Everything happens in Settings › “Subscription & credits”. To get there, click your credit counter at the bottom of the left-hand menu.
Upgrade to a higher plan
Click “Manage subscription” and pick your plan. The summary shows what you pay today: whatever was left on your current plan is deducted. Your new credits land right away.
Downgrade to a lower plan
Pick the plan in “Manage subscription”: the change is made in the billing portal. It takes effect at the end of your current period.
Switch from monthly to annual, or the other way round
- Monthly to annual: pick the annual plan in “Manage subscription”.
- Annual to monthly: that isn't possible partway through your annual term. Write to us and we'll take care of it at your renewal date.
Cancel
Click “Cancel my subscription”. Your subscription stays active until the end of the period you've already paid for, and the date is shown (“Ends on …”). You keep your credits until then. After that, your account goes back to the free plan.
