Also identify any privacy practices mentioned: We retain the personal information you provide while your account is in existence or as needed to provide you services. We may retain your personal information even after you have closed your account if retention is reasonably necessary to comply with our legal obligations, meet regulatory requirements, resolve disputes between Members, prevent fraud and abuse, or enforce this Privacy Policy and our User Agreement. We may retain personal information, for a limited period of time, if requested by law enforcement. Our Customer Service may retain information for as long as is necessary to provide support-related reporting and trend analysis only, but we generally delete or de-personalize closed account data consistent with Section 3.1., except in the case of our plugin impression data (i.e., the information that you visited on sites carrying our social plugin, but which you did not click on), which we de-personalize within 7 days (although we do maintain 30 days worth of webserver logs for security, debugging, and site stability purposes only) by creating aggregate data sets that cannot be traced back to individuals."}, {'role': 'assistant', 'content': 'This clause is fair.
