CrunchChess ("we", "our", or "us") respects your privacy and is committed to protecting your personal information — and, because many of our users are children, the privacy of young learners in particular. This Privacy Policy explains what information we collect, how we use it, how long we keep it, and the choices and rights available to you.
By creating an account or using CrunchChess, you agree to the practices described in this policy.
Account information. When an account is created, we may collect a name or username, an email address, chess training preferences, and account settings or profile information.
Training information. To provide personalized training and progress tracking, we collect puzzle results, training activity, session history, progress metrics, and achievements or milestones.
Parent information. If a parent or guardian chooses to receive updates, we collect the parent email address, email subscription preferences, and the delivery/confirmation status of parent reports.
Technical and usage information. We may automatically collect browser type, device information, IP address, usage statistics, in-product activity/events, and error logs or performance information. We use this for first-party product analytics — to understand how features are used and to improve the platform. We do not use this information to serve advertising.
We use information to provide chess training services; track progress and performance; deliver parent reports; send account-related communications; improve platform functionality; understand feature usage through analytics; monitor system performance and security; and respond to support requests.
We do not sell personal information, and we do not use children's information for advertising or behavioral targeting.
Parents or guardians who opt in (and confirm their email address) may receive weekly progress reports, training summaries, product updates, and service notifications.
Parent report emails are sent only after the recipient confirms their address (double opt-in). Parents may unsubscribe from non-essential emails at any time using the unsubscribe link included in those communications, or by asking the student to turn off reports in their CrunchChess settings.
CrunchChess is designed to be used by young chess players with the involvement of a parent, guardian, school, coach, or chess program.
Account model. Accounts are intended to be created and overseen with adult involvement. If your child is under 13 (or under the minimum age of digital consent in your country), a parent or guardian should create and manage the account on the child's behalf and supervise its use.
What we collect from children. We collect only the information needed to provide the training service — a username/login, training activity, and progress data. We do not require a child to disclose more information than is reasonably necessary to use CrunchChess.
No advertising to children. We do not show third-party advertisements and we do not use children's information for advertising, profiling for marketing, or behavioral targeting.
Parental rights. Parents and guardians may review the personal information associated with their child's account, request that we correct it, or request that we delete it and terminate the account. To make a request, contact us at the address in Section 13. We may need to verify that you are the parent or guardian before acting on the request.
We do not sell personal information. We share information only:
We rely on a small set of reputable infrastructure and service providers to run CrunchChess. They process information only to provide their service to us:
We use reasonable technical and organizational measures to protect information. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
Our service providers are located in the United States, so information may be processed and stored in the U.S. or other countries. If you access CrunchChess from outside these regions, you understand that your information may be transferred to, and processed in, locations whose data-protection laws may differ from those in your country.
We retain information for as long as reasonably necessary to provide the service, maintain records, improve the platform, and comply with legal obligations.
When an account is deleted, we remove the associated personal information from our active systems. Residual copies may remain in routine encrypted backups for a limited period until those backups are rotated out of retention, after which they are deleted.
Users (or a parent/guardian on a child's behalf) may request deletion of an account by contacting us.
Depending on where you live, you may have rights to:
To exercise any of these rights, contact us at the address in Section 13. We will respond within a reasonable timeframe and as required by applicable law, and we may need to verify your identity (or your status as a parent/guardian) first.
CrunchChess uses cookies and similar local-storage technologies to maintain login sessions, remember your preferences, and measure platform performance and feature usage. We do not use third-party advertising or cross-site tracking cookies. Most browsers let you control or clear cookies and local storage, though disabling them may affect how the service works.
CrunchChess may contain links to third-party websites or services. We are not responsible for the privacy practices or content of those third parties, and we encourage you to review their privacy policies.
We may update this Privacy Policy from time to time. When we do, we will post the updated version on the CrunchChess website with a revised "Last Updated" date. Material changes will be communicated by reasonable means.
If you have questions about this Privacy Policy, or wish to request access, correction, deletion, or export of information (including on behalf of your child), please contact:
