Can Tumblr Track Individual Viewers?by Kevin Lee
Tumblr Knows Your Browser Information
Any website can use code to determine the browser you're using. Tumblr records your browser type, version, operating system and the type of device you're using to access Tumblr pages. This means that it knows if you're using a mobile device or a computer to view a page. Tumblr may also detect certain types of extensions your browser uses.
Tumblr Knows Where You Came From
When you click a link on one Web page to visitor a new site, the new site can determine the URL of the site that referred you. Tumblr records this referrer information along with the date and time of all Web requests you make while you're on the site. Although some people may see this type of tracking as a privacy invasion, it's common practice and all Web browsers make it possible for sites to do this legally.
Other Items Tumblr Tracks
Tumblr also has the ability to determine your IP address. This is a unique number that identifies your computer on the Internet. That number alone, however, cannot identify you by name. IP addresses help Tumblr combat malware, spam and identify theft. In some instances, Tumblr records your geographical location by using your IP Address to check a database that stores geolocation information.
Tumblr Can Identify You
These tracking techniques apply to Tumblr members and people who simply visit a Tumblr page. Although most tracking methods cannot identify you as an individual, Tumblr can determine who you are if you have an account. This is possible because, when you sign up for a new account, you provide basic information, such as username, email address and possibly a birth date. Tumblr notes that this information may personally identify you.
