If you’re worried about this happening, your best bet is to clear out your Chrome sync data altogether and stop using the feature. Here’s how to do that.
1. Go to Google Dashboard (you may need to verify your password even if you are already signed in).
2. Click on the “Manager Chrome Sync” link, which is underneath the “Chrome Sync” section.
3. On the next page, click on the “Stop and Clear” button at the bottom of your data.
You’ll see a warning notification letting you know that you can’t get your data back once cleared, and it may take several hours for it to complete. Just click on “OK” and you’re done.
