License Agreement (EULA)

Revision 2 dated 30.08.2026

This English text is a translation of the Russian original and is provided for convenience. In the event of any discrepancy between the English and the Russian version, the Russian version prevails.

1. Acceptance of the terms

By using our service (hereinafter — the "Service"), you automatically accept all the terms of this Licence Agreement. If you do not agree with any of the terms, please do not use the Service.

We may amend the terms of the agreement at any time by publishing an updated version in the Service together with the date on which it takes effect. Amendments do not apply to purchases already made or to Coins already paid for. If you do not agree with the amended version, you are entitled to discontinue use of the Service on the terms of section 10. Continued use of the Service after the effective date of the amendments constitutes agreement with the updated version.

2. Definitions

Service — the query console (processing of .epf files) and the AI assistant associated with it
Console — the program for processing .epf files: a query builder, an editor with syntax highlighting, parameters, temporary tables, drill-down of results, background execution and export to Excel. It is purchased once and works without an internet connection and without Coins
AI assistant — a tool that helps to write and refine queries using the artificial intelligence technologies of a third-party provider; requests to it are paid for with Coins
User — a natural or legal person using the Service
Coins — a single internal balance used to pay for requests to the AI assistant across several of our tools, including this Service
API — the programming interface for integrating with the Service

3. What you acquire, and the licence to use the software

3.1 Separation of the Console and the AI assistant

The Console and the AI assistant are two different products, kept separate from each other:

The Console is yours forever after purchase and works entirely independently of Coins and of an internet connection
The AI assistant is a separately paid add-on: without Coins the Console remains fully operational, simply without AI help in writing queries

3.2 The licence granted

We grant you a personal, non-exclusive, non-transferable licence to use the Console and, where paid access is held, the AI assistant, subject to the terms of this agreement.

The licence is personal because it is bound to your account: an account belongs to one individual, and everything done with its keys is treated as done by you. The licence sets no limit on the number of computers you work from or the number of databases you connect to.

3.3 Usage restrictions

You are entitled to:

Adapt the client-side part of the software to your needs for personal purposes
Use the software in any number of databases, including your clients' databases, and be paid for that work

You are not entitled to:

Modify, decompile or disassemble the server-side part of the software or the API
Attempt to obtain the source code of the server-side part
Carry out any reverse engineering of the server-side part
Resell the software or the licence to it, transfer either for a fee, rent it out or sublicense it, in whole or in part
Provide third parties with paid access to the running software: selling queries, key access, or the output of the AI assistant as a standalone service
Remove or alter any copyright or licence notices
Use the Service to create a competing product
Store the output of the AI assistant at scale for the purpose of avoiding payment

The line is simple: being paid for your own work is fine; being paid for access to the software is not.

4. Payments and payment methods

4.1 Purchasing the Console

A one-off purchase grants permanent access to the Console
After the purchase you will receive a licence key for activation
With a paid purchase, starting Coins are credited on a one-off basis in the quantity stated on the product card — they are included in the price of the Console and are provided as a bonus
The licence is deemed delivered from the moment the data processor file is downloaded: the file stays with you, and no refund of the money paid for the Console is made after the download. This does not limit your mandatory consumer rights under clause 9.3
Upon registration of an account, trial Coins are credited on a one-off basis in the quantity stated in the Service; they are provided free of charge, are not linked to the purchase of any product, and are not refundable or withdrawable under any circumstances

4.2 Donations

Donations are voluntary payments made through the "Support" button to support the development of the Service
Donations are not a purchase of goods or services and do not imply any consideration on our part
As a token of gratitude we may, at our discretion, provide bonuses, early access to materials or other tokens of appreciation — this is not guaranteed, does not depend directly on the size of the donation, and may not be regarded as a condition or as the subject matter of a transaction
Donations are non-refundable

4.3 Payment methods

Payments are processed through third-party payment providers (Robokassa, CloudPayments). The available payment methods are shown on the payment page depending on your region and the provider.

All payments are processed on secure servers using modern encryption. We do not store your payment information on our servers.

5. Internal currency (Coins)

5.1 Definition and use

Coins are a single internal balance used to pay for requests to the AI assistant within this Service and within our other tools that use the same balance
Coins cannot be exchanged for real money and are non-refundable while the account remains in active use — save in the case of closure of the account at your initiative on the terms of section 10.3
Coins have no expiry date. We may write off unused Coins after one year of no activity in the account
They are used only in accordance with the Service's price list

5.2 Purchasing coins

The cost of coins and services is set out in the "Prices and cost" section. Prices may change no more than once a day.

