Show HN: InstaPDF - Go Paperless (iOS,Mac) (instapdf.com)

I've been working on InstaPDF for the last 7 years. I'd be happy to answer any questions you might have.

This doesn’t seem to use device native cloud storage (ie iCloud on macOS/iOS).

Why?

This is more of a general thing, but you’re doing it too - why do app developers feel this need to store data in their own secret squirrel cloud system that the user has zero reason to trust.
