Add a trial version for my bot

Hi just a question does anyone here have an idea how to integrate this on Ctrader.

On C# I've found resources for making a trial version for your app but I think it's done with .exe files when I checked ctrader files the code for bots and indicators are converted to .calgo files.

This are the things I'm planning to do

1.) send the bot (without source code to a user)  - can be done just by sending the .calgo file do I need to encrypt? etc.

2.) have the ability to turn it off and prevent the user from using it whenever we want to, like a trial version for the bot

Thanks
