[{'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: (c) Activity Information: While using the Viber services, we will collect, and other users can see, your connection status, whether you have received and seen messages sent to you, if you are currently on another call, and information related to the calls you have made and received; if you don't want people to know that you're online or that you've seen messages, you can change these options in your settings. As for delivered status and call information (length of the call, missed calls etc.), we believe they are important for Viber users and therefore cannot be canceled. For Secret Chats, we will notify the other members of any screenshots you've been taking (so please respect the vibe and don't take them)."}, {'role': 'assistant', 'content': 'This clause is fair. The privacy practices mentioned are: nan.'}]
