Frequently Asked Questions
How does the payment process work?

We sell licenses for our data modeling tools through FastSpring, a secure third-party payment provider that acts as the Merchant of Record. This means FastSpring handles the entire transaction, including payment processing, taxes, and invoicing.

Why FastSpring?

  • Secure and reliable checkout experience
  • Supports multiple payment methods worldwide
  • Allows us to focus on improving our software

For you, it's similar to buying a book from a bookstore - you're purchasing our software through a trusted reseller.

Billing and Invoicing Support

If you have any questions about payments, billing, or invoices, please contact FastSpring's support team directly.

When will I receive the license key?

Your license key is sent automatically by email once your payment has been successfully processed. In most cases, this takes only a few seconds (up to a few minutes). For alternative payment methods (such as bank transfers), your license key will be delivered after the payment is received and confirmed. If you don't receive your license key, please check your spam/junk folder or contact support.

What does my license cover?

Your license is personal—one user, unlimited devices. Install on Windows, macOS, or Linux, and use it on your laptop, desktop, or wherever you need it. Your license is tied to you, not your hardware.

Your license never expires. Even if you never renew, you keep using it forever.

Getting updates is optional:

  • Year 1: Free updates included with your purchase
  • Year 2+: Renew for new features and security updates
  • Prefer your current version? No problem—keep using it without renewing

For full details, please see our licensing model page

What happens if I don't renew?

Your license never expires. You keep using the version you have. Renewal is only if you want new features and updates.

Can I renew after a break?

Yes. Renewal is always optional and available anytime.

Are discounts available?

Yes, we offer several discount programs for new licenses.
Please visit our discount programs page to learn more.

What is your return and refund policy?

Try our data modeling tools risk-free. We offer a fully functional trial so you can test our tools before you buy. If you make an accidental duplicate purchase or buy the wrong product, our support team will gladly sort it out for you.

I have lost my license key. Can you help me?
