Sustane

Terms of Service

Last updated 18 October 2026

These terms are an agreement between you and Quantifit Health & Wellness Technologies Pvt. Ltd. ("Sustane", "we", "us") for using the Sustane app and this website (together, the "service"). By creating an account or using the service you agree to them. Please also read our Privacy Policy.

1. Not medical advice

Sustane is a general wellness tool. It does not diagnose, treat, cure or prevent any disease, and it is not a substitute for advice from a doctor, dietitian or other qualified professional.

  • Calorie and macro targets, programs, health scores (cardio, metabolic, recovery), risk indications for conditions such as diabetes or heart disease, and AI suggestions are estimates based on what you enter and what your devices record. They can be wrong.
  • Talk to your doctor before changing your diet or activity, especially if you are pregnant or breastfeeding, have or have had an eating disorder, or live with a condition such as diabetes, heart, kidney or liver disease, or take medication.
  • Never ignore or delay professional medical advice because of something you saw in Sustane. In an emergency, call your local emergency number.

2. Who can use Sustane

You must be at least 18 years old and able to form a binding contract. You agree to give accurate information about yourself, since your targets and scores depend on it.

3. Your account

You sign in with Apple, Google or your phone number. Keep access to that account secure; you are responsible for what happens under your Sustane account. You can delete your account at any time in the app under Profile › Delete account.

4. Sustane Pro

  • Some features need a Sustane Pro subscription. Plans, prices and any free trial are shown in the app before you buy and may differ by country.
  • Pro is bought through the Apple App Store and billed to your Apple ID. Apple's Media Services Terms also apply to the purchase.
  • Subscriptions renew automatically at the same price and length unless you cancel at least 24 hours before the current period ends. Your Apple ID is charged within 24 hours before each renewal.
  • If a plan includes a free trial, you won't be charged until it ends; cancel at least 24 hours before it ends to avoid being charged. Any unused part of a free trial ends when you buy a subscription.
  • Manage or cancel in your iPhone's Settings › your name › Subscriptions. Deleting the app or your Sustane account does not cancel a subscription.
  • Refunds are handled by Apple under its policies; request one at reportaproblem.apple.com. We can't issue refunds for App Store purchases ourselves.
  • We may also give Pro access for free or through a promotion. Such access lasts for the period stated when it's given and can end when that period ends.
  • If we change the price of a plan, Apple will tell you beforehand and, where required, ask you to agree.

5. AI features

Meal photo recognition, the AI chef and other AI features use automated models. Their answers, including food identification, nutrition estimates and recipes, can be inaccurate or incomplete. Check them, and always check ingredients yourself if you have an allergy or intolerance. Daily limits apply to AI features to keep them fair for everyone.

6. Food information

Nutrition data comes from sources including the Indian Food Composition Tables (IFCT 2017), USDA FoodData Central, our own curated dishes and Open Food Facts (available under the Open Database License). Values vary between recipes, brands and servings, so treat them as estimates.

7. Acceptable use

You agree not to:

  • break the law or anyone's rights while using the service;
  • copy, scrape, resell or redistribute the service, its food database, programs or recipes;
  • reverse engineer the app or attempt to get around its security, limits or subscriptions;
  • interfere with the service or use automated means to access it, other than as we allow;
  • upload content that is unlawful, harmful or that you don't have the right to use.

8. Your content

Foods, recipes, photos and other content you add stay yours. You give us permission to store, process and display that content only as needed to run the service for you.

9. Our content

The app, its design, programs, recipes, text, artwork and the Sustane name and logo belong to us or our licensors. We give you a personal, non-transferable, revocable licence to use the app on Apple devices you own or control, as these terms and the App Store rules allow.

10. Changes and availability

We work to keep Sustane available and accurate, but we may change, add or remove features, and the service may sometimes be unavailable. We may update these terms; if a change is significant we'll tell you in the app before it takes effect. Using the service after that means you accept the new terms.

11. Ending your use

You can stop using Sustane and delete your account at any time. We may suspend or close an account that breaks these terms or puts the service or other people at risk, and will tell you why unless the law prevents us.

12. Disclaimers and liability

The service is provided "as is" and "as available". To the extent the law allows, we make no promises about results such as weight change or health outcomes, and we are not liable for indirect or consequential losses, or for harm that comes from relying on the service instead of professional advice. Where we are liable, our total liability is limited to the amount you paid for Sustane Pro in the 12 months before the claim. Nothing in these terms limits rights you have under consumer protection law that can't be limited.

13. Apple

These terms are between you and us, not Apple. Apple is not responsible for the app or its content, has no obligation to provide support or maintenance for it, and is not responsible for any claims relating to it. If the app fails to meet any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app (if any); Apple has no other warranty obligation. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

14. Law and disputes

These terms are governed by the laws of India. Please contact us first so we can try to resolve any problem. If we can't, the courts of India will have jurisdiction, without taking away any right you have to bring a claim where you live.
