@SteMMo Wheter you ask for money or not does not matter. What matters is whether you fulfill the OSS licenses. There are some things many OSS licenses ask you to do: Provide licenses texts in some form, so the user can see which OSS licenses are used Give the user possibility to exchange OSS libraries with own versions (this one can be tricky with embedded boards) If in doubt you should ask a lawyer and/or QtCompany.

@JonB said in Qt License Inquiries: @Braynex said in Qt License Inquiries: I haven't decided yet whether to use Qt (C++) or PySide (Python). Just to remind you of one thing. If you choose Python you must adopt the PySide you mention, either PySide2 or the new PySide6. Don't be tempted to pick the better known/more-featured PyQt5 or PyQt6 you will see around the web, because that requires GPL rather than LGPL. No such issue if you go C++. Hi JonB, noted, thank you for the tips. Our first choice is PySide6 for this project because PyQt's GPL licensing is out of the picture due to the nature of this project. Kind regards, Braynex

@rktech How you write it does not matter. You must observe the LGPL terms of (most of, assuming you stick to that) Qt. Which means that you don't have to publish your sources, and if you do not alter the Qt sources you don't need to publish them either. I am not a lawyer. This is an opinion, not legal advice.

Hi Is that in the Installer this licenses shows or in Creator ? also did you read http://doc.qt.io/qt-5/androidgs.html

@JKSH That's it Thank you guys.
