Cookies & Local Storage

Koharusan keeps things minimal. We use only a tiny amount of browser storage to make the site work — no advertising cookies, no cross-site tracking and no selling of data.

What we store

• Age confirmation — when you confirm you are 18 or over, we save a flag in your browser's session storage (with a session cookie as a fallback). This stops the age pop-up from reappearing on every page during your visit. It is cleared when you end your session or close the browser, so the gate shows again next time.
• Cookie notice acknowledgement — when you dismiss the cookie banner, we set a small cookie (koharusan_cookie_ack) so the banner doesn't keep reappearing. It lasts up to 180 days.

What we do NOT do

• No analytics or advertising trackers.
• No third-party profiling cookies set by us.
• No collection of payment, banking or account credentials — we don't have accounts or take payments.

Third-party game frames

The demo games are embedded from a third-party game provider via iframe. That provider may set its own technical cookies needed to run the game in your browser. Those are controlled by the provider, not by Koharusan, and are used only to load and run the demo.

Managing cookies

You can clear or block cookies and site data at any time in your browser settings. If you clear ours, the age pop-up and cookie notice will simply appear again on your next visit. Blocking all storage may mean the age gate shows on every page.
