Terms and Conditions

Effective: 15 August 2026
Last updated: 11 September 2026

Summary

Glux is a wellness and education application. It is not a medical device. It administers a short questionnaire, calculates your Indian Diabetes Risk Score (“IDRS”), and generates a personalized 90-day habit plan using artificial intelligence.

The Service is available only to individuals aged 18 or over.
Glux does not diagnose any condition. A risk score is neither a test result nor a diagnosis.
Your plan is generated by an AI model and may be inaccurate. Consult a qualified healthcare professional.
Your score is free. All other features are offered on a 2-week free trial, after which the subscription costs ₹499 every 3 months, auto-renewing at the same price until cancelled. Cancellation before the trial ends incurs no charge.
If your subscription ends, your account is locked until you subscribe again. Your data is not deleted, and you may obtain a copy of it or request its deletion by email at any time, free of charge.
You may delete your account in the App at any time. Deletion completes 30 days later, and signing in again within that period cancels it.
Your content remains yours. We process it to operate the Service. We do not use your health information to train AI models.
Enquiries and complaints: contact@goglux.in.

This summary is provided for convenience only and does not form part of the operative provisions. The clauses set out below govern.

1. The operator, and the scope of these Terms

1.1 The Service is operated by Marimuthu, a sole proprietor trading as “Glux”, of Vedha Apartments, 8th Street, Kasturba Nagar, Adyar, Chennai 600020, Tamil Nadu, India (“Glux”, “we”, “us”, “our”).

1.2 These Terms and Conditions (the “Terms”) constitute a binding agreement between you and Glux, and govern your use of:

(a) the Glux mobile application for iOS and Android (the “App”); and
(b) the website at goglux.in, including share pages at goglux.in/s/* (the “Site”),

together, the “Service”.

1.3 By creating an account, completing the questionnaire, or otherwise using the Service, you agree to be bound by these Terms. If you do not agree to these Terms, you must not use the Service.

1.4 Our Privacy Policy sets out what personal data we collect and the purposes for which we process it, and is incorporated into these Terms by reference. In the event of any inconsistency between these Terms and the Privacy Policy in relation to the handling of personal data, the Privacy Policy prevails.

2. Eligibility

2.1 The Service is available only to adults aged 18 years or over. By using the Service, you represent and warrant that you are 18 years of age or older, that you have the legal capacity to enter into these Terms, and that the information you provide is accurate and relates to you.

2.2 We do not knowingly permit accounts to be held by persons under the age of 18. Where we become aware that an account is held by a minor, we will delete that account and the data associated with it.

2.3 The Service is for your personal use only. You must not create an account on behalf of another person, and must not submit another person’s health information to the Service.

3. Description of the Service

3.1 The Service comprises:

(a) the IDRS questionnaire — the Indian Diabetes Risk Score, a published and validated screening questionnaire developed by the Madras Diabetes Research Foundation, which records your age, waist measurement, level of physical activity and family history, and returns a score, a risk band, and a breakdown of the factors contributing to that score;
(b) a personalized 90-day habit plan — AI-generated lifestyle guidance covering activity, nutrition, sleep and habits, derived from your questionnaire responses and profile, and organized into weeks, daily tasks and milestones;
(c) tracking — the recording of your weight, your waist measurement and your daily habits, together with activity and sleep figures read from Apple Health or Google Health Connect where you choose to connect them (clause 13); and
(d) review — re-taking the questionnaire and comparing the result with a previous result.

3.2 An account is required in order to use the Service.

3.3 What the Service is not

The Service is not a diabetes management application, a glucose monitoring application, a medication or insulin application, a calorie counter, a diagnostic tool, or a telemedicine service. It does not connect you to clinicians.

4. No medical advice

Glux is a wellness application and not a medical device. It does not diagnose, treat, cure or prevent any disease or medical condition. All information provided is for educational purposes only. You should always consult a qualified healthcare professional in relation to your health and before making any change to your health routine.

