[{'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: When you share your OneDrive content with your friends via a link, an email with the link is sent to those friends. The link contains an authorization code that allows anyone with the link to access your content. If one of your friends sends the link to other people, they will also be able to access your content, even if you did not choose to share the content with them. To revoke permissions for your content on OneDrive, sign into your account and then select the specific content to manage the permission levels. Revoking permissions for a link effectively deactivates the link. No one will be able to use the link to access the content unless you decide to share the link again."}, {'role': 'assistant', 'content': 'This clause is fair. The privacy practices mentioned are: nan.'}]
