Storage on this device
Cookie policy
This page lists what Seven Nil actually stores. It is not a generic template. A draft lives on your device. Google AdSense and Vercel Analytics are the only third-party scripts loaded for visitors. Neither is a game control, and neither is required to finish a solo draft.
Storage we set ourselves
These entries are written by the game in your browser. They are not sent to an account, because there is no account. Clearing site data deletes the draft.
| Name | Where | What it keeps |
|---|---|---|
| seven-nil-save | local storage | Formation, picks, redraws left, phase, and the pitch theme. |
| seven-nil-name | local storage | The display name you typed before a friends room, capped at 18 characters. |
| seven-nil-mute | local storage | Whether dice and timer sounds are muted. |
| sn-host, sn-door, sn-join-name, sn-join-password, sn-join-partner, sn-notice, sn-kicked, and the room snapshot | session storage | Enough to reopen the tab you already joined. A password stays in that tab only so a refresh does not lock you out of a room you entered. It is not a user account. |
Google AdSense
One script is added after the page has loaded: pagead2.googlesyndication.com, client ca-pub-1391099021196311. The game does not draw an ad box and does not ask you to click. When the script runs, Google may set cookies or similar identifiers to decide whether an ad can be served, to measure it, and, if you allow it, to personalise it. That can happen even when no ad is visible. Loading the script does not mean this site has been approved.
If Google serves personalised ads, visitors in the European Economic Area, the United Kingdom, and Switzerland should see the consent message configured in the AdSense account before those ads. Refusing can limit personalised ads. You can also change that choice at Google Ads Settings, or use aboutads.info and youronlinechoices.eu. Google explains its own use of data from sites that use its services at policies.google.com/technologies/ads.
Vercel Analytics
The host may record a page view so we can see whether the site is up. That measurement is not used to build an advertising profile and it is not joined to your draft. Blocking third-party scripts stops it.
What we do not set
There is no login cookie, no shopping cart, and no tracker we wrote to follow you across other sites. Friends rooms share the room code, the names, and the picks with the people in that room. They do not publish your XI to the rest of the site. A contact message opens your own email app. It is not stored here.
How to refuse or delete them
Use your browser's site settings for seven-nil-self.vercel.app and clear cookies and site data. That removes the draft, the saved name, and the mute flag. Blocking third-party cookies limits AdSense and Analytics. The solo draft still runs, because the board reads local storage, not an ad cookie. A friends room can fail to restore after a refresh if session storage was cleared. That is expected.
Which script does which job
Count the third parties. There are two. The AdSense loader is the advertising script. Vercel Analytics is the page-view script. The game's own code is not a third party. It reads and writes the local storage keys in the table above. Adding another tracker would be a change to this policy first. There is no chat widget, no embedded video player, and no social pixel.
A solo draft does not need either third party. If both are blocked, you can still roll, pick, and simulate. You will not see an ad, and we will not see that page view. A friends room uses a direct connection between the browsers in the room for the live state. That is not a cookie. Clearing cookies does not delete the other person's draft. It can forget that this tab was the host, so open the room again from the code rather than expecting a refresh to know who you were.
Advertising cookies are the part people mean when they ask for a cookie policy. They are Google's, not keys this repository names one by one, because Google changes those names. What we can say for certain is the publisher ID, the one script tag, and the fact that the game draws no ad unit of its own. The matching public record is /ads.txt. The wider notice is the privacy policy.
