The small records behind your visit.

Your comfort settings.

oilchemists-comfort-v1 remembers selected sound, motion, effects, text-size, contrast, detail and reminder preferences. Signed-in preferences can also synchronise with the account. Local choices remain until changed or browser storage is cleared.

oilchemists-play-start and oilchemists-play-reminded are session-storage entries used to time play reminders. They expire with that tab session and do not store advertising profiles or game outcomes.

Essential first-party cookies.

oc_slot_guest connects this browser to its separate seven-day guest wallet. Clearing it ends access to that wallet and does not merge its chips into an account. oc_session keeps an account signed in for up to fourteen days. oc_csrf protects requests for one day. oc_adult remembers the adult declaration for thirty days, or through a longer chosen browser break.

These cookies use HttpOnly and SameSite=Lax, with Secure when served over HTTPS. Logging out revokes the active account session. Private guest support receipts use ic_support_* cookies lasting 90 days, scoped to their request page. Browsing and illustrative previews do not require the playable guest declaration.

Requested guest choices.

oc-next-up-v1 holds up to six selected guest-game identifiers in order. oc-favourites-v1 stores guest favourites; oilchemists-recent-v1 holds up to twelve recently opened games. oc-casual-scores-v1, oc-playroom-v2 and oc-controls-v2 can retain compatible earlier local results, saved rounds or control choices.

Signed-in records, favourites, recent visits and portrait choices are stored with the account. Clearing browser storage does not erase that account data. Private browsing or blocked storage can prevent device choices from surviving a visit.

Player preferences and interrupted requests.

Players may use local or session storage for selected controls, an interrupted request identifier and reminder dismissal. These records support consistent recovery and session reminders.

Sound, quick-spin and reminder settings may also be account-linked. Automatic previews do not write playable account rounds.

Manage the record you mean to change.

Device choices can remove requested local favourites, next-up choices and compatible guest records. The browser’s site-data controls can clear all local storage. Blocking essential cookies prevents sign-in and protected game actions.

Removing cookies does not delete server records or cancel a signed-in account break. Use account privacy controls or Contact for account-data requests. Review the device/account distinction before clearing a record you want to keep.

Optional Analytics and your choice.

oc-analytics-consent-v1 remembers your accepted or declined choice in this browser. It does not contain your account details.

If you accept, Google Analytics can set _ga and _ga_* cookies to measure public-page visits. Advertising storage, advertising personalisation and Google Signals remain disabled.

Use Storage choices to decline or withdraw consent. Withdrawal stops future measurement and removes accessible first-party Analytics cookies. Games and accounts remain available.
