How to lock your WhatsApp on your Android

Ever gave a friend your phone to do something on it and you found out (s)he is busy looking for something else? Like checking into your conversations in your messaging apps like WhatsApp, BBM, Hangouts. I have tons of conversations I won’t want anybody else to see; not because I’m hiding anything bad but I value and cherish my privacy. A friend once asked me how she could lock her gallery app and others. She was like; “I have some private files I wouldn’t want anybody I give my phone to see.” I guess I should just let everyone know the simple apps that could render the simple help.

1. Messenger and Chat Lock


This app lets you protect your messages from WhatsApp, BBM, WeChat, Telegram, Viber, LINE, Hangouts, GTalk, Facebook, SMS, Kakao Talk, Kik Messenger, Tango, SnapChat, Twitter, Instagram, Tinder, MeetMe, Skype and Yahoo Messenger behind a PIN. Keep you privacy and maintain secure!
You can also configure it to protect your images and videos from your device gallery.

After installation it will ask you to set a 4 digit PIN, and will show the configuration options to lock these apps.
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 save it inside the application.

Have fun in detecting the intruder! (Only devices with front camera)
