V Core

Terms of Service

Last updated: August 5, 2026 · Legal home · Privacy Policy

These Terms of Service (“Terms”) govern your access to and use of the V Core iOS application and related services (the “Service”), operated by MUHD DESENVOLVIMENTO DE SOFTWARE LTDA, a Brazilian limited company registered under CNPJ 68.395.651/0001-61 (“V Core,” “we,” “us,” or “our”). By using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. The Service

V Core is a personal wellness and fitness companion. It provides tools that may include profile setup, food and nutrition logs, sleep and mood tracking, menstrual-cycle tracking, training and gym logs, medication and supplement records, body metrics, Apple Health connections, calculations, estimates, plans, trends, and general wellness insights. Features may vary by version, device, region, account status, and permission.

2. Not medical advice or a medical device

V Core is not a medical device and does not provide medical advice, diagnosis, treatment, prescriptions, clinical monitoring, or emergency services. It is intended for personal recordkeeping and general wellness and fitness information only.

Information, targets, plans, estimates, and automated outputs may be incomplete, inaccurate, delayed, generated from limited data, or unsuitable for your circumstances. Do not use V Core instead of a qualified healthcare professional or to make an emergency, diagnostic, treatment, medication, pregnancy, or contraceptive decision. If you believe you have a medical emergency, contact local emergency services immediately.

3. Medication and supplement records

Medication, contraceptive, hormone, and supplement features are personal recordkeeping and organization tools only. V Core does not prescribe, recommend, calculate, verify, modify, or monitor doses; screen for contraindications or interactions; determine whether a substance is safe or appropriate; or tell you to start, stop, or change any treatment.

Names, doses, schedules, reminders, adherence entries, and notes are entered or selected by you. A saved entry confirms only what was recorded, not that it is medically correct or safe. Follow instructions from your qualified healthcare professional and the applicable product label. Contact a healthcare professional or pharmacist with medication or interaction questions.

4. Cycle and fertility estimates

Menstrual-cycle, period, ovulation, and fertile-window dates are estimates based on the information available to V Core. Actual timing can vary, especially with irregular cycles, illness, medication, hormonal contraception, pregnancy, postpartum changes, or incomplete data.

Do not use V Core’s estimates as contraception, to confirm or rule out pregnancy, or as the sole basis for trying to conceive, fertility treatment, or a medical decision. Use an appropriate contraceptive method and seek professional advice for reproductive-health questions.

5. Eligibility and accounts

You must be at least 13 and meet any higher minimum age required in your country to use the Service or consent to personal-data processing. If local law permits use only with a parent’s or guardian’s authorization, that person must review and agree to these Terms.

The current version does not create a remote V Core account. If a future version enables remote account creation, you must provide accurate information, protect your credentials, and promptly notify us of suspected unauthorized access. You may not create an account for another person without authorization.

6. License and Apple terms

Subject to these Terms and Apple’s applicable usage rules, V Core grants you a personal, limited, revocable, non-exclusive, non-transferable license to use the application on Apple-branded devices you own or control for lawful, non-commercial purposes. The application is licensed, not sold.

The application is distributed under Apple’s Standard Licensed Application End User License Agreement (“Apple Standard EULA”). These Terms govern the V Core Service and supplement the Apple Standard EULA. Apple is not responsible for operating, maintaining, or supporting V Core except as Apple’s terms expressly provide.

7. Acceptable use

You may not:

• use the Service unlawfully or violate another person’s rights;
• access another person’s information or device without authorization;
• upload malicious code or disrupt, overload, probe, or bypass Service security;
• copy, modify, distribute, sell, lease, or reverse engineer the Service except where law expressly permits it;
• scrape or extract data from the Service through automated means without written permission;
• submit content you do not have the right to use; or
• present V Core output as medical advice or use the Service to cause harm.

8. Your content

You retain ownership of information, logs, notes, files, and other content you create (“User Content”). Content that remains only on your device is not transferred to V Core and requires no license to us.

If you deliberately transmit User Content to a V Core-operated support, account, sync, or other online feature, you grant V Core a non-exclusive, worldwide, royalty-free license to host, store, reproduce, technically format, transmit, and display that content only as necessary to provide, secure, maintain, and support the feature you selected. This limited license permits contracted processors to perform those functions for V Core and ends when the content is deleted, subject to lawful retention and protected backup cycles.

