Terms of Use

Last updated: September 21, 2026

The short version. This summary is for convenience. The full Terms below are what apply.

The daily readiness reading, the widgets, the weekly score, the activity calendar and your records are free. Written reports need a Premium subscription, billed by Apple.
VitalBrief is a wellness app. It is not a medical device, and nothing in it is medical advice.
You must be at least 16 to use VitalBrief, and you need a parent's or guardian's permission if you are under 18.
Your data is stored on your device. The App sends health data off the device only when you ask for a written report and have agreed to it in the App.
You keep the rights that the consumer and privacy laws of your country give you.

1. Who we are and what these Terms cover

VitalBrief is an iOS app provided by its developer, the individual named as the seller on VitalBrief's App Store page ("we," "us" or the "Developer"). These Terms of Use (the "Terms") are an agreement between you and the Developer about your use of the VitalBrief app, its widgets and the services it connects to (together, the "App").

When you download the App from the Apple App Store, Apple's Licensed Application End User License Agreement (the "Apple Standard EULA") governs your license to the App, unless a custom license agreement is configured in App Store Connect for your country or region. These Terms supplement it and cover the services specific to VitalBrief: the free features, the subscription, the written reports, health data processing, support and acceptable use. If these Terms conflict with the Apple Standard EULA about the App license, the Apple Standard EULA controls for that license.

By installing or using the App, you agree to these Terms. If you do not agree, do not use the App. Our Privacy Policy explains how personal data is handled and forms part of these Terms.

2. What the App does

The App reads the Apple Health data you choose to share and turns it into readings about your recent patterns.

Free features: the daily readiness reading and its detail view, the widgets, the weekly score and its commentary, the activity calendar with workout notes, and personal records. The App calculates these on your device without any AI service, and they send no health data off the device.
Premium features: the written reports, meaning the 12-month panorama (also called the welcome report) and the weekly and monthly reports, together with their PDF export. A written report is created only when you ask for one, after you have agreed in the App to send the data it needs to an external AI service (see Section 6).

The App evolves, and features may be added, changed or removed in new versions. We will not reduce the Premium features during a subscription period you have already paid for, except as described in Section 5.

3. Wellness information, not medical advice

VitalBrief is a wellness app. It is not a medical device, it is not intended for any medical purpose, and it does not diagnose, treat, cure or prevent any disease. Its readings, scores, reports, trends, patterns and observations are general information about your own recent data, for informational and educational purposes. They are not medical advice and do not replace a qualified healthcare professional.

The readiness reading and its direction (adjust, hold or accelerate) are general suggestions based on data from your devices. They do not assess whether it is safe for you to exercise on a given day. Listen to your body, and stop and seek help if you feel unwell during or after exercise.
Talk to a qualified healthcare professional before starting or changing an exercise program, especially if you are pregnant, have a health limitation or are recovering from an injury, and before any decision about your health, medication or treatment.
Written reports are produced by an AI model and are not reviewed by a person or by a healthcare professional before you see them. They can contain errors, omissions or statements that do not fit your circumstances.
The App depends on data recorded by your devices and by other apps. That data can be missing or inaccurate, and the App works with what Apple Health provides.
The App is not an emergency service. If you think you may have a medical emergency, contact your local emergency services immediately.

4. Age and eligibility

You must be at least 16 years old to use VitalBrief. If you are under 18, or under the age of majority where you live, you may use the App only with the permission of a parent or legal guardian, who agrees to these Terms on your behalf and is responsible for your use of the App, including any purchase.

Written reports send data off your device and rely on your consent (Section 6). Where the law of your country requires a parent's or guardian's consent for the processing of your personal data at your age, you may request written reports only with that consent.

The age rating shown in the App Store describes the App's content under Apple's rating system. It is not the minimum age for using the App, which is set by this Section. VitalBrief is not directed to anyone under 16.

5. Premium subscription, free trial, billing and cancellation

VitalBrief is free to download, and the free features do not require a subscription. Written reports require VitalBrief Premium, an auto-renewing subscription sold through the App Store with monthly and annual options. Prices are shown in your local currency in the App Store and in the App before you buy, and taxes are applied as determined by Apple.

