General Terms and Conditions

General Terms and Conditions for the use of Lindoza. Last updated: 23.05.2026 (Version 1.1).

Sec. 1 Scope of application, provider

(1) These General Terms and Conditions („GTC“) apply to all contracts between

Benjamin Lison — Lindoza (sole proprietorship)
Am Kohlgarten 10
38442 Wolfsburg, Germany
(hereinafter „provider“, „we“)

and its users (hereinafter „you“, „user“) regarding the online service Lindoza (hereinafter „service“).

(2) The service is aimed at consumers and business users alike. A consumer within the meaning of these GTC is, pursuant to Sec. 13 BGB (German Civil Code), any natural person who enters into a legal transaction for purposes that predominantly can be attributed to neither their commercial nor their independent professional activity.

(3) Deviating terms of the user are not recognized unless we expressly consent to their validity in text form (Sec. 126b BGB).

Sec. 2 Subject matter of the contract — what Lindoza is

(1) Lindoza is an online training toolwith which users conduct spoken conversations with AI-generated role-play personas in order to practice difficult conversations (e. g. job application, conflict, relationship, sales conversations).

(2) The exact scope of services results from the product descriptions on our website and the respectively activated functions in the account.

(3) Important note: Lindoza is

• not a substitute for therapy and not a psychotherapeutic, psychiatric or medical service;
• not coaching and not occupation-related counseling within the meaning of the counseling-accreditation regulations;
• not legal advice or tax advice;
• not marriage, family or parenting counseling.

Lindoza serves exclusively for independent reflection and for practicing conversation skills. In the case of psychological strain, crisis situations or suicidal thoughts, please contact professional help immediately:

• Telephone counseling (Telefonseelsorge): 0800-111 0 111 or 0800-111 0 222 (24/7, free of charge)
• In acute emergencies: 112

Sec. 3 Conclusion of contract

(1) By registering an account (entering the email address and confirming the magic link) you submit a binding offer to conclude a usage contract. Upon activation of your account we accept this offer.

(2) The use of chargeable functions (voice sessions) takes place by topping up a balance (wallet top-up) via our payment service provider Stripe. With the top-up you conclude a separate chargeable contract regarding the respective balance amount.

(3) The minimum age for use is 18 years. By registering you affirm that you are of legal age. Use by minors is excluded.

Sec. 4 Right of withdrawal for consumers

Note: This withdrawal instruction uses the formal „Sie“ form of address prescribed by law in order to preserve the protective effect of the official model (Annex 1 EGBGB, Introductory Act to the German Civil Code).

Preliminary remark — what can be withdrawn and when

When using Lindoza, legally separate contracts arise, each with its own withdrawal treatment:

• a) Account registration (free of charge). The email address that you provide upon registration we process exclusively in order to fulfil your request for provision of the service (login, authentication, magic-link dispatch, transactional confirmations). This means the exception under Sec. 312 (1a) sentence 2 BGB applies. For the mere account registration there is therefore no statutory right of withdrawal. You can delete the account at any time under Settings → Leave account without giving reasons.
• b) Wallet top-up (for a charge). With every top-up of your balance you conclude an independent chargeable contract regarding the purchase of the respective top-up amount. For this the following statutory 14-day right of withdrawal applies.
• c) First free trial session (max. 10 min). The one-time free trial session is a gratuitous service contract within the meaning of Sec. 327 (2) sentence 2 no. 1 BGB. The right of withdrawal expires pursuant to Sec. 356 (4) no. 1 BGB automatically upon the complete end of the trial session; a separate confirmation on your part is not required for this.
• d) Voice sessions from the wallet balance. These are digital services within the meaning of Sec. 327 (2) sentence 2 no. 1 BGB, which are drawn from the balance acquired under (b). As long as you are still within the 14-day withdrawal period of your last top-up, we obtain before each session start the double confirmation pursuant to Sec. 356 (4) no. 2 BGB (two separate checkboxes). For completely rendered sessions for which you have given this double confirmation, the right of withdrawal expires; unused balance remains refundable.

The following withdrawal instruction relates primarily to the chargeable wallet top-up contract (b).

Withdrawal instruction

Right of withdrawal. You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of conclusion of the contract.