4.1 In particular:

(a) the IDRS is a screening questionnaire and not a test. It involves no blood draw and produces no laboratory or clinical result. A score falling within a higher-risk band does not mean that you have diabetes or prediabetes; it means only that the published scoring table places your responses within that band, and that consultation with a doctor and a confirmatory blood test are advisable;
(b) a score falling within a lower-risk band does not mean that you are in good health, and is not a reason to forgo a medical check-up, disregard symptoms, or discontinue any treatment;
(c) nothing provided through the Service constitutes a prescription, a diagnosis, a treatment plan or individualized medical advice, and no clinician has reviewed your plan; and
(d) you must not disregard or delay obtaining professional medical advice by reason of anything made available to you through the Service.

4.2 Regulatory status

Glux is a wellness and educational application. It is not a medical device. It is not registered with or approved by the Central Drugs Standard Control Organisation (CDSCO), the United States Food and Drug Administration, or any equivalent regulatory authority, and it is not intended to diagnose, treat, cure, monitor, mitigate or prevent any disease or condition, including diabetes or prediabetes.

4.3 Emergencies

The Service must not be used in an emergency. It is not monitored, and no person at Glux reviews communications in real time. If you believe you are experiencing a medical emergency, you should call your local emergency number or attend the nearest hospital immediately. Do not use the App to seek urgent assistance.

5. Intended use and prohibited use

5.1 The Service and its outputs, including your IDRS score, your risk band and your 90-day plan, are intended solely for general wellness and educational purposes, and solely for adults aged 18 or over seeking lifestyle guidance in relation to the risk of Type 2 diabetes.

5.2 You must not:

(a) use the Service or its outputs as a substitute for professional diagnostic testing (including HbA1c or fasting glucose testing) or for clinical evaluation;
(b) rely on the Service to commence, discontinue, dose or adjust any medication or treatment;
(c) use the Service to make decisions concerning, or on behalf of, any other person, including a patient, a family member or a child;
(d) use the Service to manage a diagnosed condition, including diagnosed diabetes, or during pregnancy, otherwise than under the supervision of your doctor; or
(e) use the Service in any other manner inconsistent with the intended purpose stated in clause 5.1 (each of (a) to (e), an “Off-Label Use”).

5.3 You are solely responsible for any Off-Label Use. To the maximum extent permitted by law, we exclude all liability and all warranties in respect of any Off-Label Use.

6. Physical activity, nutrition and your health

6.1 Your 90-day plan may recommend changes to walking, exercise, sleep and diet. General guidance cannot take account of your individual medical circumstances.

6.2 You must consult a qualified healthcare professional before commencing or altering any exercise or dietary regime, and in particular if you are pregnant or breastfeeding, if you have or have had cardiac, renal, hepatic, thyroid or metabolic disease, an eating disorder or a musculoskeletal injury, or if you take any prescription medication, including any diabetes medication or insulin.

6.3 You must stop immediately and seek medical attention if you experience chest pain, breathlessness, dizziness, faintness, unusual fatigue, or any pain during an activity recommended through the Service.

6.4 You undertake any activity recommended through the Service voluntarily and at your own risk, and you are responsible for assessing what is safe and appropriate for you.

7. Your account

7.1 You are responsible for maintaining the confidentiality of your credentials and for all activity occurring under your account. You must notify us at contact@goglux.in immediately if you believe your account has been accessed by another person.

7.2 Your password is stored only as a cryptographic hash, and we are unable to read or recover it; a forgotten password is reset rather than retrieved. You must provide accurate information and keep it current. An inaccurate age, waist measurement or activity response will produce an inaccurate score and an unsuitable plan.

7.3 Deletion of your account. You may delete your account at any time, either in the App under Account → Delete my account or by emailing contact@goglux.in. Deletion does not take effect immediately: we flag the account, sign you out on all devices, and permanently erase your data 30 days thereafter. Signing in again within that 30-day period cancels the deletion and restores the account unaffected. The data erased, and the limited categories of data we are required to retain, are set out in the Privacy Policy.

