See this is scary. As soon as I read this, I deleted the app. Not like it may matter considering I did do the Age Challenge.
Basically the FaceApp is created by Wireless Lab in St. Petersburg Russia. And now there are reports that sugges that it gives developers, and possibly even hackers access to your personal information. The apps terms and conditions allegedly state that they have the right to modify, reproduce, and publish the images you create through their app.
Well that sucks!
