This Privacy Policy (“Policy”) outlines our practices regarding the collection, use, disclosure, and retention of Personal Information furnished to us.

The Policy outlines the roles and responsibilities of GBM staff members regarding the preservation of the confidentiality of collected personal information. 

In addition to the obligations outlined below concerning Personal Information, we diligently uphold our professional and ethical duties, with a particular emphasis on safeguarding client confidentiality.

If you have any questions regarding your Personal Information held by GBM, you can contact our Privacy Officer, Mtre Nadia Tomassini (hereinafter referred to as the “Privacy Officer”), at the following email address: [email protected]

In this Policy, the term “Personal Information” refers to any information about an identifiable individual, whether directly or indirectly.

Subject to any legal and contractual requirements, you may refuse or withdraw your consent for certain specified purposes at any time by contacting the Privacy Officer. If you refuse or withdraw your consent, we may be unable to provide, or continue to provide, certain services or information that may be beneficial to you. If you provide GBM with Personal Information about another individual, you represent that you have the necessary authority to do so and/or have obtained all necessary consents from that individual to allow us to collect, use, and disclose such Personal Information for the purposes outlined in this privacy policy.

  • To provide our services.
  • To continuously improve our services.

  • To send you information about our activities and professional services offerings, while allowing you to withdraw your consent at any time.
  • To prevent and detect fraud, and continuously assess and improve our security measures.

  • To send you transactional communications, such as an invoice for services rendered.

GBM shares Personal Information with the following individuals/entities:

  • Our service providers;
  • Any government authority, in response to a legal obligation;
  • Parties involved in a case, including experts, professionals engaged in the mandate, opposing parties, and their legal advisors who require access to Personal Information in the context of a legal proceeding or a business transaction.

When GBM shares Personal Information with a person/entity mentioned above, measures are put in place to ensure the confidentiality and security of this information. Only Personal Information that is reasonably necessary for these third parties to fulfill their functions on behalf of GBM or within the scope of a mandate is disclosed.

GBM is committed to obtaining your consent before disclosing or transmitting your Personal Information to a third party not covered by this Policy, except in cases provided for by law.



The security of your Personal Information is our top priority. We employ all necessary means to establish effective security measures to safeguard the confidentiality of your Personal Information.

We have implemented appropriate and reasonable physical, organizational, and technological security measures to protect your Personal Information against loss, theft, unauthorized access, disclosure, copying, or alteration by third parties.

GBM takes the following measures to ensure the protection of your Personal Information:

  • Personal Information collected is stored on a secure server;
  • We have protections in place to help prevent and detect attempts of malware, phishing, ransomware, and intrusions that may compromise the confidentiality of our servers;
  • Our firewall secures the entire network and minimizes external intrusions;
  • Our offices are equipped with security features, including individual access cards for each employee, to ensure the confidentiality of our records and integrity of our physical servers;
  • Every employee is provided with an exclusive computer and a unique password for server access as an authentication method for added security.



Your Personal Information is retained for as long as it is necessary for the purposes stated in this Policy, subject to any legal retention period requirements.

Once the objectives for which your Personal Information was collected have been achieved and after any applicable legal retention period has expired, GBM will proceed with the destruction or anonymization of this data.

We may retain certain information for purposes of analysis, accounting, maintaining accurate financial records, fraud prevention, fee recovery, compliance with our ethical obligations, enforcement of terms of use, safeguarding the integrity of the website or its users, or for other reasons permitted by law. Furthermore, if any of your Personal Information has been shared with third parties with your consent, their use and retention will be subject to the policies of those third parties, and GBM shall not be held responsible in any way.
