About NutriRival

Hit your calories. Beat your friends.

NutriRival turns calorie tracking into a game you play with friends. Everyone logs what they eat, and whoever stays on target most often wins. Sticking to a goal is easier when someone is counting on you, and more fun when someone is trying to beat you.

How a battle works

  • Challenge 1 to 5 friends for 3, 7, 14 or 30 days.
  • Everyone plays to their own goal. Each day you eat between 80% and 100% of your own calorie target earns a point. It's fair whatever your size, goal or plan.
  • Comebacks count. A day after everyone missed is worth double, and when everyone hits their zone, it's a team day.
  • Most points wins. On a tie, whoever got furthest toward their target weight takes it.

Everything else you need

  • Fast logging: verified foods from the official ANSES-Ciqual food table, packaged products by barcode, restaurant chains, and AI for everything else.
  • A plan that adapts to you: answer a few questions about your days and NutriRival sets your calories and macros. Every week it checks your weigh-ins and adjusts, with safe limits based on published research.
  • Fasting, steps, water and weight, all in one place. Steps come from Apple Health.
  • Chat with your rivals: messages, voice notes and reactions.
  • In 20 languages.

Your data, your choice

Your rivals see your daily total. Your meals stay private unless you choose to share them, and you decide whether friends see your weight.

Privacy policy

This policy explains what NutriRival collects, why, who can see it, and what you can do about it. NutriRival ("the app") is made by its independent developer ("we", "us").

If anything here is unclear, write to support@nutririval.com.

Who is responsible for your data

The developer of NutriRival is responsible for your personal data (the "controller").
Email: support@nutririval.com

What we collect

Your account

  • Your email address and a password, or your Apple or Google sign-in.
  • Your username.

What you enter in the app

  • Your profile: sex, age, height, weight, target weight, body fat (if you enter it), your goal and your answers about your activity.
  • What you eat, your workouts, water, weigh-ins and fasts.
  • Your calorie and macro goals and your plan's weekly checks.
  • Foods and recipes you create.
  • Your settings: language, region, appearance, notifications and sharing choices.

Steps, if you allow it: the app reads your step count from Apple Health (iPhone) or Health Connect (Android). It only reads steps. It never writes to them and never reads anything else.

Social features

  • Your friends, friend requests and the people you block.
  • Your battles and their results.
  • Chat messages, voice messages and reactions.

Technical data

  • A push notification token, so we can send you notifications.
  • Your time zone, so a battle day ends at your midnight.

We don't collect your location. We don't show ads. We don't sell your data, and we don't use it to track you across other apps or websites.

Your food log, weight and body measurements are health data. We only use them because you enter them to use the app, and only to provide it to you.

Why we use it

  • To run the app: keep your log, work out your goals and your plan, and keep your data in sync across your devices.
  • To run battles and friends: show your rivals what the game needs (below), work out points and results, and deliver messages.
  • To send you emails: confirmation codes and account emails.
  • To send you notifications you can turn off: battle updates, messages, reminders.
  • To keep the service safe: prevent abuse and handle reports.

We process your data to provide the service you signed up for. For your health data, that's with your explicit consent, which you give by entering it, and which you can withdraw at any time by deleting it or your account.

What other people can see

  • Everyone signed in: your username.
  • Your friends and the players of a battle you've joined:
    • your daily calorie total, your goal and your steps;
    • your weight and target weight, unless you turn off Show my weight to friends (Settings → Privacy);
    • during a live battle, your workouts (calories and minutes).
  • Only if you turn on Show my meals to friends (off by default): what you ate each meal, and the names of your workouts. Turning it off removes them.
  • Players in your battles and friends you message: what you send them.
  • Foods you publish: a food you mark Public can be found by everyone. Private foods stay on your phone and in your account.

Someone you've only invited to a battle sees nothing until they join it.

Some of these process data outside the European Economic Area. When they do, the transfer is covered by the European Commission's standard contractual clauses or an adequacy decision.

We may also disclose data when the law requires it.

How long we keep it

  • Your data: for as long as you have an account.
  • Shared meals: removed when you turn sharing off.
  • Battle workouts: removed when the battle ends.
  • Deleting your account deletes your account and everything in it: log, profile, friends, messages, voice messages, reactions and notifications.
    • Battles you played in other people's accounts keep their results, without your data.
    • Foods you made public are deleted with your account.

Your rights

You can:

  • see and correct your data in the app at any time;
  • delete it, or your whole account: Settings → Danger zone → Delete account;
  • get a copy of your data, or object to how we use it, by writing to support@nutririval.com;
  • withdraw your consent at any time, by deleting the data or your account;
  • complain to your data protection authority.

We answer requests within one month.

