It's been quite some time that Android and iOS users are enjoying the calling feature on WhtsApp. The voice calling has been rolled out to BlackBerry 10, and now rumours suggest that the feature will soon hit Windows Phone users as well.

While the cross-platform app enables you to exchange messages, there are few important things concerning the security and privacy, users need to be aware of.

Following is a list of tips to enhance the privacy settings for your WhatsApp. These are applicable for all users regardless of the operating system the device is running on such as Android, iOS and Windows.

Hide WhatsApp images from Gallery/Photos

When you send or, receive photos in WhatsApp to anyone, the photos get saved in a folder on your memory: internal storage or, SD card. And anyone who goes to your Gallery/Photos app can view them. Check out the following steps if you want to hide your WhatsApp images.

  • Download a file manager app such as ES File Manager or, Cabinet Beta
  • Navigate to WhatsApp/Media/WhatsApp Images directory on the phone
  • Create a new file name .nomedia and save it

By doing so, your WhatsApp images will not show up any more in your Gallery/Photos app.

Lock WhatsApp

You can also lock your WhatsApp if you don't want others to access it. WhatsApp does not provide any such functionality to lock the app, but you can always use third party apps. If you are using an Android phone, you can lock WhatsApp with FingerSecurity or, any other locking app available in the Google Play Store such as AppLock, LOCX.

Hide 'Last seen' time

Disabling the Last seen time stamp is helpful for those who do not want others to know how often they are online on WhtsApp or, when is the last time they used it. Below are the steps to disable it.
