Welcome to the Roku Community, @drkbrf!
Thanks for reaching out. We'd be happy to share further information about this.
Please be informed that turning off auto-renew via the Roku website cancels your subscription, and you will not be billed for it in the future. After canceling your subscription, you'll continue to have access to it until the end of your current billing cycle.
You may check our support article related to this for more information: How to turn off auto-renew and cancel a subscription
We hope you find this information helpful.
Best regards,
Carly
