How to Hide “Last Seen” in WhatsApp
By default, WhatsApp sets your privacy settings to allow all other users to see your read receipts, last seen, about section and profile photo, and for your contacts to receive your status updates.
To change these settings,watch the video or follow these steps:
On an iPhone – launch Whatsapp and then tap on : more then tap Settings, located at the bottom right. Tap Account, then Privacy. There you have the option to change your last seen status from Everyone to Contacts (so it’ll only be visible to your WhatsApp contacts) or to Nobody.
On Android – launch WhatsApp and tap the Menu Button then Settings. In this menu, tap Account, then Privacy. The option to hide your last seen status can be found here.
On a Windows phone – launch WhatsApp, then tap More (the symbol with three dots). From there tap Settings, then Account. Tap Privacy, where you’ll find the same options mentioned above.
Note:
If you don’t share your last seen, you won’t be able to see other users’ last seen.
