Today, WhatsApp is preventing MILLIONS of people from viewing your personal information.
Strangers will have a harder time snooping on you thanks to WHATSAPP.
The US chat app began rolling out an update this week that by default prevents people who aren't in your contacts from seeing your "last seen" status.
The timestamp "last seen" appears on your WhatsApp profile and chats to show when you last used the app.
It's possible to hide it in WhatsApp settings, but it was previously visible to everyone.
Following the update, only your contacts and those with whom you've chatted will be able to see your status, keeping your last use of the app hidden from everyone except your contacts.
On Monday, users reported that their "last seen" statuses were no longer appearing on the app, prompting a social media outcry.
"Is there anyone facing the same problem as me i can't see anyone's last seen," one user wrote on Twitter.
The mystery was solved after a different user contacted customer service.
They shared a screenshot of what appeared to be an email from WhatsApp, stating that the app's last seen rules had changed.
"We're making it more difficult for people you don't know and haven't chatted with on WhatsApp to see your last seen and online presence," the email reads.
Users could previously choose whether their last seen information was visible to Everyone, My Contacts, or Nobody.
While your last seen was hidden from everyone, you couldn't see anyone else's timestamp if you chose Nobody.
Previously, WhatsApp's default setting was set to Everyone.
My Contacts is now the default setting.
The change has yet to be confirmed by the company.
WhatsApp has been contacted by The Sun for comment.
In recent weeks, the app has made a number of changes to improve user privacy.
It announced last week that it was expanding its disappearing messages feature, which ensures that messages vanish after a set period of time.
Users can now schedule texts to expire after 24 hours, seven days, or 90 days.
You can now make all of your messages vanish by default.
