Recently, the team at Scirra updated their post, to clarify that Construct 3 works offline. Unfortunately, this is very vague:
To start off, is the offline version still browser based? Does it require an internet connection to access it in the first place?
The preferred option would be to have a fully offline stand-alone application. This would mean I would not have to rely on browsers whatsoever when using the program.
Will I be able to export the projects when offline? This would be a major inconvenience if I couldn't.
