Privacy Policy
M-Nova is a separate four-tile mahjong game in the RIICHI ORBIT SERIES.
1. On-device saves
Your player name, crew appearance and accessories, cabin and furniture, Lumina, cards, routes, match records and preferences are saved on your device. No account registration is required. Progress can be reset in Settings. Resetting M-Nova does not delete RIICHI ORBIT saves or the shared cosmetics container.
2. Online matches
For friend matches, public lobbies and match requests, servers hosted on Cloudflare process a random player ID and authentication information, display name, crew appearance and equipment, invitation number, participation state, game actions, skill choices, scores, results and connection times to provide play and prevent abuse. Other players see your display name, appearance and information needed to play. Unrevealed opponent hands and the tile wall are not shared during play. Technical information such as IP addresses may be processed for abuse prevention and troubleshooting.
3. RIICHI ORBIT sharing
Compatible apps on the same device share crew appearance, owned and equipped accessories, cabin interiors and placements, and owned furniture using a local shared container. Sharing is on by default and can be disabled in character editing. Display names, Lumina, cards, routes and records are not shared. This sharing does not send cosmetics to a remote synchronization server and does not synchronize different devices.
4. Optional rewarded ads
Google AdMob provides optional rewarded videos that can increase rewards after a solo victory. Ads are not shown during the first experience or friend matches. The advertising SDK may process approximate location inferred from IP addresses, device identifiers, advertising and interaction data, crashes and performance information for ad delivery, measurement and abuse prevention. Consent choices are provided where applicable and can be changed from the advertising privacy settings when available.
5. Permissions and unused information
Contacts, the photo library, microphone and precise location are not required. The app has no chat or image-posting feature. Local customization and core solo matches can be used without sending an online player profile.
6. Retention and security
Online information is processed as needed for play and recovery, abuse prevention, usage statistics and troubleshooting. Contact us below to request information about or deletion of display-name and player-identifier records. Third-party connection logs follow each service’s settings and policies. Do not share private authentication or invitation information.
