Privacy policy

On September 22nd, 20 18, Apple changed its privacy policy. Therefore, the rating function will be formed according to the number of phone calls and emails handled by users. In order to identify and prevent fraud when shopping, the information when using one's own equipment, including the number of calls answered and emails sent and received, is used to compile credit rating, and how to use these changes to prevent fraud.

The new changes also apply to devices that can't send emails and make phone calls.
