In short
No. With Apple Pay, Kesef only learns the amount and the merchant of each payment: it never sees the card number and can't pay with it. With Mercado Pago, the authorisation is read-only: it can read your transactions, but not pay, transfer or touch your balance. You can turn either one off whenever you want.
Kesef doesn't connect to banks and doesn't ask for any bank password. The only automatic inputs are Mercado Pago, authorised on Mercado Pago's own page, and Apple Pay, which works through a Shortcuts automation on the iPhone: it's the phone that tells Kesef a payment happened, with the amount and the merchant, and nothing else.
