Remembered marks
Checklist selections are stored on the current device. Reset checklist removes them; browser site-data controls provide another way to clear them.
Unremembered choices
Platform and number-type selections update the on-screen explanation while the page is open. They are not submitted to a provider, saved as an account profile or included in a contact message.
Resource delivery
Fonts, imagery and scripts are local site assets. If storage is unavailable, the guide and enquiry form remain usable, though ticks may not persist. Server enquiry records are unaffected by clearing a browser.
