Credits work like a deposit

You put money in, you spend it. That is all.

  • Credits never expire, and there is no monthly reset or rollover cap.
  • Subscription credits stack on top of the balance you already have.
  • A failed generation is refunded automatically, without a ticket.
  • Credit packs need no subscription. Buy once, spend whenever.
  • Cancel from your profile without emailing anyone. It runs to the end of the period you paid for, and you see the date.
  • A person answers support@azurade.com.

The long version of why we will not sell expiring credits is on the blog.
