Quick-Reference Summary

This summary is for convenience. The full terms below are legally binding.

1. About Us and These Terms

DEPH LABS LTD ("DEPH LABS", "we", "us", "our") is a private limited company incorporated in England and Wales, company number 16613109, registered office at Unit 10 Fairfield Industrial Estate, Gwaelod-Y-Garth, Cardiff, Wales, CF15 8LA.

We operate www.deph.uk and a mobile application (the “App”) marketed under the product name “Engne” — the World’s First Male-Only Epigenetic Performance and Longevity Platform. Engne is a product name of DEPH LABS LTD. The Engne app is distributed on the Apple App Store and Google Play Store by Ummu Hub Ltd (Company No. 16624424), registered in England and Wales, which is the registered developer account holder for both stores. DEPH LABS LTD owns and operates the Engne app and is solely responsible for all services, content, and the legal obligations set out in these Terms. Our Services are designed for adult men and male physiology. Our Services comprise:

• DNA and Epigenetic Test Kits — saliva-based testing analysing genetic traits and epigenetic markers relevant to men's health and performance across Performance, Fitness, Longevity, Hair Health, and Hormonal Health categories.
• Re-Test Kits — repeat epigenetic testing to track changes in your biological age over time.
• Personalised Supplements — performance and longevity formulations built from your DNA and epigenetic results, including Performance, Longevity, Hair Health, and Hormonal Support formulations.
• Engne AI Health Coach — an AI wellness coach trained specifically on male genetics, epigenetics, and hormonal patterns.
• Performance Subscription — a subscription service providing ongoing access to testing, insights, and supplement protocols.

These Terms of Service ("Terms") govern your use of our website, App, and all Services. By purchasing a product, creating an account, or using any part of our Services, you agree to these Terms. If you do not agree, you must not use the Services.

The following documents form part of our agreement with you:

• Our Privacy Policy (www.deph.uk/pages/privacy-policy), incorporated by reference. The Privacy Policy includes our full account deletion procedure at Section 11a.
• Our Data Deletion Policy ( www.deph.uk/pages/engne-app-account-deletion-process), incorporated by reference.
• Any specific subscription plan or product terms presented at the point of purchase.

IMPORTANT: DEPH LABS is not a medical device, does not provide medical advice, and is not a regulated healthcare service. DNA results, epigenetic scores, biological age assessments, supplement recommendations, and AI coaching are for general wellness and informational purposes only. Always consult a qualified healthcare professional about any health concern.

2. Eligibility and Account Registration

2.1 Who Can Use Our Services

You may use our Services if:

• You are at least 18 years old.
• You are accessing the Services for your own personal wellness as an adult man.
• You are legally capable of entering into binding contracts under English law.
• You are accessing the Services from a jurisdiction where their use is lawful.
• You have not previously been suspended or removed from our Services.

Our testing algorithms, epigenetic models, and AI coaching features are calibrated specifically for adult male biology. Results and recommendations are not validated for use by women or minors.

2.2 Creating an Account

When registering, you agree to provide accurate, current, and complete information; keep your account information up to date; keep your password confidential; not share your account; and notify us at support@deph.uk immediately if you suspect unauthorised account use. You are responsible for all activity under your account.

2.3 One Account Per Person

You may hold only one active account. Creating multiple accounts to circumvent restrictions or subscription limits is a breach of these Terms.

3. Not Medical Advice — Critical Disclaimer

READ THIS SECTION CAREFULLY. It describes a fundamental limitation on how you may use our Services.

3.1 All Services — including DNA results, epigenetic scores, biological age assessments, Male Hormonal Age scores, Hair Health scores, supplement recommendations, Engne AI coaching, and any other outputs — are for general informational and wellness purposes only.

