CLEAR TERMS

Terms of Use

Version 5.0 · Updated October 3, 2026

At a glance, in six lines

1. leve organizes your treatment records and shows estimates. It does not diagnose, prescribe or recommend doses, and it does not replace the people who care for your health. In an emergency, call 911.
2. You must be 18 or older.
3. You buy the subscription in the App Store, and it renews automatically for the same period until you cancel. The free trial of the annual plan, for eligible people, becomes a paid subscription unless you cancel at least 24 hours before it ends.
4. You can cancel anytime in your iPhone Settings, with no fee. In Brazil, you can also withdraw within 7 days and get your money back.
5. Your records are yours. An account is optional, and you can export and delete your data in the app.
6. Estimates can be wrong and are not a promise of results. We are not responsible for health decisions made without professional guidance (section 14).

1. Who provides leve

leve is provided by Carlos Henrique Borges, an individual residing in Brazil who does business as Alvor Labs. In the App Store, the seller of leve is listed as Carlos Henrique Borges. Address: Rua Doutor Guomide, 002. Email for questions, requests and complaints: alvorlabs@icloud.com. In these Terms, "we" and "us" mean this provider.

2. Acceptance and languages

These Terms of Use apply to the leve app, the useleveapp.com.br website and any web demo versions (together, the "Service"). A link to them appears on the subscription screen, before you buy, and in the app settings, under Terms of use. By subscribing to or using the Service, you confirm that you have read and agree to these Terms. If you do not agree, do not use the Service.

The Privacy Policy explains how we handle your personal data. Agreeing to these Terms is not consent to the use of your health data: that use follows the Privacy Policy, and the optional features (cloud backup, AI meal analysis and Apple Health) ask for your permission before they work.

These Terms are available in Portuguese, English and Spanish, with the same content. If a translation raises a doubt, the interpretation more favorable to you applies.

3. What leve does

leve is a personal record-keeping and organization app for adults who are on, or about to start, treatment with GLP-1 class medicines prescribed by a healthcare professional. You can log injections and doses, weight, side effects, meals and protein, water, sleep, exercise and progress photos. The app calculates readings from these records, such as your weight trend and pace, a projected date to reach your goal, side-effect patterns across the dosing cycle and an estimate of the medicine level in your body.

The Service also includes:

a PDF report for your appointments, created on your device and shared only if you want and with whom you choose;
the Copilot, a guided assistant: you pick from preset questions, and the answers are put together on your device from your records, without sending the conversation to any server. It is not a free-form chat or a medical consultation, and the conversation stays on your device until you use Delete conversation;
local injection and check-in reminders, if you allow notifications;
optional features that only work with your permission: cloud backup, AI meal analysis and Apple Health integration.

4. Health limitations and emergencies

Please read this whole section

leve was not designed or registered as a medical device. It is a record-keeping and organization tool with informational estimates, and it is not intended to diagnose, treat, cure or prevent any disease, or to determine doses.
leve does not diagnose, prescribe, select medicines, calculate or recommend doses, or recommend starting, increasing, reducing, skipping or stopping any treatment.
The doses the app offers for you to log come from the product's prescribing information and from what you entered, for reference only. In the Portuguese version, when an injection is late, the app shows a summary of what the Brazilian package insert says; that summary may become outdated and does not replace your prescriber's advice. In English and Spanish, the app only points out the date with no injection logged and asks you to check with your healthcare professional.
The medicine level curve is a general estimate based on average absorption and half-life data. It does not measure your body. Trends, projections, predicted dates, patterns and the suggested protein goal depend on your records and on general formulas, and they can be wrong.
If you have kidney or liver disease, or are pregnant or breastfeeding, the app does not calculate your protein goal and suggests setting it with your doctor. Until you adjust it, the screens use a general starting value that does not take that condition into account.
leve has not been registered, approved or cleared by the U.S. Food and Drug Administration (FDA), Brazil's Anvisa or Mexico's COFEPRIS.
leve does not replace assessment and follow-up by a physician, dietitian, pharmacist or other healthcare professional.
Never change your dose, schedule or treatment based on what the app shows. Talk to your prescriber first.
Reminders depend on your device's permissions and operation and may not go off. Do not rely on them alone.

Emergencies. If you have severe, persistent abdominal pain, vomiting that will not stop, signs of dehydration, trouble breathing, swelling of the face or throat, a racing heartbeat, confusion, fainting or any other serious symptom, get medical care right away. In the United States, call 911; for a mental health crisis, call or text 988; for a possible poisoning or medicine overdose, call Poison Control at 1-800-222-1222. In Mexico, call 911; for emotional support, call Línea de la Vida at 800 911 2000. In Brazil, call 192 (SAMU); for emotional support, CVV answers at 188. In other countries, call your local emergency number. leve is not an emergency service, does not monitor you in real time, and no one is watching your records on the other side.

