Facebook's new policy explains what types of information it collects and how it uses the data. These changes help users digest just how Facebook knows all about you. So here are the five things to remember about its data polices. First is location. Businesses can access your location information based on your smartphone's GPS information along with Bluetooth and Wi-Fi signals. Secondly, let's think beyond Facebook. Not only does it track what you do on the site, but it collects information about your activities on outside websites and mobile apps like Instagram and WhatsApp. Next up is ad targeting. If you don't decline or opt out, companies whose websites you visit off Facebook can use browser cookies to track you, resulting in more ads on Facebook. Remember all eyes are on you. Facebook explained, 'We collect the content and other information you provide when you use our Services, including when you sign up for an account, create or share, and message or communicate with others.' Lastly, Facebook is testing a shopping spree tool to let people buy things directly through its site. Facebook will collect information about your transaction, including your credit card number and billing and shipping address.
