Koo app said that sensitive user data allegedly leaked from the social network are details that users have voluntarily shared on their profiles. “It cannot be termed a data leak. If you visit a user profile you can see it anyway,” Koo app’s founder and CEO Aprameya Radhakrishna tweeted. Koo, recently, had introduced email logins which have been ‘blocked from view’ after concerns. This has come after data leak allegations by French hacker having pseudo name Elliot Alderson.
