1. Subject Matter and Scope
1.1 These General Terms and Conditions (hereinafter "GTC") govern the contractual relationship between Systeme Digital GmbH, Wandlhamerstraße 34a, 82166 Gräfelfing, Germany, represented by its Managing Directors Staffan Schilke and Jakob Thiele, registered in the Commercial Register of the Amtsgericht München under HRB 291589 (hereinafter "Provider"), and users (hereinafter "User" or "you") of the Zeno learning app (hereinafter "App"). 1.2 The App provides students and learners with AI-powered homework assistance, practice tests, quizzes, and summaries to support the learning process. 1.3 As the provider of a learning platform, the Provider's obligation is limited exclusively to making content technically available. No specific learning outcome, improvement in grades, or passing of examinations is guaranteed. 1.4 In addition to these GTC, the terms of use of the respective app stores (Apple App Store or Google Play Store) also apply when downloading the App and making in-app purchases. 1.5 You acknowledge that the Provider alone — not the operators of the app stores (Apple/Google) — is responsible for the maintenance and support of the App.
2. Minimum Age and Parental Consent
2.1 Use of the App requires registration. Users under the age of seven are not permitted to register or use the App. 2.2 If you are at least seven years old but have not yet reached the age of 18 (limited legal capacity), the explicit consent of your parents or legal guardians is required for registration and, in particular, for entering into paid subscriptions.
3. Services and AI Disclaimer
3.1 The scope of the App's features is set out in the current description in the respective app store and within the App itself.
3.2 Special notice regarding AI-generated content: Some of the answers and learning materials provided in the App are generated automatically by artificial intelligence. Despite continuous development, it cannot be excluded that the AI may produce factually incorrect, incomplete, or misleading information ("hallucinations"). Users are advised to critically review important results and cross-check them with official learning materials.
3.3 The Provider is entitled to update, expand, or reasonably adapt the services provided at any time in order to reflect technological developments or legal requirements.
3.4 Use of the App is subject to a fair use policy. In the event of unusually high usage, the Provider reserves the right to temporarily restrict access.
4. Paid Content
4.1 Use of the App is subject to a charge. To use all features without restriction, a subscription is required. 4.2 The scope of services and the applicable pricing will be clearly displayed to you before completing a purchase within the App. 4.3 Payment processing for paid features is handled exclusively via the in-app purchase systems of Apple or Google. The payment methods stored therein apply.
5. Right of Withdrawal for Digital Content
When purchasing paid digital content, your statutory right of withdrawal expires early. This occurs once you have explicitly agreed that the Provider may begin performance of the contract before the 14-day withdrawal period has elapsed, and you have confirmed your awareness that you thereby forfeit your right of withdrawal.
6. Terms of Use
6.1 Your login credentials are personal and must be kept strictly confidential. Sharing your account with third parties is prohibited. 6.2 You are granted a simple, non-transferable right to use the App's content for your private, educational, or professional learning purposes. 6.3 The following are strictly prohibited:
- Reproducing, distributing, publishing online, or commercially exploiting learning content outside of the App.
- Using automated scripts, bots, or software to extract or manipulate the App's content.
- Using the AI features to generate content that is unlawful, racist, offensive, glorifying violence, or harmful to minors.
7. Suspension and Termination
7.1 The agreement for free use is concluded for an indefinite period and may be terminated by you at any time by deleting your account. 7.2 A paid subscription renews automatically for the selected term unless cancelled before the end of that period. Cancellation of in-app purchases must be made exclusively via the subscription management of your Apple or Google account. 7.3 The Provider reserves the right to immediately suspend your account and terminate the agreement without notice in the event of serious breaches of these GTC (e.g. account sharing).
8. Limitation of Liability
8.1 The Provider is liable without limitation for intent and gross negligence, and for injury to life, body, or health. 8.2 In the event of a slightly negligent breach of material contractual obligations (cardinal obligations), liability is limited to the foreseeable damage typical for this type of contract. Any further liability is excluded. 8.3 The Provider does not guarantee uninterrupted technical availability of the App, which may be temporarily affected by maintenance work or server outages. 8.4 The grade improvements, learning progress, and other results presented on the website, within the App, and in marketing materials are based on averages and the experiences of other users. They do not constitute a guarantee or a binding commitment. Individual results depend on various factors, in particular personal effort, regularity of use, and individual learning prerequisites. The Provider accepts no liability for the failure to achieve specific learning outcomes or grade improvements. Statements such as "students improve by an average of 2.8 grade points" are based on internal evaluations and are not to be understood as scientifically verified studies.
9. Final Provisions
9.1 The law of the Federal Republic of Germany applies. Mandatory consumer protection provisions of the country in which you habitually reside remain unaffected. 9.2 The Provider is neither willing nor obligated to participate in dispute resolution proceedings before a consumer arbitration board. 9.3 Should any provision of these GTC be invalid, the validity of the remaining provisions shall not be affected. 9.4 The Provider reserves the right to amend these GTC with effect for the future. You will be notified of any changes in good time (e.g. by email or upon the next launch of the App). Changes are deemed accepted if you do not object within two weeks of receiving the notification or continue to use the App after being informed of the changes.
