# Third-party notices openGym — Copyright (C) 2026 Duarte Santos. openGym's own code is licensed under the **GNU AGPL v3.0** (see [LICENSE](LICENSE)). ## App store exception As an additional permission under section 7 of the AGPL v3.0, the copyright holder permits distribution of the openGym mobile application through app store platforms (such as the Apple App Store and Google Play) whose terms of service would otherwise be incompatible with the AGPL, provided the corresponding source code remains available under the AGPL at the project repository. This permission applies to the distribution channel only and does not otherwise limit the license. ## Body diagram geometry The muscle outlines the body maps are drawn from (`frontend/src/lib/body-paths.js`) are derived from [**MuscleMap**](https://github.com/melihcolpan/MuscleMap) by Melih Colpan, used under the **MIT License** and reproduced below. MuscleMap ships its path data as Swift source rather than `.svg` files; the paths were converted to a JSON module, its sub-group shapes were dropped, and nothing else about the artwork was changed. ``` MIT License Copyright (c) 2026 Melih Colpan Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Neither is covered by openGym's AGPL license. That dataset is itself a redistribution: the content originates from [**ExerciseDB v1**](https://exercisedb.dev/) by **AscendAPI**. This is verifiable from openGym's own data — the stored media filenames embed ExerciseDB's `exerciseId` (openGym's `0001` is `0001-2gPfomN.jpg`; `2gPfomN` is ExerciseDB's id for "3/4 sit-up"), every metadata field matches, and the instruction sentences are identical apart from stripped `Step:N ` prefixes. See [issue #5](https://github.com/hasaneyldrm/exercises-dataset/issues/5) on that dataset. ### Metadata & instruction text The exercise names, attributes and instructions (English in `frontend/src/lib/exercises-data.js`, other languages in `frontend/src/instr/`, regenerated via `scripts/build-instructions.mjs`) originate from ExerciseDB v1 and reach openGym through the dataset above, which distributes them under the MIT license reproduced below. The translations into languages other than English are openGym's own derivative work and are covered by openGym's AGPL. ``` MIT License Copyright (c) 2026 Hasan Emir Yıldırım Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation and data files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Exercise thumbnails and the in-workout motion are original SVG drawings of the MuscleMap geometry (MIT, see above): the target muscle is highlighted and, when “playing”, pulses. That art is part of this fork and may be used commercially with the rest of the AGPL + MIT notices. The optional `media/img` and `media/gif` directories on a host (downloaded by older compose files from hasaneyldrm/exercises-dataset) are **third-party and unresolved** — do not mount or publish them if you sell access.
