HubSpot Breeze
HubSpot says the AI service providers used for Breeze and other HubSpot AI features are not permitted to use customer data for model training, and HubSpot enforces zero data retention with those providers wherever possible.
The public infrastructure FAQ focuses on third-party AI providers: customer data is not used by those providers for model training. Customers can manage AI feature access in HubSpot settings.
No opt-out is required for the stated third-party training baseline. Admins can turn AI features off or manage which AI processing paths are enabled.
Breeze agents and assistants can act on CRM, marketing, and service data according to HubSpot permissions and connected tools, so access scope remains material even without provider training.
HubSpot says it minimizes retention with AI providers, including zero-day retention where possible. HubSpot-side records, logs, and CRM objects remain under HubSpot platform retention.
HubSpot publishes AI model cards describing controls and risks; the reviewed FAQ does not provide one short human-review statement for every Breeze action path.
