Beware of the 5 1 credit card housekeeper. After installation, you only need to clear the local data, delete the automatic import mail, cancel the account and delete the 5 1 credit card manager Pro software on the mobile phone, but you only need to download the 5 1 credit card manager Pro software from the mobile phone again. You can log in with tourists, and the credit card information was there before. A software with serious consequences, I wonder what Apple eats, so software can also audit sales?
