Processing of personal information in the US and other territories

Your personal information may be transferred to, and processed in, countries other than the country in which you are resident. These countries may have data protection laws that are different to the laws of your country. Specifically, our servers are located in the United States, and our third party service providers and partners operate around the world. This means that when we collect your personal information we may process it in different countries. However, we have taken appropriate safeguards to require that your personal information will remain protected in accordance with this Notice.

EU-US and Swiss-US Privacy Shield Frameworks

With respect to personal information we receive in the United States concerning individuals in the EU and Switzerland, we comply with the EU-US and Swiss-US Privacy Shield Frameworks as set forth by the US Department of Commerce when we transfer personal information from the European Union, the United Kingdom, and Switzerland to our servers in the United States for processing. Please see our Privacy Shield Notice to learn more. If there is any conflict between the terms in this Notice and the Privacy Shield Principles (as set out in the Privacy Shield Frameworks), the Privacy Shield Principles shall govern.

Security safeguards

We use appropriate technical and organizational security measures to protect personal information we process about visitors to our Website against unauthorized access, disclosure, alteration, and destruction. However, please note that no Internet transmission can ever be guaranteed 100% secure, and so we encourage you to take care when disclosing personal information online and to use readily available tools, such as Internet firewalls, secure email, and similar technologies to protect yourself online. For the latest information about the controls we have in place to safeguard personal information, view our Security Overview.

Data retention

We retain your personal information where we have an ongoing legitimate business need to do so (for example, to provide you with a service you have requested or to comply with applicable legal, tax, or accounting requirements) and for a period of time consistent with the original purpose as described in this Notice. We determine the appropriate retention period for personal information on the basis of the amount, nature, and sensitivity of your personal information processed, the potential risk of harm from unauthorized use or disclosure of your personal information and whether we can achieve the purposes of the processing through other means, as well as on the basis of applicable legal requirements (such as applicable statutes of limitation).

After expiration of the applicable retention periods, we will either delete or anonymize your personal information or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.


Depending on your location and subject to applicable law, you may have the following rights with regard to personal information we control about you:

Access, review, change, update, or delete your information
