Those that have used social media in any capacity this week likely have seen the new “old” filter in FaceApp that ages (almost) any picture to show what that person would look like much older. FaceApp is by no means a new app but its popularity has likely skyrocketed thanks to the proliferation of these “old face” filter photos.

However, those mobile users who want to get in on the FaceApp old age filter fun should be careful, as using the app comes with a big catch. In the app’s Terms of Service, there is a section that gives the app and its developer, Wireless Lab, a license to use any images created with the app.

It’s a fairly standard section of the Terms of Service in a social media-based app – Twitter has a similar line in its TOS – but it’s worth highlighting all the same. Users may be quick to download FaceApp and try out the old age filter without realizing what they are doing. Others may not care, but at least they should be aware.

Instances of an app or service actually using a patron's media for monetary gain are few and far between, but in today’s digital age it’s always important to be cautious about putting your likeness out there, regardless of if it’s using an old age filter. FaceApp essentially owns the rights to any picture that you take with the app and they can even modify it.

FaceApp has been around since 2017 and had its share of ebbs and flows when it comes to popularity. Not long ago the app was in the news thanks to a filter that showed users as the opposite sex. It wasn’t a new concept that FaceApp was trying but the realism of the filter is what made it so popular.

Now the old age filter is having the same effect, by adding wrinkles and greying the hair of users. Not every use of the filter is perfect but it’s actually quite scary seeing what you might look like in 20+ years.

Still, users should be careful what images they upload and how they use the FaceApp app in general.
