Registration and tax details

Registration court: HRA
Registration number: 116032
VAT identification number: DE353601308

These Terms and Conditions govern the provision and business use of the web-based Perstivo platform. They apply exclusively to entrepreneurs within the meaning of section 14 of the German Civil Code (BGB), legal entities under private or public law and special funds under public law. We do not enter into contracts with consumers within the meaning of section 13 BGB.

The “Customer” is the organisation identified during registration. The person registering confirms that they act for that organisation and are authorised to enter into the contract. Invited members do not themselves become contracting parties. Individually negotiated agreements and offers take precedence over these Terms.

2. Contract formation and organisation account

The presentation of Perstivo on the website does not constitute a binding offer. During self-service signup, the Customer first verifies its business email address. By subsequently submitting the registration and accepting these Terms, the Customer makes a binding offer to enter into the service contract. We accept that offer by activating the organisation and providing access.

Before submitting the registration, the Customer can review and correct its entries. The version of these Terms applicable when the contract is formed can be accessed and saved from the website. Individually agreed Enterprise services are contracted in accordance with the relevant offer.

Information provided during registration and use must be complete and accurate. The Customer must inform us without undue delay of changes to the organisation, representative authority or contact address.

3. Services

Perstivo is a platform for practising workplace conversations. Depending on the agreed service scope, it includes in particular:

• setup and administration of an organisation account;
• inviting and managing members and administrators;
• creating, managing and using training scenarios;
• voice conversations with an AI-generated counterpart;
• transcripts, training feedback and evaluations;
• display of prices, usage and available prepaid balance.

The plan selected when the contract is formed or subsequently agreed individually, together with the features enabled in the application, determines the service scope. The Customer has no entitlement to features that have not been agreed or have only been announced.

4. AI-assisted voice training

The simulated counterpart, transcripts, feedback and scores are generated wholly or partly by AI systems. AI output may be incomplete, inaccurate, biased or generated in a similar form for other users. We therefore do not promise a particular training outcome and do not warrant that output is professionally correct or suitable for a particular case.

Perstivo is intended for practice and reflection. It is not a substitute for legal, human resources, medical, psychological or other professional advice and must not be used as the sole basis for employment decisions or other decisions producing legal or similarly significant effects. Results must be reviewed and placed in context by an appropriately qualified person.

During training, speech is transmitted to the AI service provider configured by us for the organisation. Processing is additionally governed by the Privacy Notice and, where the Customer is the controller, the applicable data processing agreement.

5. Administrators, members and credentials

The Customer appoints at least one organisation administrator. Administrators may invite members, assign roles, manage scenarios, fund the balance and take other binding actions for the organisation. The Customer is responsible for assigning these permissions only to suitable and authorised persons and for disabling access that is no longer required without undue delay.

Credentials are personal and must be kept confidential. Accounts must not be shared by several individuals. Administrator accounts must use the security measures provided by Perstivo, in particular multi-factor authentication. Suspected misuse or loss of credentials must be reported to us without undue delay.

The Customer must ensure that all users it invites comply with these Terms and the usage and security instructions displayed in the application.

6. Permitted use and Customer responsibilities

Perstivo may be used only for lawful business training. In particular, the following are prohibited:

• unlawful, discriminatory or threatening content or use, or content or use that infringes third-party rights;
• entering real names, confidential information or special categories of personal data without the necessary authority and legal basis;
• attempting to circumvent or manipulate security features, access controls, usage metering or charging;
• automated bulk access, disruption, malicious code or loads exceeding the normal contractual purpose;
• reverse engineering or copying the platform except where mandatorily permitted by law;
• using training results as an unreviewed performance, suitability or disciplinary instrument.

The Customer provides the technical requirements for use, including a current browser, suitable internet connection and the required microphone permission. The Customer is responsible for employment, co-determination, data protection and other internal organisational requirements relating to its use of Perstivo.

7. Content and usage rights

Rights in the platform, software, design and content provided by us remain with us or our licensors. For the contract term, the Customer receives a non-exclusive, non-transferable and non-sublicensable right to use Perstivo for its own business purposes within the agreed scope.

Rights in scenarios and other content submitted by the Customer remain with the Customer. For the contract term, the Customer grants us the rights required to store, technically process, transmit to contracted service providers and display that content in accordance with the contract. The Customer warrants that it holds the necessary rights and that the content may lawfully be processed.

If third parties assert claims against us due to culpably unlawful Customer content or use in breach of contract, the Customer will indemnify us against justified claims and reasonable legal defence costs. We will inform the Customer without undue delay and give it a reasonable opportunity to participate in the defence.

8. Prices, prepaid balance and usage metering

Perstivo is offered exclusively in euros on a prepaid basis. The prices displayed to the Customer when the contract is formed or agreed individually apply. Unless expressly identified as gross prices, prices are exclusive of applicable VAT.

Usage-based charges are calculated separately for the participant’s active speaking time and active listening time during the AI response. Partial minutes are charged proportionally based on technically measured usage. A plan may additionally include a monthly base fee. This is also paid exclusively from the prepaid balance; post-paid use on credit is not intended.

