Coffalyser.Net™ and Coffalyser digitalMLPA™ are free and will remain free in the future. You are still required to generate a free license for two main reasons: to allow us to contact you, and to ensure that you use an up-to-date version of the software.
We also use the licensing system to ensure that older versions of the software are no longer used. All licenses periodically expire, at which point they must be renewed via a simple procedure. If we release an updated version of the software, we will (eventually) stop renewing the licenses of older versions. This ensures that you always use an up-to-date version, and that everyone benefits from the latest improvements.
