"Up to 1,107,494" records (count blank): email addresses, attributes such as birth date, gender, occupation and area, and legacy data of the Subway Club prepaid card discontinued in August 2023 (number, balance then, usage history) that remained in the external system. No credit-card data is held. This stems from the Arara email-platform intrusion (recorded separately); the figure is a subset of the vendor scope and must not be added to it.
