So even though it would usually sync from Ankiweb because no conflicts would arise, you can overwrite Ankiweb by uploading the local, and then going to your phone or other device and re-syncing.

If you check this box, close the preferences window, and then sync, anki will come up with the window asking you if you want to download the remote or upload the local. There you'll see a check box that says "On next sync, force changes in one direction". You can go to your desktop, and then under "Tools", choose "Preferences" and then go over a tab to the "Network" tab. But you think "oh no, I don't want to actually save that as a review". Let's say for example, that your friend wanted to see how Anki works, so you show him on your phone. Lastly, you can also optionally "force" changes in one direction from your desktop. This also means you can study on your phone, sync, and create a new deck on your desktop and then sync from your desktop and there should be no problem, you just have to remember to sync your phone one last time, after you sync your desktop. So, if you study on your phone and sync it, and then study a different deck on your desktop, and then sync, Anki will not ask you to overwrite anything, because there aren't any conflicts (but after syncing your phone and then your desktop, you would have to sync your phone again to get the changes from your desktop). But, as far as I'm aware, this only happens when there are actual conflicts in studying.

If you study on your desktop, don't sync, then study on your phone or another device and sync, and then go back to your desktop to sync, Anki will ask you to force the changes in one direction, either by overwriting the "local" (what's on your desktop) with what is online, or uploading from your desktop to overwrite your "remote" (what's online) If you're just studying using one device (like your desktop), there should be no problems - as realmayo said, it's just like backing up your decks/stats The two above posts are correct as far as I'm aware, but just to clarify,
