Terms of Use
Last updated: 4 October 2026 · Effective from the same date.
These Terms were originally written in Brazilian Portuguese. In case of conflict between versions, the Portuguese version prevails.
1. Who provides NutriLens
The NutriLens app is provided by João José de Oliveira Leal, an individual trading as MyFlows AI (“we”, “us”, “our”), based in Brazil. The official contact for any matter relating to the app, including these Terms, is [email protected].
The official website is nutrilensapp.myflowsai.com.
2. Accepting these Terms
These Terms of Use form the agreement between you and us regarding the NutriLens app and this website (together, the “Service”). By creating an account, accessing or using the Service, you confirm that you have read, understood and agree to these Terms and to the Privacy Policy.
If you do not agree with any part of them, do not use the Service.
3. What NutriLens is — and is not
NutriLens is a food logging tool. From a photo, a voice recording or a written description, it uses artificial intelligence to estimate the foods present in a meal and their approximate nutritional values, and organises that history alongside targets calculated from the data you provide.
3.1. The nature of the estimates
The values shown are automatically generated statistical approximations, not measurements. They depend on photo quality, angle, lighting, what is visible on the plate, your description and the limitations of the artificial intelligence model used. Foods may be misidentified, portions may be over- or under-estimated, and hidden ingredients such as oils, sugars and sauces may go undetected.
Calorie and macronutrient targets are calculated using population formulas from the weight, height, age, sex, activity level and goal you provide. Population formulas do not capture individual particularities.
3.2. NutriLens is not a health service
NutriLens is not a medical device, does not provide medical, nutritional or any other regulated health service, and does not create a professional-patient relationship. Nothing in the Service constitutes diagnosis, prescription, treatment, dietary prescription or individualised clinical advice.
The Service does not replace assessment by a doctor, dietitian or other qualified professional. Before starting, changing or stopping any eating plan, diet, exercise, medication or health behaviour, consult a professional.
You should not rely on the Service as your sole basis for decisions, and you should seek professional guidance before using it, if you:
- have or have had an eating disorder, or a history of a difficult relationship with food, weight or calorie counting;
- have diabetes, kidney disease, liver disease, cardiovascular disease, coeliac disease, food allergies or intolerances, or any other condition requiring dietary control;
- are pregnant or breastfeeding;
- are under 18;
- take medication whose dosage depends on food intake.
In a health emergency, seek medical care immediately. Do not use the Service for that.
3.3. Chat assistant
The assistant available on paid plans is an automated system based on a language model. Its answers are generated by software, may contain errors and are not professional advice. Everything in section 3.2 applies to it in full.
4. Who may use it
The Service is intended for people aged 18 and over. People aged 13 to 17 may use it only with the consent and supervision of a parent or legal guardian, who is responsible for that use. The Service is not intended for children under 13, and we do not knowingly create accounts for that age group.
By using the Service you confirm that you have the legal capacity to enter into this agreement and that the information you provide is true.
5. Your account
Using the Service requires an account, created with your name and email and a password of your choice, or by signing in with a Google or Apple account. You may also provide a phone number, optionally.
- You are responsible for keeping your password confidential and for all activity on your account.
- You must provide true information and keep it up to date. Incorrect profile data produces incorrect targets.
- Tell us by email as soon as you suspect unauthorised use of your account.
- The account is personal and non-transferable. Do not share credentials or use someone else's account.
- We may ask you to confirm your email. Confirmation is what allows you to recover the account if you forget your password.
6. Daily usage limits and changes to them
Every photo, voice or text analysis calls a third-party artificial intelligence model that charges us per use. For that reason the Service operates with daily limits on the number of analyses, varying by plan. Current limits are shown in the app itself and, indicatively, on the plans page.
6.1. Free plan
The limits, features and the very existence of the free plan are offered as a courtesy, without financial consideration. We may reduce, increase, suspend or discontinue the limits and features of the free plan at any time, at our discretion, with or without prior notice, including immediately, without this giving rise to any right to compensation, credit or continuity of any function.
