Public offer

Contract for the provision of services for a fee · Version 1.1 · effective from 25 August 2026

Legal force. Only the Russian version of this document has legal effect. This translation is provided for convenience; if the two differ in any way, the Russian original governs — read the original. The service is operated under the law of the Russian Federation, and the Russian text is the one a court, a regulator and the parties rely on.

Before taking payment: the owner of the service, together with a lawyer, must fill in, in section 11, the full name of the company or the sole trader’s full name, the tax and registration numbers, the address and a working email address; and in clause 3.4, the tax regime applied and how VAT is charged. These details are not in the repository, so they have deliberately not been filled in. Until section 11 is completed, this offer is not a contract that can be concluded.

1. General provisions

1.1. This document is a public offer within the meaning of article 435 and clause 2 of article 437 of the Civil Code of the Russian Federation and sets out the terms on which the “Kristina AI” service, published at kristina-ai.ru, is provided.

1.2. The person providing the services (the “Provider”) is identified in section 11.

1.3. The Customer under this contract is the legal entity or sole trader in whose name a company has been created in the service. The user who registers the company confirms that they are authorised to act on its behalf.

1.4. The offer is accepted — that is, its terms are accepted fully and unconditionally — by paying for the chosen plan (clause 3 of article 438 of the Civil Code). The contract is concluded when the payment is received.

1.5. By paying for a plan the Customer confirms that it has read this offer, the Terms of service and the Personal data processing policy, and accepts them. The Terms of service form an integral part of this contract.

2. Subject of the contract

2.1. The Provider gives the Customer access to the features of the “Kristina AI” service to the extent corresponding to the plan paid for.

2.2. The service receives incoming enquiries from the Customer’s customers through the connected channels, forms answers on the basis of the knowledge base uploaded by the Customer, collects enquiries and passes them to the Customer’s managers and to the connected external systems.

2.3. The service is not a telecommunications operator, is not a customer relationship management (CRM) system and does not replace anything that requires a licence.

2.4. Answers are generated by a language model and may contain errors. The Customer chooses the answer moderation mode, fills the knowledge base and configures the scenarios itself; how responsibility for this is allocated is set out in section 9 and in the Terms of service.

3. Plans

3.1. The plans in force:

3.2. Prices are stated in Russian roubles and are a fixed fee for the billing period: no commission on enquiries and no charge per message are levied.

3.3. The limits of a plan are its ceiling, not a guideline. Once the monthly limit of AI answers is exhausted, the Provider’s obligation to generate such answers in the current period ends; enquiries continue to be received and passed to the Customer. The Customer may move to a plan with higher limits at any time.

3.4. To be completed before publication: the tax regime applied by the Provider and how VAT is charged.

3.5. The Provider may change its prices. A change does not affect a period already paid for.

4. Trial period

4.1. The trial period is granted once, lasts 14 calendar days and requires no bank card.

4.2. The trial period starts when the email address of the company’s first manager is confirmed, not at registration.

4.3. The trial period is provided with no guarantee that it will continue to exist: the Provider may change its terms or stop offering it to new Customers at any time. Such a change does not affect a trial period already begun.

5. Payment

5.1. Payment is made by bank card through the YooKassa payment service. The Provider does not receive or store bank card details — those are handled by the payment service.

5.2. Access to the plan paid for is activated once the payment service confirms the payment. Until that confirmation is received the payment is treated as incomplete and the plan as not activated.

5.3. The fiscal receipt required by Federal Law No. 54-FZ is generated by the payment service’s online cash register and sent to the manager’s email address recorded in the account area.

5.4. If online card payment is unavailable, a plan can be activated against an invoice: the Provider issues the invoice, and the plan and the access period are assigned once payment is received.

5.5. Paying for a plan includes automatic renewal by default. The payment method is stored by the payment service, and at the end of the period paid for the charge for the next period is taken without further confirmation from the Customer.

5.6. Automatic renewal can be switched off in the account area in one step and at any time. Switching it off does not end access: the company continues to use the service until the end of the period already paid for, after which access to the paid features ends. It can be switched back on in the same place.

5.7. If the charge for the next period fails, the Provider notifies the Customer and may retry. If payment has not been made by the end of the period paid for, access to the paid features is suspended.

6. When the service is treated as provided

6.1. The service is treated as duly provided and accepted at the end of the access period paid for, whether or not the limit of AI answers was actually exhausted and however much the service was used.

6.2. Unused AI answers and other limits do not carry over to the next period, are not compensated and have no monetary value.

7. Refunds

7.1. If a payment went through but access was not activated, or if the features paid for do not work for reasons attributable to the Provider, the Provider refunds the amount paid in full or fixes the fault, at the Customer’s choice.

