Legal documents

M4Plan is published by Kevin Di Silvestro, an individual resident in Switzerland, referred to here as “we”. Write to us at m4plan.info@gmail.com with any question about these Terms, the app, or your information.

The backup infrastructure is hosted in London, in the United Kingdom. The m4plan.app website is hosted by Vercel. Details are in the Data Protection Policy.

They cover the M4Plan mobile app, the m4plan.app website and the account area reachable from it. Together these are called “the service”.

The documents that bind you are these Terms, the Data Protection Policy, the AI Usage Policy and the Licences, credits and trademarks document, all published on m4plan.app; the early-tester programme is added for those who take part. The last three exist only in French and English. Where they differ on how your information is handled, the Data Protection Policy prevails; for the rest, the text that protects you best prevails.

The service is offered in French, English and Finnish. The version you accepted is the one that binds you, in the language you read it in. The French version serves as a reference between translations, and can never deprive you of what yours says.

You accept these Terms the first time you open the app, through an explicit action. Without that acceptance the service is not available.

We record which version you accepted and when, so that we know which text binds you and only ask again when something has actually changed.

We may change these Terms, in particular to follow changes in the app or in the law. A substantial change is announced to you before it takes effect, in the app, on m4plan.app or by email, with at least 30 days’ notice when it reduces your rights or increases your obligations. Your agreement is requested again when you open the app that carries the new text.

If you decline a new version, you can stop using the service and delete your account. Your information stays exportable until then. A wording fix or a clarification that does not affect your rights may apply without that notice period.

The service is for people aged 16 or over. Setup asks for your age and will not let you continue below 16; we do not check it otherwise, and by using the service you declare that you are at least that age. If we nevertheless learn that an account belongs to someone younger, we delete it.

An account is optional. Without one, the app works offline, within the limits of the free plan: your information stays on your device and does not reach us, apart from the technical requests described in the Data Protection Policy (version check, updates, food search). An account adds online backup, syncing between devices, the web account area (open with a trial, a subscription or free access in progress) and the AI-assisted nutrition estimate. A subscription, restoring a purchase or redeeming a code requires an account.

A compatible device, connectivity, system updates and any related costs are yours. Some features depend on your device and on your Android or iOS version.

You agree not to use the service where doing so would be unlawful, or in breach of sanctions that apply to you.

You give accurate information when creating the account and keep it current. A working email address is required: password resets, important notices and messages about your account and subscription (welcome, trial end, renewal notice, payment incident, deletion confirmation, inactivity notice) go through it.

One account belongs to one person. You are responsible for keeping your password confidential and for what is done from your account. Tell us promptly if you suspect unauthorised access.

You may sign in with your Google account or, on iPhone, with your Apple account. The provider you choose then passes us your email address and display name and, for Google, the address of your profile photo, which you can replace in your profile, and its own terms apply to that sign-in. Apple lets you hide your real address behind a relay: the app accepts it without treating it differently.

You can delete your account at any time from the app settings or from the website. What deletion entails is set out in Article 15 and in the Data Protection Policy.

M4Plan is a wellbeing and routine log. It helps you decide what you want to do, write it down, keep track of how regularly you do it, and enjoy the streak. It is a personal organisation tool, like a diary or a notebook.

Nothing shown in the app is medical advice, a diagnosis, a treatment, a prescription or personalised guidance. The figures it suggests, including calorie needs, macronutrient splits, loads or training volumes, are general estimates produced by public formulas applied to the values you enter. They take no account of your health, your history or any medication. These figures are approximate and are not a guaranteed result: the app guarantees neither the accuracy of the values shown, in particular calories and macronutrients, nor that you will reach any weight, fitness or performance goal.

Ask a qualified professional before making significant changes to your physical activity or your diet, especially if you are being treated for a condition, take medication, are pregnant, or are returning after an injury or a long break.

Stop any activity at once and seek advice if you feel pain, chest discomfort, unusual breathlessness, dizziness or faintness. No target shown by the app is worth ignoring a signal from your body.

Values imported from your phone or a watch come from consumer sensors and can be substantially off. Nutrition values come from community databases or from an automatic estimate, and can be wrong. Do not base any health decision on them. The food filter likewise sets aside meals whose written ingredients contain the words you entered: it does not read a label and knows nothing of traces, so it does not replace your own checking, especially with a severe allergy.

