Ever wanted to know how you'll age? There's an app for that.
Launched in 2017, FaceApp isn't necessarily new. But it's making headlines again because the app has gotten good -- like, eerily good -- at showing users what they'll look like when they age.
It's scary, so use at your own risk. Or, take a spin through Twitter or Instagram to see how others have turned out years into the future.
Basketball star Dwyane Wade gave it a go -- or, in this case, retired basketball star?
Tottenham Hotspurs, a soccer team in England, made a whole Twitter thread of their players with FaceApp. It's amazing.
And rapper Drake got in on the aging action (though it isn't clear if he used FaceApp to do it).
The app uses neural networks -- a type of artificial intelligence -- to edit the photos.
And it can do more than just age you. The app can literally put a smile on your face, make you look younger, or swap your gender, too.
The app, though enjoyable, is also resurfacing concerns about security and privacy. FaceApp is owned by Russian tech company Wireless Labs, who has been scrutinized in the past for how the photos uploaded to the app are used.
David Vaile, a privacy expert and and executive director of the Cyberspace Law and Policy Community at the University of New South Wales, spoke about the concerns in April 2017.
"Short answer: don't use it," Vaile told the Australian Broadcasting Corporation in 2017.
Vaile added: "They ask for way more rights than they need to offer the service to you, (they) can remove the data from any effective legal protection regime, share it with almost anyone, and retain it indefinitely.
"It is impossible to tell from this what happens when you upload it, that is the problem. The (license) is so lax. They can claim you agree they can send to wherever they like to whoever they like, and so long as there is some connection, (they can) do a lot of things with it."
This means the app collects information about your browsing history and location.
"We will not rent or sell your information to third parties outside FaceApp," the policy also says. But it adds: "We may also share certain information such as cookie data with third-party advertising partners."
FaceApp CEO Yaroslav Goncharov hasn't responded to questions about the app's use of data and information in regards to users' privacy and security.
