Terms of Service

1. Eligibility

You must be at least 18 years old to use Tensor.chat. By registering, you represent and warrant that you are at least 18 years of age. We reserve the right to request proof of age and to terminate accounts that violate this requirement.

2. Service Description

Tensor.chat is an AI chat platform that provides access to various third-party AI language models for conversational purposes. Access is provided through a free plan and optional paid subscription plans (see Sections 9 and 10).

We continuously develop the service and may change, add, or remove features, models, and providers. We may suspend or discontinue the free plan or parts of the service at any time. For paid subscriptions, we will inform you at least 14 days in advance of any material reduction of the service or of its discontinuation; you may then terminate your subscription immediately and receive a pro-rata refund of prepaid fees for the unused period. Statutory rights of consumers remain unaffected.

3. Account Registration and Security

• You must provide truthful, accurate, and complete information during registration and keep it up to date.
• You are solely responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account.
• You must notify us immediately of any unauthorized use of your account.
• You may not create multiple accounts, share your account with third parties, or transfer your account to another person.
• We reserve the right to refuse registration, suspend, or terminate any account at our sole discretion.

4. Acceptable Use

You agree not to use Tensor.chat to:

• Violate any applicable law, regulation, or third-party rights.
• Generate, solicit, or distribute content that is illegal, harmful, threatening, abusive, harassing, defamatory, obscene, or otherwise objectionable.
• Generate content that exploits, harms, or endangers minors.
• Attempt to circumvent rate limits, security measures, access controls, or usage restrictions.
• Reverse-engineer, decompile, disassemble, or attempt to derive the source code of the service.
• Scrape, crawl, or systematically extract data from the service by automated means.
• Impersonate another person, entity, or misrepresent your affiliation.
• Use the service for spam, phishing, social engineering, or distribution of malware.
• Interfere with, disrupt, or place an unreasonable load on the service or its infrastructure.
• Use the service to develop a competing product or service.
• Resell, sublicense, or commercially redistribute access to the service without prior written consent.

Violation of these rules may result in immediate account suspension or permanent termination without prior notice and without refund of any prepaid fees. We reserve the right to report illegal activities to the appropriate authorities.

5. AI-Generated Content — No Warranties

You expressly acknowledge and agree that:

• AI responses are generated by third-party language models and may be inaccurate, incomplete, misleading, biased, or entirely fabricated ("hallucinations").
• AI responses do not constitute professional, medical, legal, financial, psychological, or any other form of expert advice.
• You must independently verify any information provided by the AI before relying on it, particularly for decisions that could affect health, safety, finances, or legal standing.
• You are solely responsible for any decisions, actions, or consequences arising from your use of or reliance on AI-generated content.
• We do not review, endorse, or guarantee the accuracy, reliability, completeness, or suitability of any AI response.
• Different AI models may produce different responses to the same input. The selection of a model does not imply any particular level of quality or accuracy.

6. User Content

• You retain all rights to the content you submit ("User Content").
• By submitting User Content, you grant us a non-exclusive, worldwide, royalty-free license to process, store, and transmit your content solely for the purpose of providing and improving the service.
• You represent and warrant that you have all necessary rights to submit your User Content and that it does not infringe any third-party rights.
• You are solely responsible for your User Content. We do not monitor or pre-screen content but may remove content that violates these Terms.

7. Intellectual Property

The Tensor.chat platform, including its software, design, branding, features, and documentation, is the intellectual property of the operator and is protected by applicable intellectual property laws. You may not copy, modify, distribute, or create derivative works based on the platform without prior written consent.

8. Third-Party Services

Tensor.chat integrates third-party AI model providers and other services. These providers have their own terms and privacy policies. We are not responsible for the availability, accuracy, or practices of third-party services. Your use of the service constitutes acceptance that your data may be processed by these third parties as described in our Privacy Policy.

9. Free Plan and Credits

• Usage of Tensor.chat is measured in credits. Every plan includes a credit allowance per time window (e.g. per 12 hours) as shown in the app under "Plans & Usage". Credits reflect the cost of the AI models you use; different models consume credits at different rates.
• The free plan is provided free of charge and without any obligation on our part. Its allowance may vary with platform load and region and may be changed or withdrawn at any time.
• Credits are not money, have no cash value, are not transferable, and unused credits expire at the end of each window. Fair use applies: automated or excessive usage patterns that impair the service for others may be throttled.
• We may adjust the credit allowance of a paid plan with at least 30 days' notice by email; if the allowance is materially reduced, you may terminate the subscription immediately with a pro-rata refund for the unused period.

