As long as you have an active YFS PRO subscribtion, you can use all our sounds in your projects - subject to our terms of use and license agreement. If you decide to cancel your subscription, you will lose unlimited access to the sounds after your subscribtion has been expired. In addition you will also lose all the other benefits that come with your subscribtion - e.g. you won't be able to access the cloud storage any longer and HQ WAV downloads from the website won't work anymore. All sounds that were available at the time of subscription can still be used in previous projects, but not in future projects. For future use of the sounds there are two options: 1. extend the subcribtion 2. purchase the sounds individually 3. Use the free mp3s (if available) and credit yourfreesounds.
