Third-party notices — OSGKeyboard

OSGKeyboard itself is source-available under the repository LICENSE; it is not an open-source or MIT-licensed application. The notices below apply only to the named third-party components or explicitly identified data subsets.

The generated Chinese source manifest is OSGKeyboard/Resources/Typing/Rime/manifest.json. Exact librime binary dependency licenses are bundled beside NOTICE.txt.

OSG-owned pieces

• SwiftUI QWERTY / candidate UI, RimeEngineBridging, and the English suggestion / autocorrect / next-word session layer.
• Objective-C++ C-API bridge for librime.
• Full-pinyin, Microsoft-double-pinyin and Sogou-double-pinyin schemas.
• Microsoft/Sogou mappings were independently encoded from public key-map specifications; GPL schema files were not copied.
• Eight opt-in fuzzy-pinyin rule groups.
• Project-curated bilingual AI/technology speech phrases under Scripts/lexicon/seeds/ai_tech_brands_seed.tsv. This data subset and its generated CLM phrase list are MIT-licensed; that grant does not change the source-available license of the app.
• Offline English typing data under OSGKeyboardShared/Resources/Typing/English/:
  • english_lexicon.bin — mmap-friendly binary of the top 40k alphabetic unigrams (log-scaled ranks) plus truncated bigrams; this is what the keyboard extension loads
  • english_lexicon.tsv / english_bigrams.tsv — build inputs derived from Peter Norvig’s public-domain count_1w.txt / count_2w.txt (https://norvig.com/ngrams/; not GPL/LGPL dictionaries). Not copied into the app bundle.
  • Rebuild with python3 Scripts/typing/build_english_lexicon.py (add --from-tsv to compile the binary from existing TSV without network)

macOS local speech stack

Component	Pinned version	License	Purpose
mlx-audio-swift	d302a5c…	MIT	Qwen3 streaming ASR integration
mlx-swift	0.31.3	MIT	Apple MLX tensor runtime
mlx-swift-lm	3.31.3	MIT	MLX model utilities
swift-transformers	1.1.9	Apache-2.0	Tokenizer and model utilities
swift-huggingface	0.8.1	Apache-2.0	Model download client
Qwen3-ASR 0.6B / 1.7B MLX 4-bit	Runtime download	Apache-2.0	Optional on-device speech-model weights

The Qwen models are downloaded only after the user selects a local model on macOS. They are not committed to this repository. Their model cards identify the original Qwen3-ASR model and the mlx-community conversion.
