FaceApp came under scrutiny by the Senate minority leader Chuck Schumer, as it alters users’ photos to make them look older or younger.
Mr Schumer called for an investigation on it “deeply troubling” that personal data of the US citizens could go to a “hostile foreign power”, he said in a letter posted on Twitter.
The privacy concerns have also been raised about Russian company, which developed the Faceapp after it went viral in the recent days. Previously, FaceApp has denied the allegations.
A company based in St. Petersburg, Wireless Lab says that it does not permanently store the images, and does not collect the troves of data and only uploading the specific photos that were selected by the users for editing.
A company statement reported by news site TechCrunch said. “Even though the core R&D team is located in Russia, the user data is not transferred to Russia,”
However, Mr Schumer has asked that the FBI and the Federal Trade Commission to investigate the FaceApp matter.
“I have serious concerns regarding both the protection of the data that is being aggregated as well as whether users are aware of who may have access to it,” his letter reads.