Calorie counting, weight tracking and progress photos can be harmful for some people, in particular anyone with a current or past eating disorder. These modules are optional and can be switched off in settings; the app remains usable without them. If tracking becomes a source of anxiety, speak to a professional.

You keep ownership of everything you add: notes, goals, workouts, meals, measurements, photos and videos. We claim no rights over it.

If you have an account, online backup is active and you grant us a strictly technical licence: to store, transmit, copy and display that content for the sole purpose of running the service for you and on your devices. The licence is free of charge, non-exclusive, limited to that purpose, and ends when the content or the account is deleted.

We do not publish your content, do not share it with any third party for commercial purposes, do not use it for advertising, and do not use it to train an artificial intelligence model.

You confirm you hold the rights to what you add, in particular where a photo or a video shows another person, and that you can evidence their agreement.

If a third party brings a claim against us because of content you added, in particular the image of someone who did not agree to it, you hold us harmless against the direct consequences of that claim. This applies only to the extent of what you did or failed to do, and of what applicable law allows to be placed on a consumer.

We will never use your content, your photos or your image for promotion, communication or illustration without your prior and specific agreement, separate from your acceptance of these Terms.

Points, badges, streaks, chests and other game elements have no monetary value. They cannot be exchanged, transferred or refunded, and are neither a currency, nor a credit, nor a vested right.

We may change how they are awarded, correct a wrong counter, and remove anything obtained by circumventing the rules.

These mechanics involve no stake, no chance and no winnings: they are not gambling.

Rewards you set for yourself bind only you. We neither provide nor guarantee them.

The app can be used free of charge and without advertising, within limits shown in the app, such as the number of goals tracked or how much weight history is displayed. A paid subscription lifts those limits and opens the features reserved for it. What each plan includes is shown before any purchase. The AI-assisted nutrition estimate is reserved for the trial and the subscription, within a daily and monthly limit of estimates shown in the app (during the trial, on certain days of the week only).

The subscription is offered on a monthly or annual plan. Its price including tax, in your store’s currency, its term and its renewal conditions are shown before any payment. A 14-day free trial is offered with the annual plan, if the store grants it (one trial per store account): unless you cancel before it ends, the paid subscription starts when the trial ends. Cancelling during the trial costs nothing. The monthly plan has no trial: it is charged from the purchase.

Payments are collected by the app store you use (Google Play or the App Store), whose billing, renewal and refund conditions apply to the purchase. The subscription renews automatically for a period of the same length unless you cancel before the renewal date from your account with the store. Uninstalling the app or deleting your M4Plan account does not cancel the subscription. A cancellation takes effect at the end of the paid period, and access stays open until then.

If the store reports a payment problem, full access is kept for the grace period it grants, up to 16 days, while it is resolved. After that, or at the end of the paid period if there is no grace period, access to the subscription features closes: your information remains visible and is not deleted, but you can no longer add to it in those features, and the free features stay open. Access reopens as soon as the payment is recorded.

We may change the price of the subscription. The price of an existing subscription does not change: an increase applies only to new subscriptions, and never to a period already paid for. The price shown before purchase is the one charged at each renewal, apart from changes in taxes and unless you have activated a discount or an offer.

Consistency discount. The consistency of your account is measured on the actions you record in the app, week after week: goals, workouts, logged meals, weigh-ins, progress photos, waist measurements. Only the fact that an action was recorded on a given day counts, never its content nor the value of a weight. It is expressed as a gauge from 0 to 100 and three levels, reached at 40, 65 and 85 and kept until five points below their threshold, shown in the app. On the annual plan, the level you hold opens a discount of about 5, 10 or 15% on the next renewal. You must activate this discount yourself in the app, between the thirtieth and the third day before the renewal, as a store offer: it never applies by itself, it covers one annual period, and its price is the one the store shows. Without activation, the renewal is charged at the normal price. Other benefits, such as free time obtained through a code, a referral or a campaign, and the start or come-back offers made by the store, have their own conditions and expiry date, shown in the app; when free time and a discount are both available, the free time is used first. These benefits have no cash value, cannot be transferred or refunded, and free access is valid only on the store of the device where you activate it.

