Windows portable version?

I don't wanna install your app or somehow integrate it to OS. And I don't want make any registry traces or system user folders traces.

Just ZIP/7Z-file — unpack it and launch EXE-file.

A valid request. It appears we could publish portable executables (PyInstaller's --onedir one-folder bundle) by inserting the appropriate zip and actions/upload-artifact commands in between here: https://github.com/efck-chat-keyboard/efck/blob/096a7b6cc4004911c06337fa736a25ac67e1e628/.github/workflows/ci.yml#L159-L160

Alternatively, you could use a tool such as innoextract or innounp to unpack and extract the existing installer contents, which then you should be able to run how you expect.

make any registry traces or system user folders traces.

Upon user configuration change, the software may write a config file into a well-known directory. Behavior to the contrary is out-of-scope.
