Grif Terms of Service

Version 1.3 — effective 6 October 2026. Changes from 1.2: §1 says what works without a subscription in the words of the Subscription Terms — the calculation of your targets, the manual food diary, weight and progress — and that the AI features, the programme and the meal plan require it; §2 says that the AI coach changes some targets on its own, always with a notification and a one-tap undo (Privacy Policy 1.11, §5); §4 drops the free trial scans, which the app no longer offers; §6 gives the app's current paths for export, erasure and account deletion.

Version 1.2 — effective 26 September 2026. Changes from 1.1: §1 lists the optional features added since — the AI coach, lab reports, the medication tracker and cycle tracking; §2 states plainly that everything the Service shows, including the coach's messages, a transcribed lab value and the medication tracker, is information and reference only and never medical, treatment or medication advice; §6 names the separate consents for lab files and coach messages. Nothing else changes.

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;
  • and, each only if you switch it on and accept its own separate consent (Privacy Policy §4): an AI coach that answers questions about your plan and diary; lab reports — transcription of a report you upload, shown next to the reference range your laboratory printed; a medication tracker for a prescription you already have from your doctor (the medicine, the dose days, side effects you note); and cycle tracking.

Without a subscription the app keeps the calculation of your targets, the manual food diary (catalogue search, barcode, water), weight and progress. The AI features — the AI coach, voice input, food recognition from a photo or a text description and lab report reading — and the programme and the meal plan require a paid subscription (section 5 and the Subscription Terms).

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.

Information and reference only. Everything the Service shows you — the targets, the programme, the meal plan, the coach's messages and notes, a transcribed lab value and the reference range beside it, the medication tracker and its reminders — is general information and a reference for your own decisions. It is not a diagnosis, a treatment plan, a prescription or advice about a medicine. The Service never tells you to start, stop or change a medicine or a dose; the medication tracker records what your doctor prescribed and does not judge it; a lab value is shown against the range your laboratory printed and is never interpreted as a diagnosis; where a value is far outside that range, the only message is to contact your doctor. The AI coach is a language model, labelled «AI» wherever it speaks; it can be wrong, it is instructed to send questions of health to a clinician rather than answer them, and it changes some of your targets and reminders on its own only within fixed limits set by our code, always with a notification and a one-tap undo, and never lowers your calorie target without your approval (Privacy Policy §5). Decisions about your health belong to you and your doctor.

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 part of the paid subscription and is metered by a daily cap (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; a lab report file and a message to the AI coach reach the AI providers only under their own separate consents.

You can export your data from Profile → Data and privacy → Export my data, and erase it or delete your account at any time from Profile → Erase my data and Profile → Delete account.

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.
