License for WebViewer in a Chrome Extension

Technical Support WebViewer
1

To edit PDF locally on Chrome, embedded PDFTron PDF editor library to a Chrome extension. Clicking the extension icon just opens a new tab, where is a PDFTron editor page, user select a local PDF file, and save locally after edit.
The extension is intended to distribute as free usage, it’s non-commercial use, and have no PDF sharing features that might be used for Ads and promotion.

The library used in this extension is @pdftron/webviewer NPM module. I’ve found that it’s not a completely free package, and not sure about whether I can use it in my public extension.
So I’d like to know:

  1. Can I use the @pdftron/webviewer NPM module for free for creating a free Chrome extension to be published?
  2. If not, how much it will cost to purchase a license for it?
  3. What kind of license should I apply to my Chrome extension? Should I mention about your @pdftron/webviewer NPM module license and license my extension as MIT or Apache license?
    Or should I use a special license you enforce to me?

Please answer to my 3 questions. If it’s not too much expensive, I’m going to purchase it, because PDFTron PDF editor is so nice tool.

Kind regards,
Hotte

Hi Matt,
Thanks for the reply.
I’ve checked the licensing page at the first time. But there was no pricing information. Also, when I tried to contact your support team, it asked company information.
But I’m a person, and my extension is developed by me alone, and gonna distribute for free, as many freeware. In my case, where can I contact your sales team?
That’s why I posted the question here.

Please explain how can I contact or get pricing info in my case.

Many thanks,
Hotte
