When a visit originates from a Pinterest campaign or verified Pinterest referrer, HueSteps records limited referral metrics: landing path, campaign/Pin identifiers in the URL, timestamp, country, and broad device category. The referrer is used only to validate the traffic source and is not stored.
Before storing network identifiers, the server truncates IPv6 addresses to a /64 subnet and applies HMAC-SHA-256 with a private secret. HueSteps never stores or exposes raw IP addresses. The resulting pseudonymous network identifier estimates unique network origins, not individual persons.
Pseudonymous Pinterest event data is automatically purged after 400 days. If your browser broadcasts Global Privacy Control (GPC) or Do Not Track (DNT) signals, HueSteps completely suppresses Pinterest analytics logging.
