Privacy experts are raising concerns about an app that computer-ages your face.
Drake and Stephen Colbert have boosted the popularity of the ``FaceApp Challenge.''
The app, which was launched by a Russian company two years ago, has terms of use that include granting the rights to reproduce, modify, publish and share photos and other user content with third parties.
FaceApp now says it only uploads photos to the cloud that users have selected, and that anyone who doesn't want identifying information shared can bypass signing in.
