Cookie policy

Essential access

jp_session is a first-party, HttpOnly, SameSite=Lax cookie. It holds an opaque session identifier, not your password or a browser-controlled balance. Guest sessions and remembered sign-ins last up to 30 days; ordinary sign-in expires after one day. Secure is used on HTTPS.

Protected-period continuity

jp_device is a first-party, HttpOnly, SameSite=Lax cookie lasting up to one year. Its opaque identifier connects this browser to server-stored protected periods. It is essential to preserve a requested break through session changes and does not create an advertising profile.

Your choices

Cookie choice and the permitted analytics state are stored with your server-side session or account. The light lens, Evening Seal and reminder are account preferences, not third-party tracking. No advertising storage is offered.

Optional analytics defaults to denied. Accepting optional analytics has no effect when no provider is enabled. You can decline or withdraw without losing normal access to the product.

Essential browser-tab storage

The game uses sessionStorage keys jp_request_{player}_{game} for an interrupted request identifier and jp_session_clock_{player} for your session reminder. They contain no password, payment information or authoritative balance. They remain within this browser tab and normally disappear when its session ends. They keep retries and reminders working without optional analytics.

Browser controls

You can clear cookies in your browser. Doing so may sign you out and remove access to an unregistered guest session. It does not cancel an account exclusion. Use Cookie Preferences for ordinary choice changes rather than clearing functional access storage.

Policy updates

This inventory is updated when storage behavior changes. Updated 10 November 2026. Read the Privacy Notice for account and support data, or use Support if you need help with a privacy request.