Payment is charged to your Apple Account when you confirm the purchase.
Your subscription renews automatically at the end of each period unless you turn off auto-renewal at least 24 hours before the current period ends. The renewal is charged within the 24 hours before the current period ends.
If a free trial is offered and you are eligible, as determined by Apple, the paid subscription starts automatically when the trial ends unless you cancel at least 24 hours before then. Any unused portion of a free trial is forfeited when you purchase a subscription.
You manage and cancel your subscription in your Apple Account settings. On iPhone: Settings, your name, Subscriptions. Deleting the App does not cancel your subscription.
When you cancel, Premium stays active until the end of the period you have already paid for, and you are not charged again. The free features keep working, and the written reports you have already created stay on your device, where you can keep reading and exporting them.
If the price of your subscription increases, Apple notifies you in advance and, where required, asks for your agreement before the new price applies.
Your subscription is linked to your Apple Account and can be restored on another device with Restore Purchases. Your reports and other app data are not: they stay on the device where they were created (see Section 7).
Payments, billing and refunds are handled by Apple under its terms, and we cannot issue refunds ourselves. You can request a refund from Apple at reportaproblem.apple.com. This does not limit any right of withdrawal or refund you have under the consumer law of your country. If you believe Apple declined a refund you are entitled to, contact us and we will help where we can.

If we stop offering Premium, we will stop selling and renewing subscriptions before the paid service ends, give advance notice through the App, this website or other available channels where reasonably possible, and either keep providing Premium until the end of each subscription period already paid for or work with Apple on the refunds or other remedies required by Apple's policies or applicable law. The same applies if a change outside our reasonable control, such as a legal requirement or the withdrawal of a service we depend on, forces us to materially reduce Premium during a paid period.

6. Written reports and AI processing

When you ask for a written report, the App calculates a summary of the relevant data on your device and sends it, together with your profile and the notes you have written, over an encrypted connection to our proxy, hosted by Cloudflare, which forwards it to an external AI provider. The provider writes the report, and the App stores it on your device. The App does not add your name, email address, Apple Account or a device identifier to these requests. The Privacy Policy explains exactly what is sent, who receives it and how long it is kept.

The App asks for your explicit consent before it sends any data for a report. Nothing is sent unless you ask for a report, so you can stop at any time by not requesting more. Reports you have already created are not affected.
AI-written text can be wrong, incomplete or phrased in a way that does not fit you. Read it as a starting point for your own reflection, check anything important with a qualified professional, and do not rely on it for decisions about your health.
Report writing depends on external services and an internet connection. A request can occasionally fail or take longer than usual, in which case you can try again.

7. Your data stays on your device

VitalBrief has no accounts and no cloud sync. Your readings, scores, reports, profile, notes and preferences are stored on your device. That protects your privacy, and it also means that:

If you delete the App, or lose or reset your device without a backup that includes the App's data, that data is gone. We cannot recover it, because we do not keep a copy.
Reports do not move between devices on their own. They reach a new device only if you restore it from a backup of the old one. You can also export any report as a PDF.
You are responsible for the security of your device, its passcode and its backups.

8. Your content and your reports

Your profile answers, your "About You" text, your workout notes, the notes you add for a report and any other text you enter (your "Content") remain yours. You give us a limited, non-exclusive, royalty-free permission to process your Content only to provide the App's features, mainly by including it in the requests that produce your written reports. We do not sell your Content, use it for advertising or use it to train AI models.

Do not enter information about another person without their permission, and do not enter passwords, identity numbers or payment details. The App does not need them.

The reports created for you are for your personal use. You may keep, print, export and share them, for example with a coach or a healthcare professional.

9. Acceptable use

You agree not to:

use the App for any unlawful purpose or in violation of any applicable law;
reverse engineer, decompile, disassemble or try to extract the App's source code, except to the extent the law expressly allows;
access the report service (our proxy and the AI services behind it) other than through the App, or interfere with, overload or disrupt it;
try to bypass the subscription, rate limits, security measures or other access controls;
submit health or personal data belonging to another person without their permission;
resell, sublicense or commercially exploit the App or its reports without our written permission;
use the App to make emergency or clinical decisions.

10. Intellectual property

The App, including its name, logo, design, code, text, calculations and prompt templates, belongs to the Developer and is protected by intellectual property laws. Subject to these Terms and the Apple Standard EULA, you receive a personal, limited, non-exclusive, non-transferable and revocable license to use the App for your own non-commercial purposes on Apple devices that you own or control. Your Content and your reports are covered by Section 8. If you send us feedback or suggestions, we may use them freely and without any obligation to you.