To exercise your right of withdrawal, you must inform us

Benjamin Lison — Lindoza
Am Kohlgarten 10
38442 Wolfsburg, Germany
Email: software@lindoza.com

Note: We do notoffer telephone customer support. Please use the postal route or the stated email address for all concerns — we usually respond within one business day.

of your decision to withdraw from this contract by means of an unequivocal statement (e. g. a letter sent by post or an email). You may use the attached model withdrawal form for this, which is however not mandatory.

To meet the withdrawal deadline, it is sufficient for you to send the notification of the exercise of the right of withdrawal before the withdrawal period expires.

Consequences of withdrawal

If you withdraw from this contract, we shall reimburse you all payments that we have received from you without undue delay and at the latest within fourteen days from the day on which the notification of your withdrawal from this contract has reached us. For this reimbursement we use the same means of payment that you used in the original transaction, unless expressly agreed otherwise with you; in no case will you be charged any fees on account of this reimbursement.

If you have requested that the services should begin during the withdrawal period, then you must pay us a reasonable amount corresponding to the proportion of the services already rendered up to the point in time at which you notify us of the exercise of the right of withdrawal with respect to this contract, compared to the total scope of the services provided for in the contract.

Early expiry of the right of withdrawal (Sec. 356 (4) BGB)

In the case of a contract for the provision of services, your right of withdrawal expires upon the complete provision of the service if we have begun the execution of the service only after you have given your express consent to this and at the same time confirmed your awareness that you lose your right of withdrawal upon complete performance of the contract by us.

Notes on the wallet model

Lindoza voice sessions are digital services within the meaning of Sec. 327 (2) sentence 2 no. 1 BGB. The mere top-up of your wallet balance does not in itself lead to the expiry of the right of withdrawal. The expiry occurs only for those completely rendered voice sessions for which, before the session start, you have both expressly consented to the execution before expiry of the withdrawal period and confirmed the loss of the right of withdrawal upon complete provision (double checkbox in the session-start flow).

In the event of an effective withdrawal, we will refund unused balance without undue delay within fourteen days to the same means of payment.

Model withdrawal form (Annex 2 EGBGB)

If you want to withdraw from the contract, then please fill out this form and send it back.

Sec. 5 Prices & payment

(1) Lindoza is billed via a prepaid wallet model: you purchase balance (in euros), which is consumed per voice session in small increments (pay-per-minute).

(2) The current prices are shown on the website. All prices are understood as final prices including the statutory German value added tax (currently 19 %). On invoices, the value added tax is shown separately.

(3) Payment processing is carried out by our payment service provider Stripe (Stripe Payments Europe Ltd., Ireland). For their payment terms and conditions, the Stripe contractual relationship between you and Stripe applies.

(4) Topped-up balance does not expire. Upon account closure, we refund unused balance on request within 30 days.

Sec. 6 Your obligations as a user

(1) You undertake to:

• provide truthful information upon registration;
• keep your access data secret and not allow unauthorized third parties any access;
• not use the service for unlawful or abusive purposes, in particular not for: harassment, stalking, creation of deepfake audios with an identity reference to real persons, hate speech, spam generation, competitive mimicry of competing services;
• not use any identifiable personal data of third parties without their consent in your persona descriptions. Pseudonyms or initials are sufficient for realistic practice;
• not upload any particularly sensitive content (in particular unlawfully recorded audios of third parties, data of minors);
• use the AI outputs exclusively for your personal reflection and not to use them as a basis for real decisions without further critical examination.

(2) In the event of a breach of these obligations, we reserve the right to temporarily block your account or — in the case of serious or repeated breaches — to terminate for cause. Already topped-up balance in this case remains refundable only insofar as it has not yet been consumed.

Sec. 7 AI outputs — what we do not guarantee

(1) Lindoza uses AI models (LLMs such as Claude, TTS models such as ElevenLabs, STT such as Deepgram). These are to the best of our ability, but not free of errors.

(2) We assume no warranty that:

• AI-generated persona responses are factually correct;
• the AI personas enable realistic behavioral predictions about real persons;
• practicing with Lindoza leads to success in real conversations (job application success, conflict resolution, relationship stability, sales closing);
• the AI outputs are free of bias, prejudice or cultural stereotypes.

(3) When the AI touches on sensitive topics (mental health, suicide, self-harm, domestic violence), it asks you to refer to professional help. It does not replace this help.

