First-party data is information your audience has shared directly with you (email, phone, opt-in preferences, purchase history) on your property. It is more durable and more legal than data inferred from third-party platforms, and on hashtag.org every portal owner gets first-party data on its visitors and members by default.
Creator economy & platform risk
First-party data
Visitor info you collect directly through your own portal, not borrowed from a platform.
