Zero-party data refers to information that customers intentionally and proactively share with a brand. This can include preferences, purchase intentions, personal context, or how they want to be communicated with. Unlike inferred data, this type is voluntarily provided—making it highly accurate and privacy-compliant.
It differs from first-party data, which is collected through user behavior (like clicks or purchases), because zero-party data is explicitly given rather than observed.
As privacy laws tighten and third-party cookies fade out, zero-party data has emerged as a cornerstone of personalized marketing. Users are more willing to share details when they understand how it benefits them—and when transparency is built into the exchange.
This type of data builds trust while allowing brands to deliver relevant messaging, offers, and experiences.
