Subscriptions are prepaid plans which renew on an annual basis. Subscribers can cancel their plan at any time before renewal and it will remain active until the end of the subscription period. Subscriptions are currently available in the following tiers: mobile, professional, and business. For more information, visit Products and Pricing.
Licenses, on the other hand, are for ongoing use of a specific application. Licenses are application, major version, and platform-specific. For example, a license for Cinemagraph Pro for macOS only unlocks the 2.x version of the macOS app and does not unlock Cinemagraph Pro for iOS. Persecond for macOS licenses are currently available for purchase on the App Store and online Flixel Store.
