What data is stored in the visitor's browser?

Lyftio stores a visitor object (lio_user) in the browser’s localStorage to manage experiment data. This object contains the following information:

_experiments → Identifies which experiment and variation the visitor is assigned to.
_referrer → Records how the visitor arrived on the site (e.g., direct visit, campaign link).
_lastActivity → Timestamp used for session tracking.
_sessionId → A unique ID for tracking the current session.
_id → A persistent visitor identifier (UUID).
