For monthly subscriptions, unused credits roll over and accumulate up to 2x your plan's monthly limit. For example, if your plan allows 2000 credits and you have 500 left, you'll start the next month with 2500 credits.
If you've downgraded or canceled, your credits remain until the end of your billing cycle, then get capped at 2x the new plan's limit.
For annual plans, you receive all credits upfront to use whenever you want throughout the year.
