If you are running out of credits, you can purchase a top-up. These credits will be added to your balance and they never expire. Please remember, that top-up does not unlock Premium features. If you are on a Free plan and you purchase a top-up, you stay on a Free plan, with limited access to Kukarella’s features. If you do upgrade your plan to Premium, you’ll then get a 30% discount for all top-ups.
