If it were me... I'd probably have the data stored in a postgres db, maybe use graphql+elasticsearch indexes to provide the linking and searching... then the user could simply supply aws creds and what not to their own instances and basically host their own data that way. UI/UX still would be proprietary but that data fully owned by user.
