Can LibreOffice be used for commercial basis without distribution?

Always thank for your effort in LibreOffice.
I’d like to use LibreOffice for commercial product in Mobile Application.
But I hope sell my office sutie for Mobile without distribution of source code.
Donation or Join in communinity is okay for me.
Please let me know how to do it.


Maybe here:

you can find some answers.

This may technically contain the answer, but I’m not seeing it in the license, which seems to be mostly about contributing source code and distribution, and like most licenses is written in lawyer language. Which paragraph says we can or can’t use LibreOffice in a corporate environment or under what restrictions?
