To monitor your kid's activities, you will need to install SecureTeen software directly onto kid's devices. But there is no need to install SecureTeen application on any personal/parental device too.
Once your child's device would be successfully registered for SecureTeen software, all collected data/information will appear in provided SecureTeen account. After installation you would be able to remotely control registered device i.e. by alerting different feature's settings on your dashboard. You can access SecureTeen dashboard from anywhere at anytime by using your any personal computer/laptop or cell phone.
