Honest summary before we start. Klin OS is a private, internal operating system of Klin Arts and Entertainment Ltd., used exclusively by Caio Klinger himself to manage his artistic company. There is no public sign-up, no sale of services to third parties, no external user. These Terms exist because platforms such as TikTok for Developers, Spotify for Developers and others formally require them to authorize use of their APIs, even for internal use. This document also covers any internal collaborator who may eventually access the system.
