Should I buy a license?
-
Hello,
I have been selling and developing the Neyrocode program (http://neyrokod.info) using the QT library since 2011. I didn't buy the QT library. I haven't opened the source code of the program and I'm not going to. I registered the rights to the program here https://www1.fips.ru/fips_servl/fips_servlet?DB=EVM&DocNumber=2018616469&TypeFile=html I would like to clarify whether my activities are legal, and if not, is QT Company able to do anything to me if I am in Russia? -

That's not exactly true. If you use LGPL you don't have to open your source. You need to open only any modifications to the Qt library itself and provide a way to let the user re-link with their own version of Qt. That's usually achieved via shared libraries.

I registered the rights to the program
That's irrelevant for the subject of Qt licensing.
I would like to clarify whether my activities are legal
I am not a lawyer and this is not a legal advice, but probably not at this time. Since you didn't bother to check the license terms there's little hope you're following them by accident. Apart from the requirements I mentioned above there are some other terms you need to meet to use LGPL like distributing a copy of the license with your app.
and if not, is QT Company able to do anything to me if I am in Russia?
Well if you're afraid of that then posting on Qt's forum a link to your website after a decade of illegally distributing your app is not very smart right? That's basically theft, and, as far as I know, Russia does have laws against it like most other countries.
