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 the European Union. 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”.

Two documents bind you: these Terms and the Data Protection Policy, which forms an integral part of them. Where the two differ on how your information is handled, the Policy 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 in the app at least 30 days before it takes effect, and your agreement is requested again.

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 year of birth and will not open an account below 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 in full and offline: your information stays on your device and never reaches us. An account adds only online backup, syncing between devices, and the web account area.

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 and important notices 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, nothing else, 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.

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 turn on online backup, 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 service is currently provided free of charge, with no advertising and no in-app purchase.

Paid features may be offered in future. They will be clearly identified before any payment, with the price including tax, the term and the renewal conditions. No feature that is free today will become paid without at least 30 days notice in the app, during which you can export your information.

Any payments will be collected by the app store you use (Google Play or the App Store). The store then acts as seller: its billing, renewal and refund policies apply, and you cancel a subscription from your account with them.

If you are a consumer in the European Union, you have a 14-day right of withdrawal on digital content. You lose that right if you ask for immediate performance and expressly acknowledge that loss at the time of purchase, as the law provides. This clause takes effect when a paid offer opens.

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.

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, 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, non-transferable and revocable right of use, 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, in exchange for your data. 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.

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.

Mediation. As a consumer you may use a consumer mediation body free of charge. In France the competent mediator is MEDIATOR · TO BE APPOINTED. 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 Data Protection Policy 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.

Sending feedback. Your message passes through a delivery provider based in the United States before reaching our mailbox.

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.

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 given to you at sign-up, on screen and by email. Activating it in the app, once your account exists, is all it takes for the benefit to apply.

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.

This rank is given to you with your personal code, right after sign-up and by email. 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.

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 and, where applicable, the code of the person who invited you. 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.

It is kept until the end of the programme, then twelve months, long enough to honour the announced benefits. After that it is deleted.

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.