You represent that you have the rights needed to submit User Content and that doing so does not violate law or another person’s rights. You are responsible for reviewing your entries and keeping any separate copy you need.

9. Apple Health

If you connect V Core to Apple Health, access is optional and controlled by the permissions you grant through Apple. The current connection may request access to steps, active energy burned, and walking or running distance. The authorization screen may show read and write permissions for those types, but the current onboarding flow does not write HealthKit samples.

You can change access in the Health app or iOS Settings. Some connected features may not work without the relevant permission. HealthKit information can come from multiple apps, devices, and manual entries; V Core does not guarantee its accuracy or completeness and will not knowingly write fabricated or sample data to Apple Health. Our handling of HealthKit data is described in the Privacy Policy.

10. Subscriptions and in-app purchases

V Core may offer optional paid features, subscriptions, or in-app purchases. Before purchase, the App Store screen will disclose the price, billing period, included features, and renewal terms. Payment is charged to the Apple account used for the transaction.

You can manage or cancel an App Store subscription through your Apple account settings. Billing, renewal, cancellation, withdrawal, and refunds are subject to Apple’s terms and mandatory consumer law. Deleting V Core or any future V Core account does not automatically cancel an Apple subscription.

11. Privacy

The Privacy Policy explains how V Core handles personal information. Agreement to these Terms is separate from any consent that applicable law requires for optional sensitive-data processing.

12. Third-party services

The Service may interoperate with Apple, Supabase, Cloudflare, public media providers, or other services V Core does not control. You must comply with applicable third-party terms when using those services. Their availability and independent processing are governed by their own terms and privacy practices.

13. Service changes and availability

We may add, modify, suspend, or discontinue features to improve the Service, maintain security, comply with law, or address operational needs. We do not promise that the Service, online media, or a particular feature will always be available, uninterrupted, secure, or error-free. Where required, we will give notice of material adverse changes.

14. Disclaimer of warranties

To the maximum extent permitted by law, the Service is provided “as is” and “as available,” with all faults and without warranties of any kind. V Core disclaims implied warranties of merchantability, satisfactory quality, fitness for a particular purpose, accuracy, quiet enjoyment, and non-infringement only to the extent those warranties may lawfully be disclaimed.

Nothing in these Terms excludes warranties, remedies, duties, or statutory consumer rights that cannot lawfully be excluded.

15. Limitation of liability

To the maximum extent permitted by law, V Core, its operator, and its suppliers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, revenue, goodwill, use, or data arising from the Service.

Any exclusion or limitation applies only to the extent valid for the relationship and jurisdiction involved. It does not apply to liability that law does not permit us to exclude or limit, including, as applicable, liability for fraud, willful misconduct, gross negligence, defective services, breach of mandatory duties, or death or personal injury. Mandatory consumer rights remain unaffected.

16. Local data, suspension, and termination

You may stop using the Service and remove the app at any time. The current version does not create a remote V Core account. Removing the app generally deletes its local container, subject to device backups controlled by you or Apple, and does not remove Apple-managed purchase or Health records.

If a future version enables a remote account, you will be able to initiate account deletion in the app. We may suspend or terminate access to V Core-operated online features if you materially or repeatedly violate these Terms, create security or legal risk, or if we discontinue the feature. Where reasonably possible, we will provide notice unless prompt action is required. Provisions that by their nature should survive—including ownership, disclaimers, liability limits, and accrued rights—remain effective.

17. Changes to these Terms

We may update these Terms to reflect changes to the Service, law, or our operations. We will post the revised Terms, update the “Last updated” date, and provide additional notice where required. Material changes apply prospectively after any required notice period. If you do not agree, stop using the Service.

The English and Brazilian Portuguese versions communicate the same essential terms. The Brazilian Portuguese version includes adaptations for Brazilian law. Any inconsistency will be interpreted without reducing mandatory rights under the law applicable to you.

18. Governing law and general terms

These Terms are governed by the laws of Brazil, without depriving you of mandatory protections available in your country. If you are a consumer, a dispute may be brought in the court or forum available under mandatory consumer law, including the forum of your domicile where applicable.

If a provision is unenforceable, it will be enforced to the greatest lawful extent and the remaining provisions will continue. A failure to enforce a provision is not a waiver. You may not transfer these Terms without our consent. V Core may transfer them as part of a lawful reorganization or transfer of the Service. These Terms, the Privacy Policy, and the Apple Standard EULA form the applicable agreement for the Service.
