Saving is optional and off for every new calculation. Use the consent checkbox and Save on this browser in a calculated result. This notebook survives reloads on this browser profile only; it is not an account backup or a cloud sync.
Restoring makes the saved inputs the tool's new starting scenario. Prices, source references and financial assumptions are not refreshed. Market currency display uses the current dated exchange rates; Irish payroll stays in EUR. JSON exports keep the original USD/EUR inputs unchanged. Clear browser site data also removes this notebook.
