Zocdoc, Inc.

"As you know, Zocdoc allows you to book appointments with doctors who list their medical or dental practices on our service.  Each practice registered with Zocdoc receives usernames which allow staff members to access Zocdoc's system (the "Provider Dashboard") to view appointments and other information you provide when you book an appointment. In June 2015, we learned of programming errors in the processes responsible for managing username access the Provider Dashboard, and therefore potentially view your personal information, after their usernames were removed, deleted or otherwise limited."The information compromised included names, email addresses, phone numbers, Social Security numbers, appointment history, insurance member ID and other medical history.
