The 7 day trial without notifications, with no email reminders and no refund policy feel very much like a scam. I cancelled my subscription the day it was set to expire and they have already charged me that same day. I will dispute the charge but BOY are they expensive when there are clearly websites like freecodecamp that offer the same thing for free. WHAT a scam.
Tip for consumers: Do not expect any refunds, they are expensive for the value you're getting and will not refund you even if you cancel the day 7day trial is set to expire.