6.2. Paid plans
For active subscribers we apply a more protective rule: changes that reduce the limits or remove contracted features do not apply to the period already paid for. They take effect only from the following renewal, and we will give at least 30 days' notice by email or in-app notice. If you disagree, you may cancel your subscription before renewal, at no cost, through the store where you subscribed.
Improvements, limit increases and additional features may be applied at any time, including during the current period.
6.3. Technical measures and temporary safeguards
Regardless of plan, we may apply temporary technical restrictions — including reducing limits, throttling requests, refusing analyses or suspending functions — where necessary to:
- contain abusive, automated or fraudulent use, or use that breaches section 9;
- respond to a failure, instability, attack or outage at a third-party supplier;
- contain abnormal cost or volume that threatens the viability of the Service;
- comply with a legal requirement or an order from a competent authority.
Such measures will be proportionate, limited to the time required, and, where they affect subscribers significantly and for a sustained period, will be handled under section 6.2.
6.4. Video bonus
The app may offer free-plan users extra analyses in exchange for voluntarily watching an advertising video. This bonus is a courtesy, has a daily cap, does not accumulate, has no monetary value, cannot be converted into money or credit, and may be changed or ended at any time.
6.5. Counting
Usage is counted daily by our servers, resetting according to the date reported by your device, within a tolerance window. Analyses that fail due to a technical error on our side do not consume your limit; completed analyses where the artificial intelligence identifies no food do consume it, because the processing was actually carried out and charged to us.
7. Paid plans, billing and cancellation
7.1. Who processes payment
NutriLens subscriptions are sold and processed exclusively by the Apple App Store or Google Play, depending on where you downloaded the app. We do not receive, process or store card or payment details. The payment, invoicing and refund relationship is also governed by the relevant store's terms.
7.2. Automatic renewal
Subscriptions renew automatically. The next period is charged according to store rules, usually within the 24 hours before the current period ends, unless cancelled beforehand.
7.3. Cancellation
You may cancel at any time through your App Store or Google Play subscription settings. Uninstalling the app does not cancel the subscription. After cancelling you keep access to paid features until the end of the period already paid for, and you are not charged again.
7.4. Right of withdrawal
Under article 49 of the Brazilian Consumer Protection Code, you may withdraw from the purchase within 7 calendar days of subscribing, with a refund of the amount paid. Because billing is handled by the store, refund requests must be made to Apple or Google; if you have difficulty, write to [email protected] and we will support you as far as we can. Consumers in other countries keep any withdrawal rights their local law grants them.
7.5. Plan and price changes
You may switch plans in the app; the store applies any proportional adjustment under its own rules. Price changes follow store rules and, where they affect renewal of an existing subscription, will be notified in advance, leaving you free to cancel if you disagree.
8. Content you submit
“Content” means the photos, voice recordings, written descriptions, profile data and other information you enter into the Service.
- The Content is yours. We claim no ownership of it.
- You grant us a non-exclusive, limited, royalty-free licence to process, transmit, store and display the Content only to the extent necessary to operate the Service for you — which includes transmitting it to the artificial intelligence provider so the analysis can be performed.
- This licence ends when the Content is deleted, except for transient technical copies and records required by law.
- You confirm that you hold the necessary rights over the Content you submit and that it infringes no third-party right and breaks no law.
- Do not submit photos of other people without their consent, or content containing other people's personal data, identity documents, unlawful or offensive material, or material protected by someone else's copyright.
How this data is handled is set out in the Privacy Policy.
9. Acceptable use
In using the Service, you agree not to:
- circumvent, attempt to circumvent or automate the daily limit counting, the video bonus system or subscription verification;
- access the Service through scripts, bots, usage emulators, modified apps or devices with a tampered operating system, in order to gain an advantage;
- reverse engineer, decompile or attempt to extract source code, keys or credentials from the app or our servers;
- resell, sublicense, rent out or commercially exploit the Service or access to it;
- overload, probe or attack our infrastructure, or attempt unauthorised access to accounts or systems;
- use the Service for unlawful or fraudulent purposes, or to give health advice to others;
- submit offensive, discriminatory or violent content, sexual content involving minors, or content infringing third-party rights.
