Terms of Service

Last updated: July 2026

Note: These Terms of Service are a convenience translation. In case of discrepancies, the German version (Allgemeine Geschäftsbedingungen) prevails.

for the OONVAA App

Section 1: Scope and Provider

(1) These Terms of Service (“Terms”) apply to the use of the mobile application “OONVAA” (the “App”), including all free and paid features.

(2) The provider of the App is: Nina Hoch, KiTrinity, c/o POSTFLEX PFX-914-205, Emsdettener Straße 10, 48268 Greven, Germany, E-mail: info@kitrinity.io (the “Provider” or “we”).

(3) Paid features (see Section 7) are purchased via the respective app store (Google Play and the Apple App Store). For the purchase transaction itself, in particular payment processing, invoicing and refunds, the terms of the respective store operator apply in addition (see Sections 12 and 13). These Terms govern the use of the App and the relationship between you and the Provider.

(4) Deviating terms of users do not apply.

Section 2: Description of Services

(1) OONVAA is an app for self-reflection and self-help regarding your own relationship with alcohol. The App supports three paths: setting and tracking a limit, observing your own consumption, and abstinence.

(2) The features include, among others: timers and milestones, mood and craving log, diary, morning routines, an optional self-assessment (AUDIT / AUDIT-C) and, in the Pro version, the AI companion Sam and further additional features.

(3) The App follows a privacy-first approach: no registration and no account are required. Content you create is stored locally on your device. Details of data processing are governed by the Privacy Policy, available at kitrinity.io/en/privacy.html. The Privacy Policy does not form part of these Terms.

(4) The specific range of features results from the current description in the app store and in the App. The Provider continuously develops the App further (see Section 9).

Section 3: Important Medical Notice, Not a Medical Device

(1) OONVAA is a tool for self-reflection. The App is not a medical device, does not provide diagnoses, is not a therapy and does not replace medical, psychotherapeutic or addiction-medicine advice or treatment.

(2) The optional self-assessment included in the App (AUDIT / AUDIT-C) is a recognised screening instrument for self-evaluation. The result is not a diagnosis.

Important warning: In the case of physical alcohol dependence, abruptly stopping consumption can be medically dangerous (risks include seizures and delirium). If you have been drinking heavily or over a long period, be sure to speak with a doctor before reducing or withdrawing. Withdrawal belongs under medical supervision.

(4) The App is not intended for use in emergencies or acute crises. In medical emergencies, call the emergency number 112. In mental health crises you can reach, free of charge and around the clock: Telefonseelsorge Germany 0800 111 0 111, Austria 142, Switzerland 143.

(5) You use the App at your own responsibility. Decisions about your relationship with alcohol are yours; the App provides prompts and tools, but no medical instructions.

Section 4: AI Companion Sam

(1) Sam is an AI companion based on a language model (Mistral AI). Sam is not a human being, not a doctor, not a therapist and not a crisis intervention service.

(2) AI-generated answers can be incorrect, incomplete or inappropriate. Content from Sam does not constitute medical, psychological or legal advice. Do not rely on statements from Sam for health decisions; seek professional help instead (see Section 3).

(3) Using Sam requires separate, explicit consent to the associated data processing, which is obtained within the App. Details are governed by the Privacy Policy.

(4) The use of Sam is subject to a fair-use quota (currently a certain number of messages per month, displayed in the App’s settings). The quota serves to ensure stable operation for all users. Any change to the quota to the detriment of ongoing paid contracts is governed by Section 9(3).

(5) It is prohibited to misuse Sam, in particular to generate unlawful content, to circumvent protective mechanisms of the App or of the language model, or to impair the service through automated mass requests.

Section 5: Requirements for Use and Minimum Age

(1) Use of the App requires a minimum age of 16 years.

(2) Minor users (16 to 17 years) may make paid purchases (Section 7) only with the consent of their legal guardians. The provisions of Sections 106 et seq. of the German Civil Code (BGB) remain unaffected.