No feature that is free will become paid without at least 30 days notice in the app, during which you can export your information.

If you are a consumer in the European Union, you may withdraw from the subscription contract within 14 days of its conclusion, without giving a reason. With the free trial of the annual plan, the contract is concluded at the start of the trial: the withdrawal period runs during the trial, which you can stop at no cost. The first payment is taken only at the end of the trial; moving to the paid subscription and each renewal do not open a new period. Without a trial (monthly plan, or trial already used), the period runs from the purchase; if you asked for the service to begin during that period, in the event of withdrawal you owe only an amount proportionate to what has been provided up to the withdrawal. This right is exercised under the conditions of the store that collected the payment; you can also withdraw in writing at m4plan.info@gmail.com, using the model form below or any clear statement. This does not limit your rights if the service does not conform to the contract.

An offer for coaching professionals may be opened. It will have separate terms. A professional who follows the people they coach through the service would be responsible for those people’s information and would have to obtain their agreement; these Terms do not authorise that by themselves.

An M4Plan account is required to subscribe, restore a purchase or redeem a code. The subscription is tied to the store where you take it (Google Play or the App Store): it opens the app on the devices of that store, and a second one is needed for the other. Free access (free time, code) is valid only on the store of the device that activates it. Your account and your information follow you from one store to the other.

Subject to Article 14, we run the service carefully, but without any guarantee of continuous availability or freedom from error. Interruptions can occur for maintenance, updates, incidents, or because of a provider or your own network.

We may add, change, limit or withdraw a feature. Discontinuing a significant feature or the whole service is announced with reasonable notice, and you can export your information before the deadline.

Some features depend on third-party services (Health Connect, Apple Health, Open Food Facts, the AI provider, app stores) which may change, restrict or shut down outside our control.

The app lets you export a complete backup, media included, as a file at any time. Keeping your own backups is your responsibility, particularly if you use the service without an account: in that case a loss, a failure or an uninstall destroys your information with nothing we can do about it.

The app, its code, interface, texts, illustrations and sounds, the M4Plan name and the mascot Momo are protected and either belong to us or are licensed to us.

We grant you a personal, non-exclusive and non-transferable right of use, revocable in the cases provided for in Article 15, limited to private use of the service. No other right is granted.

The service includes content and components that do not come from us, and some elements were produced by artificial intelligence tools. The origin of each, the applicable licence and what it changes for your rights are set out in the Licences, credits and trademarks document, published on this page. It forms part of these Terms.

Conformity. We supply the service as described in these Terms and on the app store listing. If you are a consumer in the European Union, you have the statutory guarantee of conformity for digital content and services, including where the service is supplied without payment. That guarantee remains yours and nothing here restricts it.

Updates. We supply the updates needed to keep the service in conformity, including security fixes, for as long as you may reasonably expect given the nature of the service. If you do not install an update whose existence and consequences we told you about, we are not liable for defects that follow.

If something is defective. You may ask us to bring the service into conformity and, if that fails, is unreasonably delayed or causes you major inconvenience, obtain termination of the contract as the law provides. Write to us first: it is the fastest route.

What we do not warrant. Subject to the above, we do not warrant that the app meets a personal goal you have set, that estimates and imported values are accurate, that you will reach any given shape, weight or performance, or that availability is uninterrupted.

Liability. We are liable for damage caused by our fault, as applicable law provides. We neither exclude nor limit our liability for wilful misconduct, gross negligence, harm to life or bodily integrity, defective products, or the statutory guarantee of conformity. For other damage, and only as far as the law protecting you allows, our liability is limited to direct and foreseeable damage.

Subject to paragraph 5 and to the rights that the law does not allow to be set aside, we are not liable for damage arising from use contrary to these Terms, from a decision you took on the basis of an estimate shown by the app, from data loss caused by a failure of your device or by your lack of backups, or from the act of a third party we are not answerable for.

You are responsible for how you use the service, for the content you add, and for complying with these Terms.

You may stop using the service at any time, for any reason: delete your account from the app or the website, then uninstall the app.

We may suspend or close an account for a serious breach of these Terms, unlawful use, or an attack on the infrastructure. Except in an emergency or where the law requires otherwise, we warn you and let you export your information.

