How to make my app unmovable from pc to another

  python, windows

I created an application with python that i will be selling in the next few days, however I don’t want anyone that buys it able to share it with other people as it is paid so everyone that wants the app should pay. i’m not finding a way of doing it, I hope you help me to do so!

can you recommend any tool/framework/method that will help me to achieve this.
I tried to search and wasn’t able to find a good way.

I am using kivy for GUI and made with pure python.
Note: I will compile the app only for PCs and not mobile phones
Thanks in advance.
