I created an account just to ask this, so please don't leave me hanging.
Can anyone tell me which Chrome settings are actually saved on my PC? Because I know that some of the settings are saved on my Google account instead, but I don't know which is which.
Account-related settings are saved online, and (all of them?) are reseted when moving to (or reinstalling) a new OS. Restored after logging-in.
I'm not sure about the cache & browsing history, if they're saved locally. For more information, check the App Notes chapter, at the Chrome's homepage.
Illusions are an infinite paradise.
