Optional FFmpeg is an external shared-library sidecar only. ### Steamworks SDK (Steam build only) `steamworks.js` (MIT, https://github.com/ceifa/steamworks.js) is a native binding used to call the Valve Steamworks API (achievements, rich presence, etc.) from the Electron main process. The binding code itself is MIT, but it wraps the **Valve Steamworks SDK**, which is not open source: distributing a product that links the SDK requires the developer to be a registered Steamworks partner under Valve's [SDK Access Agreement](https://partner.steamgames.com/documentation/sdk_access_agreement) (a nonexclusive, royalty-free, terminable license to reproduce and redistribute the SDK's `redistributable_bin` binaries, granted only to signed partners — not a generally redistributable open license). This product is built and published through a registered Steamworks partner account; the SDK Access Agreement terms apply to that distribution, separate from the MIT terms on the JS binding layer. Steam-specific integration is **not** present in non-Steam builds of this product. The cursor-buddy overlay uses three.js plus React Three Fiber and @react-three/drei (all MIT). Three.js `examples/jsm` loaders such as GLTFLoader, and the `examples/jsm/environments/RoomEnvironment` used to light PBR buddy skins, are the same MIT license as three — no separate attribution needed. **gltfjsx** is a local CLI (`npm run buddy:gltfjsx`) for inspecting bundled GLBs during development and is **not** included in the Steam / Electron package. ### Cursor buddy characters A cursor-buddy 3D character "pig" (`public/buddy/glb/pig.glb`) is bundled as of 2026-08-24 — a different file from the earlier Meshy-generated "pig" (bundled 2026-08-23–2026-08-24, removed the same day). **This new file's provenance has not yet been documented** — see `legal/MESHY-ASSET-NOTICE.md` for the pending-confirmation notice; fill in the actual creation method (self-modeled, AI tool, commission, etc.) there before commercial distribution. The earlier Meshy 3D golden hamster and its clip GLBs were removed and are **not** shipped. There is no user 3D import. ### MediaPipe Tasks Vision (optional camera buddy) `@mediapipe/tasks-vision` 0.10.21 (Apache-2.0) runs **on this PC only** when the cursor buddy is in camera mode. WASM ships in `mediapipe/wasm/`. Pose and face landmarker `.task` files are downloaded on first use from Google’s MediaPipe model host and are not uploaded with user video. Faces never leave the device. ### Pinned model revisions (모델 리비전 고정) Optional on-device models are downloaded from Hugging Face at a fixed commit, so a shipped build cannot silently pick up different weights or a changed license from the repository's `main` branch. Licenses verified 2026-08-12. | Model | Repository | Pinned commit | License | | --- | --- | --- | --- | | Whisper tiny (auto captions) | Xenova/whisper-tiny | 5332fcc35e32a33b86612b9a57a89be7906102b1 | Apache-2.0 (OpenAI weights MIT) | | BEN2 (background removal) | onnx-community/BEN2-ONNX | c552aa82688edce09f0ac9d2e31ad53d9d629010 | MIT (upstream PramaLLC/BEN2 also MIT) | | SAM 2 hiera-tiny (object cutout) | SharpAI/sam2-hiera-tiny-onnx | 2b467a10bfd7d49ba5fe6a00fbee4351f0b1a739 | Apache-2.0 (Hub field `license: apache-2.0`, 2026-08-15; upstream facebookresearch/sam2) | FFmpeg.wasm / `@ffmpeg/core` is **not** used. WebM export still uses WebCodecs VP9 + Opus muxed by Mediabunny (MPL-2.0). MP4 export uses an **external FFmpeg process** (shared libraries, never statically linked) with hardware H.264 encoders or Cisco OpenH264, plus FFmpeg’s built-in AAC. See `build/ffmpeg-build-notes.md` and `legal/THIRD_PARTY_NOTICES.md`. Legacy user-owned MP4 sources remain readable through browser/OS decoders. The WebM Project offers VP9 and Opus under open/no-charge terms and publishes patent grants. As its official FAQ notes, no open codec can guarantee that an unaffiliated third party will never assert a patent claim. This product does not represent that patent risk is literally zero. Hardware H.264 (NVENC / Quick Sync / AMF) is invoked through vendor drivers already on the user’s PC. This product does not bundle those drivers. H.264/AVC patent-licensing obligations may vary by the user’s environment. This software follows common industry practice of using encoders provided by the OS and hardware. This is not a representation that patent risk is zero, and it is not legal advice. Cisco’s BINARY_LICENSE MPEG-LA language applies only to Cisco’s official OpenH264 binary, not to hardware encode. For export mixes, audio is decoded with the Web Audio API when practical. Large video files may demux their audio track via Mediabunny (same MPL-2.0 dependency already listed above) before mixing. Voice tone presets (cinematic / podcast / radio) use only the Web Audio API (BiquadFilter, DynamicsCompressor, Delay, Convolver) with **first-party synthetic impulse responses** generated at runtime. No third-party measured IR libraries (OpenAIR, commercial IR packs, etc.) are bundled. Image enter/exit motion sound