Zero-Party Data
Information that a customer intentionally and proactively shares with an organisation, such as preferences, intentions, context, or desired recognition.
Zero-party data can improve personalisation and segmentation while reducing reliance on inferred behaviour, provided the organisation offers a clear value exchange and honours the customer’s choices.
A retailer asks customers to select product interests and communication frequency in a preference centre, stores those choices with provenance, and uses them to control recommendations and campaigns.
Self-reported data can be incomplete, outdated, strategic, or biased. The term does not remove privacy obligations, and collecting excessive preferences without visible benefit undermines trust.
It is collected through explicit interactions such as preference centres, quizzes, onboarding choices, surveys, and saved settings. Implementations should record purpose, consent or other lawful basis where required, provenance, timestamp, permitted uses, and mechanisms for correction or withdrawal.
