What a cool trade-free software. Trade-free, because it doesn’t want anything from you like data, attention (ads) or currency. And cool, because of the many features it provides. I remember even my teacher in school showed us that program. However, on the website, google analytics is used, which, of course, collects data about the visitors. That’s why I give 4/5 blocks.
