Customer-authorized platforms
StefanBrain can connect to Slack, Google, and other customer-authorized services when a customer enables those connectors. Those platforms are generally the customer's selected source or destination systems rather than StefanBrain sub-processors. Data is exchanged with those platforms only as needed for the user-authorized connector features.
AI processing and model training
StefanBrain sends customer content to AI providers only to fulfill user-requested tasks. StefanBrain does not sell customer data and does not use customer content to train generalized AI or machine learning models. We do not opt in to third-party provider model training on customer content unless expressly authorized.
