Terms of Service — Patients
Zyvai Technologies Private Limited
operating as Nadi Health
Your agreement with Nadi Health as a patient
1. Parties and Acceptance
These Terms of Service (“Terms”) constitute a legally binding agreement between you (“Patient”, “User”) and Zyvai Technologies Private Limited, a company incorporated under the Companies Act 2013 with CIN U62011DL2026PTC465961, registered at 14/12, 2nd Floor, Kalkaji, New Delhi, South Delhi – 110019, Delhi, India, operating under the brand name Nadi Health (“Nadi”, “we”, “our”).
By registering on Sehat (sehatapp.in), the Sehat mobile application, or any other Nadi Health patient-facing platform, you confirm that you have read, understood, and agree to be bound by these Terms and our Privacy Policy (nadihealth.co/privacy). If you do not agree, do not use our services. These Terms are effective from 31 May 2026.
You must be at least 18 years of age to register independently. Minors may be registered by a legal guardian through the Family Vault feature. By registering a minor through the Family Vault, the guardian confirms they are the legal guardian and accepts full contractual liability on behalf of the minor.
2. Nature of the Platform
Second opinions provided through the platform are advisory only and do not constitute a treating relationship between the specialist and the patient. All AI-generated outputs require doctor review and approval before entering any patient record — AI is never auto-approved.
3. Your Health Records and Consent
You retain full ownership of your health records. Doctors may only access your records after you grant explicit, informed, and revocable consent — by scanning a clinic QR code, sharing your consent code, or approving via WhatsApp.
You may revoke consent from any doctor at any time from the Sehat app. Revocation stops future data access but does not delete clinical records (prescriptions, consultation notes) already created during the consented period. You have the right to ask your doctor whether AI was used in your consultation and to request correction of any AI-generated record you believe is inaccurate.
4. ABHA Integration
If you link your ABHA (Ayushman Bharat Health Account) ID to your Sehat account, you consent to Nadi Health sharing health records with ABDM (Ayushman Bharat Digital Mission) in accordance with ABDM’s data sharing policy. ABHA linking is optional and does not affect access to Nadi Health services. Aadhaar numbers are not stored by Nadi Health — Aadhaar verification for ABHA linking is performed through UIDAI’s OTP-based authentication and only a tokenised reference is retained.
5. Family Vault
The Family Vault feature (available on Storage+ and Family Vault subscription tiers) allows you to manage health records for up to 6 family members. As vault owner, you have full access to all members’ records. Cross-member access requires explicit permission from the target member, granted via a one-time WhatsApp approval token valid for 48 hours.
For minor members (under 18 years of age), you as guardian hold consent authority. Upon the minor member reaching 18 years of age, an automatic notification is sent to both the guardian and the member. The member may then create an independent Sehat account. Guardian access to the member’s records is automatically revoked 30 days after the handoff notification unless the member explicitly grants continued access.
6. Appointments and Bookings
6.1 Booking
You may book appointments with doctors who have enabled advance booking. A slot is confirmed only after payment is completed (where applicable). Booking confirmation is sent via WhatsApp.
6.2 Payment Modes
| Mode | Description | Refund Basis |
|---|---|---|
| Free | No payment required. | N/A |
| Token Amount | Small amount collected to reduce ghost bookings. Adjusted against consultation fee. | Doctor’s discretion on no-show |
| Full Fee | Full consultation fee collected at booking. | Doctor’s refund policy applies |
6.3 Check-In
You may check in by scanning the clinic QR code in the Sehat app, or through manual check-in by the clinic assistant. Walk-in patients without a prior booking will be inserted into available gaps in the queue.
6.4 Cancellation
You may cancel a booked appointment at any time before the slot time from the Sehat app. For cash payments made at the clinic, refunds are processed directly by the clinic. For digital payments, approved refunds are processed within 5–7 business days via the payment method used at the time of transaction. In the event of a technical failure after payment is collected, Nadi will automatically issue a full refund within 5–7 business days.
6.5 No-Show — Patient
If you do not attend a booked appointment and are marked as No Show, the clinic’s refund decision for the applicable payment mode is final and recorded in the system.
6.6 No-Show or Cancellation — Doctor
If a doctor cancels or does not honour a confirmed paid appointment, you are entitled to a full refund regardless of payment mode. The platform detects doctor no-shows automatically and initiates the refund — typically within about 15 minutes of the missed appointment — with no action required from you. The refund is issued to your original payment method. If, in exceptional cases, an expected automatic refund is not initiated, email hello@nadihealth.co or raise a dispute through the “Report Issue” option in the app (see Section 16).
7. Second Opinions
Second opinion requests require a platform fee of ₹500. A specialist has 48 hours to accept and a further 48 hours to respond. Second opinions are advisory only — always consult your primary doctor before acting on a second opinion. If no specialist responds within the extended window, a full automatic refund is issued. In the event of a technical failure after payment is collected, Nadi will automatically issue a full refund within 5–7 business days. Urgent findings are flagged immediately via WhatsApp to you and, if shared, to your primary doctor.
8. Subscription Tiers
Current subscription pricing is available at nadihealth.co/pricing. Prices are subject to change with 30 days’ notice. On cancellation of a paid subscription, you will retain access until the end of the current billing period. Your health records are not deleted on cancellation — they remain accessible on the Free tier.
| Tier | Features | Price |
|---|---|---|
| Free | Rx from Nadi doctors, lab upload, basic profile | ₹0/month |
| Storage+ | Upload any health document, self-uploads, clinical photos | ₹49/month |
| Family Vault | Everything in Storage+ plus up to 6 family members | ₹99/month |
9. Subscription Billing, Upgrades and Downgrades
9.1 Recurring Billing
Paid subscription tiers (Storage+ and Family Vault) are billed on a recurring monthly basis through Razorpay. By subscribing to a paid tier you authorise Nadi, through Razorpay, to collect the applicable monthly fee at the start of each billing cycle until you cancel or downgrade. Recurring payments are processed as RBI-compliant e-mandates: you will receive a pre-debit notification at least 24 hours before each charge, recurring charges are subject to the prescribed per-transaction cap of ₹15,000, and you may cancel the mandate at any time through the app or your bank or card issuer.
