How subscribe-to-own works
Flow® Suites use what we call a subscribe-to-own model. It's better than an ordinary subscription plan and different from a rent-to-own plan.

Why is it better than a subscription?
Usually, when you cancel an ordinary subscription service, you instantly lose access to the products included in the subscription. Flow subscribe-to-own is different. For every month you are subscribed, you earn credits. You are free to cancel at any time and retain your credits, as well as the products you’ve purchased with them.
Flow® Credits can be used to buy perpetual licenses of the plug-ins included in Flow. You also get exclusive access to Flow® Credit Store Plus, where you’ll find even more Softube plug-ins to purchase with credits.
If you have purchased all the plug-ins that make up a Flow, you now own those products perpetually. So if you decide to cancel your Flow® subscription, you can still use that particular Flow within the Flow plug-in, since you now own those plug-ins perpetually.
With an active subscription, you'll pay 14.99 USD/EUR per month and earn 30 credits, or 24.99 USD/EUR per month and earn 60 credits. That means for every USD/EUR you spend on your Flow® subscription, you earn 2 credits. Therefore, you are effectively receiving a 50% discount on the list price of the plug-ins found in the Flow® Credit Store.
If you have purchased all the plug-ins that make up a Flow, you essentially own that Flow. Even if you cancel your Flow® subscription, you can still use that Flow within the Flow plug-in.
