What does my license cover?

You can use your license to unlock Omni on a single Windows computer for a period of 1 year.

How do you process my purchase?

We accept Paypal or SWIFT payment.

For PayPal, after you email us for requesting a license, we will send you a PayPal payment request. After we receive the payment confirmation we will send you your license key.

Why don't you offer refunds?

There's no way to easily "turn off" a serial number once it's been issued. If I offered refunds, people could just buy a license, unlock the app and then request a refund. They'd get their money back and still have an unlocked copy of the app. We offer a lengthy free-trial period so it's easy to decide if you want the app before you buy a license. For these reasons, all sales are final.

What information does Omni exchange in its internet traffic?

No sensitive information, that is granted. These are all the situations Omni will do internet traffic:

  • Loading home page news
  • Loading Playground pages
  • Activating your software when you submit your license information
  • Checking if an updated Omni version is available
  • When the .html page you load in Omni requests some internet resource (images, AJAX, etc.)


I realize that Omni only runs on Windows 7+. I agree not to hold Ramon F. Mendes or MI Software liable for any damages caused by the app. I also understand that refunds aren't possible.
