Want to know what you'll look like when you're older? There's an app for that.
It's called FaceApp. The app uses neural networks -- a type of artificial intelligence -- to edit the photos. And it can do more than just age you. You can also use the app to put a smile on your face, make you look younger, or swap your gender.
Even celebs are getting in on the action. There are photos of Carrie Underwood and Mike Fisher, as well as Terry Crews, Sam Smith and Dwayne Wade.
FaceApp was developed by a small team in Russia and has been around since 2017. Its popularity is rising again because its aging game is on point.
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.
According to the policy, the app "cannot ensure the security of any information you transmit to FaceApp or guarantee that information on the service may not be accessed, disclosed, altered, or destroyed."
