Cookie Policy

PredictorHQ uses a minimal number of cookies and similar technologies. This page lists each one, what it does, and whether it requires consent. For the broader picture on how we process personal data, see our Privacy Policy.

Cookies we set

Name	Type	Purpose	Duration	Consent
_ga, _ga_*	Analytics — Google Analytics 4	Measure page views, sessions, and events (including the affiliate_click event).	Up to 14 months	Required under GDPR / ePrivacy for EU/EEA/UK visitors.
Session preferences	Essential	Language and display preferences (e.g. EN/ES locale).	Session	No consent required (strictly necessary).

Browser storage (not cookies)

We may use sessionStorage or localStorage to cache lightweight UI state (e.g. dismissal of a promotional banner within a session, a cached region code to avoid repeated network calls). This data never leaves your browser.

Affiliate / attribution parameters

When you click an affiliate link (marked with rel="sponsored nofollow"), the destination URL may include UTM parameters, a referral ID, or similar query strings so our partner can attribute the referral to PredictorHQ. These parameters travel with the click — we do not store a cookie on your device to track it. Affiliate partners include Kalshi, Polymarket, PredictIt, Robinhood, and Opinion Trade.

Cookies set by linked platforms

Once you click an affiliate link and land on a partner site, that partner (Kalshi, Polymarket, PredictIt, Robinhood, Opinion Trade, or another third party) may set its own cookies on your device. PredictorHQ has no control over those cookies. Consult each platform's own cookie policy.

How to opt out

• Reject analytics in the cookie-consent banner when it is shown.
• Clear cookies in your browser settings at any time.
• Use a browser extension that blocks Google Analytics (uBlock Origin, Privacy Badger, DuckDuckGo Privacy Essentials, or similar).
• Install the official Google Analytics Opt-out Browser Add-on.

Changes to this policy

We update this cookie policy when our tooling or data practices change. The "last updated" date at the top reflects the most recent revision.