Ending the relationship ends your right of use. Your information is deleted within the periods set out in the Data Protection Policy. Clauses meant to survive, in particular those on intellectual property, liability and governing law, remain in force.

These Terms are governed by Swiss law, excluding its conflict-of-law rules and the Vienna Convention on the International Sale of Goods.

If you are a consumer resident in the European Union, this choice cannot deprive you of the protection given by the mandatory rules of your country of habitual residence. Those rules remain yours.

Before taking any action, write to m4plan.info@gmail.com: we acknowledge receipt and answer within 30 days, looking for an amicable solution. This amicable step neither delays nor conditions your right to take legal action.

Mediation. As a consumer you may use a consumer mediation body free of charge. In Finland the matter can be brought before the Consumer Disputes Board, kuluttajariitalautakunta, with Consumer Advisory Services helping you prepare it. This route takes away none of your judicial remedies.

Courts. If you are a consumer, you may bring the dispute either before the courts of your country of residence or those of the publisher’s domicile, and we may sue you only before the courts of your country of residence. In all other cases the courts of the publisher’s domicile have exclusive jurisdiction.

If a clause is held void or unenforceable, the rest stays in force and that clause is replaced by the valid rule closest to the original intent.

Not enforcing a clause on one occasion is not a waiver of the right to rely on it later.

We may assign this contract as part of a reorganisation or a transfer of the business, provided the transferee is bound by the same commitments, including on data protection. You will be told, and may delete your account.

These Terms and the documents listed in Article 2.2 are the entire agreement between you and us about the service.

Force majeure. Neither party is liable for a failure caused by an event beyond its reasonable control: natural disaster, major failure of a network or an infrastructure provider, decision of a public authority, armed conflict. Performance is suspended for the duration of the impediment; if it lasts more than 60 days, either party may end the contract without compensation.

Reporting an infringement. If you believe an element of the service infringes your rights, whether copyright, trademark or image rights, write to us identifying the element, the right you rely on and your contact details. We review every report and remove what has to be removed.

Reporting a security flaw. If you find one, write to us before any public disclosure. We undertake to respond, to fix it within a reasonable time, and to take no action against good-faith research that neither extracted data, nor degraded the service, nor invaded anyone’s privacy.

The controller is Kevin Di Silvestro, an individual resident in Switzerland, publisher of M4Plan. Contact: m4plan.info@gmail.com.

Because M4Plan is offered to people resident in the European Union, the GDPR applies to this processing under its Article 3, alongside the Swiss Federal Act on Data Protection.

We have not appointed a data protection officer: the size and nature of the activity do not require one. Your requests are handled directly by the publisher, at the address above.

Nutrition estimate. When you describe or photograph a meal, that text or image goes to an artificial intelligence provider in the United States, for as long as it takes to get an estimate. Neither your name, nor your address, nor your account identifier goes with it. The provider undertakes not to use that content to train its models and does not keep it beyond its technical safety periods.

Emails. Your feedback message and the emails the app sends you (address confirmation, welcome, trial and subscription, account deletion, inactivity notice, release announcement, come-back offer) pass through a delivery provider based in the United States. It receives your email address, your first name if you gave it, and the content of the message.

Subscription. If you subscribe, your account’s technical identifier and your purchase history, sent by the store, are processed by our subscription management provider, based in the United States, to validate purchases and keep the subscription state. Even without a subscription, the app may present an anonymous identifier to it, with the IP address, the device model and the app version, to display the plans on offer. No health data, no name and no address is passed to it.

These transfers are covered by the European Commission’s standard contractual clauses, together with each provider’s own safeguards. You may ask us for a copy of those safeguards.

Before each transfer we check the protection the provider actually offers, including any certification under the EU-US data protection framework, and we keep a record of that check. You may ask us for its result.

This policy describes every use of artificial intelligence in the M4Plan app and on m4plan.app. It forms part of the Terms of Use and is read together with the Data Protection Policy, which remains the reference document for your rights over your information.

Where this text and either of the other two diverge, the one that protects you better prevails. We undertake to fix the divergence rather than rely on it.

This document is exhaustive: if a use of artificial intelligence is not in it, it does not exist. A new use requires a new version of this text, announced before it becomes active (Article 10).

