Amendment of Ems Subscriber Agreement Related to Your Use of the Eze EMS General Data Protection Regulation Data Processing Addendum

The European Union enacted the General Data Protection Regulation (the “GDPR”) which will become effective on May 25, 2018. The services provided by Eze Castle Software LLC (“Eze”) may involve the processing of personal data subject to the GDPR. Effective as of May 25, 2018, the EMS Subscriber Agreement (and its equivalent forms) that you or your firm (“You” or “Customer”) have signed or are covered under will be amended to incorporate the General Data Protection Regulation Data Processing Addendum (the “Addendum”).  Highlights of the Addendum are provided below.  


  • In order to comply with the GDPR, Eze is updating the EMS Subscriber Agreement to reflect these regulatory changes.

The Addendum also states that Eze will process such Personal Data as a data processor and not as a data controller.
  • The Addendum makes the minimum changes to comply with the GDPR and is not intended to improve a party’s position under the EMS Subscriber Agreement.
