OSM maps do not require a license, as far as I know, that is their purpose and in their name (OS - Open Source)

Is it possible to crc*k the app and how much work does it require, only a serious programmer who needs to take a lot of time to analyze it can say. That's a lot of work and rime.

You cannot demand such a thing from anyone, you can ask in general. If someone has the will and time they will respond.

Otherwise, only the authors of the application can make it for Android 15, no modder can do that

I'll move this short discussion to the appropriate section later

Edit:

The app is not specially designed for Pakistan. It's actually Ukrainian.
Some people have already tried to process it. A serial number is required to log in to the server, and it's very difficult to do anything there.