effects (whoosh / pop / thud / softClick) are **first-party procedural PCM** synthesized at runtime with the Web Audio API (deterministic PRNG + oscillators / filtered noise). No third-party SFX sample packs or recorded libraries are bundled. These sounds may be used in exported videos for commercial purposes along with this product. Automatic captions use **OpenAI Whisper** original model weights (MIT, Copyright (c) 2022 OpenAI) via the **Xenova/whisper-tiny** ONNX conversion (currently marked Apache-2.0 on its model card), **Transformers.js** (Apache-2.0), and **ONNX Runtime Web** (Microsoft MIT). Inference runs locally. Model weights may be downloaded once from Hugging Face and cached in the browser; the ORT WASM runtime is copied into `public/ort/` at build time so remote executable code is not fetched at runtime. This product does **not** call the paid OpenAI API for captions and does not upload user audio to developer servers. Keep the MIT copyright notice when redistributing Whisper-related materials. **Background removal** uses **BEN2** (Background Erase Network) ONNX weights via Transformers.js (`onnx-community/BEN2-ONNX`, MIT on the Hub card; upstream open Base `PramaLLC/BEN2`). Inference runs locally; images are not uploaded to developer servers. Model weights may download once from Hugging Face and cache in the browser; ORT WASM stays bundled under `ort/`. This product does **not** use BRIA RMBG (which requires a separate commercial license for commercial products) and does not ship Prama’s separate paid commercial tier beyond the open MIT Base weights. Keep the MIT notice when redistributing BEN2-related materials. Noise reduction (“잡음 줄이기”) is **first-party spectral processing** (STFT + quiet-frame noise-floor estimate + soft spectral subtraction) written for this product and run in a local Web Worker. It does **not** bundle RNNoise, DeepFilterNet, or any third-party neural/ML weights. **Pixabay stock search** is optional. Searches are user-initiated and are relayed through the developer's backend service, which holds the application's approved Pixabay API access; no Pixabay key ships in the app. Imported media is downloaded to local IndexedDB (no permanent hotlinking). Attribution is shown in the UI. Users remain responsible for the Pixabay Content License and API terms. Pixabay content is **not** redistributed inside the app package. **Auto captions, background removal, and object pick** run on-device. Whisper / BEN2 / SAM 2 weights download from Hugging Face on first use; inference stays on this PC. **Cloud AI features** (image/sticker/scene-plate generation, scene captions, translation, pronunciation review, and TTS narration) are optional, consume prepaid AI credits purchased through Steam, and are served by Google's Gemini API via the developer's backend. The app never embeds a Google API key and never calls Google directly; only the content you submit for a request is sent. Google's Generative AI terms apply to generated output. Voice cloning is not implemented (preset voices only). The ElevenLabs API is not used. ### Apache-2.0 build modification notice The production build removes remote ORT CDN defaults from Transformers.js / ONNX Runtime integration and points the runtime to the app-bundled local `ort/` files ships with the app so model runtimes stay local. The complete Apache License 2.0 is distributed as `legal/APACHE-2.0.txt`. ### MPL-2.0 source availability notice (Mediabunny) Mediabunny is licensed under the Mozilla Public License 2.0. This product uses Mediabunny in unmodified form.

Conditions Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1. 3. Responsibilities ------------------- 3.1. Distribution of Source Form All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients' rights in the Source Code Form. 3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then: (a) such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and (b) You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation --------------------------------------------------- If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination -------------- 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. ************************************************************************ * * * 6.

Versions of the License --------------------------- 10.1. New Versions Mozilla Foundation is the license steward. Except as provided in Section 10.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number. 10.2. Effect of New Versions You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, or under the terms of any subsequent version published by the license steward. 10.3. Modified Versions If you create software not governed by this License, and you want to create a new license for such software, you may create and use a modified version of this License if you rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License). 10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this version of the License, the notice described in Exhibit B of this License must be attached.
