You can get all updates for the current major version (1.x.x, 2.x.x etc) for one year after you purchased. If we release a new major version before the year is up, you will receive updates for that major version as well.

After that, you will need to purchase the software again to receive further updates. You'll get a 50% discount when you purchase a new version.

Frankly, because we don't want to spend the time to implement a subscription checker in the software.

Also, maybe you're happy with what is in the Software version 1.4, and don't require more features, so why should we force you to pay? If you like what we add in Version 4, you might want to purchase it again, and you'll benefit from a 50% discount because you already purchased the software.

The software is open source, but open source doesn't mean free as in "free beer". Instead, it means "Free as in Beer" - which means: Beer usually costs Money, but after you purchase it, you can do with it whatever you want.

“Free software” means software that respects users' freedom and community. Roughly, it means that the users have the freedom to run, copy, distribute, study, change and improve the software. Thus, “free software” is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech,” not as in “free beer.” We sometimes call it “libre software,” borrowing the French or Spanish word for “free” as in freedom, to show we do not mean the software is gratis.

We've spent time and will continue to spend time to develop this software, and we want you to have the right to do whatever you want with the software - as soon as you purchased it.
