MAHJONG PARLOUR / INFORMATION
A careful record of your choices.
The required session keeps chosen sets, quantities, table-width notes and the form-security token. An order record contains these choices and the delivery details you enter. Unnamed card controls remain in the browser and are not part of the order record.
Saving a preferred ruleset is optional. The guide reads or writes it only after permission. Remove saved ruleset deletes that store-owned entry; the same check prevents an older tab from writing after withdrawal.
The dismissed welcome window uses a session preference. Mailing-list permission records an email and opt-in separately from local guide storage.
