Dead Center Studios LLCuses a small amount of browser storage to run Binder Boss. Most of it isn't cookies at all — your collection lives on your own device in localStorage, which is why the app works without an account. This page lists everything and why it's there.
Strictly necessary
These make the app work. Turning them off breaks sign-in or loses your local collection, so they aren't optional.
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
| Supabase auth session | Cookie | Keeps you signed in and refreshes your session. Set only after you sign in. | Until you sign out or it expires |
| bb-demo | Cookie | Records that you explicitly chose to try the demo without an account. | Until cleared |
| Collection & preferences | localStorage | Your binders, ownership, wishlist, theme and dismissed hints — stored on your device so the app works offline and without an account. | Until you clear it |
| Card catalog cache | IndexedDB | Caches card data so browsing is fast and uses less network. Contains no personal information. | Up to 30 days, then refreshed |
Analytics
These help us see which features get used. They are not required for the app to work.
| Name | Type | Purpose | Lifetime |
|---|---|---|---|
| PostHog | Cookie / localStorage | Product analytics — which features get used, and where people get stuck. Tied to a pseudonymous device identifier, not to your name or collection contents. | Up to 12 months |
