Free Credits: Your 1,000 monthly free credits are added to your account automatically on the first of each month.
Subscription Credits: These are added on top of your free credits and renew every month. Any unused subscription credits expire at the end of each billing period.
Purchased Credit Blocks: Credits you buy outright remain in your account for up to one year from your last purchase. Here’s the clever bit: buying any new block of credits resets the timer and protects all your existing credits. Stay active, and your credits never expire.
Example: You buy 10,000 credits in January. In June, you buy another 10,000. Now all remaining credits from January (plus the 10,000 you just bought) are safe for another year from June.
