Information, with room for choice.
The required session retains your selected frames, upholstery, planning measurements and security token. Submitting an order records the selected pieces, current amounts and delivery contact fields. Card controls are unnamed browser inputs and are not included in the order record.
Optional room memory is off until you select it. It stores only room length and end allowance locally. Withdrawing deletes that saved pair and blocks later reads or writes, including from a previously opened tab.
A separate session preference remembers a dismissed welcome panel. Joining the studio mailing list stores your email and explicit choice independently of optional room memory.
