Kik Messenger, commonly called Kik, is a freeware instant messaging mobile app from the Canadian company Kik Interactive, available free of charge on iOS and Android operating systems. It uses a smartphone's data plan or Wi-Fi to transmit and receive messages, photos, videos, sketches, mobile web pages, and other content after users register a username. Kik is known for its features preserving users' anonymity, such as allowing users to register without the need to provide a telephone number or valid email address. However, the application does not employ end-to-end encryption, and the company also logs user IP addresses, which could be used to determine the user's ISP and approximate location. This information, as well as "reported" conversations are regularly surrendered upon request by law enforcement organizations, sometimes without the need for a court order.
