To protect customers' privacy, we require that every user needs to sign up an account on the app firstly. Only users know the account email and password. On the app, users can also add a 2-step verification of their account, like the gesture login or Apple Touch ID, which can protect the account from hackers as well. Surely, if you want to improve the security level, you can access the router setting and turn on Firewall.
