## About Tellonym

Tellonym is a cross-platform anonymous messaging and social networking app founded in 2016 by three German students.

Developed by Callosum Software GmbH, the app is headquartered in Berlin, Germany, and has grown to approximately 13 million global users, primarily in Germany. Tellonym aims to alleviate social anxiety and foster honest conversations by allowing users to give and receive candid feedback without revealing their identities. The main product is the Tellonym mobile application, available on iOS and Android, along with a web-based interface. Users can send anonymous messages called "Tells" to friends or strangers, which can be replied to and shared publicly on their profiles. The app also includes community features, parental controls, and the ability to share profile links on other social media platforms. Tellonym primarily targets teenagers and young adults seeking honest feedback and connections. The service is free for users and is supported by advertising.
