it's the closest, but it's a very broad and not so well known term, maybe defining my app open source is not technically a perfect term, but it's the clearest in describing it (considering that in the libraries and models section I specified which are open-source and which are not, Ml-Kit, used to recognize the language, for example is closed source), if a developer doesn't see the open source writing anywhere he will only get confused in understanding what the license of my app is. However, based on your feedback I added the specification (in the "libraries and models" section) that NLLB has a non-commercial license.
