It is esay to hack someone message and privacy because thus app has to scan the what app qr code and in whats scan we will see the msg on it . And the most problem is that is anybody can msg in anoymously and the culpter will be user. For example if I gave the mobile to someone for a few seconds and he had scan my what app code thorught it and gave it back because I don’t know what he has done to it. Then he can msg to my gf or and orther friend withour being typing with myself. This could be for pc perpose but beware. Try to use for good purpose bro