10. Advertising
The free plan is supported by advertising served through a third-party ad network. We do not control the specific content of each advert shown and we do not endorse advertised products or services. Any relationship arising from a click or a purchase made through an advert is between you and the advertiser. Subscribers on paid plans see no adverts.
11. Service availability
We work to keep the Service available and accurate, but it is provided on the terms described here, without any guarantee of uninterrupted or error-free operation, or that estimates will be exact.
At any time we may: carry out scheduled or emergency maintenance; change, add or discontinue features; change suppliers, including the artificial intelligence provider; and discontinue the Service entirely. If the Service is permanently discontinued, we will give at least 30 days' notice, stop further billing and, where a paid period has not been used, arrange a proportional refund through the means available in the store.
The Service depends on an internet connection, on your device and on third-party services (app stores, cloud providers, artificial intelligence providers). Failures in any of these may affect how it works.
12. Liability
You are responsible for the decisions you make about your diet and your health. As set out in section 3, the Service's estimates are approximations and must not be taken as professional advice.
To the fullest extent permitted by applicable law, we are not liable for: inaccuracy of nutritional estimates; dietary, health, training or other decisions taken on the basis of the Service; data loss caused by device failure, uninstalling the app or account deletion you requested; unavailability caused by third parties; or indirect damages, lost profits or lost opportunity.
Nothing in these Terms excludes or limits liability that the law does not allow to be excluded or limited. In particular, the rights granted to consumers by the Brazilian Consumer Protection Code are fully preserved, including in cases of wilful misconduct, gross negligence, defective service and damage caused by a defect. Where the limitation above is held invalid, the maximum limit permitted by law applies.
13. Intellectual property
The app, the website, the NutriLens name and logo, the visual identity, the texts, the source code and the structure of the Service are owned by or licensed to us, and protected by intellectual property law. These Terms grant you only a personal, limited, revocable, non-exclusive and non-transferable licence to use the app for non-commercial purposes, for as long as your account exists and you comply with these Terms. No other rights are granted.
14. Suspension and termination
We may suspend or terminate access to an account, proportionately to the seriousness of the issue, where there is a breach of these Terms — particularly section 9 —, fraud, use that puts the Service or other users at risk, or a legal requirement.
Except where there is imminent risk, fraud or a legal bar, we will state the reason and give you an opportunity to put things right or to contest the decision through the contact email. Where there is an active subscription and the termination is not attributable to you, the paid and unused period will be refunded proportionally through the means available in the store.
15. Deleting your account
You can delete your account at any time from the app, on the profile screen. Deletion is immediate and irreversible: it erases your registration, your meal history, your weight and water logs, your profile data and all other linked data. There is no way to recover it afterwards.
We keep only a minimal audit record of the deletion request itself, without your email in readable form, so that we can later show that the request existed and when. Details are in the Privacy Policy.
Deleting your account does not cancel an active subscription: cancellation must be done in the App Store or Google Play, as described in section 7.3.
16. Changes to these Terms
We may change these Terms to reflect changes in the Service, in suppliers or in the law. The date of the last update always appears at the top of this page.
Material changes — particularly those that reduce your rights or increase your obligations — will be notified at least 30 days in advance, by email or in-app notice. Changes without material impact, such as wording corrections, take effect on publication.
If you keep using the Service after a change takes effect, you are taken to have accepted the new version. If you disagree, you may close your account and, if you have a subscription, cancel it in the store.
17. Governing law and venue
These Terms are governed by the laws of the Federative Republic of Brazil, including the Consumer Protection Code, the Internet Civil Framework and the General Data Protection Law (LGPD).
We will try to resolve any issue first through the contact email. Failing agreement, the courts of the consumer's domicile are chosen to settle disputes, without prejudice to any other venue the law guarantees. If any provision of these Terms is held invalid, the remainder stays in force.
