You're free to cancel your subscription at any time. Upgrade whenever you need a higher plan. You can also downgrade your plan if you wish to lose access to features of a higher plan after a 12 months period.
Since we don't charge you for the cost of development but only for support and maintenance we expect you to stay with us for a 12 months period until our investment returns. If, for whatever reason you wish to terminate your subscription before that period ends, that's ok, too. We'll take your site offline and cancel your subscription. No hard feelings.
