This app lets you protect your WhatsApp's privacy through a PIN.
After installation it will ask you to set a 4 digit PIN, and will show the configuration options.
You can customize auto-lock time, so you don't need to enter the PIN every time you change task on your device.
If you enter a wrong pin and your phone has front camera, it will take a picture of the intruder and saved in the photo gallery.
Have fun in detecting the intruder! (Only devices with front camera)
