How we obtain your details

We will also hold information about your details so that we can respect your preferences for being contacted by us.

We will contact these individuals if we believe there is a legitimate interest in attending relevant Hippocampus Media Ltd marketing, media, advertising and technology events. We will only contact you if we believe that the legitimate interest does not infringe your own personal rights.

We may also work with a trusted external partner to ensure that our data is up-to-date.

You may opt out of our communications at any time and choose not to be contacted by us again at any time.

Building profiles of customers and attendees

Hippocampus Media may use information you have provided us with about your business interests, priorities and challenges, as well as your business type and job function to ensure that we provide more relevant and targeted communications based on your interests.

We do not knowingly take payments from minors.

As a parent/guardian of any child under the age of 18, we recommend that you monitor the online and offline activities of your child/children. If your child discloses information without your consent, the risk of you receiving unsolicited messages will increase. We discourage anyone under the age of 18 from submitting information to us without the consent of a parent/guardian.

3. Legitimate interest

Hippocampus Media Ltd has several lawful reasons for processing your personal information, including legitimate interest. Legitimate interest enables us to process your information so long as we have a genuine and legitimate reason to believe that you may be interested in and benefit from hearing about our industry events, products, insights and services, and we do not harm your rights and interests in doing so.

Legitimate interest may apply to our direct marketing activities; distribution of our own or partners’ insights and reports; access to event content such as presentations; tools such as our networking app; location-based data, invitations to events and private functions; improving the relevancy and experience of our events; letting you know about speaking, sponsorship and exhibition opportunities.

Our function is to provide events, content and digital experiences where the world’s top marketers, advertising agencies, publishers and tech firms can come together to learn, explore trends, discover innovations, build relationships, boost knowledge, enhance career prospects and do business.

We can reasonably expect that practitioners in the marketing, advertising, media, technology and other related industries may have a genuine interest in the speakers, networking, workshops and business development opportunities we provide. We will process your information under legitimate interest to provide industry practitioners with the up-to-date event information, relevant opportunities, offers and reports. We consider this to be legitimate interest. You may opt out of our communications at any time and we will delete your data permanently if you do not wish to hear from us. You can do this by contacting

Our interest

Below are some examples of why we would use legitimate interest to communicate with you:

Direct marketing - we will send you email, social and postal marketing to let you know key event information such as speaker updates, ticket information, access to our networking app, speaking, sponsorship and exhibition opportunities, useful content such as reports and whitepapers, complimentary passes to our events and partner events, our campaigns, event preferences, dietary information, content and topic/product interests.

Ordering online - we will need to collect your personal information to process an order such as a ticket or complimentary event pass. Typically this will include your name, job title, company, phone number, postal address and email address.

Event choices - if you have registered for one of our events, we may need to ask you about your dietary, workshop/seminar, stream, private event and dinner choices.

Personalisation - we may ask you about your business priorities, topic interests/speaker and event preferences to improve our products/services and make your experience of our marketing/communications more relevant. We will also use this information to provide event attendees with our networking app. Our app enables individual attendees to network based on shared interests and relevance (business type, key interests, marketing challenges etc).

Partner content - from time to time, we will work with external partners to provide you with free access to insights on the marketing, advertising and technology industry such as white papers and reports. In order to provide access, we may need to collect your name, job title, company, phone number and email address and share this information with a trusted partner. You may opt out at any time.

Your best interest - we will process your information to protect you against fraud when purchasing a product or service on our website and to ensure that our websites and systems are secure.

Your interests - When we process your personal information for our legitimate interests, we will consider and balance any potential impact on you and your rights under data protection and any other relevant law. Our legitimate business interests do not automatically override your interests – we will not use your personal data for activities where our interests are overridden by the impact on you (unless we have your consent or are otherwise required or permitted to by law). Please see our section on ‘Your rights’.

Remember, you can unsubscribe from our marketing communications (there is a link on our emails to do this) or ask to be removed from our database by emailing

4. Sharing your information

In order to run viable events with targeted networking opportunities and a visible list of attendees, we may publish and/or share your name, job title, company and interests when you have registered to attend or participate in our events. This may take place before, during or after the event and will be shared with confirmed and prospective attendees, sponsors, exhibitors and other reputable partners. When you register for our events, we will ask you to download our mobile and/or desktop app which includes your e-ticket. When you register, attend or view our content online, we reserve the right to share your data with 3rd parties including but not limited to sponsors, exhibitors, advertisers and other partners, who may then contact you directly via email, phone, direct mail, social media or any other channel. When you download our app, your name, job title and company are visible to other event attendees (as they would be if we distributed printed delegate lists). You may receive meeting requests and/or messages from other attendees, which you may decide to accept or decline.

We will be clear about what happens with your data when you register to attend or participate in our events.

If you decide to download a report, white paper or other form of ‘gated’ content we have distributed on behalf of a partner or sponsor, we will share this information with the individual partner. This may include your name, job title, company and business email address. When you download such free content, we will always be clear that we plan to use your information in this way.

We may also need to share your information with key suppliers in order to fulfil orders you make. Examples include mailings (post and electronic), processing payments and answering customers’ questions about products and services.

If we merge with another organisation to form a new entity, information may be transferred to the new entity.

5. Retaining your information

Personal data processed for any purpose or purposes shall not be kept for longer than is necessary for that purpose or those purposes. We will periodically review the length of time that we keep your data for.

If you let us know that you would like to no longer like to receive communications from us, we will keep some basic information about you to avoid sending you unwanted content in the future and so that we do not accidentally duplicate information.

We may also contact you about future events and launches based on your attendance or engagement at MAD//Fest or when we consider there to be legitimate interest in hearing from us about specific products and services.
