Is there a way to download a database that we've created on Ragic?

Yes, you can do a manual backup of your account, just go to the Backup & Restore page in your Account Setup under the Start tab to get a backup of your account. You will still need Ragic to read the full backup of your account. If you would like to install Ragic on your local computer, we have an on-premise version that you can consider.

For detailed information regarding Backup & Restore, please refer to here.
