Why do my credits expire?
How credit expiry works, when unused credits are removed, and how to make sure you use them in time.
Every time your subscription renews, a new batch of credits is added to your account. Each batch stays valid for three billing periods. After that, whatever is left in that batch is removed.
Because new credits arrive every period, you almost always have multiple active batches at the same time. Your total balance is the sum of all active batches.
