The protection of privacy is essential for the development of a healthy social and professional relationship. However, the desire to protect personal privacy can turn into fear of exposing one's personal information to others. The result is that the person feels unable to share their true self with others. This is especially the case with teenagers. They might feel uncomfortable about their bodies and might feel as if they have nothing to talk about with their friends. But, this is simply because they have not yet learned how to protect their privacy.

There are many ways in which one can protect their privacy. One of the most effective ways is to use an application to lock the apps on the phone. The App lock application can lock contacts, SMS, e-mail, gallery, settings, calls, or any apps by password lock.
