Privacy Policy

What GRDX1 uses

GRDX1 uses Supabase authentication for sign-in, Google AdSense for advertising, local storage and session storage for guest IDs and saved predictions, and API requests to motorsport data services such as OpenF1, Jolpica, and the F1 CSV dataset bundled with the app.

Information that may be processed

• Account information returned by your sign-in provider and Supabase.
• Guest and prediction identifiers stored in your browser.
• Saved prediction history that may live locally or in Supabase, depending on account state.
• Ad-related identifiers and cookies handled by Google AdSense.
• Requests made to third-party motorsport data services to load race and circuit information.

How the data is used

We use this data to authenticate users, show race predictions, keep saved simulations available, load public race data, and display ads where they are enabled. GRDX1 does not attempt to build a broad consumer profile outside the app experience described here.

Third parties

GRDX1 relies on third-party services for authentication, advertising, and motorsport data. Their own policies govern how they handle information they receive through their systems.

Updates

This policy can change as the app grows or new services are added. The footer links always point to the current public policy pages.
