what is zero party data
Quick Scoop: what is zero party data
Zero-party data is information a person **intentionally and proactively shares** with a brand, such as preferences, purchase intentions, interests, or profile details. It is “zero- party” because it comes **directly from the source** , with no middle step or inference involved.In plain language
If someone fills out a quiz, picks product preferences, updates a profile, or answers a survey and knowingly shares that information, that is zero-party data. Unlike behavioral data that is inferred from clicks or browsing history, zero-party data is explicitly given by the customer.
Why it matters
- It is usually more accurate because the customer is telling you directly.
- It helps businesses personalize offers, recommendations, and messaging more respectfully.
- It fits privacy-first marketing better because the sharing is intentional and transparent.
Simple example
A skincare brand asks, “What is your skin type?” and the customer selects “dry.” That answer is zero-party data because the customer knowingly provided it for personalization.