5. Who can use leve

The Service is only for people 18 or older who can enter into a binding contract. Setup asks for your date of birth and does not accept an age under 18. By entering it, you confirm that it is true. If we learn that someone under 18 is using leve, we will delete the data about that person that we hold and may end their access.

leve is not designed to follow a pregnancy or breastfeeding. If that applies to you, or if you have any contraindication to your medicine, talk to your prescriber before using the app. The notices the app shows based on your answers are not a clinical assessment.

6. Account, device and backup

You can use leve without an account: your records stay on your device. An account is optional and is used for cloud backup. You can sign in with Apple, Google or email (with a 6-digit code), or tap Save to cloud, which creates an account with no email and no password.

Creating or signing in to an account turns on backup of your records, and the notice next to the button says so before you tap. On iPhone, when that notice mentions photos, Save to cloud also includes your photos, encrypted on your device before upload. If you sign in with Apple, Google or email, photos need a separate permission. Under Profile › Settings › Account and backup you can see the status of your copy and pause backup.

On iPhone, backed-up photos have end-to-end encryption: they are encrypted on your device, and we cannot see their content. To open them on another iPhone, you need the key stored in your iCloud Keychain or your recovery code; signing in alone is not enough. Without the key and the code, those photos cannot be recovered, not even by us. Your records go to the cloud without end-to-end encryption, protected by per-account access rules and the provider's encryption. Outside the iPhone app, there is no end-to-end protection.

Keep your recovery code in a safe place and protect your device. An account created with Save to cloud has no email; so that it does not depend on this device alone, link it to your Apple Account with Protect with Apple on the Account and backup screen. Deleting the app does not cancel your subscription and does not delete your cloud copy.

7. Subscription, free trial and renewal

7.1. Plans and price

Using leve requires a subscription, either an annual plan or a monthly plan. Currently, the annual plan includes a free first week for people who are eligible under Apple's rules, generally those who have not used a leve trial before. The price, currency, length of each billing period and length of the trial are shown on the subscription screen and on Apple's purchase confirmation before you pay, and that is the price that applies. Taxes follow what the App Store shows for your country. There is no sign-up fee, minimum purchase or cancellation fee. Offer codes are redeemed in the App Store and follow the conditions shown when you redeem them.

7.2. How billing works

The purchase is made and charged by the App Store, using the payment method of your Apple Account. We do not receive your card details. Currently, leve is sold only through the App Store, for iPhone.
Your subscription renews automatically for the same period (one year or one month) at the then-current price until you cancel.
Each renewal is charged within the 24 hours before the current period ends.
The free trial ends on its own and becomes the paid annual plan. The first charge happens within the 24 hours before the trial ends, unless you cancel at least 24 hours before it ends. If you allow notifications, the app schedules a reminder before that deadline. If you switch plans during the trial, any unused part of the trial may be forfeited under Apple's rules.
If the price goes up, Apple notifies you in advance under its rules and asks for your consent when the law or the store requires it. The new price only applies from the next period, and you can cancel before then.
On another iPhone with the same Apple Account, tap Restore Purchases on the subscription screen to get your access back.

7.3. How to cancel

You can cancel online at any time, with no fee and without contacting us: in your iPhone Settings, tap your name, then Subscriptions; or in the app, go to Profile › Settings › Subscription › Manage in the App Store, which opens the same Apple screen. Cancelling stops future charges, and you keep access until the end of the period you already paid for or the end of the trial. Deleting the app does not cancel your subscription.

7.4. Refunds

Because Apple processes the payment, refunds are requested from Apple at reportaproblem.apple.com and follow Apple's rules. This does not reduce your rights under sections 18 to 20.

8. AI meal analysis

Meal analysis by photo or text is optional and included in the subscription. Before the first analysis, the app asks Use AI to analyze your meals? and tells you which provider receives the data. Today it is Groq, in the United States, through a server of ours on Cloudflare. Only the meal photo or the description you choose is sent; progress photos and backups are not sent to the AI. If we ever change providers, we will first update the Privacy Policy and ask for your permission again in the app. You can revoke permission under AI Privacy on the protein screen, and manual logging remains available.

The result is an estimate: it may get the food, the preparation or the amount wrong. Review and correct the items before saving. Estimates are not nutrition advice.

The feature has technical usage limits, such as a maximum number of analyses per minute, and it may be unavailable for a while, for example because of a provider outage. If this significantly reduces what you paid for, section 13 applies.

