The math of roulette
Privacy policy
The calculators run in your browser without sending inputs to us. Contact messages and web requests involve limited personal data, described below. The site has no accounts, analytics or advertising.
Summary
- No account, registration or payment. The contact form collects only the information you submit.
- No analytics, advertising, social media or other third-party scripts. Only the contact form uses an essential security session cookie.
- Calculator inputs stay in the open page and are not sent to a server.
- The web server keeps short-lived access logs for security and operation.
- If you email us, we use your message only to reply.
What data is processed and why
Server access logs
Like any website, the server that delivers these pages records each request: the IP address, date and time, requested address, response status, referring page and browser user agent. These records are used to deliver pages, diagnose faults and protect the service from abuse. Under the current server configuration, log files are rotated and kept for about 10 days.
Calculator inputs
Stakes, wheels and bets you enter are processed only by JavaScript in your browser. They are not transmitted, logged or written to browser storage. Reloading the page restores the default example. Copy result writes text to your clipboard only when you press it.
If you write to contact@rouletteodds.co, we receive your email address, name if included and the content of your message. We use it to reply and to act on corrections, and we delete correspondence when it is no longer needed for that purpose.
Contact form and security
The contact form sends your name, email address, subject and message to the first-party server only when you submit. Accepted messages are passed to the configured mail transport. The form uses an essential, session-only security cookie to prevent forged requests. Abuse limits use a keyed hash of the request IP address and timestamps, kept for at most 24 hours; message contents are not stored in those records. See the cookie policy.
Third-party services
Pages, fonts, images and scripts are all served from rouletteodds.co. The site does not load content from content delivery networks, font services, analytics providers, advertising networks or social media platforms. The site is hosted on a server operated for Roulette Odds; the hosting infrastructure processes request data as described above.
Links to external sources, such as the rule documents on the about page, lead to sites with their own privacy policies.
Sharing and transfers
Personal data is not sold, rented or shared for marketing. Log data may be disclosed only where required by law or to investigate abuse of the service.
Your choices and rights
Depending on where you live, you may have rights to ask what personal data is held about you, to have it corrected or deleted, to object to or restrict its use, and to complain to your data protection authority. Because the site keeps so little data, most requests concern email correspondence or recent server logs.
To make a request, email contact@rouletteodds.co. We may need enough detail, such as the date and approximate time of a visit, to locate a log entry.
Children
The site discusses gambling and is intended for adults. It does not knowingly collect data from children.
Changes to this policy
If the site adds analytics, accounts, advertising or any other service that processes personal data, this policy and the cookie policy will be updated before the service is enabled, and consent will be requested where required. Last updated October 11, 2026.
