Making a website where to download my App, copyright? license?
-
Hello everybody. I'm developing an application for Raspberry Pi but it is cross-platform too (Windows and MacOS).
I would like to make a website where people can download this application to start to test it and make the firsts bug reports and to start to divulgate my new app.
Since I don't want to release my source code, should I pay the Qt license first?
And to protect my application, should I request a copyright?Thanks you.

@Giridhar Depends on the components. What are your dependencies, code-wise?
Some Qt modules are on GPL, which is a viral license.
Most commonly used, I believe, is on LPGL - as long as you adhere to this license requirements, you can hold on to your codebase.
And then there is a question of external dependencies and their licenses. -
As I understood, GPL and LGPL don't let me to hold my codebase, by the way, these are the module added inside my .pro file:
core
widgets
gui sql
serialport
network
qml quickI'm using widgets and qml modules because I still have some old .ui file that will be converted to qml. As external dependencies I will use the KDAB's "KDDockWidgets".
But what about to don't let other user to steal my idea and don't let them to make a copy of my app? Copyright right? 😂
After all, when I need the Qt license? Maybe when I should use my app to make profit?Founder & Developer of: https://pidmx.net

Some Qt modules are exclusively available under paid license only. Others under free licenses.
I think it might be of value for you to consult a lawyer with expertise covering IP/software licensing.

On the personal note - ideas can't be stolen. The worst that can happen is that someone does better implementation than you can.
