Legal
Terms of Use
Last updated: October 4, 2026
These Terms of Use govern your use of the Prevena mobile app, its Apple Watch app and related websites (the "Service"). By using the Service, you agree to these terms. Please read them carefully.
1. Parties
The Service is provided by Lynex Studio LLC ("Prevena", "we", "us"). These Terms are a legal agreement between you (the "User") and Prevena. You can contact us at info@prevena.app.
2. Eligibility and age limit
You must be at least 13 years old to use Prevena. Users aged 13 to 18 may use the Service only with the consent and supervision of a parent or legal guardian. We may close any account that does not meet these age requirements.
You confirm that you have the legal capacity to enter into a binding contract under the laws where you live.
3. Account and security
Prevena creates your account with a random identifier linked to your device and may ask for some information to do so. You are responsible for the security of the devices linked to your account and for all activity through it.
If you suspect unauthorised access to your account, tell us right away at info@prevena.app.
4. Limited license
As long as you follow these Terms, Prevena grants you a limited, non-exclusive, non-transferable, non-sublicensable and revocable license to use the Service for personal, non-commercial purposes.
You agree not to: reverse engineer, copy, modify, create derivative works from, rent, sell or commercially redistribute the app; access the Service with automated tools (scrapers, bots); use the Service to create content that infringes others' rights or is unlawful, defamatory, harassing or harmful; or try to get around the Service's security measures.
5. Subscriptions, fees and payment
Prevena is free to download; using the app requires a paid subscription. Subscriptions are bought through your device's app store (Apple App Store or Google Play) and are subject to that store's terms.
- Subscriptions renew automatically through the store unless cancelled.
- You are charged the amount shown in the app and in the store at the time of purchase.
- If a plan starts with a free trial, it becomes a paid subscription when the trial ends unless you cancel at least 24 hours before.
- Cancellation takes effect at the end of the current subscription period; there are no refunds for partial periods.
- Refund requests are handled under the refund policy of the store where you bought the subscription.
- Prices and plan features may change; we will tell you about such changes in advance.
You can manage and cancel your subscription at any time in your device's store settings.
6. Medical disclaimer
Prevena is not a medical device and is not intended to diagnose, treat, cure or prevent any disease. The daily outlook, possible links, medication-day counts, relief routines, AI replies and all other content in the app are for information only.
Relief routines are general self-care exercises; stop if you feel worse. Get emergency help right away if a headache comes on suddenly and is the worst of your life, comes with weakness in your face, arm or leg, or comes with a fever together with a stiff neck, and for numbness, trouble speaking or vision loss that is new to you, lasts longer than an hour or is different from your usual aura.
Always talk to a healthcare professional before making decisions about your health. In an emergency, call your local emergency number or go to the nearest medical facility. Prevena is not liable for the consequences of decisions made on the basis of information in the app.
7. User content
Content you create through the Service, such as attack records, journal entries, chat messages and profile information ("User Content"), belongs to you. You grant Prevena a worldwide, royalty-free, limited license to host, store, analyse (including for the daily outlook and the chat) and show your content back to you, so that we can provide the Service and create your reports.
You are responsible for the accuracy and lawfulness of your User Content. You agree not to use the Service to create content that infringes others' rights or is harmful, misleading or unlawful.
8. AI features
Prevena uses AI models (Anthropic's Claude) for the daily outlook and the chat assistant. These features need your explicit consent; if you don't give it, the rest of the Service keeps working. The chat is always labelled as AI.
AI output is probabilistic and may contain errors, gaps or misleading information. It is not medical advice. The outlook is shown as Low, Medium or High and never gives a probability or a date for an attack. You are responsible for decisions you make based on these features. Details of AI data processing are in the Privacy Policy.
9. Intellectual property
Apart from User Content, the Prevena brand, logo, app design, interface, text, images, source code and all software components belong to Lynex Studio LLC and are protected by intellectual property laws.
Beyond the limited license in these Terms, no rights to Prevena's intellectual property are transferred to you.
10. Prohibited uses
When using the Service, you agree not to:
- Break applicable laws, regulations or the rights of others
- Create fake accounts on behalf of others or misrepresent your identity
- Use viruses, malicious code or network attacks that could harm the Service, its servers or other users
- Try to get around the Service's security, authentication or metering
- Use automated tools to extract data from the Service in bulk
- Harass, threaten or otherwise disturb other users
- Use the Service for commercial resale, white-labelling or agency-type purposes
11. Third-party services
Prevena relies on third-party services to work: DigitalOcean (hosting), Anthropic (AI), Open-Meteo (weather), RevenueCat (subscriptions), Apple App Store and Google Play (payments), Amplitude (usage analytics), Sentry (error reports) and Meta (advertising measurement). Their terms and privacy policies may also apply to you. Prevena is not responsible for the content or performance of third-party services. The Privacy Policy explains what data is shared with them.
12. Suspension and termination
If we find that you have broken these Terms or applicable law, we may suspend or permanently close your account without notice.
You can close your account at any time in the app under Profile > Delete My Account, or by emailing info@prevena.app. Deleting your account in the app removes your data from our live database within 24 hours and from backups within 14 days; the Privacy Policy has the details.
13. Disclaimer of warranties
To the fullest extent the law allows, the Service is provided "as is" and "as available". Prevena makes no express or implied warranty that the Service will be uninterrupted, error-free, secure or fully suited to your needs.
We do not guarantee the accuracy, completeness or fitness for a particular purpose of the information, outlooks or suggestions in the Service.
14. Limitation of liability
To the fullest extent the law allows, Prevena is not liable for any indirect, incidental, special, punitive or consequential damages (such as lost profits, lost data or business interruption) arising from your use of the Service.
In any case, Prevena's total liability is limited to the greater of (a) the total amount you paid for the Service in the 12 months before the event that gave rise to the claim, or (b) USD 100.
15. Indemnification
You agree to indemnify, defend and hold harmless Prevena, its officers and employees against any claims, lawsuits, damages, costs (including attorneys' fees) and losses arising from your use of the Service, your User Content or your breach of these Terms.
16. Changes to these Terms
We may update these Terms from time to time. For significant changes we will tell you in the app and update the date at the top of this page. If you keep using the Service after a change, you accept the updated Terms.
17. Governing law and jurisdiction
These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict of law rules. For users in Turkey, the mandatory provisions of Turkish consumer protection law remain reserved.
The courts and enforcement offices where the user lives also have jurisdiction over disputes arising from these Terms.
18. General provisions
If any provision of these Terms is found invalid or unenforceable, the remaining provisions stay in full force. If Prevena does not exercise a right under these Terms, that is not a waiver of the right.
These Terms, together with the Privacy Policy, are the entire agreement between you and Prevena and replace any earlier oral or written understanding.