Every result produced by a model is labelled as such on the screen that shows it, at the moment it is shown. A meal estimate carries an “AI estimate” marker before you save it, not in a document you were supposed to have read beforehand.

What is sent is stated here, and in article 9.3 of the Terms of Use: you take note of it by accepting the Terms, and the estimate screen does not repeat it for every meal. The send itself never happens without a gesture from you, on the button that requests it.

This duty to inform follows Article 50 of the European AI Act, which requires telling a person they are interacting with an AI system and marking generated content. We apply it without waiting for all of its deadlines to bite.

The call goes through our server, never straight from your phone to the provider. That is what guarantees the request carries neither your network address nor the technical identifiers a direct call would expose.

This transfer to the United States is one of the flows that leave Europe, all described in section 8 of the Data Protection Policy; it is the only one that sends the content of a meal. It is covered by the European Commission’s standard contractual clauses.

Neither the text nor the photos you send for an estimate are used to train, fine-tune or evaluate any model, by us or by the provider.

That is not merely our undertaking: it is a clause of the contract binding us to the provider. It does not keep this content beyond its technical security retention, and does not reuse it for any purpose of its own.

We neither build nor commission any model from our users’ information, for any purpose whatsoever, including internal ones.

A model’s output is shown for you to review. Nothing is saved until you confirm, and every value stays editable before and after saving.

We take no decision producing legal effects or significantly affecting you based solely on automated processing, within the meaning of Article 22 of the General Data Protection Regulation. M4Plan contains no such decision and no profiling.

An estimate is often imprecise. A model reads quantities poorly from a photo, misses what it cannot see in a dish, and confuses similar preparations. Treat the figure shown as a starting point to correct, not as a measurement.

The exercise demonstration videos were produced by a model. They give an idea of the movement, not the right way to do it. Do not use them as an instruction on form: Article 6 of the Terms of Use applies in full.

An allergy, an intolerance or an exclusion diet must never be checked against an estimate produced by a model. Read the product label.

We may limit or suspend access to the estimate feature for an account that breaks these rules, as provided by Article 15 of the Terms of Use. We always prefer a warning first.

The service applies technical limits (image size, text length, an identified account required) which are not negotiable and need not be published in detail.

We declare every media item produced by a model: the badge icons (Recraft V3, through Fal.ai), the celebration sounds (ElevenLabs, through the same platform), the exercise demonstration videos (Google’s Gemini models), the illustration photos of the exercises and movements (mostly Google’s Nano Banana 2 and Nano Banana Pro, through Fal.ai), the illustration photos of the default dishes (FLUX 1.1 [pro] ultra, through Fal.ai) and the settings, objects and three-dimensional versions of Momo in the onboarding screens (Google’s Nano Banana Pro images, animated with their soundtrack by ByteDance’s Seedance 2.5, through Fal.ai). Those photos illustrate a dish, they do not describe it: portion, garnish and setting are indicative, and the quantities that count are the ones in the ingredient list. The Licences, credits and trademarks document gives the detail, and we claim no copyright over those files.

That declaration is verifiable, file by file. The record published at https://m4plan.app/ai-provenance.json names each file concerned, the model that produced it, its size and the fingerprint of its bytes. A file added, changed or replaced without appearing there fails an automated check of the repository, on every release.

The Momo mascot, the logo and the interface come from no image model: they are drawn as vectors in the code. The one exception, declared in article 9.1: the three-dimensional and video versions of Momo in the onboarding screens, produced by a model from that drawing. The texts of the app and the website, including the steps of the default recipes, were drafted with the help of an artificial intelligence assistant, then reviewed and approved by the publisher, who is answerable for them like for anything else published under M4Plan. No text is produced by a model while you use the app.

A new use of artificial intelligence, a change of provider or a change of hosting country leads to a new version of this document, announced in the app before it becomes active. A use that changes the nature of what is sent will be asked of you again, not assumed.

If a result produced by a model strikes you as dangerous, discriminatory or seriously wrong, write to us. We review every report, and a feature that cannot be made safe is withdrawn rather than patched at the edges.

For any question about this document, including exercising your rights over information that may have been transmitted: m4plan.info@gmail.com. We acknowledge receipt and reply within one month.

