Is it really 7 days free, or is it 37 days for $12.95 instead of 30 days for $12.95? By which I mean they make you enter your card information when you get the 7 days, then 7 days later, they charge you and start doing the monthly thing.
Yes, it is 7 days free trial. After that, you will be charged depending on which plan you chose. 12.95 USD is for the monthly plan. All their plans come with 30-day-money-back guarantee. So if you are charged after the 7-day free trial, you are still eligible for a full refund within 30 days.
