Abstract: A tracking system is provided that tracks user browsing activity while maintaining user privacy. It is determined whether a cookie is stored in local storage of a client device. If the cookie is not stored: a tracking identification (ID) is generated; the tracking ID, a cookie rotation timestamp, and a failed request counter in a generated cookie is stored; and the generated cookie is copied and attached to a transmitted event. If the cookie is stored: it is determined whether a time indicated by a stored cookie rotation timestamp is in the past; if the time is in the past, a flag requesting a new cookie value is set for a transmitted event; and if the time is not in the past, the stored cookie is copied and attached to a transmitted event.
