First-Party Data
First-party data is information a brand collects directly from customers on its own channels, and it becomes the core asset for repeat-purchase marketing after third-party cookies go away.
How is it different from third-party data?
Third-party data is assembled by outside vendors tracking users across sites, and browser policy changes have gutted its usefulness. First-party data comes from your own channels, so it's both more accurate and more durable.
How does live collect it?
Broadcast on your own store and watch time, products tapped, questions asked, and whether they bought all attach to the member account. Broadcast on an external platform and that link breaks — so from a data standpoint, where you broadcast decides whether you collect anything at all.

Frequently Asked Questions
Q. Do customers have to register for me to collect it?
Linking purchases to a person requires identification. Anonymous behavioral data is still perfectly usable for improving content, though.
Q. How is it different from zero-party data?
First-party data is observed from behavior; zero-party data is what the customer told you directly through a survey or preference choice.
