User Agreement

0. Parties and Details

The Service is provided by the sole proprietor Aleksei Sharapov (OGRNIP 325774600322644, TIN 773001860255) — hereinafter the “Contractor”.

By accessing the Service, the User enters into a contract with the Contractor. Payments are collected on behalf of the Contractor (see Section 9).

1. Acceptance of Terms

By accessing or using the Service, you confirm that you have read, understood, and agree to be bound by this User Agreement ("Terms").

If you do not agree to these Terms, you must not access or use the Service.

2. Description of Service

The Provider offers the Service under the terms of this Agreement. The Service allows registered users to communicate and submit requests to AI models directly or through preconfigured AI roles/personas with automatic model selection. The cost of a request is specified in Sparks (Spark Wallet plan) or calculated in USD based on actual usage (Pro plan).

We may add, modify, or remove features at any time without prior notice.

3. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your jurisdiction) to use the Service.

By using the Service, you warrant that you have the legal capacity to enter into these Terms and that all account information you provide is accurate and complete.

4. User Content

You remain solely responsible for the content you submit, transmit, or display through the Service ("User Content") and for compliance with all applicable laws.

By posting User Content, you grant us a worldwide, non-exclusive, royalty-free licence to host, store, reproduce and display that content solely for operating and improving the Service.

5. Acceptable Use

You agree not to use the Service to generate or share content that violates the acceptable-use policies of any integrated Model Provider, including (but not limited to) disallowed content under OpenAI’s Usage Policies or Anthropic’s Terms of Service. Violation results in blocking without refund.

We may monitor activity and remove or restrict access to accounts or content that we reasonably believe breaches these rules or applicable law.

6. Intellectual Property

Except for User Content, all software, text, graphics, trademarks and other materials that form part of the Service are owned by us or our licensors and are protected by law.

No rights are granted to you other than as expressly set out in these Terms.

7. Privacy and Data Protection

Our collection and processing of personal data are governed by our Privacy Policy and, where applicable, the General Data Protection Regulation ("GDPR").

You have the right to access, rectify, erase and restrict processing of your personal data as described in the Privacy Policy.

8. Third-Party Models

Outputs generated by Model Providers are provided "as is" without warranty. We do not control or endorse the content returned by third-party models.

By using these features you instruct us to transmit your prompts to the relevant Model Provider, which may process them to generate responses.

Within AI roles, the specific model and its version may be selected automatically; the composition of Model Providers may change without notice.

9. Fees and Payment

9.1 Some features require payment of fees. Charges are processed on behalf of sole proprietor A. V. Sharapov; current prices are displayed at checkout.

9.2 By topping up you acknowledge that funds are non‑refundable except where mandatory law provides otherwise. Refunds of RUB payments are converted back to USD at the Bank of Russia rate + Exchange‑rate margin applicable on the refund date.

9.3 Sparks. Sparks are an internal accounting unit of the Service and are not legal tender, currency, or securities. Sparks serve exclusively for accounting and payment of requests within the Service and are not subject to exchange for money, redemption, or withdrawal outside the Service.

9.3.1 Spark Wallet Plan. The User purchases Spark packages; each purchase forms a separate Batch of Sparks with a validity period of 6 months from the date of crediting. Upon expiration, unused Sparks expire without compensation, unless otherwise required by mandatory legal provisions.

9.3.2 Deduction Procedure. Sparks are deducted from batches with the nearest expiration date (FEFO). The cost of a request in Sparks is fixed at the moment the request is accepted for processing by the Service.

9.3.3 Rounding and Minimum Deductions. Deductions are made in whole numbers of Sparks; fractional values are rounded up to the nearest whole Spark. For partially completed or interrupted requests, the actual cost is deducted, but not less than 1 Spark.

9.3.4 Transfer and Use. Sparks belong to the User's account, may be distributed among their projects/workspaces within the Service, but may not be transferred to another account without our written consent.

9.3.5 Changes to Spark Prices. Spark rates for models and AI roles may change at any time; the new cost applies to requests accepted for processing after the publication of changes.

