Contact
CHESS/RUPT is operated by Ankur Gupta LLC, a United States limited liability company. While Apple's developer-account conversion is pending, the App Store may identify Ankur Gupta personally as the seller of record. For support, questions, bug reports, privacy inquiries, or feedback, email support@ankgupta.com.
Purchases and Refunds
CHESS/RUPT purchases are processed by Apple's App Store and StoreKit systems. Restore purchases from inside the app when available. Refund requests are handled by Apple. Unlimited Plays is a non-consumable purchase that removes the daily play limit while RevenueCat reports the Unlimited Plays entitlement as active. CHESS/RUPT does not display advertising.
Diagnostics
CHESS/RUPT keeps basic launch diagnostics on the device. In Settings, open Privacy + Credits and select Copy Diagnostics if support asks for them. Review the copied text before sending it; diagnostics are not transmitted automatically.
Game Center Features
Leaderboards and achievements may depend on Game Center, network connectivity, compatible app versions, and Apple service availability. CHESS/RUPT's core gameplay remains available locally when those services are unavailable.
Privacy and Terms
