Regarding to Google, "Google Chrome is a browser that combines a minimal design with sophisticated technology to make the web faster, safer, and easier". Unfortunately, each Google Chrome installation contains a unique ID that allowing identifying its user. Google doesn't make it an easy job to remove this ID.
The UnChrome application was designed to help you with this task. It replaces your unique ID with Null values so that your browser cannot be identified any longer. The functionality of Google Chrome is not influenced by this. You only need to apply UnChrome once.
If Google Chrome is started now then please close it. Afterwards, please click on the link below to anonymize your Chrome installation.
