Yes. When a GoAnimate subscription lapses, the videos and assets (characters, backgrounds, props, and effects) are still saved on our servers. All features associated with paid subscriptions will stop working until the subscription is activated again, but your videos will be preserved.
For example, if you are a GoPremium subscriber and have replaced the GoAnimate watermark with your own, the GoAnimate watermark will reappear on your videos when the subscription ends. Once you re-activate your subscription, all features of the plan purchased will again be available.
