Obscura Catalog ships the third-party component below, which remains under its own license. It also depends on ObscuraKit, by Oorun, whose only third-party component is Sparkle.
Sparkle 2.10.0
Built-in updates use Sparkle (https://github.com/sparkle-project/Sparkle), brought by ObscuraKit’s ObscuraUpdates module and copied into the app (Contents/Frameworks/Sparkle.framework). Sparkle is distributed under the MIT license, reproduced here:

macOS frameworks
Otherwise, Obscura Catalog and ObscuraKit use only the frameworks provided by macOS, under the Apple SDK license agreement: Foundation, SwiftUI, AppKit, CoreGraphics, ImageIO, Vision, PDFKit, CryptoKit, Security, and the system’s SQLite library. SQLite is in the public domain (https://sqlite.org/copyright.html).
Inter
The Inter typeface (SIL Open Font License 1.1, https://github.com/rsms/inter) is not shipped in the app: it is only used for the brand kit and this website.
Any third-party component added to the app will be listed here, with its license.
