There could be a user-centric back end that you could tie in to an account, if it matters. You would export your history to the backend and then log in to the data from the new frontend. That prevents a denial of service caused by numerous large data collections attempting to forward their data all at once.
That then causes me to wonder if data could be hosted separate from the services. That would mean that there would have to be individuals willing to provide that storage and bandwidth.
I actually have a mini workshop for making little shit. I made matching desks for my son and me 7 years ago. Even though my son beat the crap out of his and mine lost a load support, they are still standing better than any IKEA desk I have seen.
