Zero-party data

Zero-party data is information a customer intentionally and proactively shares with a business, such as preferences, purchase intentions, or feedback given through a survey, quiz, or account setting. It differs from data a business simply observes or infers, because the customer chooses to volunteer it directly, usually in exchange for a more relevant experience, a better recommendation, or some other clear benefit.

For a subscription business, zero-party data is especially useful because a subscriber relationship already includes many natural moments where a customer might share preferences directly, such as during onboarding, at plan selection, in a cancellation survey, or through account settings. A subscription platform such as Recurly can capture and store certain account and subscription attributes over the life of a customer relationship, but the substance of what counts as zero-party data, deliberately volunteered preference and intent information, generally needs to be collected through dedicated surveys, preference centers, or onboarding flows built by the merchant. For Recurly Commerce specifically, the platform knows which subscription offering a customer purchased and can see certain lifecycle behaviors, such as when a subscriber skips a shipment, and it presents a survey at cancellation to log the customer's stated feedback.

Why zero-party data matters for subscription businesses

As privacy regulations tighten and third-party cookies and tracking identifiers become less reliable, zero-party data has become an increasingly important way for a business to understand its customers without relying on inferred or purchased data. Because the customer chooses to share it directly, zero-party data tends to be more accurate and more directly usable for personalization than data pieced together from behavioral signals.

For a subscription business, zero-party data also has a direct connection to retention. Understanding why a customer subscribed, what they value most, or why they are considering cancellation, information a customer is often willing to share if asked directly, can inform targeted offers, product changes, or win-back campaigns that behavioral data alone would not surface as clearly.

How to use zero-party data in a subscription business

Collecting zero-party data works best when it is built into moments the customer already expects to engage with, rather than added as an unrelated request:

• Ask new subscribers about their goals or use case during onboarding, and use the responses to tailor the initial product experience or communication. For Recurly Commerce merchants, this onboarding step typically happens within Shopify's purchase experience on the merchant's storefront, and Recurly does not have visibility into that collected data.

• Include a short, optional survey at the point of cancellation to understand the customer's stated reason for leaving, which can inform both immediate win-back offers and longer-term product or pricing decisions.

• Build a preference center where subscribers can directly indicate what kinds of communications, features, or offers they want, rather than inferring interest from open and click behavior alone. Recurly's Customer Portal supports some of this today, though it is more focused on subscription management, such as plan and payment changes, than on broader communication or feature preferences.

• Be transparent about why the data is being collected and what it will be used for, since zero-party data depends on customer trust and willingness to share.

• Act visibly on the data that is collected, since customers who share preferences and never see them reflected back are less likely to keep sharing information in the future.

Benefits and examples

Using zero-party data thoughtfully offers several benefits to a subscription business:

• More accurate personalization, since the information comes directly from the customer rather than being inferred from indirect signals.

• Reduced dependence on third-party data sources, which are becoming less available and less reliable as privacy regulations and platform changes limit tracking.

• Stronger customer trust, when data collection is transparent and customers can see their input reflected in the experience they receive.

• More useful retention and win-back insight, since a customer's stated reason for canceling is often more actionable than an inferred behavioral pattern.

As an illustrative example, imagine a subscription business adds an optional one-question survey to its cancellation flow asking customers why they are leaving, with options such as price, missing features, or no longer needing the product. If 40 percent of cancelling customers answer the survey and half of them select price as the reason, the business now has a direct, customer-stated signal it can act on, such as testing a lower-tier plan or a retention discount specifically for price-sensitive cancellations, rather than guessing at the cause from usage data alone.

Zero-party data vs first-party data

Zero-party data is information a customer deliberately and proactively shares, such as answers to a preference survey or a stated reason for canceling. First-party data is information a business collects through direct interactions with the customer, including behavioral and transactional data such as purchase history, page views, or login frequency, which the customer does not explicitly hand over in the same intentional way. Both are collected directly by the business rather than from external sources, but zero-party data reflects what a customer says about themselves, while first-party data reflects what the business observes the customer doing.

Frequently asked questions

Is zero-party data the same as first-party data? No. Zero-party data is explicitly and proactively volunteered by the customer, such as through a survey or preference setting. First-party data includes any data a business collects directly, including behavioral data the business observes rather than data the customer actively chooses to share.

How is zero-party data typically collected? Common collection methods include preference centers, onboarding questionnaires, surveys (including cancellation surveys), quizzes, and account settings where a customer can indicate interests, goals, or preferences directly.

Why has zero-party data become more important? As privacy regulations restrict tracking and third-party data sources become less reliable, businesses increasingly need data that customers choose to share directly, which does not depend on tracking technology or third-party data brokers.

Does collecting zero-party data require special disclosures? Businesses should be transparent with customers about what data is being collected and how it will be used, consistent with their privacy policy and applicable privacy regulations, though specific legal requirements vary by jurisdiction and should be confirmed with legal counsel.