9. Your records

The records and photos you create are yours. We do not claim ownership of them and we do not sell them. You grant us only the license needed to run the Service for you: to store, process and display your data in the app and, when you authorize it, to back it up, always for the purposes in the Privacy Policy. We do not use your records or photos to train artificial intelligence models.

To export, use Account and backup › Export or restore file. The file includes your profile, injections, weight, daily log, meals and exercise. It does not include photos or Copilot conversations, and it is not encrypted, so keep it somewhere private. You can save each progress photo with the share button in the photo viewer. For a complete copy, including what is in the cloud, ask us by email (section 21).

To delete, there are two paths. Start over from scratch, in Settings, deletes the records and photos on this device and the cloud copy, if there is one, and signs you out, but the account itself still exists. Delete account and data in the cloud, under Account and backup while you are signed in, deletes the account, the cloud copy and the data on this device. If you cannot access your account, ask us by email. The Privacy Policy explains what each action deletes and what is kept.

10. Acceptable use

When using the Service, you agree not to:

use leve for any unlawful purpose or in a way that violates the rights of others;
try to access areas, accounts or data that are not yours;
reverse engineer, decompile or extract code, or bypass technical limits or subscription controls;
use bots, scraping or automation to extract content or overload the Service;
resell, sublicense or commercially exploit the Service without written permission;
submit illegal, offensive or third-party content to meal analysis;
present leve, or information obtained from it, as medical advice to others.

Nothing in these Terms prevents you from posting honest reviews and opinions about leve.

11. Apple, Apple Health and other services

The iPhone app is also licensed to you under Apple's Licensed Application End User License Agreement (Standard EULA), which applies together with these Terms. These Terms are between you and the provider of leve (section 1), not Apple. Apple is not responsible for leve or its content, maintenance, support or any claims about it. If Apple's Standard EULA and these Terms address the same point differently, the provision more favorable to you applies, to the extent the law allows.

Apple Health integration is optional. With your permission, leve reads from and writes to Health the data types you authorize, and it never uses that data for advertising. You can remove that permission at any time in your iPhone Settings, under Health.

Third-party services used by leve, such as Apple, the AI provider and the cloud provider, have their own terms. The Privacy Policy explains who receives data and why.

12. Intellectual property

The leve name, logo, interface, text, icons, illustrations, screen layout, calculation methods and software are protected by intellectual property rights and belong to the provider of leve. These Terms give you a personal, limited, non-exclusive and non-transferable license to use the app while you have access to the Service and comply with these Terms. Nothing here transfers ownership.

Medicine brand names shown in the app belong to their owners and appear only to identify the treatment you entered. leve has no relationship with, sponsorship from or affiliation with any pharmaceutical company. Apple, iPhone and App Store are trademarks of Apple Inc.

13. Availability and changes to the app

We work to keep the Service available, but it may be down because of maintenance, third-party failures, network problems or unforeseen events. We may change, add or remove features to improve the product. If a change significantly reduces what you paid for, we will tell you in advance on the leve website and, when we have your email address, also by email. You may then cancel and receive a prorated refund for the paid period you did not use.

14. Liability

We work carefully, but we do not guarantee any weight result, or that calculations, projections and estimates will match what happens to you: they depend on the quality and consistency of your records, and every body responds differently.

To the extent the law allows, we are not responsible for harm caused solely by: (i) health decisions made based on the app without professional guidance; (ii) records that are incorrect, incomplete or not made by you; (iii) problems with your internet connection, mobile carrier or device; (iv) loss of data due to device failure, loss, theft, reset or replacement when backup was off, or loss of protected photos when the key and recovery code are not available.

Nothing in these Terms excludes or limits rights or liabilities that the law where you live does not allow to be excluded or limited, including those under the consumer protection laws of your state in the United States, the Brazilian Consumer Defense Code and Mexico's Federal Consumer Protection Law.

15. Ending access

You can stop using leve whenever you want: cancel your subscription (section 7.3) and, if you wish, delete your account and data (section 9). We may suspend or end your access, with notice, for a serious breach of these Terms, fraud or a legal order. If we end your access through no fault of yours, we will refund the prorated amount for the paid period you did not use. After access ends, the retention periods in the Privacy Policy apply.

16. Changes to these Terms

We may update these Terms. The current version is always on this page, with its number and date at the top. Before material changes take effect, we will announce them on this page and, when we have your email address, also by email. A change that reduces your rights does not apply to a period you have already paid for. If you do not agree with a new version, you can cancel before your next renewal, with no fee.

