Effective date: November 4, 2026
These Terms of Service (“Terms”) govern your use of the Hollow Chess mobile game (the “App”), provided by Galactic Toast (“we”, “us”). By downloading, installing or using the App, you agree to these Terms. If you do not agree, do not use the App.
We grant you a personal, non-exclusive, non-transferable, revocable license to download and use the App on devices you own or control, for your own non-commercial entertainment, subject to these Terms and to the terms of the store from which you got the App (Google Play or the Apple App Store).
You can play as a guest — your profile (a display name and an avatar), progress, statistics, match history and replays are stored on your device. You may optionally create an account by signing in with Google, with Apple, or with an email and password to sync your progress, play rated online matches and appear on leaderboards. Sign-in is handled by Google Firebase Authentication, and we never receive or store your password. You are responsible for keeping your sign-in credentials secure and for activity under your account. Your display name is shown publicly (to opponents and on leaderboards), so do not include personal information in it. You must not create multiple accounts to manipulate rankings or evade enforcement. See our Privacy Policy for what account data we store.
We do not tolerate objectionable content or abusive users. This includes offensive, hateful, sexual or harassing display names, and abuse of other players.
You agree not to:
Display names are screened by an automated filter, and we use automated systems to detect cheating and unfair play. Where you breach these Terms or act in a way that harms other players or the service, we may, at our discretion, reject, change or remove a display name, void affected games and adjust or reset ratings, and suspend, remove or terminate your account or your access to online features. Some of these measures may be automated.
Content you create, such as display names, avatars, custom levels and boards you carve and send (Carve & Send), remains yours. You are responsible for it and confirm you have the right to use it. For content that is transmitted through the service (for example, your display name shown to an opponent during an online match, or a carved board and your display name shown to anyone who opens its link), you grant us a limited license to host and transmit it solely to operate the App. We may remove content that violates these Terms.
To report an offensive display name, tap the name on a leaderboard, or use “Report” on the result screen of an online match. To report a carved board, use “Report board” on that board. In the iOS app you can also block a player with the same control: a block hides the player from your leaderboards and keeps the two of you apart in online matchmaking, and you can undo it in Settings → Blocked players. The Android app has reporting only.
We review reports within 24 hours. When a report is valid, we change or remove the name, and we can suspend or remove the account. You can also contact us at galactictoast.dev@gmail.com.
Online matches connect you with other players in real time. When no other player is free, the queue can pair you with a computer opponent; in the current App, games against a computer opponent from the queue do not change your rating. You are expected to play fairly and treat other players with respect. We are not responsible for the conduct of other players.
The App is free to download and play, and it shows no ads. It offers one optional in-app purchase, Hollow Pro, a one-time purchase that adds extra features (for example new looks and finishes, Carve & Send and the older Hollow boards). Everything that was free before Hollow Pro stays free, and Hollow Pro gives no advantage in rated play. The App lists what Hollow Pro includes before you buy.
Purchases are made through Google Play or the Apple App Store and are subject to that store’s terms, including its refund rules. A purchase belongs to the store account that made it; the App restores it on a new device that uses the same store account.
Founder Pro. Players who used the Android App before 5 November 2026 can claim Hollow Pro for free (“Founder Pro”). Claimed while signed in, Founder Pro stays with your account for as long as the account exists and the App offers Hollow Pro. Claimed as a guest, it stays on that device only; sign in to keep it on a new device. Founder Pro has no cash value and cannot be transferred.
We may change what Hollow Pro includes, add to it, or introduce other optional purchases in the future; we will not take away a feature that you have already bought without offering a fair replacement or refund where the law requires it.
We may update, change, suspend or discontinue the App or any of its features (including online multiplayer) at any time, without liability. We do not guarantee that the App or its online services will always be available, uninterrupted or error-free.
The App is provided “as is” and “as available”, without warranties of any kind, whether express or implied, to the maximum extent permitted by law, including any implied warranties of merchantability, fitness for a particular purpose, and non-infringement.
To the maximum extent permitted by applicable law, we will not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of data, arising out of or related to your use of the App. Nothing in these Terms limits liability that cannot be limited under applicable law, including your mandatory rights as a consumer.
You may stop using the App at any time, sign out, and permanently delete your account and cloud data in Settings → Delete cloud account (or via our Delete Your Data page); uninstalling removes on-device data. We may suspend, remove or terminate your account or your access to the App’s online features if you breach these Terms or act in a way that harms other players or the service.
We may update these Terms from time to time. Material changes will be posted on this page with an updated effective date. Your continued use of the App after changes take effect constitutes acceptance of the updated Terms.
These Terms are governed by the laws of Poland, without prejudice to any mandatory consumer-protection rights you have under the laws of your country of residence. Disputes will be subject to the competent courts, subject to any mandatory consumer jurisdiction rules that apply to you.
