Sending marketing communications

Our marketing communications include information about the book and subjects that relate to it, updates about what we are doing, and potential events. Occasionally, we may include information from partner organisations or organisations who support us in these communications. We operate an ‘opt-in only’ communication policy with the exception of standard administrative communications. We will only send marketing communications to you if you have explicitly stated that you are happy for us to do so through direct communication or social media and other platforms as appropriate.

We may use information you have given us directly to tailor our communications with you about future activities.

Managing your contact preferences

We make it easy for you to tell us how you want us to communicate, in a way that suits you. Our forms have clear information on how to opt out when we send you marketing. If you do not want to hear from us, that’s fine, and you can let us know when you provide your data or contact us by emailing us at webmaster@geometrylastsupper.com.

Legal basis for processing

Data protection laws mean that each use we make of personal information must have a “legal basis”. The relevant legal bases are set out in the GDPR and in current UK data protection legislation including the Data Protection Act 2018 and the Privacy and Electronic Communications (EC Directive) Regulations 2003.

• Specific consent Consent is where we ask you if we can use your information in a certain way, and you agree to this (for example when we send you marketing material via post, phone, text or e-mail). Where we use your information for a purpose based on consent, you have the right to withdraw consent for any future use of your information for this purpose at any time by emailing us at webmaster@geometrylastsupper.com.

• Legal obligation We have a basis to use your personal information where we need to do so to comply with one of our legal or regulatory obligations. For example, in some cases we may need to share your information with our various regulators such as the Information Commissioner, or to use information we collect about you for due diligence or ethical screening purposes.

• Performance of a contract / take steps at your request to prepare for entry into a contract We have a basis to use your personal information where we are entering into a contract with you or performing our obligations under that contract. Examples of this would be if you are buying something from us.

• Vital interests We have a basis to use your personal information where it is necessary for us to protect life or health. For instance, if there is an emergency impacting individuals at one of our events, or a safeguarding issue which required us to contact people unexpectedly or share their information with emergency services.

• Legitimate interests We have a basis to use your personal information if it is reasonably necessary for us (or others) to do so and in our/their “legitimate interests”. This is providing that we use the information fairly and it does not unduly impact your rights.

We only rely on legitimate interests where we consider that any potential impact on you (positive and negative), how intrusive it is from a privacy perspective and your rights under data protection laws do not override our interests in us using your information in this way.

We do not collect sensitive personal information (for example, information about your race or ethnic origin, your religious or political beliefs, or your health).

How we keep your information safe

We use Mailchimp as our newsletter platform. By subscribing, you acknowledge that your information will be transferred to Mailchimp for processing. Learn more about Mailchimp's privacy practices here.

How long we keep your information for

We have specific criteria to determine how long we will retain your information for, which are determined by legal and operational considerations.

Sharing your information with other organisations

We will never sell or rent your information to third parties for marketing purposes. However, we may disclose your information to third parties in connection with the other purposes set out in this policy. These third parties may include business partners, suppliers, sub-contractors, IT service providers etc. who may process information on our behalf.

Where we are under a legal or regulatory duty to do so, we may disclose your details to the police, regulatory bodies or legal advisors, and/or, where we consider this necessary, to protect the rights, property or safety of Raphaël Mouterde, its personnel, visitors, users or others.

Keeping your information up to date

We really appreciate it if you let us know if your contact details change. If we are informed by reliable sources (such as partnership organisations or official institutions) that your details have changed, we will update your details so we can stay in touch, provided that you have opted in to hearing from us. We only use sources where we have documented consent from partners who have confirmed that you have been informed of how your information may be shared and used. This activity also prevents us from having duplicate records and out of date preferences, so that we do not contact you when you have asked us not to.

We’re committed to putting you in control of your data and you are free at any time to let us know if you do not want us to check your personal details against other publicly available sources. You can do that by emailing us at webmaster@geometrylastsupper.com.

Your rights

Under UK data protection law, you have rights over personal information that we hold about you. We have summarised these below:

• Right to access your personal information You have a right to request access to the personal data that we hold about you and to other supplementary information including the reason why we use your personal data and how long we will keep it for. You also have the right to request a copy of the information we hold about you, and we will provide you with this unless legal exceptions apply.

• Right to have your inaccurate personal information corrected You have the right to have inaccurate or incomplete information we hold about you corrected. If you believe the information we hold about you is inaccurate or incomplete, please provide us with details and we will investigate and, where applicable, correct any inaccuracies.

• Right to restrict use of your personal information You have a right to ask us to restrict the processing of some or all of your personal information in the following situations: if you have told us that some information we hold about you is not correct and we are in the process of verifying the accuracy of the information; we are not lawfully allowed to use it; you need us to retain your information in order for you to establish, exercise or defend a legal claim; or you believe your privacy rights outweigh our legitimate interests to use your information for a particular purpose and you have objected to us doing so.

• Right to erasure of your personal information You may ask us to delete some or all of your personal information and in certain cases, and subject to certain exceptions, you have the right for this to be done.

• Right for your personal information to be portable If we are processing your personal information (1) based on your consent, or in order to enter into or carry out a contract with you, and (2) the processing is being done by automated means, you may ask us to provide it to you or another service provider in a machine-readable format.

• Right to object to the use of your personal information If we are processing your personal information based on our legitimate interests or for scientific/historical research or statistics, you have a right to object to our use of your information.

If we are processing your personal information for direct marketing purposes, and you wish to object, we will stop processing your information for these purposes as soon as reasonably possible.

If you want to exercise any of the above rights, please email us at webmaster@geometrylastsupper.com. We may be required to ask for further information and/or evidence of identity. We will endeavour to respond to your request within one month of receipt of your request, however if we are unable to do so we will contact you with reasons for the delay.

Please note that exceptions apply to a number of these rights, and not all rights will be applicable in all circumstances. For more details we recommend you consult the guidance published by the UK’s Information Commissioner’s Office.


If you are unhappy with any aspect of how we are using your personal information we would like to hear about it, so please email webmaster@geometrylastsupper.com. We appreciate the opportunity this feedback gives us to learn and improve.

You also have the right to lodge a complaint about any use of your information with the Information Commissioner’s Office, the UK data protection regulator.
