What is first-party data?
First-party data comes from a business's direct interactions with its customers or visitors. An order in its checkout, a support request, and an event from its website are examples. The business controls the collection point and can explain what it will do with the information.
First-party describes the relationship in which data was collected. It does not mean the data is anonymous, accurate, or free to share with any vendor. An email address collected for a receipt, for example, cannot be sent to every ad platform just because the store collected it directly.
How can teams use it?
- Join permitted website, app, and backend events around a known account or order.
- Compare campaign reports with actual purchases or qualified leads.
- Build reports in a data warehouse or customer data platform.
- Send allowed conversion events to destinations through a controlled server pipeline.
Document the purpose and consent status with each data flow. If an event goes to several destinations, define which fields each one may receive. This is the practical advantage of first-party data: the business can set and enforce those rules at collection and delivery.
How Hardal handles it
Hardal collects events on your own subdomain and stores them in the region you choose, so the data stays first party from collection to delivery. First-party vs third-party cookies covers the browser side of the distinction.
