Unfortunately QQ International doesn’t offer this feature and it’s because of security reasons. However we suggest that you manually save your QQ International contact information regularly in case you forget your password or don’t have an Internet connection.
Go to Contact Manager by right clicking anywhere on your contact list to bring up the Contact Menu.
You can then take a screenshot of the Contact Manager window to have a copy of all your contacts QQ numbers. If you ever lose access to your account, you can still add them back in a new account. Don’t forget to scroll down the entire list and take screenshot of each page.