Before or during a chargeable action, we may temporarily reserve a reasonable amount from the balance. When the action is complete, the reservation is reconciled against the usage actually measured and any unused remainder is released. If the available balance is insufficient or a reversed payment remains outstanding, chargeable features may not be used until the balance is funded or the outstanding amount is settled.

Price changes do not apply retrospectively. A different plan becomes effective for the Customer only at the individually agreed or notified time and only for future use. Where a change has not already been individually agreed and is not solely to the Customer’s benefit, the Customer will have a special right to terminate before the change takes effect.

9. Funding and payment processing

Organisation administrators can fund the balance within the displayed minimum and maximum amounts through an enabled payment provider. The amount is credited only after the payment provider has confirmed the payment to our server. A redirect back to Perstivo alone does not constitute payment confirmation.

The terms of the selected payment provider additionally apply to the external checkout. If a payment is refunded, reversed or charged back, an earlier credit is adjusted accordingly. Any resulting negative balance must be settled by the Customer without undue delay. The balance does not earn interest and is not converted into another currency.

Paid-in, unused balance does not expire while the contract remains in force. It is paid out during the contract term only where required by law or where we agree to a refund. Refunds may be made through the original payment method.

10. Availability, maintenance and service changes

We provide Perstivo with the level of care customary for comparable online services. A particular availability or response time is owed only where expressly agreed in an offer or service level agreement. Temporary restrictions may arise in particular from maintenance, security updates, disruption affecting telecommunications, hosting, AI or payment providers, or events outside our reasonable control.

Where possible, we announce planned maintenance in advance. We may make technical adjustments and reasonable improvements provided the agreed core functions remain available. If an agreed service is materially changed to the Customer’s detriment, we will inform the Customer in advance and provide a reasonable special right to terminate.

11. Privacy and confidentiality

Information about our processing of personal data is provided in the Privacy Notice. Where the Customer processes personal data for which it is the controller through Perstivo, the parties will enter into any required data processing agreement before that processing begins. The Customer remains responsible for the legal basis, transparency towards data subjects, internal permissions and any required involvement of employee representative bodies.

Each party must treat the other party’s non-public business, technical and organisational information as confidential and use it only to perform the contract. Mandatory disclosure obligations remain unaffected.

12. Defects and support

The Customer must report reproducible issues with a description that is as precise as reasonably possible. We will remedy material defects for which we are responsible within a reasonable period. We must first be given an opportunity to cure. If the cure fails, the Customer has the statutory remedies.

There is no defect to the extent a restriction results from use contrary to the contract, unsuitable Customer technology, Customer content or a circumstance outside our responsibility. The typical characteristics of generative AI described in section 4 do not by themselves constitute a defect.

13. Liability

We have unlimited liability for intent and gross negligence, culpable injury to life, body or health, under the German Product Liability Act, and to the extent of an express guarantee or fraudulent concealment of a defect.

In the event of a slightly negligent breach of a material contractual obligation, our liability is limited to the loss that was foreseeable and typical for the contract when it was formed. Material contractual obligations are obligations whose performance is essential to the proper performance of the contract and on which the Customer can normally rely. Liability for other cases of slight negligence is excluded.

These limitations also apply for the benefit of our legal representatives, employees and agents. Mandatory statutory liability remains unaffected.

14. Suspension

We may temporarily suspend accounts or individual features where there is specific evidence of a security incident, unlawful or material use in breach of contract, a legal obligation requires suspension, or due amounts or payment reversals remain unsettled. We will consider the Customer’s legitimate interests, limit the measure where possible and inform the Customer in advance or without undue delay afterwards. The right to terminate for cause remains unaffected.

15. Term and termination

The self-service contract is entered into for an indefinite term. The Customer may terminate it in text form at any time with effect at the end of the current month. We may terminate it on 30 days’ notice to the end of a month. Different terms and notice periods in an individual offer take precedence.

Either party may terminate for cause. Where the reason can be remedied, a reasonable period to remedy must generally be set first. The Customer may send a termination notice to kontakt@greck-consulting.de.

Access ends when the contract terminates. Active reservations and open payment transactions are finally reconciled. Any remaining balance actually paid in is then refunded after verification through the original payment method or an agreed bank account; bonus or goodwill credit is not paid out. Outstanding claims may be offset.

The Customer is responsible for securing content and results it requires before the contract ends, to the extent the application provides a corresponding output. Afterwards, data is deleted or retained in restricted form in accordance with legal requirements, the Privacy Notice and any applicable data processing agreement.

16. Changes to these Terms

Changes to these Terms for an existing contract require agreement between the parties. We may correct purely editorial clarifications that do not alter the Customer’s rights or obligations in the published version. The version displayed when a new contract is formed applies to that contract.

17. Final provisions

The laws of the Federal Republic of Germany apply, excluding the United Nations Convention on Contracts for the International Sale of Goods. To the extent legally permitted, the exclusive place of jurisdiction is the Provider’s registered office. The place of performance is also the Provider’s registered office.

If a provision of these Terms is or becomes wholly or partly invalid, the remaining provisions remain effective. The invalid provision is replaced by the applicable statutory rules.

This English version is a translation. In the event of inconsistencies, the German version prevails unless expressly agreed otherwise.
