This is a cool idea but if you accidentally hit the back button or refresh it loses all your progress with no obvious way to skip ahead. Frustrating.

It can be solved with saving stuff to local storage, but I tried to not use it to be more GDPR compliant...

Isn't local storage pretty good for compliance? It doesn't automatically send the data to your server like a cookie would, so as long as you don't send it, you haven't collected it.

I have a hard time imagining a GDPR complaint in which storing ones own data on their computer would constitute a privacy violation

As long as you do not transmit the data ever, using localStorage isn't a GDPR concern other than that you should mention it (and the in-browser-only use, with data never leaving the users' systems) on your privacy policy page for the sake of transparency and to avoid users asking about it.