8. Acceptable use

You must not:

(a) provide false or misleading information in the questionnaire or in your profile;
(b) use the Service for any unlawful purpose or in breach of these Terms;
(c) reverse-engineer, decompile, scrape or copy the Service, or attempt to extract the App’s models, prompts, content, scoring logic or underlying technology;
(d) manipulate, jailbreak or otherwise misuse any AI feature, including in order to elicit medical, diagnostic, dosing or emergency advice, or unlawful or harmful content;
(e) resell, sublicense or commercially exploit the Service or its outputs;
(f) use the Service or its outputs to develop, train or evaluate a competing product or model;
(g) interfere with the operation, integrity or security of the Service, or attempt to access accounts or data belonging to another person; or
(h) circumvent any usage limit, entitlement check or payment mechanism.

9. AI-generated content

9.1 Your 90-day plan is generated by an artificial intelligence model. It is not written or reviewed by a clinician, a dietitian or any other professional.

9.2 AI output may be inaccurate, incomplete, out of date or unsuitable for your circumstances. You are responsible for evaluating it and, where material, for verifying it with a qualified professional before acting on it.

9.3 Any AI feature made available through the Service is instructed to decline to interpret symptoms, to recommend or dose medication, or to state whether you have diabetes, and instead to refer you to a qualified healthcare professional. Those instructions are not guarantees, and all output of an AI feature should be treated as general wellness information.

9.4 Your IDRS score and risk band are not AI-generated in any respect. They are produced by applying the published IDRS scoring table on our server and are returned exactly as the instrument defines them.

9.5 We do not warrant that identical inputs will produce an identical plan or an identical response on any subsequent occasion.

10. Your content, and the licence granted to us

10.1 All material you submit to the Service, including questionnaire responses, profile details, progress logs, notes and any other information you enter (“Your Content”), remains yours.

10.2 You grant us a non-exclusive, worldwide, royalty-free licence to host, store, process, transmit and display Your Content solely in order to:

(a) provide and operate the Service for you, including calculating your score, generating and delivering your plan, recording your progress, and producing your before-and-after comparison;
(b) maintain the security of the Service, diagnose faults and investigate abuse;
(c) produce aggregated and de-identified statistics and product research that cannot be linked back to you; and
(d) comply with applicable law.

10.3 The licence granted in clause 10.2 exists solely to enable us to operate the Service. It terminates when you delete the relevant content or your account — in the case of an account deletion, at the end of the 30-day period described in clause 7.3 — save in respect of backups pending deletion, aggregated de-identified records, and any material we are required by law to retain.

10.4 Restrictions on our use of Your Content

(a) We do not use your health information to train, fine-tune or evaluate any AI model, whether our own or that of any provider. Our AI provider is contractually restricted from using your data to train its models, and we have not granted permission for it to do so.
(b) We do not use your health information for advertising purposes, and we do not sell your personal data.
(c) We do not use your data to develop or adjust the risk score itself. The IDRS scoring table is fixed and published; we apply it and do not modify it.

Retention periods, deletion timelines and your rights are set out in the Privacy Policy.

10.5 Feedback

If you submit suggestions, feature requests or bug reports to us, you grant us an unrestricted, perpetual, irrevocable, royalty-free right to use them without any obligation or compensation to you. You should not submit any material that you regard as confidential.

11. Our intellectual property

11.1 The App, the Site, and our software, designs, brand, name, logo, copy, illustrations, prompts and generated templates are owned by Glux or its licensors and are protected by Indian and international intellectual property law.

11.2 We grant you a limited, personal, non-exclusive, non-transferable and revocable licence to use the Service for your own personal and non-commercial purposes in accordance with these Terms. All rights not expressly granted are reserved.

11.3 We claim no ownership of the IDRS. The Indian Diabetes Risk Score is a published screening instrument developed by the Madras Diabetes Research Foundation. Glux applies its published scoring table and attributes it accordingly.

11.4 You may retain, print and share your own plan and results for personal purposes. You may not redistribute them commercially, or represent them as an endorsement by us of any product, service or person.

