logga

Third-party licences

logga bundles open-source components. This page lists them and their licences. Every component has been audited for commercial-use compatibility, and the attribution required by each licence is given in full below.

Last updated: July 2026

logga is built on the shoulders of an excellent open-source ecosystem. If you want to know what these components send over the network (in short: the models are downloaded once, then everything runs on your Mac), see the privacy proof.

Frontend dependencies

Bundled fonts

Both fonts are self-hosted as unmodified woff2 subsets.

Python dependencies (speaker-ID sidecar)

These ship inside the compiled speaker engine published on the public binaries-only repo (github.com/dsmih/logga-releases) and downloaded by the app on first run.

  • pyannote.audio v4.x · MIT · CNRS / pyannote.ai
  • PyTorch (incl. torchaudio) · BSD-3-Clause · Meta Platforms, Inc.
  • python-soundfile · BSD-3-Clause · Bastian Bechtold
  • libsndfile · LGPL-2.1 (dynamic linking) · Erik de Castro Lopo and contributors

pyannote.audio 4.x no longer depends on SpeechBrain; it is not shipped.

ML models

These are the models logga downloads on first run, SHA-256 verified. The privacy proof covers exactly when and where that download happens.

CC-BY-4.0 attribution notice

The following models are used under the Creative Commons Attribution 4.0 International License.

pyannote/speaker-diarization-community-1

  • Created by: Herve Bredin and pyannote.ai contributors
  • Source: huggingface.co/pyannote/speaker-diarization-community-1
  • Licence: CC-BY-4.0
  • Usage: Model weights redistributed in the speaker-engine bundle (planned pipeline upgrade; the runtime currently loads speaker-diarization-3.1)
  • Modifications: None. Original model weights redistributed unmodified.

wespeaker VoxCeleb ResNet34-LM Embedding Model

  • Created by: WeNet/WeSpeaker contributors
  • Source: github.com/wenet-e2e/wespeaker
  • Licence: CC-BY-4.0
  • Usage: Speaker embedding extraction for diarisation (pyannote pipeline and sherpa-onnx fallback)
  • Modifications: None. Original model weights used unmodified.

Licence compliance measures

  1. Attribution. Third-party components are credited on this page and in the THIRD_PARTY_LICENSES file distributed with the application source, included in the app bundle as a resource, and mirrored in the README of the public binary-releases repo (github.com/dsmih/logga-releases) for the redistributed sidecar components.
  2. Licence texts. Full MIT, Apache-2.0 and BSD-3-Clause licence texts are preserved in the source tree via Cargo and npm package metadata, and summarised below.
  3. Gated HuggingFace models. The developer accepted the pyannote model terms on huggingface.co. The weights are redistributed as a HuggingFace cache folder alongside the sidecar binary inside the speaker-engine archive, so end users do not need HuggingFace accounts or tokens.
  4. CC-BY-4.0 attribution. Visible credit is provided on this page, in the bundled licences file, and in the README of the public releases repo that carries the weights.
  5. Commercial compatibility verified. All components permit commercial use. The only LLM logga ships is Phi-3.5-mini-instruct (MIT).
  6. Copyleft inventory. One LGPL-2.1 component ships: libsndfile, bundled unmodified inside the speaker engine as a dynamically loaded library (_soundfile_data/libsndfile_arm64.dylib, loaded at runtime by python-soundfile). LGPL-2.1 permits closed-source use via dynamic linking, and the library can be swapped for a user-built copy by replacing that dylib. No GPL or AGPL components are used, and nothing requires logga's source code to be released.
