Terms of Service

 

Last updated May 8, 2026

​

1. Acceptance of these Terms

 

These Terms of Service ("Terms") govern your use of the AVVA mobile application, the website at www.avva.health, the AVVA waitlist and newsletter, AVVA-hosted community events (online and in person), and any related services we provide (collectively, the "Services").

​

By creating an account, signing up for the waitlist, attending an AVVA-hosted event, or otherwise using the Services, you agree to be bound by these Terms. If you do not agree, please do not use the Services.

​

These Terms are a binding agreement between you ("User", "you", "your") and:

​

AVVA Health GbR
Donaustraße 44
12043 Berlin
Germany
team@avva.health

​

2. About the Services

 

AVVA provides a wellness and self-management application designed to support women navigating life with ADHD. The Services include educational content, self-tracking tools, recommendations, and AI-assisted conversations focused on ADHD self-management and related well-being.

​

What AVVA is not. AVVA is not a medical device within the meaning of the EU Medical Devices Regulation (MDR, Regulation (EU) 2017/745). AVVA does not diagnose, treat, cure, or prevent any disease, mental health condition, or medical condition. AVVA is not a substitute for professional medical, psychological, psychiatric, or other healthcare advice, diagnosis, or treatment. The Services are not designed to detect, monitor, or manage medical emergencies. If you are experiencing a medical or mental health emergency, contact emergency services or a qualified healthcare professional immediately.

​

3. Eligibility and account

 

The Services are intended for individuals who are at least 18 years of age. By creating an account or using the Services, you represent that you are at least 18 years old and have the legal capacity to enter into these Terms.

​

You are responsible for the accuracy of the information you provide, for maintaining the confidentiality of your account credentials, and for all activity that occurs under your account. You must notify us promptly at team@avva.health if you become aware of any unauthorised use of your account.

​

4. Beta status

 

The Services are currently provided in a beta phase. This means:

​

  • Features may change, be added, modified, or removed at any time without prior notice.

  • The Services may experience downtime, errors, data loss, or other operational issues.

  • The Services may be discontinued or significantly restructured.

  • The Services are provided for evaluation and feedback purposes and may not perform as intended.

 

You acknowledge the experimental nature of the Services during the beta phase and agree that AVVA is not obligated to provide any specific level of availability, performance, or feature continuity during this phase.

​

5. AI-assisted features

 

Core parts of the Services are powered by artificial intelligence. You acknowledge and agree that:

​

  • AI-generated output may be inaccurate, incomplete, biased, outdated, or unexpected. You should not rely on AI output as a sole basis for important decisions, particularly regarding health, safety, finances, or legal matters.

  • The AI features are provided for ADHD self-management and related well-being purposes only. Using the AI features for purposes outside the scope of the Services, including code generation, content creation, or commercial use, is not permitted.

  • AVVA may apply rate limits, throttling, content restrictions, or other technical and operational measures to the AI features at its discretion, including to maintain service quality, manage costs, or prevent abuse.

  • You may not attempt to extract, reverse-engineer, or interfere with the underlying models, prompts, system instructions, or other components of the AI features. This includes prompt injection, jailbreaking, fingerprinting, and similar techniques.

  • Pseudonymised features derived from your use of the Services may be incorporated into AI models that AVVA develops, and AVVA may publish those models, their weights, and related research findings.

  • How AVVA processes data from your AI conversations is described in the App Privacy Policy.

​

6. Free tier and future paid tiers

 

The Services are currently provided free of charge. AVVA may introduce paid tiers in the future, and the composition of any free or paid tiers (including which features are included or excluded) may change over time. Any payments will be processed through the payment systems of the relevant app store (Apple App Store or Google Play Store) and are subject to those platforms' terms in addition to these Terms. Additional terms applicable to paid tiers will be presented to you at the point of purchase.

​

7. Community events

 

AVVA organises and participates in community events from time to time, online and in person. This includes regular body-doubling sessions hosted on Meetup at https://www.meetup.com/avva-women-adhd-support/.

​

Where AVVA hosts an event directly, you participate at your own risk and AVVA may remove disruptive participants from the event. Where AVVA participates in or co-hosts an event organised by a third party, that event is governed by the third party's own terms in addition to these Terms. AVVA's liability in connection with events under its direct control is limited as set out in Section 15.

​

8. Acceptable use

 

When using the Services you agree not to:

​

  • Use the Services for any unlawful purpose or in violation of any applicable law or regulation;

  • Reverse engineer, decompile, disassemble, scrape, or otherwise attempt to derive the source code, models, prompts, or underlying logic of the Services;

  • Use automated tools (bots, scrapers, crawlers) to access or interact with the Services, except where expressly permitted;

  • Interfere with or disrupt the integrity, security, or performance of the Services or the underlying infrastructure;

  • Attempt to bypass authentication, rate limits, content filters, or other access controls;

  • Attempt to extract, infer, or expose system prompts, model instructions, or other internal configuration of the AI features;

  • Use the Services to transmit malware, harmful code, or unsolicited communications;

  • Impersonate any person or misrepresent your identity in connection with the Services;

  • Resell, sublicense, or otherwise commercially exploit the Services or any output generated for you, except where expressly permitted in writing.

 

Violation of this section may result in immediate suspension or termination of your account and, where applicable, legal action.