(3) Use requires a compatible device with a supported operating system. Certain features (in particular Sam and the verification of purchase status) require an internet connection; you bear any connection costs yourself.

Section 6: Licence and Local Data

(1) By installing the App, you receive a simple, non-exclusive, non-transferable and non-sublicensable right to use the App on your own devices for private, non-commercial purposes. If you purchase the Pro version, this right extends to the Pro features in accordance with Section 7.

(2) The following in particular are not permitted: reproduction, modification, distribution or making the App publicly available beyond the contractual purpose; reverse engineering, decompiling or disassembling, except where expressly permitted by law (Section 69e of the German Copyright Act, UrhG); and circumventing technical protection measures.

(3) Content you create in the App is stored exclusively locally on your device. Your content is not stored on our servers. This also means: if you uninstall the App, reset your device or lose it, your content may be irretrievably lost. You are responsible for backing up your data (e.g. via your device’s backup function).

Section 7: OONVAA Pro: Subscriptions and Lifetime Licence

(1) Certain features of the App are reserved for the paid Pro version. The offer, prices and terms result from the presentation in the respective app store or in the App at the time of purchase.

(2) Subscriptions (monthly or yearly) renew automatically for the respective term unless cancelled before the end of the current period via the subscription management of the respective app store. Cancellation takes place exclusively via the settings of your store account:

Cancellation towards the Provider is neither required nor technically possible for store subscriptions.

(3) The Lifetime licence is a one-time purchase without recurring costs. It grants the right to use the Pro features for the period during which OONVAA is offered and technically supported by the Provider. “Lifetime” refers to the lifetime of the product OONVAA, not to the lifetime of the user. Should the Provider discontinue the App, this will be announced in the App with reasonable notice, as a rule at least six months in advance. Statutory warranty rights (Sections 327 et seq. BGB) remain unaffected.

(4) Price changes apply only for the future and take effect for ongoing subscriptions only upon the next renewal; the mechanisms of the respective app store apply (including information and, where required, consent).

Section 8: Right of Withdrawal for Digital Content

(1) Consumers are in principle entitled to a statutory right of withdrawal of 14 days when purchasing digital content.

(2) The right of withdrawal expires for contracts for the supply of digital content not delivered on a physical medium if the Provider has begun performing the contract after you have expressly consented to performance beginning before the end of the withdrawal period and you have confirmed your knowledge that the right of withdrawal thereby expires (Section 356(5) BGB).

(3) The purchase process, including obtaining this consent and any refunds, is handled via the respective app store. Please therefore address withdrawals and refund requests to the respective store; their procedures apply in addition (see Sections 12 and 13).

Section 9: Availability, Updates and Changes

(1) The core features of the App are available offline. Online components (in particular Sam and the verification of purchase status) require the availability of our servers or the servers of our service providers. There is no entitlement to uninterrupted availability of the online components; maintenance, updates and disruptions may lead to temporary restrictions. We endeavour to keep maintenance windows short.

(2) The Provider supplies updates that are necessary to maintain the conformity of the App (Section 327f BGB) and informs you of their availability. Installing the updates is your responsibility; if you fail to install them, liability for defects may lapse in accordance with Section 327f(2) BGB.

(3) The Provider may further develop the App and change, supplement or discontinue features, provided this is reasonable for you. Changes to paid features that go beyond what is necessary to maintain conformity are made only under the conditions of Section 327r BGB (valid reason, no additional costs for you, clear and comprehensible information; in the case of significant impairment, additionally timely notice and, where applicable, a right of termination).

Section 10: Liability

(1) The Provider is liable without limitation for damage resulting from injury to life, body or health based on a breach of duty by the Provider or its vicarious agents, for damage based on intent or gross negligence, and in accordance with the German Product Liability Act.

(2) In the case of a slightly negligent breach of essential contractual obligations (cardinal obligations), i.e. obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely, liability is limited to the foreseeable damage typical for the contract.

