Terms of Use

1. Acceptance and who may use Lena

These Terms of Use are an agreement between you and LenaCare, operating as Lena. They apply to the Lena app for iOS and Android, the Lena Doctor Portal, and related services. By creating an account or using Lena, you agree to these Terms and the Privacy Policy. If you do not agree, do not use Lena.

You must be at least 16 years old to use Lena. We do not knowingly collect data from anyone under 16. You must provide accurate account information and keep access to your Apple or Google sign-in account secure. You are responsible for activity on your Lena account unless it results from our breach of security.

2. What Lena provides

Lena is a clinical-grade AI women’s health companion. Features may include AI chat with streaming responses, menstrual-cycle tracking, algorithmic phase and ovulation predictions, health quizzes and reports, weekly and monthly AI-generated cycle reports, workout programs, recipes, doctor messaging where available, optional Apple Health or Health Connect import, and push notifications. Lena is currently available on iOS and Android in English, French, Arabic, Spanish, and Portuguese. Features may vary by location, language, device, and plan.

3. Important medical disclaimer

Lena does not practise medicine and is not a medical device, emergency service, or substitute for a qualified clinician. AI-generated chats, reports, quizzes, summaries, workout suggestions, nutrition suggestions, recipes, and other content are for general information and wellbeing support only. They are not medical advice, diagnosis, treatment, a prescription, or a guarantee of any result.

Cycle, phase, fertile-window, and ovulation predictions are estimates based on the information available to Lena. They are not contraception, should not be used to prevent pregnancy, and are not a fertility diagnosis or a substitute for fertility testing or clinical care. Do not make health, medication, exercise, nutrition, pregnancy, or fertility decisions solely on Lena’s output. Seek advice from a qualified professional for individual concerns.

For urgent symptoms or an emergency, contact your local emergency service immediately. Do not use Lena or Doctor Portal messaging for emergencies or time-critical care.

4. Doctor Portal and clinician messaging

The Doctor Portal helps you communicate with a clinician you choose to connect with. You grant explicit, separate consent before that clinician can view the record you choose to share, and you may revoke access in Lena’s settings. Lena facilitates this communication; it does not employ the clinician unless expressly stated, does not itself provide clinical care, and does not make clinical decisions on the clinician’s behalf.

The clinician is responsible for their own professional advice, clinical records, and legal obligations. Doctors using the Portal are bound by medical confidentiality under French law. Lena may prepare an AI summary or suggested reply, but the clinician reviews, edits, and decides whether to send any clinical communication.

5. Subscriptions, billing, and promotional access

Lena subscriptions are sold exclusively through in-app purchase on the Apple App Store or Google Play, in monthly and annual terms. Each purchase is also governed by the terms of the store you buy from. Prices, available plans, and applicable taxes are shown in the App before you confirm purchase. Payment is charged to your Apple Account or Google Play account at confirmation.

Your subscription renews automatically unless you turn off auto-renewal at least 24 hours before the end of the current period. For App Store subscriptions, Apple will charge the renewal within 24 hours before the period ends. You can manage or cancel your subscription in your Apple Account settings or your Google Play account. Refunds are handled by Apple or Google, depending on the store you bought from, under that store’s refund policy, not by Lena.

We may offer promotional complimentary access, including a three-month period. Promotional access requires no payment instrument and does not automatically convert to a paid plan. It ends on the date shown in the App unless we tell you otherwise.

6. Apple-specific terms

These Terms are between you and LenaCare, not Apple. LenaCare, and not Apple, is responsible for Lena and its content, including support. Apple has no obligation to provide maintenance or support, and no warranty obligation for Lena. If Lena fails to conform to an applicable warranty, you may notify Apple and Apple may refund the purchase price; Apple has no further warranty obligation to the fullest extent permitted by law.

LenaCare, not Apple, is responsible for addressing product-liability claims, legal-compliance claims, and claims that Lena infringes a third party’s intellectual-property rights. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. You represent that you are not in a US-embargoed country and are not listed on a US government prohibited or restricted-party list.

7. Privacy and your health data

Our Privacy Policy explains how we collect, use, protect, share, retain, and delete personal data, including health data treated as special category data under Article 9 GDPR. It also explains your rights, including access, correction, erasure, and withdrawal of consent. The Privacy Policy forms part of these Terms and takes priority for data-handling questions.

8. Your content and licence

You retain your rights in the information, messages, health entries, photos, and other content you provide. You give Lena a limited, non-exclusive licence to host, process, reproduce, and display that content only as needed to operate, secure, improve, and provide the Services in line with the Privacy Policy. You confirm you have the rights needed to provide your content and that it does not violate anyone else’s rights.

9. Acceptable use

Do not misuse Lena. In particular, do not break the law; impersonate another person; share another person’s private information without permission; use Lena to harass, exploit, or harm anyone; interfere with security or access controls; attempt to reverse engineer or scrape the Service; upload malicious code; use automated systems to overload the Service; or use Lena’s content as a substitute for emergency or professional medical care.

10. Intellectual property

Lena, its software, design, text, graphics, reports, and other service materials are owned by or licensed to LenaCare and protected by applicable intellectual-property laws. We give you a personal, revocable, non-transferable licence to use Lena for its intended purpose while you comply with these Terms. You may not copy, sell, modify, distribute, or create derivative works from Lena except where the law permits or we give written permission.

11. Third-party services

Lena relies on selected third-party providers. OpenAI and Google (Gemini) support AI processing; user content is not used to train their models. PostHog supports product analytics, MailerLite supports transactional email, and Firebase supports push messaging. Lena does not use advertising or attribution SDKs. Third-party services may have their own terms; our Privacy Policy explains the related data processing.

12. No warranties and limits on liability

To the fullest extent permitted by law, Lena is provided as is and as available. We do not promise that it will be uninterrupted, error-free, accurate for every person, or suitable for every purpose. We do not exclude liability that cannot legally be excluded, including liability for fraud, deliberate wrongdoing, or death or personal injury caused by negligence where applicable law does not allow exclusion.

Subject to that, LenaCare will not be liable for indirect, incidental, special, or consequential loss, or loss arising from reliance on AI guidance, predictions, workout or nutrition recommendations, or clinician communications, except where that limitation is not allowed by law.

13. Suspension and termination

You may stop using Lena and delete your account at any time through the App. We may suspend or end access where reasonably necessary to protect users, comply with law, address security risks, or enforce these Terms. Ending access does not change any rights or obligations that by their nature continue, including intellectual-property, liability, and dispute provisions. Data deletion and retention are governed by the Privacy Policy.

14. Changes to these Terms

We may update these Terms when Lena changes, the law changes, or we need to clarify them. For material changes, we will give reasonable notice in the App, by email, or both before they take effect. The updated Terms will show a new version and effective date. If you continue to use Lena after the effective date, you accept the updated Terms, unless the law requires another form of consent.

15. Governing law and disputes

These Terms are governed by the laws of France. The courts of Paris will have jurisdiction, subject to any mandatory consumer protections that apply where you live.

16. Contact, version, and effective date
