Cookie Policy
Last updated: July 21, 2026
This page explains the cookies and browser storage BackgammonWorld uses. The game itself relies on your browser's local storage — not tracking cookies — to work. Advertising partners may set their own cookies. You are always in control (see "How to control cookies" below).
1. What are cookies and local storage?
A cookie is a small text file a website stores in your browser. Local storage and session storage are similar browser mechanisms that let a site remember information on your device. We group all of these together as "storage" below.
2. Storage BackgammonWorld sets (strictly necessary / functional)
These are set by the game so it can function. They stay on your device, are not shared with anyone, and are not used for advertising or cross-site tracking.
| Name | Type | Purpose | Expires |
|---|---|---|---|
ca_token |
Session storage | Identifies your seat at a board so two browser tabs can play each other and a refresh reconnects you. | When you close the tab |
ca_player |
Local storage | A random guest identifier that keeps your guest rating in this browser. | Until you clear site data |
ca_auth |
Local storage | Keeps you signed in to your account. Removed when you log out. | Until logout / cleared |
ca_sound |
Local storage | Remembers whether you turned game sounds on or off. | Until you clear site data |
3. Advertising cookies (Google)
We promote BackgammonWorld with Google Ads, and this site includes Google's tag (gtag.js) to measure those ads (conversion tracking) and, where enabled, for remarketing. Google may set cookies in your browser for this. These cookies are set by Google, not by us, and are governed by Google's own policies.
- Learn how Google uses cookies in advertising: policies.google.com/technologies/ads
- Manage the ads Google shows you: Google Ad Settings
4. Affiliate links (Amazon)
Our "Boards we love" links point to Amazon. We do not set cookies for them, but if you click one, Amazon may set cookies on its own website to track the referral. That happens on Amazon's site and is covered by Amazon's cookie and privacy policies.
5. How to control cookies
- Browser settings: every major browser lets you block or delete cookies and clear local storage. This will also remove your guest rating and sign-in on this site.
- Personalized ads: opt out at Google Ad Settings, optout.aboutads.info, or networkadvertising.org/choices.
- Blocking the game's functional storage may stop features like reconnecting or staying signed in from working.
