What are the additional limitations on the demo prior to purchasing a subscription?

[Beeve1965]

I had a few questions regarding download/licensing of ProMultiTouch: First, I was able to download and install the software. I can save files and it appears, I can begin creating a project. What are the additional limitations on the demo prior to purchasing a subscription? Am I just unable to export/upload my project to your servers to access it on a device?

Second, I was wondering if I did purchase a subscription and then later decided to just purchase a full license, are there any issues that would arise? Just hoping to get some overall clarification on demo version vs. subscription vs. full license.

The only difference with the paid version is the ProMultitouch logo overlay in the exported project. To export and run your projects you can register here for free: https://id.promultitouch.com/register.
A perpetual (full) license:

• Will allow you to use the software indefinitely.
• Entitles you to download all updates to the software (applicable in the first year).
  Yes, you can subscribe, unsubscribe and buy a full license.
