   - set `staleTime` to `Infinity` to never trigger a refetch until the Query is [invalidated manually](./query-invalidation.md).

+> `'static'` and `Infinity` look similar but behave differently when `refetchOnMount`, `refetchOnWindowFocus`, or `refetchOnReconnect` are set to `"always"`. With `staleTime: Infinity`, those `"always"` triggers still fire. With `staleTime: 'static'`, they don't. The query stays frozen until you explicitly call `queryClient.resetQueries()`. Use `'static'` for data that cannot change while the app is running: feature flags fetched at boot, user permissions loaded at login, static reference tables. Use `Infinity` when you still want manual invalidation to work.

 - Stale queries are refetched automatically in the background when:
   - New instances of the query mount
   - The window is refocused