3.2 Nothing on our platform constitutes or should be relied upon as:

• Medical advice of any kind.
• A medical diagnosis of any condition, disease, or disorder — including any hormonal disorder, androgenic condition, or cardiovascular condition.
• A clinical assessment of your hormonal health, testosterone levels, or biological age for medical purposes.
• A recommendation for or against any medical treatment, medication, procedure, or prescription.
• A substitute for consultation with a qualified healthcare professional, GP, endocrinologist, or specialist.

3.3 Our Biological Age and Male Hormonal Age scores are wellness metrics derived from epigenetic algorithms. They are not clinical assessments and must not be used to make decisions about hormonal treatment, prescription testosterone therapy, or any other medical intervention.

3.3a Our Hormonal Health epigenetic category — including Male Hormonal Age and androgenic sensitivity scoring — is not a testosterone test and does not diagnose hypogonadism or any endocrine condition. Our Heart Age score is not a diagnosis of heart disease and must not be used to inform decisions about cardiac medication or treatment. Our Hair Health score is not a clinical diagnosis of androgenic alopecia and must not be used to make decisions about medical hair loss treatment or prescription medication. Our epigenetic wellness scores are not equivalent to, and must not be treated as substitutes for, clinical blood tests or assessments by a qualified healthcare professional.

3.4 Our supplement recommendations are based on your genetic profile and are intended to support general wellness. They are not prescriptions, do not replace medical dietary advice, and must not replace prescription medication. Always consult your GP before starting any new supplement, particularly if you are taking prescribed medication.

3.5 Engne AI is a wellness tool. It does not have access to your full medical history and cannot assess your individual clinical circumstances. It is not a substitute for clinical consultation.

3.6 If you are experiencing a medical emergency, call 999 immediately. If you have health concerns, consult your GP.

3.7 DEPH LABS is not regulated by the Medicines and Healthcare products Regulatory Agency (MHRA), the Care Quality Commission (CQC), or any other healthcare regulator.

4. Privacy and Data Protection

The collection, use, and protection of your personal information — including your genetic data, epigenetic data, hormonal health data, and all other health-related data — is governed by our Privacy Policy at www.deph.uk/pages/privacy-policy, incorporated into these Terms by reference. In summary:

• We process genetic and epigenetic data only with your explicit consent.
• We never use your genetic, epigenetic, hormonal, or health data for advertising targeting.
• We never sell your personal data.
• We do not sell or share personal data as defined under CCPA/CPRA.
• Your physical saliva sample is destroyed by our laboratory partner after analysis.
• You can withdraw consent, request deletion of your data, and exercise all rights in the Privacy Policy at any time.
• Full account deletion procedure: www.deph.uk/pages/privacy-policy (Section 11a) or www.deph.uk/pages/engne-app-account-deletion-process.

5. DNA and Epigenetic Test Kits

5.1 What Is Included

Each test kit contains a saliva collection tube, detailed collection instructions, and a pre-paid return envelope (for UK customers; international customers are responsible for return postage). Some kits include access to specific testing categories as set out in the product description at the time of purchase.

5.2 Your Obligations

To ensure accurate results, you must:

• Follow the sample collection instructions carefully, including not eating, drinking, or smoking for 30 minutes before collection.
• Provide a sufficient saliva sample as instructed.
• Return the sample within the timeframe specified in the instructions.
• Ensure the sample is not contaminated.

We cannot be responsible for inaccurate or invalid results caused by failure to follow sample collection instructions correctly.

5.3 Sample Processing and Turnaround

DNA results typically take 3-4 weeks from receipt of your sample at the laboratory. Epigenetic results may take up to 8 weeks due to the complexity of the analysis. We will notify you by email when your results are available. These are estimated turnaround times and may vary due to laboratory capacity.

5.4 Sample Submissions — No Return

Once you have submitted your saliva sample to the laboratory, it cannot be returned to you. Your physical sample will be destroyed by the laboratory after analysis. You may request a replacement kit free of charge if your sample is lost in transit — contact support@deph.uk.

