I guess I do not understand your question. I don't think that I synchronized it to anything. I answered the privacy part and read everything and pressed that I understood the privacy part. I then joined the King site and when I went back to play it was on level 1.
If you click on the link that I attached to my respond before this, you can find how important to synchronize your game to either King account or Facebook to save your progress Incase something happened.
