Public service agreement (offer)

Revised 12 November 2026.

This is a translation; the Ukrainian text of the agreement prevails.

This document is a public offer to conclude an agreement on paid access to the Predok connector. The Predok site (cards, wiki, help) and the Basic plan are free; only the Terms of use apply to them.

1. Parties and terms

Provider — sole proprietor (FOP) Serhii Valentynovych Adamchuk (Адамчук Сергій Валентинович), taxpayer number 2904300231, single-tax payer of the third group, not a VAT payer.
Customer — a person with a Predok account who has paid for a pass.
Connector — access to Predok records (the Ukrainian genealogical database) from an AI assistant or another program on behalf of the Customer’s account.
Request — the unit of accounting of connector use. How many requests each operation costs is stated on the plans page.
Plan — a limit of requests per 30 days. The free plan is Basic; the paid plans are Researcher and Pro.
Pass — a paid right to use a paid plan for a set term: 30, 90 or 360 days.

2. Subject

The Provider gives paid access to its own online information system Predok (predok.ai). The system holds a structured genealogical database: records about historical persons, family ties, events and archival sources. The Customer searches and retrieves these records independently through the connector — from their AI assistant or another program.

Access is given within the limit of the chosen plan for the term of the pass, and the Customer pays for the pass.

This is a service, not a sale of goods: the Customer receives no copy of the database, no files and no rights to the data. How Predok records may be used is set by the Terms of use.

3. Conclusion of the agreement

The agreement is concluded when the payment for a pass is received. By paying for a pass, the Customer confirms having read this agreement, the Terms of use and the Privacy policy, and agrees to them. No signature or paper copy is needed.

The agreement is in force until the pass ends.

4. Price and payment

Prices of passes are published on the plans page, in hryvnias. The price at the moment of payment applies; a price change does not affect passes already paid for.
Payment is one-time, by bank card through the LiqPay payment system. If the card is in another currency, the Customer’s bank converts the amount at its own rate.
The Provider does not receive or store card data.
There is no auto-renewal: a pass ends by itself, and nothing is charged without a new payment by the Customer.
The Customer receives a payment confirmation from the payment system and sees the current pass in their account.

5. Pass

A pass is valid right after payment and is tied to the account it was paid from. It cannot be moved to another account.
The plan limit is given for every 30 days from the start of the pass. Unused requests do not carry over to the next 30 days.
So that a software error cannot spend the whole limit, only a part of it can be spent in one day; the part is stated on the plans page.
Failed calls (an error or a timeout) spend no requests.
Another pass of the same plan adds its days to the end of the current one. A pass of a higher plan is valid at once, and the days of the current lower-plan pass wait and continue after it.
When a pass ends, the Basic plan applies. The account and its data stay.

6. Refunds

By paying for a pass, the Customer agrees that the service starts at once. Therefore, after a pass has started, the Customer cannot withdraw from the agreement and get a refund for that pass, including for unused days or requests.

The Provider refunds the payment or, at the Customer’s choice, extends the pass if:

a payment went through twice, or the pass did not appear in the account;
the connector was down through the Provider’s fault for more than 72 hours in a row: the pass is extended by those days, and if the outage is longer than 14 days, the Customer may get a refund for the unused days.

To ask for a refund, write to admin@predok.ai from the address of your account and give the date and amount of the payment. We answer within 5 working days. Money is returned to the same card; how long it takes depends on the bank.

7. Duties of the parties

The Provider:

gives access to the connector within the paid plan;
announces planned downtime on the site;
says directly when the limit is used up and when it is restored.

The Customer:

follows the Terms of use, in particular does not bypass limits or collect data in bulk;
does not give access to their account to other people.

If the Customer breaks the Terms of use, the Provider may stop access. The payment for the pass is not refunded in that case.

8. Quality and liability

The service is access to the connector, not a research result. The Provider does not guarantee that the database holds records about a particular person, family or place, or that the records are complete and accurate: they come from archival sources and may repeat errors of the source.
The Provider is not responsible for AI assistants and other third-party programs through which the Customer uses the connector, or for their cost.
The Provider’s liability is limited to the amount the Customer paid for the current pass.
The parties are not liable for failing to perform the agreement because of circumstances beyond their control: hostilities, power and communication outages, decisions of authorities. If the connector was down because of such circumstances, the pass is extended by those days.

9. Personal data

To perform the agreement, the Provider processes the email address of the account, payment details (date, amount, payment number, status) and the request log. See the Privacy policy for details.

10. Changes and disputes

A new edition is published on this page with a new date and applies to passes paid for after publication. For a pass already paid for, the edition in force at the moment of payment applies until the pass ends.
The agreement is governed by the law of Ukraine. The parties first settle disputes by correspondence; failing that, in court under the law of Ukraine.
