Yes! This is one of the core value propositions to our customers - all data that is acquired on your behalf from another data source, company, program, etc. will remain in your personal, sovereign datastore forever. Even if a company goes out of business, you stop using their service, or they decide to no longer store a certain kind of data, as long as the data from that service was, at some point, pushed into your Fulcra account, you will always have it.
