Cookies and local storage
An itemised list of everything this site puts on your device, what each item is for, and how to get rid of it.
This site sets no cookies of its own. Not one. We use a different browser facility called localStorage, which behaves similarly from your point of view but is never sent to a server with your requests. The distinction matters: a cookie travels with every page load, whereas localStorage stays put until the page reads it.
What we store
Every key is prefixed with dominoes.v1. so you can spot ours in devtools.
| Key | Purpose | Lifetime |
|---|---|---|
dominoes.v1.game | Your match in progress, so a refresh or a closed tab does not lose it. | Until the match ends or you clear site data |
dominoes.v1.settings | Variant, opponent difficulty, target score, boneyard house rule. | Until you clear site data |
dominoes.v1.stats | Matches played and won, per variant and per opponent. | Until you clear site data |
dominoes.v1.daily | The date of the last Hand of the Day you solved, and your streaks. | Until you clear site data |
None of these contain personal information, and none of them are readable by us or by anyone else. They are strictly necessary in the sense that the features they support are the features you came for: a game that forgets your match on every refresh is not a working game.
Third-party cookies
There are currently none. No advertising, no analytics, no embedded video, no social buttons, and no web fonts loaded from another domain — the typefaces are the ones already on your device. The site loads nothing from any origin except its own. If that changes, this page will list the third party and its purpose before the change ships.
How to remove everything
Clear site data for this domain in your browser settings, or use the browser's “forget about this site” option. On most browsers you can also open developer tools, find Local Storage under the storage or application panel, and delete the dominoes.v1.* keys individually. Either way the deletion is complete, because there is no copy anywhere else.
Browsing in a private or incognito window works too: storage is discarded when you close it, so nothing persists between sessions. The game handles that gracefully — it simply will not remember your match.
See the privacy page for the wider picture of what is and is not collected.
