Davis said that once you put your photo on the app, it can be hard to get it back.
However, experts are warning that this free app poses multiple security concerns, according to the Independent.
According to Forbes, despite the developer company for the app being based in Russian Federation, a security expert who goes by the pseudonym Elliot Alderson (real name Baptiste Robert) downloaded the app and found that the app uses a server based in the U.S.
In a letter to the intelligence agencies, Mr Schumer wrote that the app poses "national security and privacy risks for millions of U.S. citizens" - and presumably citizens of any other country that uses it.
Most social media users will have noticed what looks like the cast of Cocoon appearing on their feeds recently, with over 100 million people turning themselves into their parents with FaceApp's scarily convincing aging filter.
FaceApp clearly states that it can use your photos and information shared on the app for commercial purposes without any royalties.
"FaceApp's location in Russian Federation raises questions regarding how and when the company provides access to the data of USA citizens to third parties, including foreign governments", Schumer wrote to FBI Director Christopher Wray and Federal Trade Commission Chairman Joseph Simons Wednesday night. It is, however, important to note here that FaceApp is hardly the first app to have terms and conditions like this as such language can often be found in other social media apps and websites.
Alderson also noted that the app uses third-party code that uses servers based in the USA and Australia.
The Post reports that they can therefore use your real name, your username or "any likeness provided" in any format without notifying, much less paying, you. He also allayed fears, saying that most of the images in the company's servers are deleted within 48 hours from the upload date.
Lord goes on to say, "It's not clear at this point what the privacy risks are, but what is clear is that the benefits of avoiding the app outweigh the risks".
FaceApp lets users upload their photos and make them look older or younger.