Sec. 8 Availability, maintenance

(1) We endeavor to achieve the highest possible availability, but do not guarantee any specific uptime quotas. Maintenance and update work can temporarily interrupt the service.

(2) We reserve the right to change, add or discontinue individual functions at any time, insofar as this is reasonable taking into account the legitimate interests of the user.

Sec. 9 Liability

(1) For damages that we or our vicarious agents have caused intentionally or through gross negligence, as well as for damages arising from injury to life, body or health, we are liable without limitation.

(2) In the case of slight negligence, we are liable only for the breach of essential contractual obligations (so-called cardinal obligations). Liability is in this case limited in amount to the foreseeable damage typical for the contract, at most to the amount that the user has paid to us in the last 12 months, but at least 100 €.

(3) Liability for indirect damages, lost profit or consequential damages due to the following of AI recommendations is excluded, insofar as paragraph (1) does not apply.

(4) Liability for damages caused by force majeure or by failures of third-party providers (hosting, AI provider, payment service provider) is excluded, insofar as we have selected the sub-processors with the diligence of a prudent business person.

(5) The provisions of the German Product Liability Act (ProdHaftG) remain unaffected.

Sec. 10 Data protection

We process personal data exclusively within the framework of the statutory requirements. For details, see Privacy Policy.

Sec. 11 Contract term, termination

(1) The usage contract is concluded for an indefinite period. You can terminate it at any time without giving reasons without notice by deleting your account in the settings or by sending an email to software@lindoza.com.

(2) We can terminate the contract ordinarily with a notice period of 30 days to the end of the month. The right to extraordinary termination for good cause remains unaffected.

(3) Upon the end of the contract, your content (personas, sessions, audio, transcripts) is deleted, insofar as no statutory retention obligations exist (for details, see the Privacy Policy).

Sec. 12 Changes to these GTC

(1) We reserve the right to change these GTC, insofar as this is necessary for legal, technical or economic reasons and the ratio of performance and consideration is not shifted to your disadvantage.

(2) We inform you of changes at least 30 days before they take effect by email. If you do not object within this period, the amended GTC are deemed accepted. We will point out this consequence to you separately in the notification.

Sec. 13 Dispute resolution

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

Note: The EU Online Dispute Resolution (ODR) platform was shut down as of 20 July 2025 pursuant to Regulation (EU) 2024/3228. A reference to it therefore no longer applies.

Sec. 14 AI transparency under the EU AI Act (Art. 50)

Lindoza is an AI-based service. In every voice session you are talking to an artificial intelligence, not to a human. The responses of your persona are generated algorithmically by Anthropic Claude (text generation), ElevenLabs (speech synthesis) and Deepgram (speech recognition).

This notice fulfils the transparency obligation under Art. 50 of Regulation (EU) 2024/1689 (EU AI Act), which is fully applicable to affected providers from 02 August 2026. All synthetically generated audios are recognizable as such.

Sec. 15 Liability for defects of digital services (Sec. 327 et seq. BGB)

(1) Lindoza owes the provision of the service in a quality that, pursuant to Sec. 327d et seq. BGB, is governed by the objective and subjective requirements. This includes in particular the properties assured in the product descriptions, the ordinary suitability for the usual use as well as regular updates that are necessary for the maintenance of contract conformity (Sec. 327f BGB).

(2) In the case of defectiveness, you as a consumer have the statutory rights pursuant to Sec. 327i et seq. BGB: supplementary performance (elimination of the defect), upon its failure termination of the contract or price reduction as well as, where applicable, compensation for damages and reimbursement of expenses in accordance with Sec. 9 of these GTC.

(3) Please direct notices of defects informally to software@lindoza.com. We confirm receipt within 5 business days.

Sec. 16 Final provisions

(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers with their habitual residence in another EU member state, mandatory provisions of the consumer protection law there remain unaffected.

(2) For consumers, the statutory places of jurisdiction apply (in particular Sec. 29c ZPO, German Code of Civil Procedure — consumer's place of residence). For merchants, legal entities under public law and special funds under public law the place of performance and exclusive place of jurisdiction for all disputes arising from this contract is Wolfsburg.

(3) Should individual provisions of these GTC be or become invalid, the validity of the remaining provisions remains unaffected. In place of the invalid provision, the statutory regulation applies.

Last updated: 23.05.2026 (Version 1.1). These GTC apply from the day of publication.
