## Nauti's Take

The study finally delivers hard measurements and is an opportunity for data protection authorities to act concretely against tracking in chatbots. The risk is significant: chat titles and links often reveal sensitive topics, and even rejected cookies fail to stop most trackers. For you, that means processing confidential content only in business or API accounts with clear data protection agreements and using share links sparingly.