9.2 Upgrades and Proration
When you upgrade from Storage+ to Family Vault part-way through a billing cycle, you pay only for the remaining days of the current cycle, charged at the price difference between the two tiers (₹99 − ₹49 = ₹50 per month, or approximately ₹1.67 per day) and prorated on a daily basis. The exact prorated amount is always shown to you before you confirm the upgrade.
- Where the prorated amount is more than ₹10, it is charged as a one-time payment via Razorpay before the upgrade takes effect. In practice this applies for most of the cycle, with the charge ranging from about ₹12 (around a week left) up to about ₹48 (early in the cycle).
- Where the prorated amount is ₹10 or less — that is, in roughly the last 6 days of the billing cycle — the upgrade is applied immediately at no additional charge for the rest of the cycle.
From your next billing cycle onward, you are billed the full Family Vault subscription fee of ₹99/month.
9.3 Downgrades
A downgrade (for example, Family Vault to Storage+, or any paid tier to Free) takes effect at the end of your current billing cycle. You keep the features of your higher tier until the cycle ends, after which your plan and billing amount change. No partial refund is issued for the unused portion of a higher tier on downgrade. Your health records are never deleted on downgrade, but if you move below a tier that supports stored documents or additional family members, you remain responsible for exporting or reorganising any data that exceeds the limits of your new tier.
10. AI Features
Nadi Health uses AI (including Google Gemini on Google Vertex AI and other AI language models as updated from time to time) for: consultation scribe transcription, prescription OCR, and second opinion structuring. All AI outputs require doctor review and explicit approval before entering any patient record. AI is never auto-approved.
Audio recorded during scribe sessions is automatically and permanently deleted after transcription (maximum 24 hours). Scribe requires your separate explicit consent, distinct from your general record-sharing consent. The Sehat app displays when AI transcription was used on any consultation.
Audio data for scribe transcription and prescription images for OCR are processed by Google Vertex AI (Gemini) on Google’s infrastructure, which may involve processing outside India. By using AI features, you consent to this cross-border transfer for the sole purpose of AI processing. Raw data is deleted after processing.
11. WhatsApp and Messaging Communications
By registering, you consent to receive the following transactional messages from Nadi Health over WhatsApp, SMS, and/or email depending on availability, which are exempt from DND regulations under TRAI guidelines: OTP for login, prescription delivery, appointment confirmation and reminders, queue position updates, refill and care plan notifications, second opinion status updates, family vault permission requests, and urgent finding alerts.
To opt out of non-essential messages, contact hello@nadihealth.co. OTP and security messages cannot be opted out of as they are required for account security.
12. Cookies
Our web portals (sehatapp.in and associated web applications) use essential cookies for authentication and session management. We do not use third-party advertising cookies. You can manage cookie preferences in your browser settings, but disabling essential cookies will prevent you from logging in.
13. Indemnification
You agree to indemnify, defend, and hold harmless Zyvai Technologies Private Limited, its directors, officers, employees, and agents from and against any and all claims, damages, losses, costs, and expenses (including reasonable legal fees) arising from: (a) your use of the platform in violation of these Terms; (b) any clinical decisions made by independently practising doctors on the platform; (c) inaccuracies in information you have provided; or (d) your violation of any applicable law or regulation.
14. Limitation of Liability
Nadi Health is a technology intermediary under the Information Technology Act 2000. To the maximum extent permitted by applicable law, Zyvai Technologies Private Limited shall not be liable for: (a) clinical decisions made by doctors on the platform; (b) accuracy of AI-generated transcription or OCR where doctor review has been completed; (c) service interruptions due to third-party infrastructure (Google Cloud, WhatsApp, payment processors); (d) loss of data due to patient account actions; or (e) any indirect, incidental, consequential, or punitive damages.
15. Force Majeure
Nadi Health shall not be liable for any failure or delay in performance of its obligations arising from causes beyond its reasonable control, including but not limited to: acts of God, natural disasters, pandemic, government orders or regulations, internet outages, third-party infrastructure failures (Google Cloud Platform, WhatsApp, Razorpay), or any other event outside Nadi’s reasonable control.
16. Disputes and Grievance Redressal
You can raise a dispute about an appointment, payment, refund, subscription charge, or platform error in either of two ways: through the “Report Issue” option in the Sehat app or patient web portal, which opens a dispute linked to the relevant record; or by emailing hello@nadihealth.co with your account details and a description of the dispute. For disputes about a specific clinical interaction, we recommend you also contact the clinic or doctor directly, as clinical matters are the responsibility of the treating doctor.
Nadi Health will acknowledge grievances within 48 hours and respond within 30 days as required under the Consumer Protection Act 2019 and DPDPA 2023. Where appropriate, Nadi may resolve a dispute by issuing a refund or a goodwill credit at its discretion. Nadi’s decision is final for disputes involving platform-level errors; clinical disputes remain subject to the treating doctor’s responsibility and to applicable medical and consumer law.
In the event of a personal data breach, Nadi Health will notify the Data Protection Board of India without delay (with detailed particulars within 72 hours of becoming aware) and will notify affected users without delay, in accordance with the DPDPA 2023 and its rules. Further detail is set out in our Privacy Policy.
