About this official website
This is a static website providing information and the player manual for Hakoshima. It has no site-specific analytics, advertising, account registration, or input forms. If you visit an external service, such as a distribution platform, that service's own policies apply.
Technical information used for delivery
The website uses Microsoft Azure delivery infrastructure. For delivery, maintenance, troubleshooting, and security, the hosting infrastructure may process technical information or logs such as IP addresses, access times, and request details. We do not claim that visiting the site involves no information processing at all.
Game save data
The initial game saves island state, reservations, policies, and history on your device. It does not implement accounts or cloud sync, and this official site has no mechanism for receiving the game's save data. The development browser version uses browser storage.
Deleting saved data
Uninstalling the app, clearing OS-managed app data, or clearing browser site data may delete game saves. The initial version has no account-based recovery or cross-device synchronization. Deleting this data may lose your island.
Future changes
If online features, analytics, or contact forms are added, this information will be updated to reflect what is actually provided. Check the latest information on this website for the current features and data handling.
