Chrome comes with features that enable to send certain data to Google’s servers. We recommend you don’t disable these features because they are good for some stuff. You can, however, decide for your browser what to send to Google.
The straight-forward thing first: you can open a private browsing window by clicking on Chrome’s Menu and selecting “New incognito Window” to start private browsing.
Decide for Chrome What to Synchronize
If you’re logged in, Chrome will automatically synchronize your browser data to your Google account. This is to enable you access your information such as bookmarks and open tabs on your other devices.
You can view and change the sync options by clicking Menu > Settings.
If you want your Chrome to not sync any data, click “Disconnect your Google Account” under “Sign In”.
Click “Advanced sync settings” and select “Choose what to sync” to allow syncing of only selected types of data.
You can choose to encrypt your data to be synchronized with your own paraphrase for a little more privacy by selecting the “Encrypt all synced data with your own sync passphrase”. You’ll have to enter the sync passphrase into Chrome on your devices.
If you want to keep Google from using your Chrome browsing history while still staying signed into Chrome with Google account, click the “Google Activity Controls” link at the bottom of the Advanced Sync Settings pane and unchecking the “Include Chrome browsing the “Include Chrome browsing history and activity from websites that use Google services” checkbox on the web page.
Pick Online Services for Chrome
Click the “Show advanced setting” link at the bottom to find more privacy options and disable or enable things to your liking.
Here’s a brief explanation of the checkboxes:
Use a web service to help resolve navigation errors:
Disabling of the option prevents Chrome from sending your mistyped addresses to Google for it to fetch suggestions of similar addresses you might have meant.
Use a prediction service to help complete searches and URLs typed in the address bar:
With this option disabled, Chrome won’t send your input in the address bar to your search engine until you hit “Enter”.
Use a prediction service to load pages more quickly:
To make surfing fast, Chrome preloads pages on a website it thinks you might open next, which place cookies in your browser like a visited page. Disable this option to make Chrome load pages only on a click event.
Automatically report details of possible security incidents to Google:
Enable or disable this option to allow or disallow Chrome to detect and suspicious website data to Google.
Protect you and your device from dangerous sites:
Chrome uses Google’s Safe Browsing service to test web addresses against known dangerous addresses.
If you try to open a web address that matches something on Chrome’s already downloaded list of dangerous websites, it’ll send the address to Google. Disable this option if you don’t want Chrome to protect you from malware or phishing websites.
Use a web service to help resolve spelling errors:
Enable this option to send your input in text boxes in your Chrome to Google servers for a thorough spellcheck, or disable it if you want to use Chrome’s local spellcheck on your computer instead.
Automatically send usage statistics and crash reports to Google:
Enable this option if you like to send important data about features usage and crashes to Google to help it fix bugs and improve Chrome.
Send “Do Not Track” request with your browsing traffic:
Check this option to make Chrome send “Do Not Track” request to websites. It’s especially relevant to note that websites may or may not honor the request – they mostly don’t.
Decide What Websites Can Do
Click the “Content Settings” under privacy to better control what websites can (or cannot) do in your Chrome.
Chrome lets websites place cookies on your computer to save your login state and other things. You can select “Keep local data only until you quit your browser” to get Chrome to clear cookies automatically on exit, or select “Block sites from setting any data” to block sites from placing cookies altogether.
With the “Block third-party cookies and site data” option enabled, third-party cookies won’t make it to your Chrome.
Use the “Mange Exception” option to set exception if you like to treat cookies from certain websites differently.
The other options tell websites how to use features like your location, webcam, microphone, and browser notification. By default, they have to get permission for each of these.
If you don’t want Google to offer pages translation (which it does by default), uncheck “Offer to translate pages that aren’t in a language you read” under Languages
Lastly, Chrome doesn’t allow disabling of automatic updates – which is a good thing. This is to ensure that you never miss on security updates.
