Terms of use for Grand Skat

These terms govern the use of the game Grand Skat (the websites grandskat.com, grandskat.de, weldowo.pl and the apps for Android and Windows). Last updated: 1 November 2026.

1. Provider

Robert Świerkosz, ul. Wrocławska 30, 41-103 Siemianowice Śląskie, Poland, email admin@neuragrowth.co, phone +48 728 765 901. The game is published under the name NeuraGrowth. The provider is a natural person carrying out unregistered activity under Polish law (Art. 5 of the Polish Entrepreneurs' Law), without a VAT number or register entry.

2. What we offer

• Playing Skat online with other people and against bots, offline in the apps, plus lessons, the daily puzzle, a bid calculator and a score sheet. Without an account you play as a guest.
• Free account (nickname, email, password): ranking, statistics, achievements, friends, private tables.
• Premium (one-time purchase, no subscription): extra decks, rooms, avatars, frames, the coach and hand analysis, unlimited offline play. You buy premium in a store: Google Play, Microsoft Store or itch.io. The Windows app from a store includes premium. Premium on your account works on every platform once you sign in.

The game has no ads, no playing for money and no physical prizes. Points and ranking have no monetary value.

3. Technical requirements

A current browser (Chrome, Firefox, Edge, Safari) with JavaScript enabled, or the app for Android 7.0 or newer, or the app for Windows 10 or 11 (64-bit). Online play needs an internet connection. Using the internet carries the usual risks (for example stolen passwords or malware); use a separate password for the game and keep your software up to date.

4. Account and conduct

• The contract for the account is concluded when you register and runs for an indefinite period. The account is free.
• One account per person. Keep your password to yourself.
• Your nickname must not break the law or infringe anyone's rights, must not be vulgar or offensive and must not impersonate another person, the publisher or game staff.
• It is forbidden to provide unlawful content, to manipulate the ranking (for example several accounts at one table or arranged results), to use programs that play for you, and to try to disrupt the server.
• Table rules (leaving a game, time to move, chat from fixed phrases) are described in "How we play at Grand Skat" under Rules.
• Minors use the game with the knowledge of a parent or guardian; store purchases are subject to the store's parental controls.

5. Reporting and moderation

• Report a player who breaks these terms in the game via "Send feedback" (category "Report a player") or by email to admin@neuragrowth.co. Under Friends you can also hide a player: they can no longer invite you and their table chat is not shown.
• admin@neuragrowth.co is the point of contact for users and authorities under Articles 11 and 12 of the Digital Services Act (DSA). We reply in English, German and Polish.
• We review reports without undue delay. In case of a violation we may change the nickname, restrict online play or delete the account. We tell you the decision and the reason at your account's email address; you can appeal by replying to that message.

6. Termination

• You can delete your account at any time: Profile → "Delete account forever", or by email to admin@neuragrowth.co (details at weldowo.pl/usun-konto.html).
• We may terminate the contract for good cause (serious or repeated violations of point 4) or when the game is discontinued, with 30 days' notice announced in the game.

7. Purchases, right of withdrawal and complaints

• Premium is digital content. Payment, receipts and refunds are handled by the store you buy from, under its own terms.
• Google Play and Microsoft Store: the store informs you at checkout about the right of withdrawal and its loss once delivery of the digital content begins; request a refund in the store.
• itch.io (here the provider is the seller): you may withdraw from the purchase within 14 days without giving a reason by writing to admin@neuragrowth.co; the refund is made via itch.io within 14 days of receiving your notice. No form is needed, a message with the email address used for the purchase is enough.
• We are responsible for the conformity of the digital content with the contract under consumer law. Send complaints (including about how the game works) with a description and your nickname to admin@neuragrowth.co; we reply within 14 days.

8. Privacy

How we process personal data is described in the Privacy policy (in the game menu and at grandskat.com/privacy.html).

9. Changes and governing law

• We announce significant changes in the game at least 14 days before they take effect. If you do not agree, you can delete your account.
• Polish law applies, without prejudice to the mandatory consumer protection rules of your country of residence.
• We are not obliged to take part in proceedings before an alternative dispute resolution body, but we are happy to resolve any issue directly.
