Open-source notices
Split Harbor · web, iOS and Android. Inventory reviewed November 3, 2026.
We thank the authors of the open-source software used by Split Harbor. Their licenses apply to their components; this page does not make KoturStudio’s application code or artwork open source. Versions below describe the reviewed source dependencies and may differ from an installed older beta.
Website, web app and server components
The browser uses PDF.js and QR-code rendering; authentication and server services also use the packages listed below. This includes installed production transitive packages, not just direct dependencies. Development-only build tools are not shipped as app features.

iOS app
The reviewed shipping Xcode app uses KoturStudio Swift code and Apple system frameworks, including SwiftUI, PDFKit, AuthenticationServices, CryptoKit and LocalAuthentication. No separately bundled third-party Swift package was found in its project configuration. Apple frameworks and system software remain subject to Apple’s applicable notices. Shared hosted services use the server components listed above.
Android app
The inventory also identifies third-party provider SDKs, whose linked terms may not be open-source licenses. The native app uses AndroidX / Jetpack Compose, Kotlin libraries, OkHttp/Okio, Firebase Messaging and PDFium Android. Firebase Messaging is used for optional push notifications; Firebase Analytics is not enabled. The resolved release runtime inventory below includes transitive and metadata/constraint entries; shrinking may remove unused code.
