Public Offer (Terms of Service)
Effective September 24, 2026
This document is a public offer (Article 437 of the Civil Code of the Russian Federation, hereinafter the Civil Code) by M. S. Birkin, self-employed individual (payer of the Russian professional income tax), Russian Taxpayer ID (INN) 481501685310 (hereinafter the Provider) to enter into an agreement on the terms below with any person with full legal capacity who is at least 18 years old (hereinafter the User).
1. Definitions
Service: the Krokki desktop software (hereinafter the App), the krokki.com website and related services on krokki.com subdomains. Model: an artificial intelligence system to which the User sends requests through the Service. Balance: the record of funds deposited by the User in rubles, from which requests are paid. Token: the unit of text volume by which a Model's requests are priced.
2. Subject of the agreement
2.1. The Provider grants the User, free of charge, a simple (non-exclusive) license to use the App on the User's devices worldwide for the term of the agreement (Articles 1286 and 1286.1 of the Civil Code) in the ways required to use it as intended: installation, launch and reproduction.
2.2. The Provider renders paid services giving the User access to Models through the Service, and the User pays for them at the prices on the Pricing page (Chapter 39 of the Civil Code).
2.3. The App is built on open-source software; the license terms for such components are provided in the App and prevail with respect to those components.
3. Acceptance
Acceptance of this offer (Article 438 of the Civil Code) is the registration of an account with confirmation of agreement to the offer. Topping up the Balance also constitutes agreement to the offer as in effect on the date of the top-up. The agreement is concluded for an indefinite term.
4. Account
The User provides accurate information, keeps the password and confirmation codes confidential, and is responsible for actions taken under the User's account. One account is intended for one person.
5. Balance, prices and payment
5.1. The User pays for subscriptions and tops up the Balance in the App through the payment service of Robokassa LLC. Funds deposited to the Balance are an advance payment for services. The Provider operates under the special tax regime “Professional Income Tax” and, after payment, issues a receipt in the “Moy Nalog” app, which is sent to the User's email.
5.2. The cost of each request is deducted from the Balance based on the number of input and output tokens and the prices of the selected Model in effect at the time of the request. Details of charges are available in the App. If the Balance is insufficient, the request is not executed. Server-side speech transcription (Clause 7.4) is charged to the Balance per minute, based on the duration of the processed audio and the per-minute price shown in the App before the transcription starts.
5.3. The Provider may change prices by publishing them on the Pricing page; changes do not apply to requests already completed. Funds on the Balance are not a deposit and no interest accrues on them.
5.4. The User may subscribe to a plan for a month or a year at the price on the Pricing page. For the paid period, a subscription gives access to the plan's features, including a monthly token allowance for the Models included in the plan and listed on the Pricing page (shared by all of them), which resets on the 1st of every month, Moscow time, and does not carry over. Without a subscription the free plan applies on the terms of the same page.
5.5. A subscription renews automatically for the same period by charging the card it was paid with, unless the User turns renewal off in the App before the paid period ends. The paid period stays active when renewal is turned off. If a renewal charge fails, plan access is kept for three days, after which the free plan applies.
5.6. A change in the subscription price applies from the next renewal and is published on the Pricing page at least 7 days before it takes effect.
6. Termination and refunds
The User may terminate the agreement at any time and receive the unused Balance, less the cost of completed requests, as described on the Refunds page, within 10 calendar days of the request. When a subscription is cancelled, the part of its price corresponding to the unused full days of the paid period is refunded.
7. Specifics of artificial intelligence
7.1. Model responses are generated automatically, are probabilistic in nature and may contain inaccuracies. The User checks the results before using them, especially in legal, financial, medical and other significant matters. The App shows the User changes to files before they are saved.
7.2. The list of Models and their developers is given on the Pricing page. Requests to Models from foreign developers are transferred outside the Russian Federation, as described in the Privacy Policy. The Provider may change the set of Models.
7.3. Rights to the results the User obtains with the Service, to the extent they are protected, belong to the User; the Provider makes no claim to them and does not use the content of requests to train models.
7.4. Speech transcription. The User may transcribe speech from their video or audio file in one of two ways. With local transcription, processing takes place on the User's device and no audio leaves the device. With server-side transcription (a paid service), the App extracts only the audio track from the video and uploads it in chunks to the Provider's servers in the Russian Federation (the Provider's own servers with graphics accelerators), where the audio is processed solely to produce the transcript. The audio and the transcript are not used to train models and are deleted from the servers right after the result is delivered, and in any case no later than 24 hours after upload. The transcript is saved in the User's project folder on their device. The cost of server-side transcription is calculated per minute in accordance with Clause 5.2.
8. Acceptable use
It is prohibited to use the Service to violate the laws of the Russian Federation, including to create or distribute prohibited information or malware, to commit fraud, to infringe the rights of third parties or to circumvent the Service's restrictions; to resell access to Models without the Provider's consent; or to create load that interferes with the operation of the Service. In the event of a violation, the Provider may suspend access with notice to the User; the remaining Balance is refunded under Section 6.
9. Liability
The Provider operates the Service with reasonable care but does not guarantee that it will be uninterrupted, including in the event of failures on the side of Model providers, telecom operators and payment services. The parties' liability is governed by the laws of the Russian Federation, including the Law “On Consumer Rights Protection”; the terms of this offer do not limit the statutory rights of a User who is a consumer.
10. Claims and disputes
Claims are sent to info@krokki.com or to info@krokki.com (a postal address for written correspondence is provided on request) and are reviewed within 10 calendar days. Disputes are resolved in court in accordance with the jurisdiction rules established by law, including at the place of residence of a User who is a consumer.
11. Changes to the offer
The Provider may amend the offer by publishing a new version on this page at least 7 days before it takes effect. Continued use of the Service after the new version takes effect means acceptance of it; if the User does not agree, the User may terminate the agreement under Section 6.
