1. General Provisions

1.1. This document constitutes a public offer by an individual applying the special tax regime “Tax on Professional Income” (hereinafter, the Operator), addressed to legal entities, and contains all essential terms of the agreement for the provision of services granting corporate access to an information service.

1.2. The Operator’s details (taxpayer identification number and contact details) are specified in the issued invoice or provided upon request.

1.3. Pursuant to Article 437 of the Civil Code of the Russian Federation, this document is recognized as a public offer.

1.4. Acceptance of this offer is payment of the invoice, issued by the Operator. From the moment the funds are credited to the Operator’s account, the agreement is deemed concluded on the terms of this offer as in force on the payment date and with the package parameters (number of licenses, size of the query pool, price) specified in the invoice.

1.5. The person who accepts the offer (hereinafter, the Customer) confirms that they have read this offer, understand its contents, and unconditionally accept all of its terms.

2. Definitions

2.1. Service — the CasusLegal informational case-law search service.

2.2. Connector — a software module (MCP connector) enabling access to the Service from AI assistants. The Operator provides four connectors: “Higher Courts” (Constitutional Court·Supreme Court·Supreme Commercial Court, https://mcp.casus.legal/mcp), “IP Court” (Intellectual Property Court, https://sip.casus.legal/mcp), “Administrative Cases” (Judicial Chamber for Administrative Cases of the Supreme Court of the Russian Federation, https://kas.casus.legal/mcp), “Criminal Cases” (Judicial Chamber for Criminal Cases of the Supreme Court of the Russian Federation, https://kud.casus.legal/mcp). The composition of the connectors included in the Customer’s corporate package is determined by the invoice; the “Higher Courts” connector is always included in the package.

2.3. License (seat) — the right of one Customer employee to use all connectors included in the purchased package during the package period. The number of licenses is specified in the invoice.

2.4. Team query pool — the aggregate limit on requests to the Service through the web chat and Telegram bot, shared by the package licenses permitted to use the pool. At the Customer’s option, access to the pool may be enabled for fewer than all package licenses: the number of licenses with pool access is specified in the invoice; licenses without pool access retain unlimited access to the package connectors. The pool volume is specified in the invoice. Access to the connectors through Supported Assistants (clause 2.6) is not included in the pool and is unlimited.

2.5. Package period — 30 (thirty) calendar days from the activation of access.

2.6. Supported Assistants — Claude (Anthropic), ChatGPT (OpenAI), Grok (xAI), and Hermes (Nous Research).

3. Subject Matter of the Agreement

3.1. The Operator provides the Customer, for a fee, with a corporate package comprising:

a) unlimited access to the Service’s connectors included in the package in accordance with the invoice (from among those specified in clause 2.2), for each license during the package period;

b) a team query pool in the web chat and Telegram bot, shared by all package licenses.

3.2. Unlimited access to the connectors means that there is no limit on the number of requests to the Service through Supported Assistants when used in good faith. The web chat and bot team pool is limited to the volume specified in the invoice.

3.3. The Operator ensures that the connectors operate when connected to Supported Assistants (Claude, ChatGPT, Grok, Hermes). Operation in other AI assistants, clients, or environments is not guaranteed.

3.4. The Service provides exclusively informational access to processed information about judicial acts. The results do not constitute legal advice, a legal opinion, or professional advice.

3.5. Assessing the applicability of the judicial acts found to a specific situation is solely within the competence and responsibility of the Customer and its employees.

4. Price and payment procedure

4.1. The price of the corporate package for the period (30 days) is determined by the invoice issued by the Operator and consists of the price of the named licenses (depending on their number and the set of connectors included in the package) and the price of the team query pool (depending on its volume). Current prices and the package calculator are published at www.casus.legal/corporate.html; the agreed package configuration and final amount are set out in the invoice. The rate for a pool request depends on the pool size and applies to the pool as a whole; if the volume specified by the Customer falls between pricing tiers, it is automatically increased to the nearest tier whose price does not exceed the price of the requested volume (the Customer receives a larger volume at no additional cost; the final volume and amount are set out in the invoice).

4.2. Payment is made by a legal entity against the invoice issued. The Operator applies the special tax regime “Tax on Professional Income”; when payment is received from a legal entity, the rate is 6%. The Operator generates a self-employed tax receipt through the “My Tax” application.

4.3. Payment is made in the amount of 100% of the price before access is provided. No automatic renewal or periodic charges are provided for.

4.4. The Operator may change the price of the services. The change applies to new invoices; a period already paid for is performed under the terms of the paid invoice.

4.5. Prepayment for several periods. At the Customer’s option, an invoice may be issued at once for several package periods (as of the publication date — 1, 6 or 12 periods). The price of each paid period does not change (the invoice amount equals the package price for one period multiplied by the number of paid periods). With prepayment for 6 periods, the Customer is additionally provided with 1 (one) bonus period; with prepayment for 12 periods, 2 (two) bonus periods are provided. During the bonus periods, unlimited access to the package connectors is provided without a team query pool. The package is performed in consecutive periods of 30 calendar days: the team query pool is provided for each paid period in the amount specified in the invoice and expires at the end of the period (Clause 5.3).

5. Term and renewal

5.1. The package remains valid for 30 (thirty) calendar days from the activation of access (issuance of the codes). With prepayment for several periods (Clause 4.5), the package is automatically extended for each subsequent paid period (and then each bonus period) until the period covered by the invoice has been exhausted.

