The data and all of your edits are automatically saved inside the project file. When you’re finished modifying the data, you can export it back out into the file format of your choice.

You may wish to create a new account just for OpenRefine, or add OpenRefine to an existing account. Each host will have a slightly different method, but generally speaking: look for “accounts with access” to the database you wish to authorize, and within the settings for that account, look for “allowable hosts” or “access hosts.”