7.2. If the Customer withdraws from the contract before the end of the period paid for, the cost of the unused part of the period is refundable, less the expenses actually incurred by the Provider, including the cost of processing the payment charged by the payment service.

7.3. A refund request is sent to the contact details given in section 11, from the email address of the company’s manager, stating the date and the amount of the payment. It is considered within 10 calendar days. The refund is made by the same means as the payment.

8. Data about the Customer’s customers

8.1. In respect of the personal data of the Customer’s visitors and customers that reaches the service through the connected channels, the Customer is the person determining the purposes of processing, and the Provider processes that data on the Customer’s instructions (part 3 of article 6 of Federal Law No. 152-FZ).

8.2. The Customer ensures that there are lawful grounds for transferring such data to the service, including obtaining the necessary consents from its customers and notifying them about the processing.

8.3. The Provider does not use the Customer’s customers’ data for its own purposes and does not pass it on for the training of artificial intelligence models.

8.4. The specific terms of the instruction to process personal data and the allocation of roles between the parties are recorded in a separate agreement or addendum. How data is processed on the Provider’s side is described in the Personal data processing policy.

9. Warranties and liability

9.1. The service is provided “AS IS” and “AS AVAILABLE”.

9.2. The Provider gives no warranties that are not expressly stated in this contract, including any warranty that the service is fit for the Customer’s particular purposes, meets its expectations, or runs without interruption or error, or that the Customer will achieve any commercial result.

9.3. The Provider does not warrant the accuracy, completeness or appropriateness of answers generated by the language model, nor that the customer’s intent will always be recognised correctly. That is what the moderation modes are for, and choosing the mode is the Customer’s decision.

9.4. No service level agreement (SLA) has been concluded between the parties; availability targets may be agreed in a separate written agreement. The Provider is not responsible for interruptions caused by failures of third-party suppliers — language model providers, the payment service, messengers and classifieds platforms, online booking and CRM systems, telecommunications operators and providers of computing infrastructure — or by scheduled maintenance of the service.

9.5. The Provider’s aggregate liability under this contract is limited to the amount actually paid by the Customer for the last period paid for (articles 15 and 400 of the Civil Code of the Russian Federation). If no payment has been made, liability is limited to the cost of one month of the cheapest paid plan in force on the date of the breach.

9.6. The Provider does not compensate lost profit, indirect losses, loss of commercial opportunity or harm to the Customer’s business reputation, and is not responsible for decisions taken by the Customer or its customers on the basis of the service’s answers, for the content of the Customer’s knowledge base and scenarios, or for the consequences of the Customer choosing a mode in which answers are sent without human review.

9.7. A party is not liable for failure to perform, or improper performance of, an obligation caused by force majeure (clause 3 of article 401 of the Civil Code). The party affected notifies the other within a reasonable time.

9.8. The Customer’s representations as to circumstances, and its duty to compensate the Provider’s property losses, are set by section 11 of the Terms of service.

9.9. The Customer confirms that it is acquiring the services for purposes connected with carrying on business activity and that consumer protection legislation does not apply to the relations between the parties. If the services are in fact acquired for personal, family or household needs, the mandatory rules established in favour of a consumer take precedence over the provisions of this section.

9.10. The limits set by this section do not apply: to liability for an intentional breach of an obligation — an agreement made in advance to exclude or limit such liability is void (clause 4 of article 401 of the Civil Code); to liability for harm to life and health; or to the parties’ duties under personal data legislation and to the rights of data subjects, which cannot be limited by agreement between the parties.

10. Term, changes and dispute resolution

10.1. The offer is in force from publication until it is withdrawn by the Provider. Withdrawal does not terminate contracts already concluded.

10.2. The current revision is always published at this address. The revision in force on the date of payment applies to the period already paid for.

10.3. The relations between the parties are governed by the law of the Russian Federation.

10.4. Before going to court the parties take steps to settle the matter between themselves. A claim is sent to the contact details in section 11 and is considered within 30 calendar days. Disputes not settled out of court are heard by a court under the rules of jurisdiction established by law.

10.5. If an individual provision of the contract is invalid or unenforceable, the remaining provisions are unaffected: the parties proceed on the basis that the contract would have been concluded without that provision.

11. The Provider’s details

Mandatory before publication: the full name of the company or the sole trader’s full name, the tax number (INN), the registration number (OGRN or OGRNIP), the registered and postal address, a working email address for claims and refund requests, and bank details for payment against an invoice.

The same details must be published on the “Contacts” page, in section 10 of the Personal data processing policy and in section 1 of the Consent to the processing of personal data. Do not insert invented details: an unfilled template is more honest and safer.
