CancerGreen is a personalised nutrition and lifestyle support service for people living with cancer. CancerGreen is wholly owned and operated by Link Genes Ltd.

This Privacy Policy explains how we collect, use, store, and protect your personal information when you visit our website, contact us, complete a questionnaire, purchase or use our services, or interact with CancerGreen in any way.

CancerGreen is owned by:

Link Genes Ltd
Company registration no: 16045198
86-90 Paul Street, London, EC2A 4NE, UK

For the purposes of UK data protection law, Link Genes Ltd is the “data controller” for the personal information we collect and use through CancerGreen.

Depending on how you use CancerGreen, we may collect the following types of information:

This may include your name, email address, telephone number, postal address, and communication preferences.

This may include information about your cancer diagnosis, treatment plan, symptoms, medications, allergies, dietary habits, lifestyle, physical activity, sleep, alcohol intake, smoking status, goals, and preferences.

If you choose to use nutrigenomic testing, we may process information relating to your genetic profile as it relates to nutrition, metabolism, inflammation, vitamin requirements, weight management, lipid metabolism, and other diet-related factors.

If you choose optional microbiome testing, we may process information relating to gut health, bacterial diversity, digestive function, inflammation markers, and related dietary insights.

If you purchase a service, we may collect payment-related information. Payment card details may be processed by a third-party payment provider and may not be stored directly by us.

We may collect information such as your IP address, browser type, device type, pages visited, time spent on the site, referral source, and cookie preferences.

If you contact us, we may keep records of emails, forms, telephone notes, consultation notes, or other correspondence.

Some of the information we collect is classed as “special category data” under UK data protection law. This includes health data and genetic data. This type of information requires extra protection because it is sensitive.

We only collect and use this information where it is necessary to provide the CancerGreen service, where you have chosen to provide it, and where we have a lawful basis and special category condition under UK GDPR.

We may use your personal information to:

• Provide CancerGreen services to you
• Review your questionnaire responses
• Arrange nutrigenomic or microbiome testing, where selected
• Prepare your personalised CancerGreen report
• Provide nutrition and lifestyle guidance
• Arrange consultations with nutritionists or other service providers
• Respond to your enquiries
• Process payments and manage orders
• Improve our website, services, reports, and customer experience
• Maintain accurate records
• Comply with legal, regulatory, tax, accounting, and insurance obligations
• Protect the safety, security, and integrity of our services
• Manage complaints, disputes, or legal claims

CancerGreen is not a cancer treatment, diagnostic service, or replacement for oncology care. Information collected through CancerGreen is used to provide supportive nutrition and lifestyle guidance alongside your existing medical care.

Under UK GDPR, we must have a lawful basis for using your personal information. Depending on the circumstances, we may rely on one or more of the following lawful bases:

We may process your information where it is necessary to provide the CancerGreen service you have requested.

We may rely on your consent for certain activities, including processing genetic or microbiome testing information, sending certain marketing communications, or collecting optional information.

Because health and genetic information are special category data, we may ask for your explicit consent before processing this information as part of the CancerGreen service.

We may process information where we are required to do so by law, including tax, accounting, regulatory, or legal reporting obligations.

We may process information where it is necessary for our legitimate business interests, provided your rights and interests do not override those interests. This may include improving services, managing enquiries, protecting our business, and maintaining website security.

We may share your information with carefully selected third parties where necessary to provide our services or operate our business. These may include:

• Nutrigenomic testing laboratories
• Microbiome testing laboratories
• Nutritionists, dietitians, or clinical support professionals involved in your service
• IT, website, hosting, email, and cloud service providers
• Payment processors
• Customer support or booking systems
• Professional advisers, including lawyers, accountants, insurers, and auditors
• Regulators, public authorities, or law enforcement where legally required

We only share information that is necessary for the relevant purpose. Where third parties process information on our behalf, we require them to protect it appropriately and use it only for agreed purposes.

Some of our service providers, laboratories, or technology platforms may be based outside the UK. Where your personal information is transferred outside the UK, we will take steps to ensure appropriate safeguards are in place, such as adequacy regulations, standard contractual clauses, or equivalent protections required by law.

We take appropriate technical and organisational measures to protect your personal information. These may include:

• Limiting access to authorised personnel
• Using secure systems and passwords
• Using encryption where appropriate
• Reviewing supplier security measures
• Keeping records of processing activities
• Training relevant staff and contractors
• Using secure methods for storing and transferring sensitive information

No website, email system, or digital platform can be guaranteed to be completely secure. However, we take the protection of health, genetic, and microbiome information seriously.

We keep personal information only for as long as necessary for the purposes described in this Privacy Policy.

The retention period may depend on the type of information, the service provided, legal or regulatory requirements, insurance requirements, and whether the information may be needed to manage complaints or legal claims.

Where information is no longer needed, we will delete it, anonymise it, or securely archive it.

Under UK data protection law, you may have the right to:

• Ask for a copy of the personal information we hold about you
• Ask us to correct inaccurate or incomplete information
• Ask us to delete your information in certain circumstances
• Ask us to restrict how we use your information
• Object to certain types of processing
• Withdraw consent where we rely on consent
• Ask for your information to be transferred to another provider, where applicable
• Complain to the Information Commissioner’s Office

To exercise your rights, please contact us at:

info@linkgenes.com

We may need to verify your identity before responding to your request.

Where we rely on your consent or explicit consent, you may withdraw it at any time by contacting us.

If you withdraw consent, this will not affect the lawfulness of processing that took place before consent was withdrawn. It may also mean that we are unable to continue providing some or all of the CancerGreen service to you.

We may send you updates about CancerGreen, related services, educational content, or relevant offers where permitted by law.

You can opt out of marketing communications at any time by using the unsubscribe link in our emails or by contacting us directly.

We will not sell your personal information to third parties for marketing purposes.

Our website may use cookies or similar technologies to improve site functionality, understand how visitors use the site, and support website performance.

Where required, we will ask for your consent before using non-essential cookies.

You can manage cookies through your browser settings or any cookie preference tools available on our website.
