How do I change my plan?
Go to Settings → Billing, find the Current plan section, click Change plan, and pick a new tier. Confirm once. The new budget lands in your wallet immediately, prorated for the current cycle.
What happens when I upgrade?
The difference in budget is added to your wallet for the remainder of the cycle. If you upgrade from Tester to Serious halfway through the month, the remaining half-cycle's difference is added to your balance.
What happens when I downgrade?
Your budget adjusts for the next cycle. The current cycle isn't reduced — you keep what was already issued. Unused credits from your previous plan stay in your wallet and roll over while you're subscribed.
