Terms of Service

Effective date: 30 September 2026

1. Introduction

Welcome to Rou. These Terms of Service (“Terms”) cover your use of the Rou iOS app, the website rouapp.com, and everything that comes with them (together, the “Service”). Rou is run by Eva Wadl (“we”, “us”).

By using the Service you agree to these Terms. If you do not agree, please do not use the Service. How we handle your personal data is explained in our Privacy Policy.

2. The Service is free

Rou is currently free to use, and nothing in it costs money. If we ever offer paid extras, we will tell you the price and terms clearly before you buy anything, and you will never be charged without agreeing to it first.

3. Your account

You can read recipes and scan products without an account. To save lists, sync your scan history or share lists, you need an account. When you create one, you agree that:

  • You are at least 16 years old.
  • The information you give us is accurate, and you will keep it up to date.
  • You are responsible for keeping your sign-in details safe and for what happens under your account.
  • You will tell us straight away at support@rouapp.com if you think someone else is using your account.

We may suspend or close accounts that break these Terms or that we reasonably believe have been compromised.

4. Health and nutrition disclaimer

Rou offers nutrition education and general wellness information. It is not a substitute for professional medical advice, diagnosis or treatment.

  • Eva is a Certified Gut Health Nutritionist, not a medical doctor. Her recipes, notes and guidance reflect nutrition education and her professional experience, not clinical medical advice.
  • Talk to your doctor or another qualified healthcare professional before making significant changes to your diet, especially if you have a health condition, are pregnant or breastfeeding, or take medication.
  • Everyone is different. Rou is meant to support your general wellbeing and is not intended to diagnose, treat, cure or prevent any disease.
  • If you notice symptoms that worry you after eating a recipe or product, stop and speak to a healthcare professional.
  • Recipes list their ingredients, but always check them, and the labels of the products you use, against your own allergies and intolerances.

5. The scanner and the Gut Score

The scanner reads a product's barcode and shows what is in it and how it fits with gut-friendly eating, including a Gut Score and an explanation of what went into it.

  • The Gut Score and everything shown with it are general nutrition information, not medical advice and not a personal diagnosis. They are based on publicly available product data and on Eva's professional opinion of what supports gut health.
  • Product information comes from public databases, mainly Open Food Facts and USDA FoodData Central. It can be incomplete, out of date or simply wrong, and manufacturers change their recipes. We cannot guarantee that it is accurate.
  • Always read the label on the package, especially for allergens. Never rely on Rou alone to decide whether a product is safe for you to eat.
  • “For you” notes based on your dietary needs are a helpful prompt, not a guarantee that a product is free from something.

Product data from Open Food Facts is © Open Food Facts contributors and is made available under the Open Database License (ODbL). Product images from Open Food Facts are licensed under Creative Commons Attribution-ShareAlike (CC BY-SA). Data from USDA FoodData Central is in the public domain. See openfoodfacts.org for more.

6. Shared lists

You can share a list with other people using an invite link. Anyone who has the link can join the list, so share it only with people you want on it. Invite links expire after 30 days, and the list owner can turn a link off at any time.

Everyone on a shared list can see the other members' names and photos and what they add, vote for and write in notes. When you use a shared list, you agree to:

  • Keep notes, list names and your display name and photo friendly and respectful: nothing abusive, hateful, harassing, sexually explicit, or otherwise unlawful.
  • Not post other people's personal information, spam or advertising.
  • Not use invite links to add people to a list who do not want to be on it.

A list owner can remove members, and any member can leave a list at any time. If someone misuses a shared list, tell us at support@rouapp.com. We may remove content or suspend accounts that break these rules.

7. Content and intellectual property

Eva's recipes, notes, articles, photos, videos, text and the Rou name and design are owned by Eva Wadl and protected by copyright and other laws. Product information and images shown by the scanner belong to their respective sources and licences (see section 5).

  • You are welcome to use Rou's content for your own personal, non-commercial cooking.
  • You may not copy, republish or redistribute Rou's recipes or other content outside the Service, or create commercial works from it, without our written permission.

Your content

What you create in Rou, such as your lists, notes, display name and profile photo, stays yours. You give us a limited, non-exclusive licence to store, process and display it only so we can run the Service, including showing it to the members of lists you share. We will not sell your content or make it public.

8. Acceptable use

When using the Service, you agree not to:

  • Scrape, crawl or use automated tools to extract recipes, product data or other content from the Service.
  • Send automated or excessive requests to the scanner or otherwise try to overload, disrupt or get around the limits of the Service.
  • Reverse engineer, decompile or disassemble any part of the Service, except where the law allows it.
  • Try to access other people's accounts or data, or lists you have not been invited to.
  • Use the Service for anything unlawful.

If you break these rules we may suspend or close your account.

9. Deleting your account

You can delete your account at any time in the app: tap your avatar on Today, then You → Delete account. Deletion is immediate and cannot be undone. Shared lists you own that still have other members pass to another member; the rest of your data is deleted as described in our Privacy Policy. If you cannot use the app, email support@rouapp.com.

We may also close accounts that break these Terms. If we stop offering the Service, we will give you reasonable notice where we can.

10. Limitation of liability

The Service is provided “as is” and “as available”. We work hard to keep Rou accurate and running, but we do not promise that it will always be available, error-free, or that recipes, nutrition figures or product information are complete and correct.

To the fullest extent permitted by law, we are not liable for any indirect, incidental, special or consequential loss arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the amount you paid us, if any, in the twelve months before the claim. Nothing in these Terms limits liability that cannot be limited by law, or your statutory rights as a consumer.

11. Changes to these Terms

We may update these Terms as Rou changes. When we make significant changes, we will update the “Effective date” at the top of this page and let you know in the app or by email before they take effect. If you keep using the Service after that, the updated Terms apply. If you do not agree, please stop using the Service and delete your account.

12. Governing law

These Terms are governed by the laws of the country in which Rou is operated, without regard to conflict-of-law rules. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring a claim in your local courts.
