The device capture step collects five data points from the visitor's browser environment: browser name and version, operating system, device type (desktop, mobile, or tablet), preferred language, and viewport width in pixels. All five are stored in the session record and visible in the visitor detail view.
Like IP capture, the device capture step is transparent to the visitor - no UI is shown. The step executes, records the data points, logs a capture event in the session timeline, and passes the visitor forward. It can optionally require consent before collecting.
Device and browser data is useful for understanding whether your audience is on mobile or desktop, identifying patterns across sessions, and cross-referencing device types with gate outcomes in your analytics.
