Imagine you'd like to build a database with not only every data you usually can get through user interaction with your service and the device where your app has been installed on, but with pictures of your user's faces, too. What a treasure trove in times of face recognition software.

But surely after all those breaches and hacks related to online services, you'd have a very hard time getting to this kind of data, right? Especially when you are based in Russia?

Wrong.

You grant FaceApp a perpetual, irrevocable, nonexclusive, royalty-free, worldwide, fully-paid, transferable sub-licensable license to use, reproduce, modify, adapt, publish, translate, create derivative works from, distribute, publicly perform and display your User Content and any name, username or likeness provided in connection with your User Content in all media formats and channels now known or later developed, without compensation to you

All you'd need is a fancy app that adds some very good neural networked filters and transformations to uploaded facial pictures, and sure enough, even the tech- and privacy-savvy users can't resist to show off how they may look in some decades, no matter the terms.

Easy as that.

And yes, this is true for any 'social' network or service. Read the privacy statement or terms of Instagram, Twitter and the likes. They all need the agreement to do with the uploaded images whatever they want.
It is just that I am very careful to not have my face plastered all over the web. It is a futile attempt, since attending public events, and sometimes being on stage with my bands, involves pictures, and surely they end up on someone else's computer and in databases owned by the tech giants.