Security

  • Your data travels encrypted and is stored encrypted at rest.
  • Database rules make sure people only see what this policy says they can see.
  • Passwords are never stored in readable form.

No system is perfectly safe, but we work to keep yours protected.

Children

NutriRival is for people aged 16 and over. We don't knowingly collect data from anyone younger. If you believe a child has given us their data, write to us and we'll delete it.

Changes

If we change this policy, we'll update this page and its date. For important changes, we'll tell you in the app.

Terms of use

These terms apply to the NutriRival app ("the app"), made by its independent developer ("we", "us"). By creating an account or using the app, you agree to them.

1. Who can use NutriRival

  • You must be 16 or older.
  • Don't use the app to restrict your eating if you have, or have had, an eating disorder.
  • If you are pregnant or breastfeeding, or have a medical condition, use it only with your doctor's approval.

2. Not medical advice

NutriRival helps you track food and reach a weight goal. It is not a medical service.

  • Its calorie goals, plans and nutrition values are estimates based on published formulas and research.
  • Food data, from databases, other users and AI, can be wrong.
  • Talk to a doctor or dietitian before a big change to your diet or weight, and stop if you feel unwell.

The app keeps computed goals above safe minimums, but you are responsible for your own health choices.

3. Your account

  • Keep your login safe; you're responsible for what happens in your account.
  • Give a real email address. We use it to confirm your account and for account emails.
  • You can delete your account at any time in Settings.

4. Battles and fair play

  • Battles are a game between friends. There are no prizes or money involved.
  • Points come from what each player logs, and we can't check that a log is true. Play honestly.

5. What you post

You're responsible for what you send or publish: messages, voice messages, reactions, usernames, and foods you make public.

Don't post anything that:

  • is illegal, hateful, harassing, threatening, sexual or violent;
  • impersonates someone, or spams;
  • contains someone else's private information;
  • is false nutrition data posted on purpose.

You keep ownership of what you post. You give us permission to store it and show it to the people it's meant for, and, for public foods, to everyone in the app.

You can block anyone and report a public food. We may remove content and suspend or close accounts that break these rules.

6. Our app

  • The app, its name, logo and design belong to its developer.
  • Don't copy, resell, reverse-engineer or misuse it, or try to access other people's data.
  • Food data comes partly from ANSES-Ciqual (the French food composition table) and Open Food Facts (under the Open Database License), and is credited in the app.

7. Changes and availability

  • We may update, change or stop features, or the app itself.
  • We work to keep it running but can't promise it will always be available or free of errors.
  • If we ever charge for something, we'll tell you clearly first. Nothing you have now will start costing money without your choice.

8. Liability

The app is provided "as is". As far as the law allows, we are not liable for indirect losses, or for decisions you make based on the app's estimates. Nothing in these terms limits rights you have under consumer law that can't be limited.

9. Ending

You can stop using the app and delete your account at any time. We may suspend or close an account that breaks these terms.

10. Changes to these terms

If we change these terms, we'll update this page and its date. For important changes, we'll tell you in the app. Continuing to use the app means you accept the new terms.

11. Law

These terms are governed by the law of Belgium. You also keep the protection of the mandatory consumer laws of the country you live in.

Frequently asked questions

How do I win a battle?

Each day you eat between 80% and 100% of your own calorie goal earns a point. A day after everyone missed is worth double. Whoever has the most points at the end wins. On a tie, whoever got furthest toward their target weight wins. In the app: Battle → How it works.

Why is my goal different from my friend's?

Everyone plays to their own goal, worked out from their own body and plan. That's what makes a battle fair between different people.

What can my friends see?

Your username, your daily calorie total, your goal and your steps. Your weight too, unless you turn it off. Your meals only if you turn on Show my meals to friends. Change both in Settings → Privacy.

I didn't get my confirmation code.

Check your spam folder. On the code screen you can ask for a new one after a minute. Make sure the email address you typed is right.

How do I add a friend?

Battle → Friends → Add, then type their username and tag (like Lea#1234). Your own is in Settings → Account.

My steps don't show.

  • iPhone: Settings → Privacy & Security → Health → NutriRival → turn on Steps.
  • Android: open Health Connect and allow NutriRival to read steps.

Can I use NutriRival on a new phone?

Yes. Sign in with the same account and your data comes back.

How do I delete my account?

Settings → Danger zone → Delete account, then tap it again to confirm. This deletes your account and all its data, and can't be undone.

A food's numbers look wrong.

Verified foods come from the official ANSES-Ciqual table. Products come from Open Food Facts, and some foods were added by other users or AI. If a public food is wrong, report it from the food's page. Otherwise, email us the food's name.

Someone is bothering me.

Block them from their profile: they can't message you or invite you any more. If it's serious, email us.