5.5 Invalid Samples

If your sample is insufficient or invalid for analysis, we will notify you and arrange a replacement kit free of charge. We cannot guarantee results for samples that do not meet laboratory quality standards.

5.6 Re-Test Kits

Re-Test Kits allow you to submit a further saliva sample to track changes in your epigenetic profile and biological age over time. Re-Test results are compared against your original baseline within your account. Re-Test turnaround times are the same as standard epigenetic testing.

5.7 Accuracy of Results

We use accredited laboratory partners and validated genetic and epigenetic analysis methodologies. However, no genetic or epigenetic test is infallible. Results are based on current scientific understanding, which continues to evolve. We make no warranty that results will be accurate in all circumstances, and results must not be relied upon for clinical decision-making.

6. Supplements

6.1 Our Supplement Range

Our supplement range includes performance and longevity formulations designed for men: Performance, Longevity, Hair Health, Hormonal Support, and other formulations. Each formulation is developed from our genetic and epigenetic research and uses clinically studied ingredients.

6.2 Important Health and Safety Warnings

Always consult your GP before starting any new supplement, particularly if you are taking prescribed medication, have a diagnosed medical condition, or have concerns about hormonal health. Our supplements are not intended to diagnose, treat, cure, or prevent any disease or medical condition.

Specific warnings:

• Hormonal Support supplements: our hormonal formulations are designed to support general male wellness. They are not a testosterone therapy, are not a substitute for clinical hormonal treatment, and have not been clinically validated to alter testosterone levels.
• Hair Health supplements: our hair health formulations support general scalp and follicle wellness. They are not a medical treatment for androgenic alopecia and have not been clinically validated to prevent or reverse hair loss.
• Drug interactions: some ingredients may interact with prescription medications including anticoagulants, antihypertensives, and hormonal medications. Consult your GP if you are taking prescribed medication.
• Allergies: review the full ingredient list before use. If you have known allergies, consult us or your GP.

6.3 Personalised Recommendations

Supplement recommendations generated by our platform are based on your DNA and epigenetic profile. They are for general wellness purposes and do not constitute personalised medical or dietary advice. The same formulation may be recommended to multiple users with similar genetic profiles.

6.4 Quality and Ingredients

Our supplements are manufactured using high-quality, clinically studied ingredients from trusted suppliers in compliance with applicable UK food supplement regulations. For full ingredient lists and allergen information, refer to the product label and product page on our website.

7. Engne AI Health Coach

7.1 What Engne AI Does

Engne AI is an artificial intelligence wellness coach trained specifically on male genetics, epigenetics, and hormonal patterns. It analyses your genetic results, epigenetic scores, performance data, and health goals to deliver personalised wellness guidance, answer questions about your results, and help you understand your supplement protocol.

7.2 What Engne AI Does Not Do

Engne AI is not a clinician. It does not:

• Provide medical diagnoses or clinical assessments.
• Have access to your full medical history, current medications, or other clinical information beyond what you share in the App.
• Replace a GP, endocrinologist, cardiologist, or any other qualified healthcare professional.
• Make decisions about your care — all guidance is informational and for general wellness only.

7.3 Accuracy and Limitations of AI Responses

AI-generated responses can be incorrect, incomplete, or inappropriate for your individual circumstances. You must exercise independent judgement when acting on any AI-generated wellness guidance. We are not liable for any harm arising from your reliance on Engne AI responses for medical, clinical, or safety-critical decisions.

Engne AI is explicitly programmed not to: provide medical diagnoses; recommend or advise against specific prescription medications; advise you to seek or avoid clinical referral on the basis of your epigenetic or genetic scores; or interpret your results in a manner that suggests a clinical condition. If Engne AI's response ever appears to conflict with advice from your healthcare professional, always follow the advice of your healthcare professional.

