MacStayOn uses Supabase authentication cookies to keep you signed in and protect account routes. These are required for login, licence management, downloads, admin access, and security controls.
Your theme choice is stored locally in your browser under macstayon-theme. Removing it restores the browser or system default.
Stripe may set cookies during checkout and billing-portal sessions. Supabase, Vercel, Sentry, Google sign-in, Apple sign-in, and other enabled providers may process technical identifiers needed to deliver their services.
Google Analytics is loaded only when configured. MacStayOn does not use third-party advertising cookies. Browser controls can block optional analytics, but blocking essential authentication storage may prevent account features from working.
