It's difficult to know for sure where to store data in a GDPR world. People move. People have multiple citizenships. People open accounts in countries where they aren't citizens. People give up citizenships. People share documents with other people. People ingest data from one product to another. People comment on documents. It's really, really hard to get all of this down. It's not even clear legally what to do in various scenarios and it's impossible to enumerate them all. It's difficult.
