One optional preference
The Storage preferences control lets you save a simple notice acknowledgement on this device. It does not hold a user profile, financial data or calculator values. Clearing the checkbox removes the acknowledgement; clearing browser site data has the same effect.
Calculator behaviour
The calculator reads the values currently shown in the form. It does not save them between visits or transmit them. Refreshing the page returns the illustrative example values.
