What if the user does not want to change the subscription but simply woud prefer to manually approve a renewal?

What would happen if they dont then? Just thinking out loud here as there is a real risk then of data loss - as Dropbox does delete files to bring people under quota. You are also given multiple email reminders before subscriptions renew. 

How would the approval process work? I do actually think a toggle to cancel is a great idea but not sure it would work in that approval system.