5.2. Upon expiry of the period (or, in the case of prepayment for several periods, upon expiry of the last such period), access is terminated. There is no automatic renewal or automatic charging. Renewal is carried out by issuing and paying a new invoice; the Customer generates the invoice for the next period independently in the personal account (lk.casus.legal/corp), and the package composition may be changed.

5.3. Any unused balance of the team query pool at the time the period expires does not carry over to the next period: the pool is provided for the period and expires at its end. Upon renewal, the pool is provided in the amount specified in the new invoice.

5.4. The certificate of services rendered for the period is generated automatically and sent to the Customer’s email address on the last day of the period; the certificate is available for download at any time in the personal account. The certificate is not a mandatory document for confirming the Customer’s expenses — the payment document is the self-employed tax receipt.

6. Provision of Access

6.1. The Operator provides the Customer with individual access codes — one for each licence — no later than 24 (twenty-four) hours after confirmation that payment has been received. As a rule, the codes are transmitted within several hours after payment.

6.2. Each code enables simultaneous connection to all connectors included in the package according to the invoice. Connector addresses and the connection procedure are set out in Annex No. 1.

6.3. The codes are nominative: each code is intended for use by one specific employee of the Customer. Transferring a code to third parties outside the Customer’s organisation is prohibited.

6.4. The Operator may suspend access in the event of a breach of Section 7 or the terms of Clause 6.3.

7. Rights and Obligations of the Parties

7.1. The Operator undertakes to provide access in accordance with the paid invoice; to take reasonable measures to ensure the operability of the connectors; and to notify the Customer of changes to the offer.

7.2. The Operator does not guarantee: comprehensive coverage of case law; uninterrupted operation; the operability of the connectors in AI assistants that are not Supported; the accuracy and applicability of search results to a particular situation; or the availability and proper operation of Supported assistants and other third-party services.

7.3. The Customer undertakes to: use the Service for lawful purposes; assign codes strictly on a one-code-per-employee basis; not transfer codes outside its organisation; not engage in automated data collection (scraping), bulk downloads or other systematic extraction of data; and not create an abnormal load.

7.4. “Unlimited access” to the connectors (Clause 3.2) means the absence of a quantitative quota when used in good faith personally by the Customer’s employees. The actions listed in Clause 7.3 do not constitute use in good faith. The Operator may apply technical protection measures against automated, mass and other abnormal use — including limiting the frequency and volume of requests and automatically detecting abuse — and may immediately, including automatically and without prior notice, suspend or block access (including access under an individual code) upon detecting such actions. These measures do not apply to ordinary use in good faith and do not breach the condition of unlimited access.

8. Limitation of Liability

8.1. The Service is provided “as is” (as is). The Operator does not undertake any obligations to achieve any particular results for the Customer.

8.2. The Operator is not liable for errors, inaccuracies or AI hallucinations, or for decisions made by the Customer on the basis of the results of the Service.

8.3. The Operator is not liable for interruptions in the operation of Supported assistants (Claude, ChatGPT, Grok, Hermes) or other third-party services.

8.4. The Operator’s aggregate liability on any grounds is limited to the amount actually paid by the Customer for the current period.

9. Refunds

9.1. Since access is provided immediately, the price of the paid period is non-refundable upon the Customer’s unilateral withdrawal, except in the case specified in Clause 9.2.

9.2. A refund of the price, in full or proportionally to the unused time, is made if the Operator failed to ensure the operability of the connectors for more than 72 (seventy-two) consecutive hours for reasons attributable to the Operator, provided that the Customer submits a corresponding request. Unavailability for reasons relating to Supported assistants and other third-party services does not constitute grounds for a refund.

10. Termination and suspension of access

10.1. At the Customer’s initiative: the Customer may discontinue further use of the package at any time. Refunds are governed by Section 9.

10.2. At the Operator’s initiative: the Operator may suspend or terminate access if the Customer breaches Clause 6.3 or Section 7. In the event of termination on this ground, amounts paid are not refunded.

11. Personal data

11.1. By paying the invoice, the Customer confirms that its employees to whom access codes will be provided have been informed that their requests to the Service may be processed for technical support and statistical purposes in accordance with the Privacy Policy, published on the website at www.casus.legal/privacy.html.

11.2. The personal data of the Customer’s representative (contact email address, as well as the surnames and given names of employees who receive codes, if the Customer specifies them in the personal account) are processed by the Operator to the extent necessary to perform the contract, in accordance with Federal Law No. 152-ФЗ of 27.07.2006 “On Personal Data” and the aforementioned Privacy Policy. The Customer guarantees that it has a lawful basis for transferring its employees’ personal data to the Operator.

12. Intellectual property

12.2. Payment for the package grants the Customer a limited, non-transferable, time-limited licence to use the connectors to the extent expressly provided for by this offer.

12.3. The Service database (a corpus of processed information on judicial acts) contains more than 10,000 independent information elements; accordingly, as its maker, the Operator holds the exclusive (related) right to extract and re-use its materials (Article 1334 of the Civil Code of the Russian Federation). The Customer and its employees are prohibited from extracting (transferring all or a substantial part of the contents to another medium) and re-using a substantial part of the database materials, as well as repeatedly extracting and re-using insubstantial parts of its materials, if such actions contradict the normal use of the database or prejudice the legitimate interests of the Operator. A violation entails liability prescribed by law and constitutes grounds for suspension and blocking of access.

13. Amendment of the terms and final provisions

13.1. The Operator may amend this offer. Amendments take effect upon publication; periods already paid for are performed under the terms in effect on the payment date.

13.2. The contract is governed by the law of the Russian Federation. Disputes shall be resolved through negotiations or, if no agreement is reached, through court proceedings.
