Privacy policy

Offline play

Saved games, campaign progress, display preferences and local play history are stored on your device. Offline play needs no account. Uninstalling or clearing app storage can remove this data.

Online friend matches and backups

Online play uses Firebase Authentication and Firestore. An anonymous identity or an email account identifies a player. Match rooms store player identities, game state, moves, clocks and results so both players can reconnect and play consistently. Optional progress backups store game progress linked to your identity. Anyone you give an invite code can use it to access its room.

Technical reporting

When Firebase is configured, usage analytics, crash diagnostics and performance reporting are enabled. They may include app version, device information and gameplay events. The current game does not provide separate reporting switches. These reports support reliability and troubleshooting.

Advertising

Development builds use Google test ads. Production advertising is not enabled until its configuration and consent requirements are completed. Builds that load AdMob may process device identifiers and interaction data under Google’s policies. Device privacy controls and applicable consent choices govern ad tracking.

Providers and sharing

Google Firebase handles authentication, cloud records and diagnostics. Google AdMob handles advertising where enabled. Online features necessarily transmit game data; offline game processing does not upload every saved game. We do not sell player account information.

Retention, deletion and your choices

Local progress stays until deleted from your device. Cloud matches and backups remain while needed to provide online features and handle support or abuse reports; this build does not promise automatic deletion on a fixed schedule. Contact support to request access or deletion of records linked to your account. We will verify the request and explain any records we must retain. Removing the app alone does not delete cloud records.

Security and international processing

Local data is protected by your device’s own security. Online providers may process data outside your country. No system can guarantee absolute security; keep your device updated and use care when sharing files or invite links.

Children and privacy rights

This is a general-audience product. We do not knowingly collect personal information from children under 13, or below the applicable local minimum age. Contact support if a child’s data was provided without appropriate permission. Depending on your location, you may request access, correction, deletion or restriction of personal data, withdraw consent, or complain to your local data protection authority. Contact support to exercise these rights; we may need to verify your request.

Changes and contact

We update the date when this policy changes. Material changes will be announced where appropriate. Use the support address below for privacy questions, access requests or deletion requests. Do not send private documents unless they are needed for your request.