(3) In all other respects, liability for slight negligence is excluded.

(4) The above limitations do not apply where the Provider has fraudulently concealed a defect or has assumed a guarantee. Statutory rights regarding digital products (Sections 327 et seq. BGB) remain unaffected.

(5) For clarification: content and recommendations of the AI companion Sam do not constitute advice within the meaning of Sections 3 and 4. Your own responsible decisions about your relationship with alcohol and their consequences lie outside the Provider’s sphere of responsibility. The liability provisions of paragraphs 1 to 4 remain unaffected.

Section 11: Community Feature (in Preparation)

(1) A community feature is planned but not currently active.

(2) Before the community is enabled, these Terms will be supplemented with rules of use (in particular rules of conduct, moderation, reporting and blocking options). Participation will be voluntary; the rest of the App remains usable without the community.

Section 12: Additional Terms for the Apple App Store

If the App is obtained via the Apple App Store, the following applies in addition:

(1) Parties. These Terms are concluded solely between you and the Provider, not with Apple. The Provider, not Apple, is solely responsible for the App and its content.

(2) Scope of Licence. The licence under Section 6 is limited to a non-transferable licence to use the App on any Apple-branded products that you own or control, and as permitted by the Usage Rules set forth in the Apple Media Services Terms and Conditions.

(3) Maintenance and Support. Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the App. These are the sole responsibility of the Provider.

(4) Warranty. The Provider is solely responsible for any product warranties. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App. Any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty are the sole responsibility of the Provider.

(5) Product Claims. The Provider, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession and/or use of the App, including, but not limited to: (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy, or similar legislation.

(6) Intellectual Property Rights. In the event of any third-party claim that the App infringes that third party’s intellectual property rights, the Provider, not Apple, will be solely responsible for the investigation, defence, settlement and discharge of any such claim.

(7) Legal Compliance. You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

(8) Contact. For questions, complaints or claims with respect to the App, please contact: Nina Hoch, KiTrinity, c/o POSTFLEX PFX-914-205, Emsdettener Straße 10, 48268 Greven, Germany, e-mail: info@kitrinity.io.

(9) Third-Party Terms. You must comply with applicable third-party terms of agreement when using the App.

(10) Third-Party Beneficiary. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary thereof.

Section 13: Additional Terms for Google Play

If the App is obtained via Google Play, the following applies in addition:

(1) Parties. These Terms are concluded solely between you and the Provider. Google is not a party to these Terms and is not responsible for the App or its content.

(2) Purchase and Payment. Paid features are purchased via Google Play. The Google Play Terms of Service and the Google Payments Terms of Service apply in addition to the purchase process, payment and invoicing.

(3) Cancellation. You manage and cancel subscriptions in the Google Play app under: Profile → Payments and subscriptions → Subscriptions. Cancellation takes effect at the end of the current billing period; periods already begun are not refunded on a pro rata basis unless mandatory law provides otherwise.

(4) Refunds. Please address refund requests to Google Play; the Google Play refund policy applies. Statutory warranty and withdrawal rights towards the Provider (Sections 8, 10) remain unaffected.

(5) Maintenance and Support. Maintenance and support for the App are the sole responsibility of the Provider, not Google. For matters concerning the App, please contact info@kitrinity.io.

Section 14: Final Provisions

(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. If your habitual residence is in another state, mandatory consumer protection provisions of that state remain unaffected.

(2) The Provider is neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board within the meaning of the German Consumer Dispute Resolution Act (VSBG).

(3) The Provider may amend these Terms with effect for the future where this is necessary for valid reasons (e.g. changes in legislation, case law, new features) and does not unreasonably disadvantage you. You will be informed of changes in good time in the App or on the website. Material changes to your detriment in ongoing paid contracts require your consent or are governed by Section 327r BGB.

(4) Should individual provisions of these Terms be or become invalid in whole or in part, the validity of the remaining provisions remains unaffected. The statutory provisions take the place of the invalid provision.
