What I'd really appreciate is a demo/sandbox version where I can try out the functionality without having to enter anything personal.

I appreciate that you have a (generous looking) free tier and various screenshots - but it just seems like something I'd want to play around with before taking the time to create an account and start entering personal data into.

We do offer a sandbox with preset examples that lets you explore the app. No need to enter any personal data, but you will need to sign up.

Thanks - I'll check it out then!
