Over the summer, social media platforms were inundated with images of just about everyone you know looking unusually old or like an attractive member of the opposite sex. This was all thanks to an extremely popular smartphone application called “FaceApp.”

Despite first being launched in 2017, the app became a massive hit in recent months, spending a fair amount of time in the top spot in lists of free applications for both Apple and Android devices. However, despite the good time seemingly being had by all, it wasn’t long before people started asking hard questions about how data transmitted through FaceApp was being stored… and what it could eventually be used for.

FaceApp, it turned out, is a Russian developed and based application. This means that every image you uploaded into the facial recognition software could have been relayed to Russian servers before being sent back to your phone with some added wrinkles. The terms of service that came with the application did little to assuage concerns that the images could find a permanent home in Russian hard drives for use in whatever they are deemed fit.

If you aren’t particularly concerned about Ivan hanging on to  your selfies, you should know that the app worked by recording biometric data about you (the specifics of your facial structure); and that the terms of service you agree to when using the app also allow the company (or other Russian affiliates) to use your likeness, username, and even real name for commercial purposes.
