Direct answer

Minimize what the model and logs see, redact PII, know your subprocessors, set retention, and document lawful basis. “The model is smart” is not a privacy program.

Data minimization

Send only fields required for the task. Drop free-text dumps that contain IDs and secrets.

Redaction

Mask emails, phones, card data before model and before external log drains.

Subprocessors

Model APIs, email, CRM - list them, review DPAs, understand training opt-out flags where relevant.

Retention

Debug windows vs long-term audit. Delete or aggregate aggressively.

Cross-border

Legal review when EU personal data hits non-adequate regions - process, not a blog disclaimer.

How Northstar fits

Privacy constraints belong in the pilot brief: how to brief a studio.

FAQ

  • Usually a bad idea for confidential data. Use approved API paths with controls.
