Grif Terms of Service

Version 1.1 — effective 17 September 2026. Changes from 1.0: the Service is now provided by 42 TAPS INC, a Delaware corporation (introduction, §14); governing law and disputes (§13); purchases on the website are no longer offered (§5); the relation to Apple's standard EULA is stated without a precedence rule (introduction).

These Terms are an agreement between you and 42 TAPS INC, a Delaware corporation ("Grif", "we") for the use of the Grif mobile app on iOS and Android, its backend services, and the website grif.fit (together, the "Service"). By creating an account, buying a subscription, or using the Service you accept these Terms. If you do not accept them, do not use the Service.

On iOS the software itself is licensed to you under Apple's Licensed Application End User License Agreement (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/). Apple's standard EULA governs the licence to the iOS app; these Terms govern the Service. On Android the software is licensed under these Terms.

1. What the Service is

Grif is a fitness and nutrition programme:

  • an onboarding questionnaire (sex, date of birth, height, weight, activity, goal, experience, optional circumferences, food exclusions) from which the Service computes by formula your body-fat estimate, energy expenditure, and daily calorie, protein, fat and carbohydrate targets;
  • a training programme and a meal plan built around those targets;
  • a diary of weight, steps, workouts and meals, with optional import from and export to Apple Health or Health Connect;
  • optional recognition of a meal or a nutrition label from a photograph, and lookup of packaged products by barcode;
  • reminders and a weekly check-in.

The free part of the Service is the calculation and the preview of your targets. The programme, the meal plan, the diary and photo recognition require a paid subscription (section 5).

2. Not medical advice

Grif is not a medical device and provides no medical advice, diagnosis or treatment. The targets are the output of published formulas (US Navy body-fat method; Katch-McArdle or Mifflin-St Jeor; an activity factor; a goal correction) applied to figures you typed. The Service applies safety floors — it never sets a target below your basal rate or below 1 200 kcal (women) / 1 500 kcal (men), cancels a deficit when your BMI is under 18.5, and shows a "see a doctor" notice at BMI 35 or more, age 60 or more, or a very low body-fat estimate — but these are guard rails, not a substitute for a clinician.

You are responsible for deciding whether the programme is appropriate for you. Consult a physician before starting if you have any medical condition, an injury, an eating disorder or a history of one, if you are pregnant or breastfeeding, or if you take medication that affects appetite, weight or exercise. Stop and seek help if you feel unwell. If counting calories causes you distress, the app's "Help" line in Settings points to support resources; please use them.

3. Eligibility and your account

  • You must be at least 18. Onboarding asks your date of birth and stops for anyone younger; the Service will not store a profile for a person under 18 or over 75, because the formulas are not validated outside that range.
  • One account per person. You register with an email address and a password held by our sign-in service; keep them secret and tell us if you suspect misuse. You are responsible for what happens under your account.
  • You must give true figures. The programme is only as good as the numbers you enter, and a false date of birth breaks the age check that exists to protect minors.
  • We may suspend or close an account that breaks these Terms, abuses the Service or is used for fraud; we will tell you why unless the law forbids it.

4. What you can do, and what you cannot

You may use the Service for your own personal, non-commercial fitness. You may not:

  • use it for anyone under 18, or enter another person's body figures without their consent;
  • resell, sublicense, scrape, copy or redistribute the programme, meal plans, recipes, texts, images or food data, except as the data-source licences in the Third-party notices expressly allow;
  • reverse-engineer or probe the app or the API beyond what applicable law permits, or interfere with rate limits, quotas or the consent checks;
  • upload photographs that are not of food, that show identifiable people, or that are unlawful; the vision step is instructed to describe plates and nothing else, and abuse may be reported to the provider;
  • use the Service to build a competing product with automated means.

Fair-use limits. Photo recognition is metered: a small number of free trial scans, then a daily cap on the paid plan (currently shown in the app as "up to 8 scans a day"). Calls that fail on our side are not charged against the cap. Limits may change; the app always shows the current one.

5. Subscriptions, trials, cancellation, refunds

Full details are in the Subscription Terms, which form part of these Terms. In short:

  • Subscriptions are sold through the App Store and Google Play and are billed to your store account, not by us. Prices, currency and any free trial are shown by the store before you confirm and may differ by country.
  • Subscriptions renew automatically until cancelled in the store's subscription settings. Deleting your Grif account does not cancel a store subscription.
  • Refunds for store purchases are decided by Apple or Google under their rules; we cannot issue them.
  • You may buy before creating an account. The purchase is held on your device and attached to the account you then create or sign in to; it cannot later be moved to a different account.

6. Your content and your data

You keep all rights to the figures, diary entries, photographs and text you put into the Service. You grant us a licence to process them to provide the Service to you, as described in the Privacy Policy, which is part of these Terms. Photographs are sent to the vision providers only under the separate consent described there.

You can export, erase or delete your data at any time from Profile → Data and privacy.

7. Our intellectual property

The app, its design, the programme, the meal plans, the recipes, the texts and the brand "Grif" are ours or our licensors'. Nutrition reference data comes from public sources under their own licences (USDA FoodData Central — public domain; CIQUAL/ANSES — Licence Ouverte; CoFID — Open Government Licence v3; Open Food Facts — Open Database License), listed with the required attributions in the Third-party notices. Store and brand marks shown in the app belong to their owners and imply no endorsement.

8. Availability and changes to the Service

We aim to keep the Service available but do not guarantee it. We may change, add or remove features, and may require you to update the app; a version that is too old is told to update and stops there. We may stop offering the Service with reasonable notice; paid periods already started are honoured or refunded through the store as its rules allow.

9. Disclaimers

To the fullest extent the law allows, the Service is provided "as is". We do not warrant that the targets, programme or photo estimates are accurate for you, that the Service will be uninterrupted or error-free, or that it will achieve any result. Food-photo estimates are estimates: they depend on what is visible, they carry a range, and you should check the grams when it matters. Barcode and label data come from third-party sources and may be wrong or out of date. Nothing here limits rights that consumer law gives you and that cannot be excluded.

10. Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental or consequential loss, or for loss of data, profit or goodwill, arising from the Service; and our total liability for any claim is limited to the amount you paid us for the Service in the twelve months before the claim. Nothing excludes liability for death or personal injury caused by our negligence, for fraud, or for anything the law does not allow to be excluded. Where you are a consumer, your statutory rights apply.

11. Termination

You may stop using the Service and delete your account at any time. We may terminate for breach as in section 3. On termination your licence ends; sections 6, 7, 9, 10 and 13 survive. Records we must keep by law are kept as the Privacy Policy describes.

12. Changes to these Terms

We may update these Terms. We will show the new version in the app and on the website with its effective date; material changes are announced in the app before they take effect. Continuing to use the Service after that date means you accept them; if you do not, delete your account and cancel your subscription in the store.

13. Governing law and disputes

These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-laws rules, and disputes are brought before the state or federal courts located in Delaware. This is without prejudice to the mandatory consumer-protection rules of the country where you live: wherever you live, nothing in this section deprives you of the protection those rules give you as a consumer.

If you live in the EU/EEA or the UK, you keep every right that the mandatory law of your country gives you as a consumer, whatever these Terms say; you may bring a claim before the courts of the place where you live; and you may complain to your local consumer-protection authority or, about your personal data, to your data protection supervisory authority (Privacy Policy §8).

Our email address for complaints is support@grif.fit.
