Terms of Service

Quantarah — quantarah.com
Version: 24 September 2026

This English translation is provided for convenience. In the event of any discrepancy, the German version ("Allgemeine Geschäftsbedingungen", quantarah.com/de/agb) prevails.

§ 1 Provider and Scope

(1) These Terms govern all contracts for the use of the "Quantarah" service (the "Service") between Pascal Ali – Quantum Drift, sole proprietor, Gerlandweg 39, 4060 Leonding, Austria, e-mail: support@quantarah.com, Austrian business register (GISA) no. 40088334, member of the Austrian Economic Chamber (WKO) Upper Austria (the "Provider"), and consumers within the meaning of § 1 of the Austrian Consumer Protection Act (KSchG) (the "User").

(2) The Service is intended exclusively for adults (18 years or older).

(3) Deviating or supplementary terms of the User do not become part of the contract.

§ 2 Description of Services

(1) Quantarah provides access to entertainment chats with "Tara", a fully synthetic, artificially created AI persona (an AI system). Tara is not a real person. All replies and images are generated by artificial intelligence and are labelled as such.

(2) The chat takes place via the Telegram messenger. A Telegram account is required; Telegram's own terms apply to that platform.

(3) The following plans are available; message and image quotas are upper limits ("up to") and are owed in the amount shown on the pricing page (quantarah.com/pricing) at the time the contract is concluded:

• Free: free of charge, with limited message and image quotas;
• Plus: €9.99 per month;
• Premium: €24.99 per month.

(4) The Service is provided for entertainment purposes only. It does not provide medical, psychological, therapeutic, legal, financial or any other advice. AI-generated replies may be factually incorrect; no accuracy of outputs is warranted. In a personal crisis, please contact professional help services (e.g. Telefonseelsorge Austria 142; in an emergency call 112 or ambulance 144; outside Austria your local emergency services).

(5) The Service is aimed at adults; pornographic content is not part of the Service.

(6) The Free plan is a free offering without a subscription. The Provider may adjust or discontinue the Free plan with reasonable advance notice; there is no entitlement to its continuation. Ongoing paid subscriptions remain unaffected.

§ 3 Conclusion of Contract

(1) A contract for a paid plan is concluded when the User completes the order process on the website by clicking the order button indicating an obligation to pay and the payment is successfully authorised. The presentation of plans on the website does not constitute a binding offer by the Provider.

(2) Inputs can be corrected at any time before the order is submitted; the checkout page summarises plan, price and term before completion.

(3) Immediately after conclusion of the contract, and in any case before activation of access, the User receives a contract confirmation by e-mail to the address provided during checkout. It contains the essential contract data, these Terms, the withdrawal policy and the model withdrawal form. The current version of these Terms is available at quantarah.com/en/terms; the User is asked to save the confirmation.

(4) The contract languages are German and English. In the event of discrepancies between the language versions, the German version prevails.

(5) Payments are processed by the payment provider Stripe. Available payment methods are shown during checkout.

(6) Conclusion of the contract requires the User's confirmation of being at least 18 years old.

§ 4 Prices and Payment

(1) All prices are final prices. The Provider is a small business within the meaning of § 6 (1) no. 27 of the Austrian VAT Act (UStG); the supplies are VAT-exempt and no VAT is therefore shown.

(2) The fee for the selected plan is charged monthly in advance via the selected payment method. The total cost per billing period (one month) equals the monthly price of the selected plan.

§ 5 Term and Termination

(1) The subscription has a term of one month and renews for successive one-month periods unless cancelled.

(2) The User may cancel the subscription at any time with effect from the end of the current billing period, without giving reasons and without any formal requirements:

• via the customer portal of the payment provider Stripe (link in the contract confirmation and at quantarah.com/en/subscription), or
• informally by e-mail to support@quantarah.com.

(3) The Service remains available until the end of the billing period already paid for; the fee for the current period is not refunded in the case of ordinary cancellation.

(4) The right of both parties to extraordinary termination for good cause remains unaffected.

