Upgrading to a higher plan is seamless and fair. You never pay twice for the same period: instead, the system recalculates your subscription so that what you’ve already paid is fully credited. Here’s how it works:

When you decide to upgrade, the cost of your new plan is prorated for the remaining days of your current billing cycle. The amount you’ve already paid for your existing plan is deducted, and you only pay the difference. This way, you can move freely to a more advanced plan whenever you need it, knowing you’ll always pay exactly what’s fair – no more.

(For downgrades, simply let your current subscription expire and purchase the new one once it ends.)