12. Pricing, payment, renewal and cancellation

12.1 Features provided free of charge

Your IDRS score, your risk band, the breakdown of the factors contributing to it, and the general next steps accompanying it — including any recommendation to consult a doctor and obtain a confirmatory blood test — are provided free of charge. We do not place the response to a higher-risk result behind a payment.

12.2 Paid features

Feature	Price
Glux membership — the personalized 90-day plan, daily tasks, tracking, reminders and the day-90 retake	Free for 2 weeks, thereafter ₹499 every 3 months, auto-renewing until cancelled

New subscribers are offered a 2-week free trial. No amount is charged during the trial, and cancellation before the trial ends incurs no charge whatsoever. If the trial is not cancelled, it converts automatically, and ₹499 is charged at the commencement of each 3-month period and renews automatically at the same price until cancelled. The free trial is the only discount offered: every renewal is charged at the same ₹499, and that amount is not an introductory rate subject to subsequent increase. The trial is granted by the App Store or Google Play and is subject to their rules; it is available once per store account, and an account that has previously subscribed to Glux may not be offered it. Prices are stated in Indian Rupees and are inclusive of applicable taxes as displayed by the app store at the point of purchase.

12.3 Payment

Purchases are processed by the Apple App Store or Google Play under their respective terms. We do not receive your card, UPI or bank details. Your entitlement is administered through our billing provider, RevenueCat, which receives your application user identifier, the email address and name on your account, and your purchase history, and does not receive your questionnaire responses, score, plan or progress logs.

12.4 Cancellation

You may cancel at any time in your App Store or Google Play account settings. Deleting the App does not cancel a subscription, nor does ceasing to use it; a free trial that is not cancelled becomes a paid subscription. Cancellation during the trial terminates access at the end of the trial, and no amount is charged. After the trial, cancellation takes effect at the end of the 3-month period already paid for; access continues until that date and no further amount is charged. Cancellation must be made at least 24 hours before the trial ends or before a renewal date, as the stores process conversions and renewals in advance.

12.5 Refunds

Refunds in respect of App Store and Google Play purchases are administered by Apple and Google under their respective policies, and should be requested through them. Save where refusal would contravene applicable law, amounts already paid in respect of a current period are non-refundable. Nothing in this clause limits your rights under the Consumer Protection Act, 2019 or any other applicable consumer law.

If you have been charged in error, please email contact@goglux.in and we will assist. Our Refund and Cancellation Policy sets out how to request a refund from each store, the circumstances in which we will support your request, and the time a refund takes.

12.6 Consequences of a subscription ending

Where your subscription ends, whether because you cancelled or because a renewal payment failed, your account is locked upon the expiry of the period paid for. You will not be able to access the App to view your scores, your history, your plan or any record you have logged until you subscribe again.

Your data is not deleted when your account is locked. It remains in your account and becomes accessible again upon renewal, subject to the retention periods set out in the Privacy Policy, including the deletion of accounts that have been inactive for 24 months, of which we will notify you by email in advance.

Payment is never a condition of exercising your data rights. Whether or not you hold an active subscription, and whether or not your account is locked, you may email contact@goglux.in at any time to obtain a copy of your data, to correct it, or to have your account and its data deleted. We will not require you to pay, subscribe or renew in order to do so. A locked account may prevent access to the in-app deletion control; the email route remains available at all times and is not conditional on any payment.

12.7 Changes to pricing

We may change our prices or introduce new paid features. We will notify you before any change affects you, and any change to a recurring price will take effect only in respect of periods commencing after that notice, in accordance with the requirements of the app stores. Continued use of a paid feature after notice constitutes acceptance of the revised price. Promotional offers are made at our discretion, may be withdrawn, and confer no rights beyond their stated terms.

13. Health platform data

13.1 The Service can read activity and sleep data from Apple Health or Google Health Connect. This is opt-in and permission-gated, is off until you enable it, and the Service remains fully functional using manual logging.

