Transfers of Personal Data Outside the EU, Switzerland, the UK and the PRC

Simpson Thacher is an international law firm with multiple offices and affiliated entities across a number of global jurisdictions. As such, personal data may be transferred to a country which may not provide the same protections to personal data as the country in which you reside. In particular, personal data from the EU, Switzerland, the UK or the PRC will be transferred to, and processed in or shared across computer networks or otherwise with our offices in the United States and, in certain instances, where necessary to provide our services or conduct operations in a given instance, it may be shared with individuals in our others offices as necessary.

To provide adequate protection for these transfers in accordance with applicable data protection law, Simpson Thacher has taken all necessary and appropriate measures to protect your personal data and ensure an adequate/equivalent level of protection, including but not limited to executing the appropriate contractual clauses based on and conforming to the European Commission approved standard contractual clauses and the UK Information Commissioner’s International Data Transfer Addendum. To obtain further information on the mechanisms that we have put in place to safeguard the transfer of your personal data to countries outside of the EU, Switzerland, the UK, or to inquire with respect to more details on the transfers of your personal data outside the PRC, please contact us at [email protected].

Your Rights

Depending on where you live, you have various rights with respect to our use, processing and sharing of your personal data. Please note that there are exceptions to some of these rights, so that requests may be denied if, for example, making the information available to you would reveal personal data about another person, or if we are legally prevented from disclosing such information.

  • Access: You may have the right to request a copy of the personal data that we hold about you. You may be entitled to see the personal data held about you. If you wish to do this, please contact us at [email protected].
  • Accuracy: We aim to keep your personal data accurate, current, and complete. We encourage you to contact us at [email protected] to let us know if any of your personal data is not accurate or changes.
  • Objecting/Deletion: You may also have the right to object to processing of your personal data and to ask us to block, delete or restrict your personal data subject to certain exceptions. If this right applies, once we receive your request and verify your identity, we will delete (and direct our service providers to delete) your personal information from our records, unless an exception applies under applicable law.
  • Portability: You may have the right to request that your personal data is provided to you, or to another data controller, in a commonly used, machine-readable format.
  • Withdrawal of Consent: You may have the right to withdraw your consent at any time, when consent is relied upon as the legal basis for our processing of your personal data. We note, however, that such withdrawal of consent will not impact the lawfulness of any processing before such withdrawal (please see “Marketing Communications and Withdrawing Consent,” above).
  • Confirmation: You may have the right to request confirmation from us as to whether or not we are processing your personal data and to access your personal data in our possession.
  • Disclosure: You may have the right to request information about public and private entities with whom we share your personal data, where applicable.
  • Complaints: If you believe that your data protection rights may have been breached, you may have the right to lodge a complaint with the applicable supervisory or regulatory authority. If you are in the EU, if you believe that we have not complied with applicable data protection laws, including the GDPR, you also have the right to lodge a complaint with the local data protection authority, such as the Data Protection Commission (“DPC”) in Ireland. Please click here for a list of the data protection authorities in the EU member states. If you are in Switzerland, please click here for information on how to contact the Federal Data Protection and Information Commissioner. If you are in the UK, please click here for information on how to contact the Information Commissioner's Office if you would like to lodge a complaint.

To exercise any of the rights described above, please submit a request to us by emailing us at [email protected].

Please note that there may be exceptions to these rights under applicable law.

Only you, or a person that you authorize to act on your behalf, may make a request related to your personal information. The verifiable consumer request must:

  • Provide sufficient information that allows us to reasonably verify you are the person about whom we collected personal information or an authorized representative of such person.
  • Describe your request with sufficient detail that allows us to properly understand, evaluate, and respond to it.

We may be unable to comply with your request or provide you with personal information if you do not take the foregoing actions. Making a request does not require you to create an account with us. We will use personal information provided in a request only to verify your identity or authority to make the request.

How Long We Keep Your Personal Data

We retain personal data for as long as necessary to provide legal services, conduct operations and in accordance with our data retention policies, unless we have deleted personal data in response to a request to delete. We may retain personal data for longer if it is necessary to comply with legal or reporting obligations, resolve disputes, collect fees, or as permitted or required by applicable law. We may also retain personal data in a deidentified or aggregated form so that it can no longer be associated with an individual person. To determine the appropriate retention period for personal data, we consider various factors such as the amount, nature, and sensitivity of the data, the potential risk of unauthorized access, use or disclosure, the purposes for which we process personal data and applicable legal requirements.

When we process personal data for marketing purposes or with your consent, we process the data until you ask us to stop and for a short period after this (to allow us to implement your requests). We also keep a record of the fact that you have asked us not to send you direct marketing or to process your data so that we can respect your request in future.

In general and subject to the relevant provisions of applicable local laws, where we process personal data in connection with the provision of legal services, we keep the data for 10 years from the date the matter is closed.

Where we process personal data to comply with our legal obligations (for example, "know-your-client" information processed for anti-money laundering purposes), we will retain the data for as long as the client has open matters, and for 10 years from the date the last matter is closed, subject to the relevant provisions of applicable local laws.

Security of Your Personal Data

We protect all personal data we process by implementing appropriate technical and organization measures to safeguard such information against unauthorized, unlawful processing or accidental loss, destruction or damage. Among other measures, we store personal data in our possession in a secure operating environment or in physical files whose access is restricted to authorized persons only.

Although we adopt security measures in all areas compatible with the nature of the personal data that we process and with the best practices available in the market, no electronic data processing is entirely safe from technical failures or possible malicious actions by third parties. We constantly evaluate our security measures and update them as necessary in order to keep in line with best practices.

Do Not Track

We do not track visitors of the website over time and/or across third party websites to provide targeted advertising and therefore do not respond to Do Not Track (“DNT”) signals. However, some third party sites do keep track of your browsing activities when they serve you content, which enables them to tailor what they present to you. If you are visiting such sites, your browser allows you to set the DNT signal so that third parties (particularly advertisers) know you do not want to be tracked. You should consult the help pages of your browser to learn how to set your preferences so that websites do not track you.


The California Consumer Privacy Act or “CCPA,” as amended (Cal. Civ. Code § 1798.100 et seq.) provides consumers who reside in California with certain rights with respect to their personal information (referred to elsewhere in this policy as “personal data”).

California’s Shine the Light Law

Under Section 1798.83, we currently do not, and have not in the preceding calendar year, disclosed any personal information with third parties for their direct marketing purposes.
