Privacy

A description of what this site actually does with data, which is very little.

Calculations

Every calculator on this site runs in your browser. The balances, prices and multipliers you type are processed on your own device and are not transmitted to any server. There is no submission step, no calculation API, and nothing to store.

If you use a “copy shareable link” button, the values you entered are placed in the URL so the link reproduces your calculation. Those values are impersonal quantities — a price, a multiplier, an assumed RTP. Anyone you send that link to can see them, which is the point of the feature, so do not put anything in a calculator field that you would not want to share.

Accounts and cookies

There are no accounts, no sign-in, and no newsletter. This site sets no cookies of its own and uses no local storage to identify you.

Third parties

Pages load our self-hosted analytics script from a dedicated analytics host that we operate. There are no advertising tags, social widgets, embedded media, or third-party analytics services.

Production pages are delivered through Cloudflare. Cloudflare may inject a same-origin /cdn-cgi/ script on responses it treats as containing an email address. That is host behaviour, not a tracker this site configures. Method citations on this site use a space-delimited identifier and version so they are not treated as email addresses.

Outbound links to operator sites and to source documents are ordinary links: following one takes you to a third party with its own privacy practices, over which this site has no control and no visibility.

Analytics

We use a self-hosted Umami service to measure canonical page paths, token-like campaign labels, external referrer origins, device categories, pageviews, and a small allowlist of interactions such as calculator completion and source-link use. Calculator inputs, copied values, free text, raw query strings, destination URLs, and account details are dropped before analytics is sent.

A per-site pseudonymous session identifier is made from transient network and device signals and rotates every week. The analytics database does not store raw IP addresses or raw user-agent strings. It keeps device, browser and operating-system categories, country and, for U.S. visits, state or region. It does not collect city or precise location. Analytics records are deleted after 13 months.

We do not sell or share analytics data, use it for targeted advertising, enable session replay, identify you, use fingerprinting, or join your activity across our sites.

Analytics cookies

Umami does not set analytics cookies. No analytics consent banner is shown. Local browser storage used by calculator links is not sent to analytics.

Server logs

Whoever hosts this site will keep ordinary web server request logs, which typically include IP addresses, timestamps and requested URLs. That is a function of the hosting arrangement rather than of anything this site does, and it applies to any website you visit.

Reddit and other communities

The copy and share features on this site produce plain text and a URL for you to paste wherever you like. Nothing is posted automatically, no community is monitored, and no user of any platform is tracked, profiled or identified by this site.

Children

This site discusses gambling mathematics and is not intended for anyone below the legal age to gamble where they live. The site has no account or newsletter signup.
