Mohamed, I had the same question. After looking at the Screpy website I found this, so I figured I'd share it here with you. Just look at this and hopefully it will provide the info you were looking for. https://support.screpy.com/hc/user-guide/articles/1751481179-all-new-screpy-credits Good luck. Gary Gordon

For each tier you can see that it says “Monthly credits” which means they give you that that number of credits every month, but they don’t roll over if they are unused. Does that make sense?
