How To Buy

Buying SimpleDiagrams is easy. Just click on the "Buy Now" button above for the type of license you want. That will pop up a payment form provided by FastSpring, the efficient and secure payment processor.

After you finish purchasing your license, you'll receive an email with your license key and a link to download the application (you only need to download the app if you haven't installed the trial already). You're now ready to register SimpleDiagrams with your email and license key!

So simple you don't even need a diagram.


Three Installations

Let's be honest. One installation just doesn't do it for you. You need to install an application on multiple computers: your laptop, your home computer, etc. So, when you purchase a SimpleDiagrams license for yourself, you can register the application up to three times (and unregister it when you want to get a registration back). That's as long as it's for your use only. Installing a version for your cousin Daryl doesn't count. Then again, I have no idea how we'd find out about Daryl.

When you purchase a volume license, you purchase one license for each user. Each user can install SimpleDiagrams on three machines. Please read the SimpleDiagrams End User License Agreement for details.
