Do credits expire?
Monthly budget credits don't expire while you're subscribed — they roll over month to month with no "use it or lose it." Manual top-up credits never expire, even if you take a break for months.
How are credits spent?
When a task runs, the system spends credits that would otherwise expire first, then draws from the rest. This protects your balance automatically.
What happens if I cancel my subscription?
Any remaining budget credits stay usable through the end of the paid cycle. After that, only top-up credits remain. You can see the breakdown in Settings > Billing.
