[{'role': 'user', 'content': 'Analyze the following clause from a privacy policy and determine if it\'s fair or unfair. Also identify any privacy practices mentioned: Information Collected Using Cookies and Web Tags: Cookies are text files that may be sent to and saved by your web browser when you access a website; your web browser stores these cookies in a way associated with each website you visit, and you can generally see your cookies through your browser settings, depending on what browser you\'re using. A web tag is code or a pixel embedded in a web page, or email, that allows Tumblr or a third party to see that you have looked at that page. We use cookies and web tags to enable our servers to recognize your web browser and tell us how and when you use the Services, as described above in "Information Related to Use of the Services." Our cookies do not, by themselves, contain information that personally identifies you, and we don\'t combine the general information collected through cookies with other such information to tell us who you are. However, we do use cookies to identify that you have logged in, and that your web browser has accessed the Services, and we may associate that information with your Account if you have one. We may also store unique or near-unique identifiers that we associate with your Account in our cookies. This information, in turn, is sometimes used as described above in "Information Related to Use of the Services." Most web browsers have an option for turning off the cookie feature, which will prevent your browser from accepting new cookies, as well as (depending on the sophistication of your web browser) allowing you to decide on acceptance of each new cookie in a variety of ways. If you disable cookies, you won\'t be able to log into your Account, and so won\'t be able to use the vast majority of our Services; as such, we don\'t recommend disabling your cookies when using the Services. Some services that we use (including Third Party Services), such as Google Analytics and Yahoo Web Analytics, use web tags and may also place their own cookies on your browser, and individual blogs on our network may contain code that places their own cookies. We also run limited-time studies using web tags, sometimes with third parties, to, for example, measure the effectiveness of our advertising or email. Note that, unless otherwise disclosed, this Privacy Policy covers our use of cookies only and does not cover the use of cookies by third parties.'}, {'role': 'assistant', 'content': 'This clause is unfair.
