Correct. We're leveraging localStorage to save answers across "pages" (using Vue). We could probably serialize / base64 encode the object we've saved and then let someone share it.
I think the way the question was worded raised my eyebrows a bit. It left me thinking that "sharing socially" would be turned into "let's include this social sharing widget that will track our users" (which always turns me off of a product) vs "let's make sure a shareable link works a single (or multiple) times for people who have the link".
