Most importantly, the privacy policies and controls you have over your website data will not change. Just as it was before, your website’s data is governed by the data sharing settings, which you control directly. You can still choose how much, if any, of your website’s data to share with Google to help us improve our products, provide anonymous, aggregate statistics, or make enhanced features like Conversion Optimizer available to you. Your website data will not be used for purposes other than those that you specify in your settings, which you may change at any time. You can find more information about data sharing settings here.
