User-approved data sharing essentially means giving permission to a third party to use your personal data. This practice ensures that users have control over which data is shared, with whom, and for what purpose.

Zero-party data is information explicitly provided by the customer, usually through direct interaction or surveys, unlike other forms of data, which are typically observed or inferred. It’s like going shopping and telling the store exactly what you are looking for, and by sharing your preferences directly, they can give you personalized recommendations and offers based on what you have told them.
