May I know how you saw that it does because it stands no where on their site. They start charging instantly (which I dont even know if it is legal without any extra confirmation that you have to pay money) and also in there Terms there is nothing that says anything for free.
I mean it surely dont sound so from their site. More like we still charge you even if you given us nothing and we provided no extra information that you have to pay for anything. I luckly realized it before anything was running for me but it does just seem as a very fishy method which restrains me from using it.
I just thought you might have more information than I could find.
I still dont think it is good to advertise something as a developer which uses so unclear and fishy structures especially when you advertise it as a "for free" stuff while it does not say anything about that on the site. All in all not really trustworthy for me to use.
