Current Product Limits

  • Mystery Chess does not need payment card data for normal gameplay.
  • Precise location, country/residence payment eligibility details, contact lists, identity documents, and bank details are not needed for normal gameplay or tournament participation.
  • Ordinary and rated tournaments are free to enter and do not create a player financial account.
  • Website, Android, and iOS purchases are verified through their respective payment providers before account-level entitlements are granted.
  • Match/rating data may be corrected or reset when needed for integrity, testing, or service reliability.

Player Choices

  • Players can request account help, deletion, access, correction, or export through support.
  • We do not sell player personal information.
  • Support requests should include match IDs when gameplay issues are involved.
Mystery Chess may work with service providers that help operate accounts, hosting, multiplayer, notifications, diagnostics, support, and email. First-party analytics do not use session replay, fingerprinting, advertising pixels, raw IP storage, or raw support-message analytics events. Support and client-error reports may include message text, route, browser/device details, and user agent so the team can investigate. These providers may process data only to help us provide and protect the service. Contact info@mysterychess.gg for privacy, account, or support requests.

Younger Players

  • The website, Android app, and iOS app follow their applicable platform age and family-safety requirements.
  • Younger players should use Mystery Chess only with parent or guardian help where required.
  • If a parent or guardian needs account, privacy, deletion, export, correction, or support help for a younger player, contact support.
  • The later coaching/service marketplace will require separate age-safety, payment, tax, and guardian-consent review before activation.

Retention

  • Match records, moves, formations, ratings, and results may be kept as a permanent game record for gameplay history, integrity, disputes, and service improvement.
  • Purchase, refund, provider-event, and entitlement records may be retained for accounting, support, fraud prevention, and reconciliation as legally required.
  • If an account is deleted, we may retain match records while removing or de-identifying account details where practical.
  • Support messages may be deleted 6 months after they are successfully answered and closed, unless we need to keep them for safety, abuse, legal, dispute, or service-integrity reasons.
  • Ordinary diagnostic logs are generally kept for 30 days.
  • Security, abuse, and anti-fraud logs may be kept for 12 months, or longer for active incidents or legal holds.
  • Admin audit logs and founder/admin control-action records may be kept for 3 years.
  • Backups may be retained for 30 to 90 days depending on the provider and recovery window.
  • Account deletion and export requests are targeted for completion within 30 days, with extensions where legally allowed or operationally necessary.
