All of us use Chrome Sync, and most sync everything including our passwords. Do you want to know how many Bookmarks , preferences, themes, extensions, apps, and autofill entries you have saved on Google Servers ? Do you know how to remove them ?
I can tell you how !
ps: Please be sure to use this ONLY if absolutely necessary.
You can stop syncing your data on Google Chrome servers and erase all data from Google Dashboard. Your dashboard will tell you how many Bookmarks and preferences etc you have saved on Google’s servers. They won’t show the number of passwords because they stay encrypted there.
How To Stop Sync and Erase Data
Go to your settings page either by clicking he wrench icon or typing in chrome://settings in your addressbar. Under “personal stuff”, look for “Stop Syncing This Account” Â “Remove synced data on Google Dashboard“
Now, this will stop syncing your data between the server and the current computer. If you want to remove data from the server, click on the link “Remove Synced Data On Google Dashboard'” and it will take you to your dashboard and will ask confirmation to delete data. This page also gives a stats on how many preferences, bookmarks etc you have saved on the server.
Again, do this ONLY if you wish to delete the whole data, which can not be recovered once deleted.
