We will however respect your wishes not to receive marketing communications or to stop receiving them at any point in time. You can opt out from receiving these at any time by using the unsubscribe links or instructions included at the bottom of our emails.

Please note that we will continue to send you service-related communications regardless of any opt-out request regarding marketing communications.

Sensitive data

By “sensitive data” or “special categories data” we mean the various categories of personal data identified by data privacy laws as requiring special treatment, including in some circumstances the need to obtain explicit consent from you. These categories include racial or ethnic origin, political opinions, religious, philosophical, or other similar beliefs, membership of a trade union, physical or mental health, biometric or genetic data, sexual life or orientation, or criminal convictions and offences (including information about suspected criminal activities).

We do not generally seek to collect sensitive data either through our website or otherwise. If we do seek to collect such data, we will do this in accordance with data privacy law requirements.

Who we share your personal information with

We may share your personal information with people within Quant and other companies of the Quant group who need to have access to it for business or legal reasons, e.g. in order to provide customer support or to carry out an administrative function such as processing an invoice.

We may also share your personal information with certain third parties in connection with the operation of our business, including our service providers, professional advisers, and public and government authorities.

In particular, we routinely share personal information with:

  • third-party service providers that provide services to us, including billing, payment processing, customer service, email deployment, advertising and marketing, security, and performance monitoring, maintaining, or servicing accounts, processing or fulfilling orders and transactions, verifying customer information, hosting, auditing, and website analytics and data processing; and
  • for other business purposes described in this privacy policy or for any other purpose disclosed to you at the time we collect the information or pursuant to your consent.

We will share your personal information with third parties only if we are satisfied that they take appropriate action to protect your personal information. These third parties may be based in other countries and before we transfer your personal information, we will make sure that we have taken the necessary steps to ensure that your personal information will be given adequate protection as required by applicable data privacy laws (see section on ‘Transfers outside the UK and European Economic Area (EEA)’ below).

We may also need to share your personal information with our legal, information security and other third party advisors from time to time in the following circumstances:

  • with our legal, information security and other advisors to protect and defend the legal rights, safety, and security of Quant, our group companies, users, or the public, including to protect against fraud and malicious activity; and
  • in connection with a proposed corporate transaction, such as a merger or acquisition.

Law enforcement requests

At Quant we are committed to protecting the privacy and other rights of our users as well as the safety and integrity of the services we provide. See our Acceptable Use Policy for details. As such where appropriate we co-operate with law enforcement bodies to promote safety, protect against misuse of our services and otherwise assist their enquiries in connection with suspected criminal offences and/or other contraventions of applicable law.

When we receive a lawful request from a law enforcement body seeking the disclosure of the personal information of a user of one of our websites or services, we will first review and establish the validity of the request. If it is a valid request, our policy is to co-operate with the requesting law enforcement body unless there is a good reason not to do so. If Quant decides to share a user’s personal information in response to such a request, we will first ensure we have a lawful basis to do so.

Keeping your personal information secure

We have implemented technical and organisational measures to safeguard your personal information and help prevent unauthorised access. These measures include:

  • applying encryption methods to your personal information both when we store your information on our internal databases and when we need to transfer it to a third party (or internally);
  • ensuring we have appropriate firewalls in place;
  • requiring our staff to comply with our data protection policies; and
  • restricting access to your personal information on a need-to-know basis.

We also have procedures in place to deal with any suspected data breach. If you suspect any misuse or loss or unauthorised access to your personal information, please let us know immediately by contacting us via this e-mail address:

How long will your personal information be kept?

We will keep your personal information only for as long as we need it to fulfil the purposes for which the information was collected unless legal or regulatory obligations require us to keep it for longer. When we no longer have a need to keep your personal information, we will delete it or anonymise it.

Please note that when you unsubscribe or opt out from a marketing communication, we may need to keep a record of your email address to ensure we do not send you marketing emails in the future.

Data subject rights

You generally have the following rights:

  • Right to access: the right to request copies of the information we hold about you at any time, or that we modify, update, or delete such information. If we provide you with access to the information we hold about you, we will not charge you for this unless your request is “manifestly unfounded or excessive.” Where we are legally permitted to do so, we may refuse your request. If we refuse your request, we will tell you the reasons why.
  • Right to correct (also known as rectification): the right to have your information rectified if it is inaccurate or incomplete.
  • Right to erase (also known as the right to be forgotten): the right to request that we delete your information.
  • Right to restrict our use of your information: the right to “block” us from using your information or limit the way in which we can use it.
  • Right to portability: the right to request a copy (in a structured, commonly used and machine readable format) of your information or that we transfer such information to another data controller.
  • Right to object to use: the right to object to our processing of your information including where we use it for our legitimate interests.

To make enquiries, exercise any of your rights set out above, or withdraw your consent to the processing of your personal information (where consent is our legal basis for processing your information), please contact us via this e-mail address:

You have the right to complain to an information authority about our collection and use of your information. For the UK, this is the Information Commissioner’s Office (ICO). The ICO’s contact details can be found on their website.

Transfers outside the UK and the European Economic Area (EEA)

Countries outside of the UK and the EEA have different data protection laws, some of which may provide lower levels of protection for personal information.

Personal information which we collect from you may be stored and processed in and transferred to countries outside of the UK and the EEA. For example, if our servers are located in a country outside the UK or the EEA or one of our service providers is situated in a country outside the UK or the EEA. We also share information with our group companies, some of which are located outside the UK and EEA.

When we engage third parties to process your personal information on our behalf, we will contractually require them to handle your personal information appropriately and in accordance with applicable data privacy laws.

Wherever we transfer your information outside the UK and the EEA we will take legally required steps to ensure that appropriate safeguards are in place to protect it. You may contact us to request an explanation of the basis under which we have transferred your personal information and, where relevant, request a copy of the legal safeguards in place by emailing:
