Cookie Policy
This page explains the cookies and browser storage used by Dead Cold Cards.
Current technologies
The current application uses Supabase authentication/session cookies so signed-in users can stay signed in and access their account features. These are treated as strictly necessary for the account service.
The application also stores a small number of preferences in browser local storage: card reveal animations, device-motion tilt, and market preference. These settings help remember how the interface should behave on the same device.

Users can clear cookies and local storage in their browser settings. Clearing strictly necessary session cookies will sign the user out. Clearing local storage will reset device-level interface preferences.
