Here at Nubank we use direct mail as a communication channel with people that eventually could be interested in our products. To send these mails we made a partnership with Boa Vista, a data bureau that gathers informations from brazilian consumers. Aiming for data protection, in this process Nubank does not have access to any private information and does not interferes in credit score. To stop receiving Nubank's Direct Mails you only have to acess sou.nu/transparente and type your CPF. This information won't be stored and will be solely used to guarantee the interruption of mail sending.
