It sounds like there are two things that bother you.

1. When you sign in, the local data is merged with the data from your sync'd profile/account. This is intended. If you want to keep them separate, use different chrome profiles. You can read more about the feature at https://support.google.com/chrome/answer/2364824?co=GENIE.Platform%3DDesktop&hl=en

2. You're saying when you sign out, all your local data is deleted. This is not the default behavior. Typically, when you're signing out, there should be a pop up. In that pop up, there'll be check box next to text that reads (on desktop) "Also clear you history, bookmarks, settings, and other Chrome data stored on this device." If you check this check box, it'll delete all the profile data for the profile that's being signed out. If you don't check it, it'll just clear the sync metadata, all the actual data will be persisted. You'll still have your bookmarks, etc.

Hope that helps clear things up for you!

Both of these cases appear to be working as intended, resolving. Unfortunately, understanding chrome profiles is quite confusing and never explained well. This is a known issue, and on our radar for something we want to invest in down the road.

There is no such checkbox to preserve the contents.

STR:

1. Click on Manage People menu option after clicking on profile name in
chrome header (near close/minimize buttons).


​
2. Now hover on profile card/box and there will be an option remove that
user.


​
3. Now click on click on Remove this person


​
4. The above-shown warning message clearly says that 1081 history/session
items will get removed and I can not access them without logging in with
the same account.

Thanks for the help.

Ah, I see, doing that will always remove the profile data. What you want to do is:

1. Open a window in the profile you want to sign out in
2. Click on the three dot menu button
3. Click on the "Settings" menu item
4. Click on the "Disconnect your Google Account..." button
5. Click "Sign Out" button (and don't click the checkbox)

This will keep the profile (and data) around, but stop syncing and remove the google account.

Worked, thanks.