10. Paid Subscriptions and Payment

• Plans and prices. Paid plans (e.g. Starter, Plus, Pro, Ultra) and their monthly prices are shown in the app under "Plans & Usage" and during checkout. Prices are in euros and are final prices; in accordance with § 19 UStG (German small business exemption) no VAT is charged.
• Conclusion of contract. The subscription contract is concluded when you complete the checkout by clicking the order button ("Subscribe" / "Zahlungspflichtig abonnieren"). You will receive a confirmation and an invoice by email. The contract text is not stored by us beyond the invoice; these Terms are available at any time at tensor.chat/terms.html.
• Term and renewal. Subscriptions run for one month and renew automatically for further one-month periods unless cancelled before the end of the current period. You are charged at the beginning of each period.
• Cancellation. You may cancel at any time with effect to the end of the current billing period via "Manage Subscription" in the app (Stripe customer portal), via the "Cancel subscription" page at tensor.chat/cancel.html, or by email. After cancellation your account continues on the paid plan until the end of the paid period and then returns to the free plan. Periods already paid are not refunded, except where these Terms or mandatory law provide otherwise.
• Plan changes. You may switch plans in the customer portal. Upgrades take effect immediately and are charged pro rata; downgrades take effect at the next renewal.
• Payment. Payments are processed by Stripe Payments Europe, Ltd., Dublin, Ireland ("Stripe"). We do not store your full card details. Available payment methods are shown at checkout. By subscribing you authorise us and Stripe to charge the recurring fee to your chosen payment method.
• Failed payments. If a renewal payment fails, Stripe will notify you and retry. If payment cannot be collected within a few days, the subscription is cancelled and your account returns to the free plan; you may subscribe again at any time.
• Price changes. We may change subscription prices with at least 30 days' notice by email. Price changes apply from the next renewal after the notice period. If you do not agree, you may cancel before the change takes effect; continued use after that date constitutes acceptance.
• Invoices. Invoices and receipts are provided electronically by email and in the customer portal.

11. Right of Withdrawal for Consumers (Widerrufsrecht)

If you are a consumer (a natural person acting for purposes outside your trade, business or profession), you have the following right of withdrawal:

Because the subscription starts immediately after checkout at your express request, you acknowledge that in case of withdrawal you owe a pro-rata amount for the period in which the service was available to you.

12. Warranty for Paid Services

For paid subscriptions, the statutory warranty rights for digital services (§§ 327 et seq. BGB for consumers) apply. We provide the service with reasonable skill and care, but — given its dependence on third-party AI providers — we do not guarantee uninterrupted availability or that any particular model remains available. Section 5 (AI-generated content) applies to paid plans as well. The free plan is provided without warranty to the extent permitted by law.

13. Limitation of Liability

• We are liable without limitation for damages caused intentionally or by gross negligence, for injury to life, body or health, under the German Product Liability Act, and where we have given a guarantee.
• In cases of slight negligence we are liable only for the breach of essential contractual obligations (obligations whose fulfilment is a prerequisite for the proper performance of the contract and on whose observance you may regularly rely), and in that case only for the typical, foreseeable damage.
• Any further liability is excluded. This applies in particular to damages resulting from reliance on AI-generated content (see Section 5), from the unavailability of individual AI models or third-party providers, and from loss of data that you could reasonably have backed up yourself.
• For the free plan, which is provided free of charge, our liability is additionally limited to intent and gross negligence in accordance with §§ 521, 599 BGB, without prejudice to the first bullet above.
• The above limitations also apply in favour of our employees, agents and vicarious agents.

14. Indemnification

If third parties assert claims against us because of your User Content or because you have culpably violated these Terms or applicable law, you shall indemnify us against such claims, including reasonable costs of legal defence, to the extent you are responsible for the violation. This does not apply where you are not at fault.

15. Account Termination

• Free accounts: we may suspend or terminate free accounts at any time; you may stop using the service at any time.
• Paid subscriptions: both parties may terminate with effect to the end of the current billing period (see Section 10). We may terminate a paid subscription without notice for good cause, in particular for serious or repeated violations of Section 4; in that case prepaid fees for the remaining period are not refunded to the extent permitted by law.
• You may delete all of your chats and data yourself at any time. To delete your entire account, contact us at hig5hleader@gmx.de.
• Upon termination, your right to use the service ceases immediately. Data deletion is handled in accordance with our Privacy Policy.
• Sections 5 (AI Content Disclaimer), 7 (Intellectual Property), 13 (Limitation of Liability), 14 (Indemnification), and 16 (Governing Law) survive termination of these Terms.

16. Governing Law and Dispute Resolution

These Terms are governed by and construed in accordance with the laws of the Federal Republic of Germany, without regard to its conflict of laws provisions. If you are a consumer residing in the EU, you additionally retain the protection of the mandatory provisions of the law of your country of residence.

For disputes arising from these Terms, the courts of Hessen, Germany shall have jurisdiction, unless mandatory consumer protection laws designate a different jurisdiction.

We are neither obligated nor willing to participate in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG).

17. Severability

If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary so that the remaining provisions remain in full force and effect.

18. Entire Agreement and Changes to these Terms

These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the use of Tensor.chat and supersede any prior agreements.

We may amend these Terms for valid reasons (e.g. changes in law, new features, security). Paid subscribers will be informed of material changes by email at least 30 days before they take effect and may object; if you object, either party may terminate the subscription with effect to the end of the current period. Otherwise the amended Terms apply from the stated date.
