This is something you’d need to ask Google.
We have dozens of features in Discourse AI, and they will send data to your preferred LLM provider. For example, the summarize feature will send the topic posts and ask for a summary. If your posts contain sensitive data, that will be sent.
We log everything that is sent to the database, so you can audit it anytime.
And if you have stricter data locality requirements, you can run an LLM on your own servers to keep data under your control.
