Everyone has seen it in practice that some companies try to pull a bait and switch by then changing the terms of licenses or simply shutting down the servers when going out of business. Since this is a desktop tool not hosted on any server infrastructure, at least the latter part isn't that much of a risk. You still have to have some trust in me to honor the license terms, but I try my best to build that trust.

There is also an offline license functionality, meaning that if you obtain a lifetime license and request an offline license file, that one will not perform any verification with any online services, so it will work forever without any dependency on some SaaS infra. Anyone interested in that can simply request an offline license, you can find the details on the pricing page. The offline licenses are also often used for usage in air-gapped environments.
