OneFPLLast updated: 18 July 2026. This explains the cookies and browser storage OneFPL uses.
OneFPL uses your browser’s local storage to remember your FPL Team ID and preferences (such as your chosen mode). This is required for the app to work and contains no personal identifiers beyond your public FPL Team ID.
If you sign in to an optional OneFPL account, Supabase sets essential authentication cookies. They keep your session active and contain account identifiers and security tokens. They are not advertising cookies. Signing out clears the active OneFPL session.
We use Google Analytics (via Google Tag Manager) to understand which features are used and to improve the app. It is used only in aggregate — we never send it your FPL Team ID or anything that identifies you.
These load only if you allow them. We ask on your first visit, and nothing analytics-related runs until you choose — if you decline, Google Analytics is never loaded at all, rather than loaded and told to ignore you. Declining is one click and changes nothing about how OneFPL works. To change your mind, clear this site’s data in your browser and we will ask again.
Content pages (such as the blog) may show light advertising. Ad providers may set their own cookies. Core FPL tools are designed to stay clean and fast.
You can clear cookies and local storage at any time in your browser settings. See our Privacy Policy for more.