5.3 Use

The remaining coins in your account are updated immediately after a successful payment. Coins that have been spent are not refunded, except in the cases expressly set out in clause 5.1. We are not liable for the accidental spending of coins. Where there is a balance, coins are deducted automatically on each request to the AI assistant.

6. Terms of use of the API

6.1 API access

The API is available only to registered users holding a valid API key
An API key is bound to the account holder's wallet: every request made with it is charged to that balance and made under the holder's responsibility, regardless of who made it
Publishing the key in the open, reselling API access, or granting it to third parties as a service — including as part of your own service, product or intermediary arrangement — is prohibited
The company reserves the right to block an API key if it is compromised

6.2 Request limits

A maximum of 2000 requests per hour
Exceeding the limit results in access being restricted for 1 hour
Repeated violations may lead to the account being blocked

6.3 Responsibility for use of the API

You are responsible for:

The security of your API key
The compliance of your use with the law
Compliance with our terms of service and usage policy

7. Prohibited activity

You undertake not to:

Use the Service for unlawful purposes or in breach of local, national or international law
Create content that infringes the rights of third parties (copyright, trademarks, personal data)
Generate content containing:
- Violence, cruelty or exploitation
- Discrimination on the grounds of race, sex, religion or nationality
- Sexual or erotic content
- Instructions for making weapons or narcotics
- Phishing, spam or social engineering
Store results at scale
Conduct DDoS attacks, scanning or security testing without permission
Use scripts, bots or automated tools without consent

7.1 Material involving the sexualisation of minors

The creation, requesting, storage or distribution through the Service of any material sexualising minors, in any form, is absolutely prohibited. This rule applies without exception.

Where such activity is identified, we immediately and without prior notice block the account with no right of restoration, retain the relevant data and pass the information to the competent law enforcement authorities. Sections 10.2–10.3 (on the blocking procedure and the refund of coins) do not apply to this clause.

8.1 Your content

You retain full rights to the content you create in the Service
You confirm that the content you submit to the Service does not infringe the rights of third parties
We log usage for security and diagnostic purposes

8.2 Our property

All content of the Service, including text, graphics, logos, images and program code, is protected by copyright
You may not reproduce, distribute or modify our content without written permission

8.3 Risks of AI generation and transfer of data to model providers

The output of the AI assistant is created using the artificial intelligence technologies of third-party providers and may lack the attributes of originality, and may coincide with results generated in response to requests by other users
By using such results, you assume the risks associated with a possible infringement of the exclusive rights of third parties
Neither we nor the providers of the AI models we use are liable for adverse consequences associated with these risks
When you make a request to the AI assistant, the content of your request is transferred to the third-party AI model provider to the extent necessary to process the request and deliver the result to you

9. Disclaimer of liability

9.1 "As is"

The Service is provided "as is", without any warranties. We do not guarantee:

Error-free operation or the absence of failures
The correctness of the output of the AI assistant
Security against unauthorised access (to a 100% degree)

9.2 Limitation of liability

We are not liable for:

Loss of data, profit or lost benefit
Your use of the output of the AI assistant
Decisions taken on the basis of the output of AI models
Interruptions in service for reasons beyond our control

The maximum of our liability: the amount of the payments you made over the preceding 30 days

9.3 Consumer rights

The provisions of this section do not limit or exclude your rights expressly provided for by consumer protection law, including the right to a reduction of the price of the service, to the cost-free remedy of defects and to compensation for losses caused by defects in the service (Art. 29 of the Law of the Russian Federation "On Protection of Consumer Rights"), as well as the right to withdraw from the contract and recover amounts paid for services not rendered (Art. 32 of that Law and Art. 782 of the Civil Code of the Russian Federation).

10.2 Procedure

In the event of a serious breach, the account is blocked immediately

Where the blocking is caused by a breach of the terms of the agreement, by fraud or by unlawful activity, the remaining Coins are not refunded

10.3 Closure at the user's initiative

You may close your account at any time through the settings
If the closure is not connected with blocking for a breach of the terms, the remaining paid Coins are refunded within 30 days, less the costs we actually incurred in accepting the payment (the payment provider's fee)
Starting Coins and bonus Coins that were not paid for with money are non-refundable
All data is deleted within 90 days of the request

You are also entitled to seek protection of your rights from Rospotrebnadzor or another authorised body
