Essential cookies and browser storage support secure access, interrupted-request recovery and your choices. Optional measurement remains off until you choose it. Essential account access does not depend on optional consent.

Animation preferences
The essential local-storage choice hachi_motion remembers whether you switched site animations on or off. It lasts until you change it or clear browser storage. Your system's reduced-motion preference takes priority.
Optional measurement
When no Analytics service is enabled, saving an optional choice does not create a tracker. If Analytics is configured, its current operation and storage are described here and in the Privacy Policy. Marketing storage is not used.
Change a choice
Open Cookie Preferences from the footer to review, accept, reject or withdraw an optional choice. Withdrawal stops future optional measurement under our control. It does not remove necessary account records, reverse a completed round or shorten a confirmed play restriction.
Browser controls
Your browser can clear or block cookies and local storage. Blocking essential cookies prevents protected sessions and forms from working. Clearing storage does not authorise bypassing a restriction. If a preference cannot be saved, optional measurement remains off and the service explains when an action cannot be completed. Effective 30 October 2026.
Google Analytics 4
Google Analytics 4 is provided by Google. Its tag is installed with optional storage denied. Public-page measurement starts only after Analytics consent; private account, recovery and play pages are excluded. Optional _ga / _ga_* cookies can distinguish visits for up to two years. We do not send emails, birth dates, credentials, recovery tokens or game outcomes. Google may process pseudonymous usage information outside the UK under its applicable safeguards. Advertising storage, Signals and ad personalisation remain disabled.
