If you’ve purchased a single license, it covers all projects/episodes/videos that utilize the specific track you purchased it for. There is no expiration date, and the projects will remain licensed forever.
If you have purchased a subscription, you can use the downloaded tracks in as many projects as you want but you have to make sure that the date you publish the content lies within your active subscription period.
After your subscription has expired, you are not allowed to publish any further content with the downloaded music.
If you have any doubts, please contact us through our chat or email us at support@hooksounds.com, and we will gladly help you out!