13.2 Access is read-only. The Service writes nothing back to either platform.

13.3 Health platform data is read on your device, displayed to you, and discarded. It is not stored on your device, not transmitted to us, and not disclosed to any third party.

13.4 We will not use health platform data for advertising or marketing purposes, sell it, or share it with data brokers.

13.5 You may turn synchronization off in the Service at any time, which stops it reading. Revoking the underlying operating system permission is done in iOS Settings or in Health Connect, and the Service provides a route to both.

13.6 The categories read, and the treatment of that data, are set out in the Privacy Policy at §2.9 and §14.

14. Third-party services

14.1 The Service depends on third parties, including our cloud, authentication, AI, push notification, billing and analytics providers. You must comply with any third-party terms applicable to your use of the Service, including the terms of your app store, the terms of your device platform, and your mobile data agreement.

14.2 The Site links to third-party pages that we do not control, including the App Store and Google Play listings. We are not responsible for third-party content, services or practices.

15. Availability, changes and pre-release features

15.1 We may add, change, suspend or remove features at any time, and we do not warrant that the Service will be uninterrupted, error-free, or available in any particular territory.

15.2 Parts of the Service may be offered on a beta, preview or early-access basis. Such features may be unstable, may change without notice, and may be withdrawn. They are used at your own risk.

15.3 We will give reasonable notice before discontinuing a paid feature you have already purchased, and will address any resulting refund fairly and in accordance with applicable law.

16. Suspension and termination

16.1 We may suspend or terminate your access, with or without notice, if you breach these Terms, if we reasonably suspect fraud or abuse, or if we are required to do so by law. Where it is reasonable to do so, we will inform you of the reason and afford you an opportunity to remedy the breach.

16.2 You may cease using the Service and delete your account at any time. Account deletion is subject to the 30-day reversible period described in clause 7.3 and in the Privacy Policy; signing in again within that period cancels it.

16.3 On termination, your licence to use the Service ends. Clauses which by their nature should survive termination, including clauses 4, 5, 6, 9, 10, 11, 17, 18, 19, 20, 21, 22 and 24, continue in force.

17. Disclaimer of warranties

17.1 To the maximum extent permitted by law, the Service is provided “as is” and “as available”, without warranty of any kind, whether express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement.

17.2 We do not warrant that the Service will be uninterrupted or error-free, that any score, plan or AI output will be accurate, complete or suitable for you, or that use of the Service will produce any particular health outcome.

17.3 Nothing in this clause excludes any warranty or right that cannot be excluded under applicable law, including under the Consumer Protection Act, 2019.

18. Limitation of liability

18.1 To the maximum extent permitted by law, neither Glux nor its team members, contractors or suppliers will be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, data, goodwill or health-related outcome, arising out of or in connection with your use of the Service, whether in contract, tort (including negligence) or otherwise, and whether or not we were advised of the possibility of such loss.

18.2 To the maximum extent permitted by law, our total aggregate liability in respect of all claims relating to the Service is limited to the greater of (a) the amount you paid to us in the 12 months preceding the event giving rise to the claim, and (b) ₹1,000.

18.3 Nothing in these Terms excludes or limits any liability that cannot lawfully be excluded or limited, including liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or any liability arising under applicable consumer protection law.

19. Indemnity

You agree to indemnify and hold Glux harmless against any claim, damage, loss or expense (including reasonable legal fees) arising from your breach of these Terms, your misuse of the Service, any Off-Label Use as defined in clause 5.2, or your violation of any law or of any third-party right.

20. Governing law and disputes

20.1 These Terms are governed by the laws of India. Subject to clause 20.2, the courts at Chennai, Tamil Nadu have exclusive jurisdiction in respect of any dispute arising out of or in connection with these Terms or the Service.

20.2 If you are a consumer, nothing in these Terms removes your right to bring proceedings in the forum to which consumer protection law entitles you, or to complain to a Consumer Commission.

20.3 Before commencing proceedings, please contact us at contact@goglux.in. Most matters can be resolved more quickly by direct correspondence.
