Privacy notice · version 1.1 · September 1, 2026
Your email stays private. Your call is public.
Frontier Forecast Arena is the independent operator of this site. We separate private account data from the forecast record people choose to publish.
Data we store
ChatGPT sign-in returns an account identifier, email, and display name. We store those privately with your chosen public alias, forecasts, timestamps, official results, and Elo history. Drafts remain only in your browser until you publish.
What becomes public
Your alias, published forecasts, submission times, resolved accuracy, and Elo may appear on a permanent shareable profile and leaderboard. Your email, account identifier, and sign-in display name are never shown publicly.
Why we use it
Private account data restores your calls, keeps one record per participant, limits duplicate prize entries, handles support and deletion requests, and lets us contact an eligible winner. We do not sell personal data or use it for advertising.
Processors and security
ChatGPT Sites and Cloudflare provide application, authentication, and database infrastructure. Resend handles email for the custom domain. Providers receive only the data needed for their service. Access to private account records is restricted to administration and prize operations.
Retention
An active account record remains while you participate. After a verified deletion request, private account data is removed within 30 days. Prize, abuse-prevention, and dispute records may be retained for at most 24 months after settlement. Settled predictions may remain with the account identifier, email, display name, and public alias removed so historical rankings remain auditable.
Access, export, correction, and deletion
Email privacy@frontierforecast.tech from the address connected to your account. We acknowledge requests within 7 days and complete verified requests within 30 days. An export includes your private account fields, published forecasts, and rating events.
Prize communications
If you lead the settled eligible leaderboard, we use the stored email for one notification and one reminder. We never request your ChatGPT or Anthropic password. Digital card details are delivered privately only during the agreed fulfillment window.
Changes
Material changes receive a new version date. Rules and scoring that apply to already-published forecasts are not changed silently. You can contact the operator at the privacy address above.
