BY USING APP

How does this app work? – After you’ve configured the application, the app starts to work. When you open WhatsApp, Not Last Seen app automatically disables your WiFi connection and when you close the WhatsApp window, it automatically starts WiFi. Its accurate and doesn’t keep you waiting. So calling it an automatic WiFi on-off app is justified.

1. Download Whatsapp Online app. We don’t have a Google Play Store link since the app no longer exists there. It violated some Google policies they say.
2. Launch the app. You’ll see three options – Block Last Seen, Block Last Seen at Boot Phone, Always Recover WiFi.
3. Tick ‘Block Last Seen’.
4. Since the app is no longer updated, simply ticking the first one didn’t work for me so I had to tick the second one i.e Block Last Seen at Boot Phone too.
5. If your WiFi connection doesn’t start automatically when you leave the WhatsApp window, tick ‘Always Recover WiFi’.

When the app runs you’ll see a message in your notifications area. You can tap it to change the settings if required or leave it as it is or tap clear to hide it from your notifications bar. I however recommend it to stay there so you’re aware your last seen is hidden.Wait for a few seconds while it scans all your contacts to find out who viewed your WhatsApp profile today. Once it has examined all your contacts, it will show a complete list of all the users who’ve visited your profile on WhatsApp that day. In my case, it only shows a single name. That hit me hard, oh! No one’s stalking me it seems.

MANUALLY

1. Disable your phone’s WiFi or data network.
2. Open WhatsApp. Read messages if any. Send messages if you want to.
3. Close WhatsApp. Enable WiFi or data network.

The messages will be sent as soon as your phone connect’s to the internet without anybody coming to know the last time you accessed WhatsApp! The last seen they’ll see will be the time you last opened WhatsApp with your internet connection on.