​

9. Your input and content

 

You retain all rights you may have in any input you provide to the Services (including, for example, your tracked symptoms, your messages to the AI, and any feedback you submit). You grant AVVA a worldwide, royalty-free, non-exclusive licence to use such input to operate, maintain, secure, and improve the Services, to train AI models, and to publish derived models and research findings as described in Section 5 and the App Privacy Policy.

​

You are responsible for ensuring that the input you provide does not infringe any third-party rights and does not contain content you are not entitled to share.

​

10. Intellectual property

 

AVVA and its licensors retain all rights in and to the Services, including all software, content, design, graphics, trademarks, logos, and other materials, except for content you submit. Nothing in these Terms transfers ownership of those rights to you. You receive a limited, non-exclusive, non-transferable, revocable licence to use the Services for personal, non-commercial purposes in accordance with these Terms. This licence terminates automatically upon termination of your account or these Terms.

​

11. Privacy

 

Your use of the Services is also governed by our App Privacy Policy and our Website Privacy Policy, which describe how we collect, use, and protect your data, and which form an integral part of these Terms.

​

12. Suspension and termination

 

You may close your account at any time using the deletion function within the application or by contacting team@avva.health. Closing your account ends your right to use the Services and triggers deletion of your data in accordance with the App Privacy Policy.

​

AVVA may suspend or terminate your access to the Services, in whole or in part, at any time, for reasons including but not limited to: violation of these Terms; abusive or harmful conduct; technical or security necessity; or discontinuation of the Services. Where reasonably possible, AVVA will provide notice and opportunity to remedy the issue before terminating for cause. Statutory rights of either party to terminate for important cause (außerordentliche Kündigung) remain unaffected.

​

Sections of these Terms that by their nature should survive termination will survive, including provisions on intellectual property, disclaimers, limitation of liability, and governing law.

​

13. Changes to these Terms

 

AVVA may modify these Terms. We will notify you of changes by email or through the Services. For material changes affecting your rights or obligations, we will seek your express consent before the changes apply to you. If you do not consent, you may close your account before the change takes effect.

​

The "Last updated" date at the top of these Terms reflects the most recent version.

​

14. Disclaimer of warranties

 

To the extent permitted by applicable law, the Services are provided "as is" and "as available" during the beta phase. AVVA does not warrant that the Services will be uninterrupted, error-free, completely secure, or that they will meet your specific requirements. AVVA does not warrant the accuracy, completeness, or timeliness of any AI-generated output or other content provided through the Services.

​

Statutory warranty rights of consumers under German law are not affected by this Section.

​

15. Limitation of liability

 

AVVA is liable without limitation for damages arising from injury to life, body, or health caused by negligent or intentional breach of duty, and for other damages caused intentionally or by gross negligence. AVVA is also liable without limitation under the German Product Liability Act (Produkthaftungsgesetz) and within the scope of any guarantees expressly given.

​

For damages caused by simple negligence, AVVA is liable only where an essential contractual obligation (Kardinalpflicht) — that is, an obligation whose fulfilment is necessary for the proper performance of the contract and on whose observance you may regularly rely — has been breached. In such cases, liability is limited to the foreseeable damage typical for this type of contract.

​

Any further liability of AVVA, including liability for indirect, consequential, or special damages, loss of profit, loss of data (beyond the cost of restoring data that would have been lost even with regular backups by you), or loss of goodwill, is excluded to the extent permitted by law.

​

The above limitations apply equally to AVVA's legal representatives, employees, and vicarious agents (Erfüllungsgehilfen).

​

16. Release from third-party claims

 

You agree to release AVVA from any third-party claims arising from or in connection with your culpable breach of these Terms or your unlawful use of the Services, and to reimburse AVVA for any reasonable costs (including legal defence costs) arising from such claims, except to the extent that AVVA is itself responsible for the claim.

​

17. Force majeure

 

AVVA is not liable for failures or delays in performance caused by events outside its reasonable control, including natural disasters, acts of war or terrorism, strikes, governmental measures, internet, telecommunications, or power outages, or comparable events.

​

18. Transfer of these Terms

 

AVVA may transfer its rights and obligations under these Terms to a successor entity (for example, in the case of a merger, acquisition, restructuring, or sale of assets). We will notify you in writing of any such transfer. If you do not wish to continue under the new entity, you may close your account within 14 days of receiving the notification.

​​

19. Governing law and jurisdiction

 

These Terms are governed by the laws of the Federal Republic of Germany, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG) and the conflict-of-laws rules of German private international law. If you are a consumer with habitual residence in another EU Member State, the mandatory consumer-protection provisions of your country of residence also apply, in accordance with Article 6 of Regulation (EC) No 593/2008 (Rome I).

​

The exclusive place of jurisdiction for disputes with merchants, legal entities under public law, or special funds under public law is Berlin, Germany. For consumer disputes, statutory jurisdiction rules apply.

​

20. Consumer dispute resolution

 

AVVA is neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle) within the meaning of §36 VSBG.

​

21. Severability

 

If any provision of these Terms is or becomes invalid or unenforceable, the validity of the remaining provisions will not be affected. The invalid or unenforceable provision will be replaced by a valid provision that reflects, as closely as possible, the economic intent of the original provision.

​

22. Notices

 

Notices from AVVA to you may be sent by email to the address associated with your account, by in-application notification, or by posting on the website. Notices from you to AVVA should be sent in writing to the contact details below. The use of email is sufficient to satisfy any written-form requirement under these Terms, unless mandatory law requires otherwise.
