According to my understanding, after the personalization period of CITIC Credit Card is successfully processed, the bank can check the relevant information. The bank will record your credit card transactions and installment processing in the system, including the installment amount, number of installments, installment interest rate and other information.

The bank updates your credit card account and related data in real time by recording information on installment transactions, and ensures correct processing of repayments and bill generation. This helps the bank monitor and manage the borrower's loan status, including accounting reconciliation, bill generation, interest calculation and other operations.

It should be noted that although the bank can check the information of personalized installment processing, the specific privacy policy may vary by country, region and bank. Under normal circumstances, banks will strictly abide by relevant laws and regulations to protect the security and privacy of customers' personal information.

If you have any doubts or concerns about personal information, it is recommended to directly consult CITIC Bank’s customer service department or refer to its privacy policy for detailed information.
