PRIVACY
Your data, explained.
MVP privacy notice · 20 September 2026.
Data used in this version
The public MVP does not offer account registration, collect email addresses, or accept user-submitted predictions. Market searches and filters are processed in the browser. No analytics or advertising SDK is included by the application.
Local watchlist
Following a market or model stores its public identifier in localStorage under forecast-arena-watchlist-v1. This stays in the current browser, is not sent to our database, and does not sync across devices. Remove individual follows or clear the site’s browser data to delete it.
Hosting and external links
The hosting provider may process ordinary request metadata such as IP address, user agent, requested path, and timestamps to serve and secure the site. Retention follows the provider’s configuration. External reference links take you to independent sites with their own privacy practices.
Future changes
Account creation, alerts, or personal forecasts will require an updated notice describing the operator, contact channel, purposes, retention, and user controls before those features open. No personal data should be submitted to this demo.