9.3.6 Promo Sparks and Bonuses. Promo Sparks awarded as part of promotions/referral programs have a shortened validity period (specified upon crediting), are not subject to exchange for money, and may have usage restrictions.

9.4 Settlement currency and conversion.

9.4.1 All monetary obligations of the parties are fixed in US dollars (USD) and are stored on the users' Balances in USD.

9.4.2 For users with Russian payment cards, the Service accepts payments in Russian rubles (RUB) — this is a requirement of paragraph 1 of Article 16.1 of Federal Law No. 161 "On the National Payment System".

9.4.3 Conversion RUB → USD and the reverse display USD → RUB are performed daily (≈18:00 MSK) at the official Bank of Russia rate plus a 4 % margin.

9.4.4 The amount in RUB displayed in the interface is for informational purposes only; if the Central Bank of the Russian Federation exchange rate fluctuates, it may change without any separate notice. The User agrees that the dollar balance is final on the Balance.

9.4.5 At the time of replenishment, the User enters the amount in RUB; the corresponding equivalent in USD is credited to the Balance, calculated at the rate in effect at the time of payment authorization.

9.5. Risk of currency fluctuations. The User assumes the risk of changes in the RUB/USD exchange rate between the time of replenishment and the time of debiting funds.

9A. Referral Program

9A.1 The Service provides a referral program that allows users to receive bonuses for attracting new customers.

9A.2 Each user receives a unique referral code. A new user who applies a referral code during their first balance top-up receives a bonus of 10% of the payment amount.

9A.3 The owner of the referral code receives a commission of 5% from each payment made by the referred user. The commission is credited to the code owner's bonus account.

9A.4 The bonus account is maintained separately from the main balance. Funds from the bonus account can be transferred to the main balance and used to pay for Service features. Withdrawal of bonus funds outside the Service is not provided.

9A.5 A referral code can only be used during a new user's first payment. One user can use only one referral code during their entire time using the Service.

9A.6 We reserve the right to suspend or terminate any user's participation in the referral program if we suspect fraud, creation of fictitious accounts, or other violations of the program terms.

9A.7 The terms of the referral program may be changed or the program may be terminated at any time with user notification. Bonuses accumulated before the changes are preserved.

9B. Pro Plan (Pay-as-you-go)

9B.1 Account Balance. Calculations under the Pro plan are conducted in US dollars (USD) from the User's Account Balance. The Account Balance is topped up in advance; as usage occurs, amounts in USD are deducted for actual model/API calls at current rates.

9B.2 Pricing Methodology. Cost is calculated based on usage volumes (e.g., input/output tokens, session duration, API calls) and our applicable rates/coefficients for the respective Model Providers. We may change rates and calculation methodologies prospectively; changes apply to usage after publication.

9B.3 Rounding and Billing Delays. Charges may be processed with a technical delay and may include rounding to minimum billing increments published in the interface.

9B.4 Limits and Auto-replenishment. When the balance is zero or negative, access to paid Pro features may be suspended. The User may set spending limits and/or auto-replenishment using a saved payment method.

9B.5 Absence of Sparks on Pro Plan. Sparks are not used or deducted when working under the Pro plan, except for explicitly specified mixed features.

9C. Use of Own API Keys (BYOK)

9C.1 By providing keys, the User confirms their right to use them and instructs us to store and use them exclusively for proxying requests. We store keys in encrypted form and do not transfer them to third parties except to the Model Provider for request execution.

9C.2 The User bears full responsibility for costs and terms with third parties related to their keys and undertakes to bear all such payments. Deletion of a key by the User terminates access to the corresponding features; accrued amounts are non-refundable.

9C.3 If key compromise is suspected, we reserve the right to temporarily block its use pending investigation.

9D. Changes to Prices and Limits

9D.1 We reserve the right to change Spark prices, Pro rates, limits, and usage restrictions at any time. Material changes are published in the interface; continued use after publication constitutes acceptance of the changes.

10. Termination

We may suspend or terminate your access to the Service at any time, with or without notice, if we reasonably believe you have violated these Terms.

You may stop using the Service at any time. Sections 7–13 survive termination.
