You probably still need to sign up and have a credit card that can be billed. Then it's up to you to cancel and as always these sort of "freebies" want you to forget the actual day to cancel, which is generally more difficult than the sign-up process. And because you've already given credit card info they'll be all set to grab your first payment. Just use this... no commercials. Grab unrooted version and don't bother with the extra work to let you sign in. The app will remember your searches and it'll start up with vids catered to you. No commercials and other tweaks in "vanced" settings.
