Does HubSpot AI (Breeze) train on your data?

Business plan HubSpot · CRM · Last verified

Trains by default

Trains on business data unless you opt out.

Short answer: Yes, opt-out

"HubSpot may use customer data ... to train and improve HubSpot's own AI models." Super Admins can opt out; opt-outs apply going forward only (no deletion from already-trained models). Accounts with Sensitive Data on are opted out automatically.

Why this matters: Data used for training can't be pulled back out of a trained model, so opting out only protects what comes after. Why training matters →
