When you arrive through one of our tagged campaign links, we measure whether that visit leads to a click on a Kalshi or Polymarket market link. An outbound click does not tell us whether you register, trade or make a purchase on the venue.
For this first-party measurement, we use a random identifier stored in your browser tab for up to 30 minutes. We store a hash of that identifier, the registered campaign, timestamps, and the venue, market and page placement of outbound clicks. These records are retained for up to 90 days. They do not contain your name, email, IP address, account identity, raw X click ID or browser fingerprint. They are separate from our existing Google Analytics measurements.
The measurement does not identify people across devices. We report sessions, not exact numbers of people. Ad blockers, disabled storage and privacy choices can leave visits unattributed. The new campaign measurement does not send its session identifiers to X or the prediction venues.
We respect Global Privacy Control and Do Not Track for this campaign measurement. You may also turn it off below for this browser. This choice applies to the first-party campaign measurement described here, not browser controls for other services.
Our existing Google Analytics also receives campaign labels, public post or ad identifiers when available, and the venue and placement of market link clicks. This lets us compare campaign visits with outbound clicks. Our first-party session and click identifiers are excluded from these Analytics events, and URL redaction protects those identifiers and raw X click IDs in automatically collected link events. Google Analytics has its own browser identifiers and measurement rules, so its totals may differ from our first-party counts.
