Zero-Party Data
Zero-party data is information a customer intentionally and proactively shares with a business, such as preferences, intentions, and goals. It is a high-value subset of first-party data because the customer declares it directly, removing the guesswork of inferring intent from behavior.
Examples include preference center selections, quiz and survey answers, and a declared purchase timeline. The customer is telling you something, not just doing something you happened to record.
Zero-party data is accurate and consented by definition and is collected best in exchange for clear value, such as a better recommendation or a tailored experience. Operationally it lives in the same owned foundation as the rest of your first-party data.
