Do my credits expire?

Credits expire 1 year after your last credit replenishment date. If you purchase a new Credit bundle, all of your current credits renew with the new purchase date. For example, if you purchase 500 credits in January and don't use all of them, they will expire on the same purchase date a year later. However, if you purchase more Credits in October, the remaining credits you had from January will now expire a year from October instead of January.
