete any data associated with their HubSpot (and any other) integrations within 5 business days.

We don't do anything to the customer's HubSpot instance when they disconnect an integration or churn. 

To complete uninstallation of Orum from your HubSpot account, please perform the steps listed here.
