Hi Guys,

1. Hide Contacts, Call Logs, Messages & any files or Folders
2. Multi-select to delete calls, both hidden calls and system calls
3. Hide your Secret Photos/Videos
4. Hide your Secret Data
5. Lock any App in your Phone, even facebook, twitter & whatsapp
6. Secure your data with double protection!
7. Different Lock Modes
8. Double Door Protection

The App is currently, i have not lunched because it is under testing process. I need your suggestions regarding the App so that I can add the some more functionality to the app.

Thanks in advance,