11. Third-party services

The App relies on services provided by others: Apple (the App Store, Apple Health, in-app purchases and iOS), Cloudflare (which hosts our proxy) and an external AI provider (which writes the reports). Their own terms and privacy policies also apply to your use of their services. We choose and configure these services as described in the Privacy Policy, but we do not control them.

When you export a report, copy it into another app or use the option to explore a report with another AI assistant, the app or service you choose receives that content under its own terms, and we are not responsible for how it handles it.

12. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE," AND WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT AND ACCURACY.

Without limiting the above, we do not promise that:

the App or the report service will be uninterrupted, secure or free of errors;
readings, scores, reports, trends, patterns or observations will be accurate, complete, timely or suited to your circumstances;
the data the App receives from Apple Health, your devices or other apps is accurate.

Some countries do not allow certain warranties to be excluded. Where that is the case, these exclusions apply only as far as the law allows, and nothing in these Terms affects the rights you have as a consumer that cannot be waived.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE DEVELOPER WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF, OR INABILITY TO USE, THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE SAME EXTENT, THE DEVELOPER'S TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATED TO THE APP WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR VITALBRIEF PREMIUM IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM AND (B) USD 50.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for fraud, gross negligence or wilful misconduct, for death or personal injury caused by negligence, or under the mandatory consumer protection law of your country of residence.

14. Indemnification

To the extent permitted by applicable law, you will indemnify the Developer against claims brought by third parties, and the reasonable costs of those claims, that result from your breach of these Terms, your violation of the law, or data about another person that you submitted without their permission. This Section does not apply where consumer protection law does not allow it.

15. Suspension and termination

You can stop using the App at any time by deleting it. Cancel any subscription separately through Apple (Section 5).

We may suspend or block access to the report service, for example for a specific version of the App or a specific source of requests, when that is needed to protect it from abuse, fraud or security threats, or if you materially breach these Terms. If a suspension that is not caused by your breach affects a subscription you have paid for, Section 5 applies.

Sections 3, 7, 8, 10, 12, 13, 14, 17, 18 and 19 continue to apply after these Terms end.

16. Changes to these Terms

We may update these Terms, for example when the App changes or the law requires it. We will publish the new version on this page with a new "Last updated" date. If a change materially affects your rights, we will tell you in the App or on this page reasonably in advance of the date it takes effect. Changes do not apply retroactively, and they do not reduce what you have already paid for during the current subscription period. If you do not agree with a change, stop using the App and cancel your subscription. If you keep using the App after a change takes effect, the updated Terms apply to you.

17. Apple App Store terms

VitalBrief is distributed through the Apple App Store. The Apple Standard EULA and the Apple Media Services Terms and Conditions apply to your download, your App license and your purchases, including billing, renewal, cancellation and refunds, to the extent they govern those matters.

These Terms are between you and the Developer, not Apple. Apple is not responsible for the App or its content, except as provided in the Apple Standard EULA or required by law.
Apple, not the Developer, processes App Store payments and payment information.
The Developer is responsible for the App's features, content, support and privacy disclosures, except where Apple is responsible under the Apple Standard EULA or applicable law.
Apple has no obligation to provide maintenance or support for the App.
You must comply with the applicable Apple terms when you use the App.

18. Governing law and disputes

These Terms are governed by the laws of Brazil, without regard to conflict-of-law rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

If something goes wrong, please write to us first at the address below. Most problems can be solved quickly that way.

Any dispute will be decided by the competent courts of the State of São Paulo, Brazil. If you are a consumer, you may instead bring proceedings in the courts of the place where you live, and nothing in these Terms deprives you of the protection of the mandatory laws of your country of residence.

19. General

These Terms, the Privacy Policy and the applicable Apple terms are the entire agreement between you and the Developer about VitalBrief's services. If any provision is found unenforceable, the rest remains in effect. If we do not enforce a provision, we have not waived it. We may transfer these Terms to someone who takes over the App, provided your rights under them are not reduced. You may not transfer them without our consent.

20. Contact

VitalBrief is provided by the individual developer named as the seller on its App Store page.