The early tester programme is a usage study. Its purpose is to build the app together with the people who use it, by observing real use and collecting feedback, before a wider release.

It is open to 90 participants, split into three tiers in order of sign-up (Article 3). Beyond the 90th spot, later sign-ups remain valid for the study, but carry no entitlement to any free benefit, and we say so to the person concerned.

Taking part is free and carries no purchase obligation. It is not employment, not paid work, and not a prize draw.

The programme runs until the date we announce, and failing that until we end it under Article 8.

Anyone aged 16 or over, as required by Article 4 of the Terms of Use, with an Android phone or an iPhone and a valid email address.

One seat per person. Several sign-ups made with different addresses to hold several seats are cancelled, all of them together.

Signing up means accepting these terms, the Terms of Use and the Data Protection Policy. All three are on this page.

The benefit comes down to one number: your sign-up rank, that is your position in the order of arrival of every sign-up to the study, across all forms on the site. It is fixed the day you join the study and never changes after that.

The first ten sign-ups get twelve months free. The next thirty get three months free. The next fifty get one month free. Beyond the 90th spot, the sign-up remains valid for the study, with no free benefit attached.

The stated length starts on the day a paid subscription actually exists. For as long as the app is free for everyone, the clock does not run: your benefit is not spent on a period when nobody pays.

A personal code is sent to you at sign-up, by email, to the address you signed up with. On Android, you activate it in the app (Account, Promo code) once your account exists. On iPhone there is nothing to enter: create your account with the same address, without Apple’s “Hide My Email” option, and the benefit applies by itself.

Your feedback is what we fix and plan from. By sending it, you allow us to use, reproduce and implement it in the app, without time limit and without payment. You remain free to do whatever you like with it elsewhere.

An idea you send may be close to something we had already planned, or to another tester’s suggestion. Feedback therefore creates no right over the feature that follows from it, nor over the app.

The test build is entrusted to you personally: do not redistribute it and do not publish the install links.

The tier you get depends on none of your profile, your answers, or a choice we make: your sign-up rank alone decides it, under the thresholds in Article 3.2.

Your tier (twelve, three or one month) is shown on screen after sign-up and in the email that carries your code; your rank number is given to you on request. It does not change afterwards, whatever your participation in the study turns out to be.

Only an exclusion under Article 6, reserved for clear abuse or long inactivity, can end the benefit going forward. Outside that case, the tier you got stays yours for its whole length.

A participant may be excluded from the programme if they:

Save for serious or unlawful abuse, exclusion is preceded by a warning by email and by seven days to put things right or reply to us.

Exclusion ends the benefit for the future. It does not delete your account, does not touch your data, and does not stop you using the app on ordinary terms.

You can leave the programme whenever you want, with no reason given, with a single message to m4plan.info@gmail.com. Free months already started remain yours.

The benefit is personal and non-transferable. It cannot be sold, lent, or moved to another account.

It has no cash value and can give rise to no payment, refund or compensation of any kind.

It covers access to the app. It does not cover your mobile plan, any hardware, or any third-party service.

The benefit is tied to a single account. If that account is deleted, the benefit ends with it and the code cannot be reused on another account.

We may end the programme, in particular once the study is over. Benefits already granted are honoured: free months under way run to their end, whatever the tier.

If a paid subscription is never introduced, there is nothing to honour: the app stays free, which is better for you than the promised benefit.

These terms may change. Any unfavourable change is announced by email thirty days before it applies. Carrying on after that date means accepting it; refusing means leaving the programme, without losing the months already earned.

A WhatsApp group brings together the testers who want it. It is optional: the whole study can be done without ever setting foot in it.

We never add anyone. You message the number shown, from your own phone. Ticking the box on the site only states an intention, and sends us no phone number.

The group is for feedback about the app. Do not post health information there, yours or anyone else’s: it is the wrong place, and we cannot protect it over there.

You can leave the group at any time, from WhatsApp, without leaving the programme.

Every sign-up gets a share link carrying a code. It tells us who someone came through, and nothing else.

It opens no extra benefit, neither for the person inviting nor for the person arriving. Invited people join the study on the same terms, while seats last.

The link is meant for people you know. Mass posting it, buying it, selling it or sending it to strangers voids the code, with no other consequence for you.

