Terms of Use

Effective date: 17 September 2026 · Please read this license carefully before using the app.

1. Agreement definitions

This is a License Agreement (“Agreement”) between you (the end user) and Mikhail A. Matveev (“Developer”), governing the use of the Kozel Card Game application (“App”) on any platform on which it is distributed, including versions distributed on the Apple App Store by its publisher, Elizaveta Fragner (see the Impressum).

2. Grant of license

Upon installation and use of the App, you are granted a non-exclusive, non-transferable, non-sublicensable, revocable license to use the App for personal purposes on devices that you own or control, subject to the terms and conditions of this Agreement and the usage rules of the store from which you obtained the App.

3. Intellectual property rights

All intellectual property rights associated with the App — including but not limited to copyright, trademarks and artwork — belong solely to the Developer. This Agreement does not constitute a sale or a transfer of any intellectual property rights. The game of Kozel itself is a traditional card game in the public domain; nothing in this Agreement asserts any claim over the rules of the game.

4. Terms of use

• You may install and use the App for personal entertainment.
• You may not distribute, lend, lease, sublicense or otherwise make the App available to third parties for commercial purposes.
• You may not modify, reverse engineer, decompile, disassemble or derive source code from the App, except to the extent such a restriction is prohibited by applicable law.
• When playing online, you agree to play fairly and not to attempt to disrupt the game service or other players.

5. Online service

The multiplayer service is provided free of charge and without any guarantee of availability. The Developer may modify, suspend or discontinue it at any time. Access may be withdrawn from any player who abuses the service, attempts to disrupt matches or interferes with other players' enjoyment of the game.

6. Full version

The App is free to download and free to play. It offers one optional in-app purchase — the full version, which unlocks the Master opponent, opening an online room of your own, the individual table rules and the other table felts. It is bought once, never expires, and is not a subscription.

The purchase is tied to the Apple or Google account it was made from, and Restore purchase returns it on a new device. Because the payment is taken by the store and not by us, refunds are requested from that store and granted under its policy: the Developer and the Publisher cannot issue them directly. This does not limit your statutory consumer rights.

7. No warranty

The App is provided “as is” and “as available”, without warranty of any kind, express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose and non-infringement. The Developer does not warrant that the App will be uninterrupted or error-free.

8. Limitation of liability

To the maximum extent permitted by applicable law, the Developer shall not be liable for any indirect, incidental, special or consequential damages arising out of or in connection with the use of, or inability to use, the App. Nothing in this Agreement limits liability for damages caused intentionally or by gross negligence, or for injury to life, body or health.

9. Statutory rights

Nothing in this Agreement affects your mandatory statutory rights as a consumer under the law of your country of residence.

10. Changes to these terms

The Developer may update this Agreement as the App changes. The current version is always the one published on this page, with its effective date at the top.

11. Governing law

This Agreement is governed by the law of the Federal Republic of Germany, excluding its conflict-of-law rules and excluding the UN Convention on Contracts for the International Sale of Goods, without depriving a consumer of the protection of the mandatory law of their habitual residence.
