  • We maintain multiple copies of your data, across datacenters, for redundancy, and we share with you where your data is located and will provide one-month advance notice if we expand the region where your data is stored into a new country.
  • We tell you who has access to your data and under what circumstances.
  • You have 24/7 phone support for critical issues.