Signing up records: your email address, your first name if given, your phone platform (Android or iPhone), whether you want to join the group, the page language, your share code, where applicable the code of the person who invited you, and the country you sign up from, as our host derives it from the connection (we do not keep your IP address: only a temporary fingerprint, erased within 48 hours, is used to limit abusive requests). Nothing else. No phone number is asked for on the site.

This information is used to reach you about the study, to send you the right install link, and to run the programme. It is not used for advertising or for unrelated marketing, and it is neither sold nor passed to third parties.

The legal basis is your consent, given by ticking the box on the form, and the performance of the programme you take part in. The country rests on our legitimate interest in knowing where sign-ups come from, to decide where to promote the study and in which languages to reply.

It is kept 24 months at most after sign-up, or until you ask to be removed. An address that has unsubscribed is kept reduced to the address, the date of the refusal and a token, so that we do not write to you again.

You can ask for access, correction or deletion of this information at any time by writing to m4plan.info@gmail.com. The rest, in particular the rights you hold under the GDPR, is described in the Data Protection Policy.

The build given to testers is a work in progress. It may contain errors, stop working, or lose data. Finding those is the very point of the study.

It is provided as is, with no warranty of availability or of freedom from defects. The liability limits of the Terms of Use apply, and nothing here excludes liability that the law does not allow to be excluded.

The app is not a medical device and replaces no health professional. The warning in Article 6 of the Terms of Use applies in full during the study.

Governing law and dispute resolution are those of Article 17 of the Terms of Use. Where the two documents contradict each other about the programme itself, this document prevails.

The Ambassador programme invites users to tell their story in a public video. It is optional and free. It is neither a job, nor paid work, nor a prize draw.

The invitation appears in the app. You can decline it (“No thanks”, “Not now”): it changes nothing about how you use M4Plan.

This document completes the Terms of Use and the Data Protection Policy, which also apply. Where they differ, the text that protects you best prevails.

Anyone aged 16 or over, holding an M4Plan account, who is the author of the video and holds the rights to its content: image, voice, music, and the agreement of the people who appear in it (Article 7.4 of the Terms of Use).

You publish an honest video of one to three minutes, on the platform of your choice, and send us its public link from the app.

No script is imposed on you, and we do not ask you to speak well of M4Plan: we ask you to be honest, including about what did not work.

Before sending, you tick the charter box (Article 4). Sending counts as acceptance of this document.

No store reviews, ever: neither on Google Play nor on the App Store.

Disclose the collaboration. Since you receive a benefit in return, your post must say it is linked to a collaboration with M4Plan (for example “#partnership”, or the wording your country’s rules require).

Do not present M4Plan as a medical tool, and promise no health result (Article 6 of the Terms of Use). Do not show health data you would not want made public: a public video is public to everyone.

The content must be lawful, respect copyright and image rights, and harm no one. You remain solely responsible for what you publish.

After the video is checked, you receive the benefits shown in the app before you send: a number of free months and a percentage discount on your next renewal.

These benefits follow the rules of Article 11.6 of the Terms of Use: they have no cash value, cannot be transferred or refunded, free access is valid only on the store of the device where you activate it, and the discount must be activated by you, as a store offer.

They are owed only after checking: sending alone entitles you to nothing.

Each video is checked by hand, within the time announced in the app. The result is shown there.

We may refuse a video that breaks the charter, the law or a third party’s rights, or whose link does not open. A refusal takes nothing away from what you had before.

We open the link only to check it. We do not republish it, broadcast it, or reuse it in promotion, communication or illustration, without your prior, written agreement, separate from this one (Article 7.6 of the Terms of Use).

The video stays yours and stays with the platform where you published it. You can delete it or make it private whenever you like.

Sending records: the link of the video, the date of your agreement to the charter, the decision taken, the review note and the reward code assigned. Nothing else is asked for this programme.

This information is used to check the video and to give you the benefit. It rests on the performance of the programme you take part in, is kept for as long as your account exists and is erased with it. Your rights are described in the Data Protection Policy.

We may change or stop the programme for future submissions, by announcing it in the app. Benefits already given for a checked video remain yours.

The governing law and the settlement of disputes are those of Article 17 of the Terms of Use.
