You can see the subscriptions you have through Roku on your account at https://my.roku.com . Note that any subscriptions you have directly with a provider (e.g., Netflix) won't show up there. If you have more than one Roku device make sure they're all linked to the same Roku account by checking the email address on each one displayed under Settings->System->About. It's not uncommon for people to inadvertently create a new account when getting a new Roku device.
