I have a question about the issue of software licenses, I just finished a program for Android that a small company asked me for, so I am at the point of having to distribute it to them, but first of all I would like to "add" a license to it use, that is, so that they cannot distribute it to third parties, copy it, etc.
I have seen that Google offers the library LVL
for such purpose, but since I don't want to upload the app to the Play Store (since I want to distribute it privately) I don't know if it would be possible to use that library by uploading the app to the Google Play Console without publishing it.
If not, I would appreciate any help/guidance/advice on how to proceed to obtain or create a user license.