7.4 AI and Special Category Data

Engne AI processes your genetic and epigenetic data to generate responses. This involves automated processing of special category data. Under Article 22A UK GDPR (as amended by DUAA 2025), you have the right to request human review of any significant AI-generated output. Contact legal@deph.uk.

8. Intellectual Property

8.1 Our Intellectual Property

All intellectual property in the Services — website, App, software, algorithms (including our epigenetic analysis algorithms and male-specific AI models), designs, text, graphics, and branding — is owned by or licensed to DEPH LABS LTD. Nothing in these Terms grants you any ownership rights other than the limited licence in Section 8.2.

8.2 Licence to Use the Services

Subject to compliance with these Terms and payment of applicable fees, we grant you a personal, non-exclusive, non-transferable, revocable, limited licence to access and use the Services for your own personal wellness purposes.

8.3 Your Data

You retain full ownership of your personal health, genetic, and epigenetic data. By using the Services, you grant us a limited licence to process your data solely to provide the Services to you. This licence terminates when you delete your account and request deletion of your data. We do not claim ownership of your personal data. We will never sell it or use it for advertising.

9. Subscriptions, Pricing, and Payment

9.1 Subscription Plans

We offer free and paid subscription tiers, including our Performance Subscription. Features and pricing for each tier are set out on our website. We will give at least 30 days' notice of any material changes to features or pricing.

9.2 Pricing

All prices are displayed inclusive of applicable VAT at the time of purchase. For price increases: we give at least 30 days' written notice; increases apply to renewals only, not the current period; you may cancel before a price increase takes effect.

9.3 Billing and Payment

Subscription fees are billed in advance on a recurring basis. Payment is processed by our third-party payment processor. If a payment fails, we may retry and may suspend access to paid features until payment is received, with notification to you.

Subscription Transparency: Where we offer both subscription and one-time purchase options, neither option is pre-selected by default — you must actively choose your preferred option before adding to cart. The full subscription terms, including renewal period, total cost per period, and how to cancel, are displayed clearly at the point of purchase. We comply with the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 and DMCCA 2024 requirements for subscription contracts.

9.4 Free Trial / Introductory Offer

Where we offer a free trial or introductory offer, your payment method is charged at the end of the trial/offer period unless you cancel before it ends. We will remind you before charging.

Apple App Store / Google Play Store Subscriptions: If you subscribe through the App Store or Google Play Store, all billing, renewals, and cancellations must be managed through your Apple ID or Google account settings at least 24 hours before the end of the current period. DEPH LABS cannot process refunds or cancellations for App Store / Play Store subscriptions.

9.5 DMCCA 2024 Subscription Rules

The Digital Markets, Competition and Consumers Act 2024 introduces enhanced subscription contract rules. These rules are confirmed for Autumn 2026 commencement at the earliest. We are preparing for full compliance and will update these Terms when the date is confirmed. In the meantime, all existing consumer protections apply in full. We have already implemented automatic subscription cancellation upon account deletion ahead of the statutory commencement date — see Section 10.6.

10. Cancellation, Refunds, and Statutory Rights

10.1 Statutory 14-Day Cooling-Off Right

Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, you have a 14-day right to cancel a subscription or digital service contract from the date you entered into it. If you exercise this right, you will receive a full refund of any subscription fee paid.

To cancel within 14 days: email legal@deph.uk with subject "Cancellation Notice" or use the cancellation function in your account settings. We will process your refund within 14 days of receiving your cancellation notice.

Note: The 14-day right applies to subscriptions and digital services. Physical test kit orders: once you have returned your saliva sample to the laboratory, the testing service has commenced and cancellation rights for that service are extinguished. See Section 10.4 for test kit returns.

App Store / Play Store Subscriptions: Your statutory 14-day cancellation rights still apply, but refunds will be processed through Apple / Google according to their respective refund policies.

10.2 Cancelling After the Cooling-Off Period

You may cancel your subscription at any time through account settings or by contacting us. Cancellation takes effect at the end of your current billing period. No refund is given for the remainder of the current billing period, except as set out in Sections 10.3 and 10.4.

