First-Party Data

First-party data is information a business collects directly through its own interactions with people, such as quote inquiries, email subscriptions, purchase histories, or customer service conversations. A landscaping company might use voluntarily submitted service preferences to follow up about the requested work. The term describes the relationship between the business and the data source, not automatic permission to use information for any purpose. Accuracy, security, retention, and applicable notice or consent requirements still matter. First-party data differs from an event parameter in analytics, which is a field attached to a measured interaction. A useful data practice starts by collecting only information the business has a legitimate need to handle.
