Terms of Use

Last updated: July 3, 2026

These terms govern your use of the Litux website and application (the "Service"), operated by Franco Medero, Munich, Germany (see Impressum). By using the Service you accept these terms.

1. The Service

Litux is browser-based statistical software for economic analysis. Computation runs locally in your browser; your datasets stay on your device unless you explicitly enable cloud sync or AI features (see the Privacy Policy). The Service is currently offered free of charge and in active development ("beta"): features may change, be limited (for example through usage credits), or be discontinued.

2. Accounts and acceptable use

You may use Litux as a guest or with an account. You are responsible for keeping your credentials safe. You must not: misuse the Service to attack, overload, or reverse the infrastructure; attempt to circumvent usage limits or credit metering; or use the Service to process or generate unlawful content.

3. Your content and copyright — your responsibility

"Your content" means everything you bring into the Service: datasets, files, project names and labels, and any text, images, screenshots, or documents you attach to the AI coach chat or share with other users.

• You keep ownership. We claim no rights to your content.
• You warrant that you have the necessary rights (ownership, license, or a legal permission such as research use) to every piece of content you upload, attach, or share — including images pasted into the AI coach chat — and that your content does not infringe third-party copyrights, database rights, personality rights, or data-protection rights, and is not otherwise unlawful.
• Limited processing license. Solely to operate the Service, you grant us the technical right to store (encrypted, where sync is enabled) and transmit your content — including transmission of attached content to our AI model provider when you invoke AI features. We do not publish your content and do not use it to train AI models.
• Indemnity. If a third party raises claims against us because content you uploaded or shared infringes their rights, you will indemnify us against the reasonable costs of such claims, unless you were not responsible for the infringement.

4. Notice and takedown

If you believe content shared through the Service (for example, a shared project) infringes your rights, notify us at mederofranco21@gmail.com with: a description of the work, the location of the allegedly infringing material, your contact details, and a statement that you believe in good faith that the use is unauthorized. We review notices promptly and remove or disable access to unlawful content once we become aware of it. For users in the United States, this address also serves as our designated copyright (DMCA-style) notice contact.

5. AI features — transparency and limits

• You are interacting with an AI system. The AI coach, AI command bar, and AI narratives are generated by a large language model (Anthropic Claude), not by a human.
• AI output can be wrong. Generated explanations, code, narratives, and suggested pipeline steps are AI-generated content and may contain errors. Verify results before relying on them — especially before using them in academic work, publications, or decisions. The Service provides software tooling, not statistical, academic, financial, or legal advice.
• Outputs are yours to use. To the extent we hold any rights in AI output generated for you, we assign them to you. You are responsible for how you use outputs, including compliance with your institution's academic-integrity rules.
• Attachments. Content you attach to the AI chat is sent to the AI model provider (see the Privacy Policy). Do not attach content you have no right to process or that contains other people's personal data.

6. Availability and changes

We aim for high availability but do not guarantee uninterrupted, error-free operation. Because your data lives in your browser by default, clearing browser storage can delete local projects — export or sync anything you cannot afford to lose. We may modify or discontinue features of this free service with reasonable notice where feasible.

7. Liability

We are liable without limitation for intent (Vorsatz) and gross negligence (grobe Fahrlässigkeit), for injury to life, body, or health, and under the German Product Liability Act. For slight negligence, we are liable only for breach of essential contractual obligations (Kardinalpflichten) — obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose fulfilment you may regularly rely — and then only up to the damage typical and foreseeable for a free service of this kind. Any further liability is excluded. This does not shift the burden of proof to your disadvantage and does not limit any mandatory statutory rights you have as a consumer.

8. Governing law and jurisdiction

These terms are governed by German law, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer resident in the EU, the mandatory consumer-protection provisions of your country of residence remain unaffected. Place of jurisdiction for merchants is Munich, Germany.

9. Final provisions

We may amend these terms for the future (for example, when features change); the current version is always published at this address, and material changes to an account-based service will be announced in the app. If a provision of these terms is or becomes invalid, the remaining provisions remain unaffected.
