We take care to ensure that our marketing activities comply with all applicable EEA and UK legal requirements. In some cases, this may mean that we ask for your consent in advance of us or MMC Affiliates sending you marketing materials.

In all cases, you can always opt out of receiving marketing communications from us or MMC Affiliates, at any time. We will always provide an option to unsubscribe or opt-out of further communication on any electronic marketing communications sent to you or you may opt out by contacting us as set out below.

(6) How we protect your personal information

Security over the internet

We maintain commercially reasonable physical, electronic and procedural safeguards to protect your personal information in accordance with data protection legislative requirements.

All personal information that we hold is stored on our, or our third party suppliers’, secure servers and only accessed and used subject to our security policies and standards.

Export outside the EEA and the United Kingdom

Your personal information may be accessed by our staff, affiliates or suppliers in, transferred to, and/or stored at, a destination outside the country in which you are located, whose data protection law may be of a lower standard than those in your country.  We will, in all circumstances, safeguard personal information as set out in this Privacy Notice.

Where we transfer personal information from inside the EEA or the United Kingdom to outside the EEA or United Kingdom, we are required to take specific measures to safeguard the relevant personal information.  Certain countries outside the EEA and the United Kingdom have been approved by the European Commission or the United Kingdom Government  as providing essentially equivalent protections to EEA or United Kingdom data protection laws and therefore no additional safeguards are required to export personal information to these jurisdictions (see the full EEA list here). In countries which are not subject to this approval, we will establish legal grounds justifying such transfer, such as MMC Binding Corporate Rules (see here for MMC’s BCR Summary), model contractual clauses, or other legal grounds permitted by applicable legal requirements.

Please contact us as set out below if you would like to see a copy of the specific safeguards applied to the export of your personal information.

Storage Limitation

We will retain your personal information for as long as is necessary for the processing purpose(s) for which it was collected and any other permitted linked purpose (for example where we are required to retain personal information for longer than the purpose for which we originally collected it in order to comply with certain regulatory requirements, to defend legal claims, respond to complaints or to ensure that we have an accurate record of the service that we have provided). Our retention periods are based on business needs and your information that is no longer needed is either irreversibly anonymised (and the anonymised information is retained) or securely destroyed.

(7) Your Rights

Under certain conditions, you have the right to ask us to:

a) provide you with further details on the use we make of your information;

b) provide you with a copy of information that you have provided to us;

c) update any inaccuracies in the personal information we hold; and

d) delete any personal information that we no longer have a lawful ground to use,

and to:

e) object to any processing that we justify on the basis of our “legitimate interests” unless our reasons for undertaking that processing outweigh any prejudice to your data protection rights;

f) object to direct marketing (including any profiling for such purposes);

g) restrict how we use your information whilst we consider your inquiry; and

h) where processing is based on consent, you have the right to withdraw your consent by contacting us at the contact details below or as indicated when consent was given.

You can exercise these rights by contacting us as set out in the “contacting us” section below. Your exercise of these rights is subject to certain exemptions to safeguard the public interest (e.g.  the prevention or detection of crime) and our interests (e.g. the maintenance of legal privilege).  If you exercise any of these rights we will check your entitlement and respond in most cases within a month.

If you are not satisfied with our use of your personal information or our response to any exercise of these rights you have the right to complain to the data protection regulator in your country.
