Hi there!
Thanks so much for following up! 12 update cycles would be for things like site crawl data. Rankings would not be collected while your Campaign is archived but we would keep your historical data.
If you would like to cancel your subscription, you can do so at any time from your subscriptions page: https://moz.com/subscriptions
I also have a guide from our Help Hub that can help: https://moz.com/help/your-account/manage-subscriptions/cancel-moz-pro
Hope this helps!
