I am about to sell a module that I coded for e-commerce websites, and I was wondering if it's possible, to insert some extra code in it in order to know which websites are running the module. In other words, let's say a customer buys my module, then install it on its website, is there a way for me to know which website it is ?
I don't want any other info than "which website", my goal is not to trace users, but simply to have a statistic of the number of websites where my module is installed (because, it can be for instance that a customer buy the module then install it on several other websites...)
Thanks for your help
