> * If you are signed in to a Google site or signed in to Chrome and Google is your default search engine, searches you perform using the address bar in Chrome are stored in your Google account. Note the "or". If you're signed into Google and you do a Google search, that's stored in your account by default. The only reason signing into Chrome is relevant is that that also signs you into Google. > * Payments. If you are signed in to the Chrome browser and you have credit cards stored in your Google Payments Account, then Chrome will offer you the option of filling those cards into web forms. In addition, if you enter a new credit card into a web form, Chrome will offer to save your credit card and related billing information to your Google Payments account. This doesn't suggest any data being sent to Google unless you accept the offer to save a card to your Google Payments account. > * Language. In order to customize your browsing experience based on languages that you prefer to read, Chrome will keep a count of the most popular languages of the sites you visited. This language preference will be sent to Google to customize your experience in Chrome. If you are signed in to Chrome, this language profile will be associated with your Google Account and, if you include Chrome history in your Google Web & App Activity, may be used to personalize your experience in other Google products. View Activity Controls. Okay, this is one actual example of signing in causing more data to be sent to Google than would happen otherwise. It seems pretty benign, though.