17. Governing law

These Terms are governed by the laws of the Federative Republic of Brazil. This does not take away any right that the law of the country or state where you live guarantees and does not allow you to waive. The specific rules for the United States, Brazil and Mexico are in sections 18 to 20. In other countries, the mandatory consumer rights of the place where you live apply.

18. Users in the United States

What is charged and when. When you subscribe, you authorize Apple to charge the payment method of your Apple Account the price shown before purchase. Annual plan: if you are eligible for the free first week, the first charge happens when the trial ends, unless you cancel at least 24 hours before it ends, and then again every year. Monthly plan: the first charge happens on the day you subscribe, and then again every month.
Until you cancel. Your subscription continues and renews automatically, at the price shown before purchase, until you cancel. Each renewal is charged within the 24 hours before the current period ends. If the price changes, Apple notifies you in advance under its rules and, where required, asks for your consent; you can cancel before the new price applies. There is no minimum purchase and no cancellation fee.
How to cancel online. On your iPhone, open Settings, tap your name, tap Subscriptions, choose leve and cancel. You can also use Profile › Settings › Subscription › Manage in the App Store in the app. Cancelling stops future charges, and you keep access until the end of the period you paid for or the end of the trial.
Refunds. Apple handles refunds under its policies at reportaproblem.apple.com. Nothing in these Terms limits any cancellation or refund rights you have under the laws of your state, including automatic renewal laws such as California's.
Honest reviews. Nothing in these Terms restricts your right to post honest reviews of leve. We will not penalize you for an honest review or claim any rights over it.
Governing law and courts. These Terms are governed by the laws of Brazil, but nothing in them limits any right you have under the mandatory consumer protection laws of your state of residence. You may bring a claim in the small claims court of the county where you live, if it qualifies, or in the courts of your state of residence. These Terms do not require arbitration.
Emergencies. leve is not an emergency service. In an emergency, call 911. For a mental health crisis, call or text 988 (Suicide & Crisis Lifeline). For a possible poisoning or medicine overdose, call Poison Control at 1-800-222-1222.

19. Users in Brazil

Your rights. The Brazilian Consumer Defense Code (Law No. 8,078/1990), the Brazilian Civil Rights Framework for the Internet (Marco Civil da Internet, Law No. 12,965/2014) and the Brazilian General Data Protection Law (LGPD, Law No. 13,709/2018) apply. How we use your personal data is described in the Privacy Policy.
7-day withdrawal. You can withdraw from your subscription within 7 (seven) calendar days of purchase and, on a plan with a free trial, also within 7 days of the first charge, with a full refund, adjusted for inflation (Consumer Defense Code, article 49). The fastest way is Apple's refund process at reportaproblem.apple.com, the same tool used for the purchase: sign in with your Apple Account, choose to request a refund and select the leve subscription. You can also write to alvorlabs@icloud.com with the subject Withdrawal. We will confirm receipt and, if Apple denies or does not issue the refund, we will refund you directly, at no cost to you. Afterwards, check in your iPhone Settings that the subscription shows as cancelled, so you are not charged again.
Complaints and courts. You can contact us first (section 21) or the consumer protection agency (Procon) in your state. You may bring any dispute before the courts of your place of residence (Consumer Defense Code, article 101, I).

20. Users in Mexico

Your rights. Mexico's Federal Consumer Protection Law (Ley Federal de Protección al Consumidor) applies, and its rights cannot be waived. Nothing in these Terms means that you waive that protection or submit to foreign courts.
Price. The price is shown in Mexican pesos (MXN) on the subscription screen and on Apple's purchase confirmation, before you pay, with taxes as Apple shows them. That is the total charged; we do not add any amount.
Renewal and cancellation. Your subscription renews automatically until you cancel. You can cancel at any time, immediately and without penalty, using the steps in section 7.3. During the free trial, if you cancel at least 24 hours before it ends, you pay nothing.
Refunds. Refunds are requested from Apple at reportaproblem.apple.com, without prejudice to your rights under the Federal Consumer Protection Law, including when the service is not provided or is provided deficiently.
Complaints. Write to alvorlabs@icloud.com. You can also file a complaint with the Federal Consumer Protection Agency (Procuraduría Federal del Consumidor, Profeco), the consumer protection authority in Mexico (gob.mx/profeco), or go to the competent courts of Mexico.
Personal data. The privacy notice in Spanish (aviso de privacidad) is at privacidade.es.html.
Emergencies. Call 911. For emotional support, Línea de la Vida answers free, 24 hours a day, at 800 911 2000.

21. Contact and support

To speed things up, use Withdrawal, Refund, Cancellation or Delete account as the subject, as appropriate. Do not send passwords, recovery codes, card details or body photos.
