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.
The muscle outlines the body maps are drawn from (frontend/src/lib/body-paths.js) are derived
from 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.

The exercise names, instructions (English in frontend/src/lib/exercises-data.js, other
languages in frontend/src/instr/, regenerated via scripts/build-instructions.mjs), images
and animations (fetched into media/ at build time) come from
hasaneyldrm/exercises-dataset
and are not covered by openGym’s AGPL license — they remain under that dataset’s own terms.
The media files are not distributed in this repository; they are downloaded from the upstream
source on first run. If you redistribute openGym with the media included, review the upstream
license first.
