4. Personal data provided by or about third parties

If you share with us information regarding any other individual (e.g. your employees, colleagues, ultimate beneficial owners, relatives, etc.), you warrant (and shall procure that any member of your group/affiliates warrants) that the personal data to be transferred has been collected and processed in accordance with the requirements of the Data Protection Legislation and that the further processing and transfer of personal data by Deloitte as set forth in this privacy notice is admissible by the Data Protection Legislation. Particularly you warrant that prior to any transfer of this personal data you have provided any necessary notice and collected any necessary permission from affected individuals, verified technical and organisational measures and do all such other things as are required under the Data Protection Legislation in order to disclose personal data to Deloitte, Deloitte Network, its Subprocessors, and let them process and transfer this personal data outside Switzerland and the EEA for the services.

5. How we use your personal data

We process information about you and/or your business to enable us and other members of the Deloitte Network to provide our services to you or our clients, and to meet our legal or regulatory obligations.

Some of your personal data may be used for other business purposes. Below are some examples.

Use of personal data to provide services to our clients

  • you;
  • other third parties or other members of the Deloitte Network;
  • our service providers; or
  • competent authorities.

We may also use your personal data to conduct due diligence checks relating to the services.

Because we provide a wide range of services to our clients or other third parties, the way we use personal data in relation to our services also varies. For example, we might use personal data about:

  • a client’s employees to help those employees manage their tax affairs when working overseas;
  • a client’s employees and customers in the course of conducting an audit (or similar activity) for a client; or
  • a client to help them complete a tax return.

Use of personal data for other activities that form part of the operation of our business

We may also use your personal data in connection with:

  • legal or regulatory requirements;
  • requests and communications from competent authorities;
  • client account opening and other administrative tasks;

  • relationship management, which may involve:

(a) sending you thought leadership or details of our products and services;

(b) contacting you for feedback on services;

(c) sending you event invitations; and

(d) other marketing or research purposes;

  • recruitment and business development, which may involve:

(a) the use of testimonials from a client’s employees as part of our recruitment and business development materials (with that employee’s permission); and

(b) the use of third-party data sources to help us verify and improve the information we hold about key business relationships with individuals;

  • services we receive from our professional advisors, such as lawyers, accountants and consultants;
  • investigating or preventing security incidents; or
  • protecting our rights and those of our clients.

Use of personal data collected via our Website

In addition to the above, we may also use your personal data collected via our Website:

  • to manage and improve our Website;
  • to tailor the content of our Website to give you a more personalised experience;
  • to draw your attention to information about our products and services that may be of interest to you; or
  • to manage and respond to any request you submit through our Website.

The processing regarding website use is based on our legitimate interest to operate and secure our website and our services, in particular for security reasons to ensure the stability and integrity of our systems (Art. 6 para. 1 lit. f GDPR). In addition, we may perform basic web analysis based on our legitimate interest (Art. 6 para. 1 lit. f GDPR) to optimize the website regarding usability and to gain insights about the use of our website and services. The collected data will not be merged with other personal data or disclosed to third parties. Enhanced web analysis using cookies is, within the scope of applicability of the GDPR, based on your consent (Art. 6 para. 1 lit. a GDPR).

6. The legal grounds we use for processing personal data

We are required by law to set out in this privacy notice the legal grounds on which we rely in order to process your personal data. We rely on one or more of the following lawful grounds:

  • you have explicitly agreed to us processing your information for a specific reason;
  • the processing is necessary to perform the agreement we have with you or to take steps to enter into an agreement with you;
  • the processing is necessary for compliance with a legal obligation we have such as keeping records for tax purposes or providing information to a public body or law enforcement agency; or
  • the processing is necessary for the purposes of a legitimate interest pursued by us or a third party, which might be:

(a) to provide our services to you or our clients and other third parties and ensure that our client engagements are well-managed;

(b) to prevent fraud;

(c) to protect our business interests;

(d) to ensure that complaints are investigated;

(e) to evaluate, develop or improve our services or products; or

(f) to keep you or our clients informed about relevant products and services and provide you with information, unless you have indicated at any time that you do not wish us to do so.

To the extent that we process any special categories of data relating to you for any of the purposes outlined above, we will do so because:

  • you have given us your explicit consent to process that data;
  • we are required by law to process that data in order to ensure we meet our ‘know your client’ and ‘anti-money laundering’ obligations (or other legal obligations imposed on us);
  • the processing is necessary to carry out our obligations under employment, social security or social protection law;
  • the processing is necessary for the establishment, exercise or defence of legal claims; or
  • you have made the data manifestly public.

Please note that in certain circumstances it may be still lawful for us to continue processing your information even where you have withdrawn your consent, if one of the other legal bases described above is applicable.

