We follow best practices and generally accepted standards to store and protect the Personal Data we collect, both during transmission and once received and stored, including utilization of encryption where appropriate.

We will hold your Personal Data in our systems for as long as is necessary to provide the Services you have requested, and thereafter for a variety of legitimate legal or business purposes. These might include retention periods:

  • mandated by law, contract or similar obligations application to our business operations;
  • for preserving, resolving (customer support), defending or enforcing our legal/contractual rights; or
  • needed to maintain adequate and accurate business and financial records (billing purposes).

We take steps to destroy or permanently de-identify Personal Data once it is no longer needed. In some cases, we choose to retain usage information in a depersonalized or aggregated form. Once aggregated, this information ceases to be Personal Data and will not be subject to our regular retention policies or subject to the exercise of your rights and choices as outlined above.

Personal Data provided to TeleSign may be transferred to, accessed from and otherwise processed in the United States, the European Union, and any other country in which TeleSign or its affiliates operate facilities. Some of these facilities are located in a country outside of the US/EU, e.g. Serbia. These countries may not have similar data protection laws as the GDPR.
