ChessYOUR DATA, YOUR CHOICES
Privacy policy
Effective September 8, 2026, updated October 5, 2026. ChessReign is operated by Nyza Creations LLC. Contact [email protected] about your personal information.
Information we use
When you register, we store your email address, display name, a securely hashed password when you use one, and your account preferences.
We store online games, moves, clock outcomes, ratings, training progress and reviews to provide the service. Display names, ratings and game moves are visible to opponents and to people with a game link. Your email, password and private training records are not shown to opponents. Guest online play uses a temporary account identifier. Local practice and board preferences are stored on your device.
Our hosting, security and email services process connection details such as IP addresses, approximate country inferred from IP addresses, request times, technical errors and message delivery events. Cloudflare uses this connection information for delivery, security and traffic diagnostics. This is separate from device location permissions, which the native app does not request. Support messages, fair play reports and blocking preferences are used to answer requests and investigate abuse.
Free first release
This release has no subscriptions or in-app purchases. ChessReign does not collect payment information.
Why we process information
We use information to deliver requested games and account features, keep the service secure, recover accounts and meet applicable legal obligations. Where applicable, our legal bases are providing the service you request, legitimate interests in security and reliability, legal obligations, and consent for optional features. We do not sell personal information or use it for targeted advertising.
Services that help us operate
ChessReign uses OVHcloud for hosting, Cloudflare for DNS, delivery and security, and Nyza Mail with Amazon Web Services for account and support email. Apple and Google provide store distribution and testing services for their respective mobile platforms. Service providers receive information needed for their functions. Information may be processed in the United States and other locations where these providers operate.
Device storage and web cookies
In the native app, sign-in tokens use the operating system’s secure storage. Offline practice, saved game history, settings and training progress remain on your device. The native app includes no advertising or analytics SDK. Use Sign out to remove this device’s sign-in token; online account records are managed separately in Settings.
An essential cr_session cookie keeps you signed in, for guests as well as members; it cannot be switched off because the service does not work without it. Your board preferences, practice positions and training progress are kept in your browser's local storage on that device. Cloudflare, our edge network, sets a short-lived __cf_bm cookie to tell people from bots.
We use Google Analytics 4 to see, in aggregate, which lessons and puzzles get used and where people drop off. It runs only after you accept analytics in the cookie banner, in every jurisdiction; until then the Google tag is not loaded and Google Consent Mode stays denied. There are no advertising cookies and no cross-site tracking. A browser Global Privacy Control signal is honoured as an opt-out. The full inventory and the withdrawal control are in our cookie policy, and you can change your choice at any time from Cookie preferences in the menu.
Retention and deletion
Account information and saved progress remain while you use the account. You can delete your account in Settings or follow the account deletion instructions. Deletion removes your email, password, sign-in sessions, training progress and reviews. An anonymous record of completed games remains for your opponents. Limited security and abuse records may be retained when needed for legal compliance, fraud prevention or resolving disputes. Operational backups expire according to the backup retention schedule and are not used to restore deleted accounts into active service.
Your rights
You can edit your display name, export your account data and delete your account in Settings. Depending on your location, you may also have rights to access, correct, restrict, object to or request erasure of information, withdraw consent, or complain to your local privacy authority. Email us for help; we may verify that the request concerns your account before responding.
Children
ChessReign accounts are intended for people aged 13 and older, or the higher age required for independent consent in your location. If you believe a child has provided information without the required consent, contact us so we can investigate and remove it.
Changes
We update this policy when our practices change. The effective date above identifies the current version. We provide notice of material changes where required.