7. Sharing your personal data

In connection with any of the purposes outlined in the “How we use your personal data?” section above, we may disclose details about you to:

  • other members of the Deloitte Network or third parties that provide services or online platforms to us and/or the Deloitte Network;
  • competent authorities (including tax authorities, courts and authorities regulating us and other members of the Deloitte Network); in Switzerland and abroad, if we are legally obliged or entitled to such disclosure or if it appears necessary to protect our interests);
  • your employer and/or its advisers, or your advisers;
  • anyone to whom we may transfer our rights and/or obligations under the Terms of Use;
  • any other person or organisation after a restructure, sale or acquisition of any member of the Deloitte Network, as long as they use your information for the same purposes we did;
  • credit reference agencies or other organisations that help us make credit decisions and reduce the incidence of fraud;
  • service providers (e.g. IT service providers, business information providers, newsletter service providers, marketing and event management service providers, etc.);
  • legal and professional advisors, including accountants and auditors;
  • other third parties that reasonably require access to personal data relating to you.

Our Website hosts various blogs, forums, wikis and other social media applications or services that allow you to share content with other users (collectively “Social Media Applications”). Any personal data that you contribute to these Social Media Applications can be read, collected and used by other users of the application. We have little or no control over these other users, so any information you contribute to these Social Media Applications might not be handled in line with this privacy notice.

8. Transferring your personal data

Information we hold about you may be transferred outside Switzerland, to the countries that offer adequate data protection pursuant to the Data Protection Legislation, e.g. to the EEA, and under certain circumstances, we may also transfer data to the countries which do not offer adequate data protection (e.g. to US or India) if necessary for the respective processing purpose, e.g.:

  • where we do business;
  • which are linked to your engagement with us;
  • from where you regularly receive or transmit information; or
  • where our subprocessors or third parties conduct their activities.

These countries may have less stringent privacy laws than we do, so any information they hold can become subject to their laws and disclosure requirements, including disclosure to governmental bodies, regulatory agencies and private persons. In addition, a number of countries have agreements under which information is exchanged with other countries for law enforcement, tax and other purposes.

When we, or our permitted third parties, transfer your personal data, we will assure the transfer is secured by appropriate safeguards such as the EU Standard Contractual Clauses, or based on a statutory exemption (e.g. if you have given your consent to the transfer) and we will impose contractual obligations on the recipients of that data to protect your personal data to the standard required by the Data Protection Legislation.

If we transfer your personal data outside Switzerland in other circumstances (for example, because we have to by law), we will make sure it remains adequately protected.

We may share non-personal, anonymised and aggregated information with third parties for several purposes, including data analytics, research, submissions, thought leadership and promotional activity.


9. Protecting your personal data

We use a range of measures to ensure we keep your personal data secure, accurate and up to date. These include:

  • education and training to relevant staff to ensure they are aware of our privacy obligations when handling personal data;
  • administrative and technical controls to restrict access to personal data to a ‘need to know’ basis;
  • technological security measures, including fire walls, encryption and anti- virus software; and
  • physical security measures, such as security passes to access our premises.

The transmission of data over the internet (including by e-mail) is never completely secure. So although we use appropriate measures to try to protect personal data, we cannot guarantee the security of data transmitted to us or by us.

10. How long we keep your personal data for

We seek to ensure that we only keep your personal data for the longest of:

  • the period necessary for the relevant activity or services;
  • any retention period that is required by law; or
  • the period in which litigation or investigations might arise in respect of the services.

11. Your rights

  • obtain confirmation that we are processing your personal data and request a copy of the personal data we hold about you;
  • be informed about the processing of your personal data (i.e. for what purposes, what types, to what recipients it is disclosed, storage periods, any third party sources from where it was obtained, confirmation of whether we undertake automated decision-making, including profiling, and the logic, significance and envisaged consequences);
  • ask that we update the personal data we hold about you, or correct such personal data that you think is incorrect or incomplete;
  • ask that we delete personal data that we hold about you, or restrict the way in which we use such personal data; withdraw consent to our processing of your personal data (to the extent such processing is based on previously obtained consent);

  • ask us to stop or start sending you marketing messages at any time by using the contact details in section 13 below; and
  • object to our processing of your personal data.

If you would like to access or see a copy of your personal data, you must ask us in writing. We will endeavour to respond within a reasonable period, and in any event within one month in line with Data Protection Legislation. We will comply with our legal obligations as regards your rights as a data subject.

To help us ensure that your information is up to date, let us know if any of your personal details change using the contact details set out in section 13.

You may also use the contact details in section 13 if you wish to make a complaint relating to your privacy.

12. Sending you marketing information

We and other members of the Deloitte Network may process marketing data for marketing purposes and relationship management, for example to send personalized advertising for our services and products, e.g. in the form of newsletters or other regular contacts either in person, via e-mail or other electronic form, by phone or any other communication channel for which we have contact information from you and by any other marketing means (e.g. through events, fairs, etc.). We do so based on our legitimate interest to keep you informed about our products and services (Art. 6 para. 1 lit. f GDPR), to the extent permitted by applicable marketing regulations, or, where required, based upon your consent in this regard (Art. 6 para. 1 lit. a GDPR).