10.3 Refunds for Service Failures

Under the Consumer Rights Act 2015, if we fail to provide the Services with reasonable care and skill and fail to remedy that failure within a reasonable time, you may be entitled to a price reduction or full/partial refund. Contact legal@deph.uk.

10.4 Test Kit Returns and Refunds

Physical test kits (unopened): you may return an unopened test kit within 14 days of receipt for a full refund, in accordance with your statutory cancellation rights under the Consumer Contracts Regulations 2013.

Opened test kits / submitted samples: once you have opened the sealed sample collection tube or submitted your saliva sample, the kit cannot be returned and the testing service is considered commenced. No refund is available for commenced testing services, except where we have failed to deliver results within a reasonable time or where results are invalid for reasons within our control.

Supplements (unopened): subject to our returns policy as described on our website. Supplements that have been opened cannot be returned for hygiene reasons, unless faulty or misdescribed.

10.5 Cancellation Due to Our Changes

If we make a material change to the Services or increase prices and you do not accept the change, you may cancel within 30 days of notice of the change. We will provide a pro-rata refund of any prepaid fees for the unused period.

10.6 Account Deletion and Data Erasure

You may delete your Engne account and all associated personal data at any time. Account deletion automatically cancels your active subscription — you do not need to cancel separately. Your subscription access continues until the end of your current billing period and no further charges are made after your deletion request is received.

How to delete your account:

• In-app: Settings > Account > Delete Account.
• Web: www.deph.uk/pages/engne-app-account-deletion-process.
• Email: privacy@deph.uk — subject "Account Deletion Request".
• iOS native flow (iOS 16+): Settings > [Your Name] > Engne > Delete Account.
• Android native flow (Android 12+): Google Play Store > Profile > Manage Apps & Device > Engne > Delete Account.

All personal data, genetic results, epigenetic scores, Engne AI conversation history, and health data are permanently deleted within 30 calendar days of your request. A small category of data is retained for legal compliance only — see Section 10 of our Privacy Policy for full details.

App Store and Play Store subscribers: Cancellation must also be confirmed in your Apple ID or Google account settings. DEPH LABS cannot unilaterally cancel a platform-billed subscription. We will remind you of this in your deletion confirmation email.

For the full account deletion procedure — including what happens to in-progress orders, partial data deletion options, global jurisdiction rights (CCPA, PIPEDA, Quebec Law 25 including destruction certificates and French language availability on request at privacy@deph.uk, Australian Privacy Act including OAIC complaint rights at oaic.gov.au), and deletion timelines — see Section 11a of our Privacy Policy at www.deph.uk/pages/privacy-policy or visit www.deph.uk/pages/engne-app-account-deletion-process.

13. Suspension and Termination

13.1 Termination by You

Your subscription continues until the end of the current billing period unless you are entitled to a refund under Section 10.

13.2 Termination by Us

We may suspend or terminate your access if you materially breach these Terms (with 14 days to remedy if capable of remedy); we reasonably suspect fraud or illegal activity; or we are required to do so by law. If we discontinue the Services entirely, we will give at least 30 days' notice and a pro-rata refund.

13.3 Effect of Termination

On termination, your licence to use the Services ends immediately. We retain your data per our Privacy Policy. Your UK GDPR rights regarding data deletion are unaffected.

14. Changes to These Terms

Where a change is material, we will give you at least 30 days' written notice by email or in-app notification, explain what is changing and why, and give you the option to cancel without penalty. Non-material changes may be made without notice, though we will update the "Last Updated" date. Continued use after the effective date of a change constitutes acceptance.

• DMCCA 2024 enhanced subscription contract rules (renewal reminders, enhanced cancellation rights): expected Autumn 2026 commencement. We will update these Terms when confirmed. Automatic subscription cancellation on account deletion is already implemented.