§ 6 Right of Withdrawal

(1) Consumers have a 14-day right of withdrawal under the Austrian Distance and Off-Premises Transactions Act (FAGG). The details, legal consequences and the model withdrawal form are set out in the withdrawal policy, available at quantarah.com/en/withdrawal and provided with the contract confirmation.

(2) Performance begins before the end of the withdrawal period only if the User expressly requests this during checkout. If the User then withdraws from the contract, the User must pay a proportionate amount for the service provided up to the withdrawal (§ 16 FAGG); details are set out in the withdrawal policy.

§ 7 Availability and Warranty

(1) The Provider aims for high availability of the Service. Uninterrupted availability is not owed; short-term impairments may result in particular from maintenance and further development, from disruptions of third-party services used (in particular Telegram, payment and AI infrastructure) or from events beyond the Provider's control. Maintenance is scheduled during low-usage times where possible.

(2) Statutory warranty law applies, in particular the Austrian Consumer Warranty Act (VGG). During the contract term, the Provider supplies those updates that are necessary for the Service to remain in conformity with the contract.

(3) Faults and defects may be reported informally to support@quantarah.com.

§ 8 Liability

(1) The Provider is liable without limitation for damage resulting from injury to life, body or health, and for damage caused by intent or gross negligence.

(2) The Provider is not liable for other damage caused by slight negligence.

(3) Mandatory statutory liability provisions, in particular under the Austrian Product Liability Act, remain unaffected.

§ 9 AI Transparency and Rights in Generated Content

(1) The User interacts with an AI system. This is disclosed on the website, at the start of the chat and in this contract (Art. 50 of Regulation (EU) 2024/1689 — the "AI Act").

(2) Images sent by Tara are AI-generated and labelled as such. The depicted persona is entirely fictional; any resemblance to real persons would be coincidental and unintended.

(3) The User receives a simple, non-exclusive, non-transferable right to use the images generated for them for private, non-commercial purposes. It is prohibited in particular to remove AI labels, to present the images as photographs of real persons, or to use them to deceive third parties.

§ 10 User Obligations; Suspension

(1) The User must not

1. use the Service for unlawful content or purposes;
2. circumvent or attempt to circumvent the Service's safety and protection mechanisms;
3. attack, overload or make automated mass use of the Service's infrastructure;
4. pass on access to third parties;
5. use the Service as a minor.

(2) In the event of violations, the Provider may temporarily suspend access after a prior warning or terminate the contract for good cause without notice; no warning is required where it is unreasonable for the Provider due to the severity of the violation.

(3) If the Provider terminates for good cause without notice, prepaid fees for the period no longer usable are refunded proportionately. Further statutory claims of the Provider (in particular for damages) remain unaffected.

§ 11 Changes to the Service, Prices and these Terms

(1) The Provider may make minor, objectively justified changes to the Service that are reasonable for the User (for example replacing or updating the AI models used, increasing quotas, adjustments required for safety or legal reasons), provided the main contractual obligations are not materially restricted.

(2) Price changes apply only to newly concluded contracts. For an existing subscription, the price changes only if the Provider offers the change to the User by e-mail in good time before it takes effect and the User expressly consents. If the User does not consent, the subscription continues at the previous price until the end of the current billing period and then ends without notice being required.

(3) Changes to these Terms apply to newly concluded contracts from their publication. For existing subscriptions, changes apply only with the User's express consent; otherwise the previous version continues to apply.

§ 12 Data Protection

Information on the processing of personal data is provided in the privacy policy at quantarah.com/en/privacy.

§ 13 Dispute Resolution

The Provider is neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board. Complaints may be addressed directly to support@quantarah.com; the Provider will endeavour to find an amicable solution.

§ 14 Final Provisions

(1) Austrian law applies, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. If the User is a consumer habitually resident in another state, the mandatory consumer protection provisions of that state remain unaffected.

(2) The statutory places of jurisdiction apply; the protective provision of § 14 KSchG remains unaffected.
