This lesson shows how to decide which personal data to share with AI. We start by identifying data items like name, address, credit card number, favorite color, and hobby. Each item is checked if it is sensitive. Sensitive data such as name, address, and credit card number are marked as 'Do NOT share' to protect privacy. Non-sensitive data like favorite color and hobby are safe to share. Key moments explain why names and financial info should not be shared, and why hobbies are safe. The quiz tests understanding by asking about decisions for specific data items and how adding new data affects the tracking. Remember, always protect your sensitive personal data when interacting with AI.
