I'm so happy to announce that finally I can monetize Charts Factory!
I was thinking to change my yearly plan to monthly but I saw that somebody living in USA subscribed for yearly plan.
There were buy me a coffee link before and some people had bought me 4 coffees but that was not monetizing at all :)
It gave me courage to develop more features for Charts Factory and more web apps!
Thank you my first paying customer, whoever you are!
