If Co:Create ever shuts down, what happens to my digital assets?

In the event that Co:Create were to shut down, you would be able to take your token contracts with you and use them without modification. All tokens deployed via Co:Create are owned by you via the owner address generated by Co:Create for you upon sign-up. In this hypothetical circumstance, Co:Create would also facilitate the transfer of ownership of token contracts to a fresh owner address of your choosing.
