Not safe. "I Love Card" has recently cooperated with Sino-British Life Insurance. Anyone who registers on their website and submits personal information will by default be allowed to hand over their information to the insurance company for promotions, including name, phone number, and address. It was all sold and leaked! In "I Love Card"'s own forum, the "Community Management" area was full of curses.
To apply for a credit card, look for a bank or bank website, do not trust third-party websites or intermediaries~
