After installing the app on your child's phone, you will launch the app and will see the interface with the Login button or Register button.
If you do not have an account yet, you can click the Register button to fill in your username (login name) and your password. After registering, the device will be attached to your account already.
If you have the account already (for example you registered at the user control panel website), you do an authentication (login) to attach the device to your account.
And then you can start to track all the activities of the device.
Go to the website control panel, you will see the log data. If you feel that all are OK, you can hide the icon of application and of course, your child is not able to see the app installed on his phone.
In case you want to show the icon of the application again, make a call on that device with the access code, it will show the icon again.
For trial days, you can use basic features. For more advanced features you can activate a license.
