Third-Party Components and Open-Source Licenses

Updated: October 19, 2026 · Applies to: the Wenyin macOS app and the Wenyin website · Document version: v1

Wenyin is independently developed and operated by an individual developer. Contact: songsong24@foxmail.com.

Wenyin is commercial closed-source software, but the installer and this website include third-party open-source components. This page lists, component by component, where each comes from, where it is used, and which license it follows. The complete license texts are provided unmodified as plain-text files.

Detection limits: automatic detection can miss or misidentify items. Third-party license notices do not change that; review each detection result and check every exported file.

1. Components shipped with the app

The complete text is identical to 文隐.app/Contents/Resources/ThirdPartyNotices.txt in the app installer, about 6,500 lines in total.

2. Fonts used on this website

All serif fonts on this website are self-hosted subsets, packaged separately by language. Each page downloads only the two files its language needs and calls no third-party font service. The font files are subsetted products; the font family name is uniformly changed to Wenyin Serif, and no derivative font is released under any reserved font name.

LanguageFont and filesLicense
Simplified Chinese Source Han Serif subsethero-assets/fonts/wenyin-serif-hans-regular.woff, hero-assets/serif-cn-SemiBold.otf SIL OFL 1.1SOURCE-HAN-OFL.txt
Traditional Chinese Source Han Serif subsethero-assets/fonts/wenyin-serif-hant-regular.woff, hero-assets/fonts/wenyin-serif-hant-semibold.woff SIL OFL 1.1SOURCE-HAN-OFL.txt
English Tinos subset by Steve Matteson / Tinos Project Authorshero-assets/fonts/wenyin-serif-latin-regular.woff, hero-assets/fonts/wenyin-serif-latin-semibold.woff; if the device has Times New Roman installed, the local font is preferred and nothing is downloaded SIL OFL 1.1TINOS-OFL.txt
Japanese Noto Serif JP subsethero-assets/fonts/wenyin-serif-ja-regular.woff, hero-assets/fonts/wenyin-serif-ja-semibold.woff SIL OFL 1.1NOTO-SERIF-JP-OFL.txt
Korean Noto Serif KR subsethero-assets/fonts/wenyin-serif-ko-regular.woff, hero-assets/fonts/wenyin-serif-ko-semibold.woff SIL OFL 1.1NOTO-SERIF-KR-OFL.txt

Body text, navigation, and tables use each system's interface font stack and download no font files; code and file paths use a monospace stack. Copyright in Source Han Serif, Tinos, and Noto Serif belongs to their respective authors; SIL OFL 1.1 requires retaining the copyright notice and license text, which this website does, and no font is sold separately.

3. macOS system components

The interface, document preview, PDF handling, and Finder extension use system frameworks provided by macOS (for example SwiftUI, AppKit, PDFKit, Quick Look, and system fonts). These frameworks ship with macOS itself, are not distributed separately with the Wenyin installer, and are subject to Apple's software license terms.

4. Complete license texts

The complete text is provided unmodified, neither translated nor edited, and includes all notices for Sparkle, ONNX Runtime, and the third-party components bundled with ONNX Runtime:

third-party-notices.txtPlain text · about 345 KB · identical word for word to the file in the installer

5. Licensing questions
